2017 Kia Optima Engine Problems

Your engine seized and locked up, which you report is a known issue with Kia's Theta II 2.4L GDI engines. Kia refused to cover engine replacement, saying you hadn't completed a required KSDS ECU update recall — but Kia admits they didn't have your contact information on file, so you never received the recall notice. You believe Kia failed to properly notify you of this safety recall and is unfairly denying warranty coverage. The fix would likely involve a complete engine replacement or reprogramming of the engine control unit, depending on what Kia determines.

Your engine is burning through oil at an excessive rate—about 1 quart every 1,000 miles—requiring you to constantly top it off to avoid engine damage. Your check engine light came on, and a mechanic found that your PCV valve has failed and oil is coating your spark plugs. The dealership is refusing to perform a required diagnostic test under Kia's engine settlement unless you first pay $3,300 to replace the turbo, even though the turbo wasn't problematic before. Addressing this will likely require replacing the PCV valve, spark plugs, and possibly other engine components once the dealership performs the diagnostic.

Your 2017 Kia Optima's engine has developed serious internal problems shortly after purchase, including a loud knocking sound from failing bearings, excessive oil consumption, and power loss. The engine may stall, seize, or potentially catch fire due to the bearing and piston ring damage. Your dealership has refused to repair or replace the engine despite these safety concerns. Engine repair or replacement will be needed to resolve this issue.

Your 2017 Optima Hybrid experienced a "check hybrid system" warning while driving at highway speed, causing the car to enter limp mode and lose power. You had to safely pull over on the freeway shoulder. A mechanic diagnosed a failed hybrid inverter (costing $2,177 to replace) and also detected engine knocking, which may indicate faulty factory rod bearings covered under Kia's extended warranty. The repair will likely involve replacing the hybrid inverter and potentially the engine if the rod bearing defect is confirmed.

Your engine completely shut down while you were driving. After having the engine replaced and other repairs done, you discovered this was part of a class action lawsuit. You've spent two years trying to recover the repair costs and the money you paid for the vehicle.

Your engine started having problems just three months after you bought the car. You've noticed jerking and shaking, a metal clicking noise, loss of power while driving, and declining overall performance. Kia has been attempting repairs for a year without fully resolving the issue. The fix will likely involve engine diagnostics, possible valve or timing component inspection, and potentially engine rebuild or replacement.

Your car lost power while driving at highway speeds and went into limp mode (reduced power mode) three separate times, with the check engine and hybrid warning lights coming on and off. The dealer couldn't reproduce the problem during testing, so no repair was made. The issue may involve the engine control computer or related sensors that need diagnostic scanning to identify the root cause.

Your engine is burning through oil much faster than normal—the dipstick showed completely dry before you hit 5,000 miles, requiring you to add oil to prevent engine damage. The dealership suggested waiting until the engine knocks or the knock sensor fails before addressing it, which risks serious engine damage if oil levels drop too low while driving.

Your 2017 Kia Optima is losing engine oil at an unusually fast rate — you're needing to add oil almost every 2 weeks — without any warning light initially alerting you to the problem. A dealer inspection found that oil is leaking onto the catalytic converter, and the manufacturer has been notified of a potential connecting rod bearing issue. The repair will likely involve inspecting or replacing internal engine components and sealing the oil leak.

Your engine is burning through oil at an unusually high rate, requiring you to add oil 3-5 times per month. The excess oil is fouling your spark plugs prematurely, forcing replacements every 10-12 months instead of the normal interval. This excessive oil consumption suggests an internal engine problem that will eventually lead to engine damage if not repaired.

Your 2017 Optima has been consuming oil constantly, requiring you to repeatedly replace spark plugs and ignition coils over the past year. You've also had the valve cover gasket replaced, and your diagnostic scanner shows code P1326. Your dealership says they won't replace the engine unless it starts knocking, but you're concerned about being stranded if you wait for that to happen.

Your 2017 Kia Optima is hesitating and stalling, especially when starting from a stop, with the check engine light on. The dealership diagnosed a faulty knock sensor and replaced it, but the problem persisted immediately after. Kia then recommended replacing the knock sensor again and performing a tune-up, but the car still runs in "limp home mode" and remains unsafe to drive. The engine was replaced two years ago under warranty for excessive oil consumption, and you believe this current issue should also be covered under Kia's stated lifetime warranty on replacement engines, but the dealership is declining to do so. A proper diagnostic scan and engine evaluation will be needed to determine if the engine requires replacement or if additional sensors and ignition components need service.

Your engine is burning oil faster than normal, and oil has accumulated on your spark plugs. This is causing the oil to be consumed during operation. Your mechanic may recommend a decarbonizing service to help clean carbon buildup inside the engine that could be contributing to the problem.

Your engine is consuming oil faster than normal between oil changes, and you've noticed oil leaking underneath the vehicle. The low oil pressure warning light only comes on when you press the brake pedal, which is unusual. A mechanic checked but couldn't find a visible leak, though your engine recently needed five quarts of oil added. The issue likely involves an internal oil leak or excessive oil consumption that may require engine inspection or seal replacement.

Code P1326, Faulty Knock sensor on 2.4GDI

The car stalled out

My Kia optima fe 2017 has been consuming a lot of motor oil it takes a quart every 2 to 3 weeks and of if I drive it more than average it needs motor oil sooner

My vehicle is experiencing engine issues consistent with the known Theta II GDI engine defects — including rod bearing failure piston rings engine stalling, I understand that Kia has offered extended warranty coverage through the engine defect settlement, provided the Knock Sensor Detection System (KSDS) update was installed before failure. I am unsure whether this update has been applied and would like to confirm my eligibility. I respectfully request: 1.Confirmation of KSDS update installation on my VIN 2.A review of my eligibility for engine inspection and coverage under the extended warranty 3.Assistance with coordinating service and coverage at my local dealership (LeBlanc Kia, New Iberia, LA) I am the second owner of this vehicle and want to ensure I am treated fairly under the known warranty extension guidelines. Thank you for your support. I look forward to your prompt response.

I purchased a 2017 Kia Optima from Deal Makers Auto Sales in Georgia in February 2024. The vehicle broke down within 3 months. I later found out it had four open safety recalls that were never disclosed at the time of sale. This is dangerous and deceptive, and the dealership refused to take responsibility or make repairs.

Engine stalled out while driving lyft. Got passenger to their destination safely, however lyft is my only source of income big risk to stall out on a highway.

The contact owns a 2017 Kia Optima. The contact stated that while attempting to start the vehicle, the vehicle lost motive power with no warning light illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000.

I was driving on the highway, the check engine light started flashing and the car lost power. This created a very dangerous situation because I could not go the speed limit and could not get off the highway since I was in the middle lane. We went and had the check engine light checked and were told the code was P1326.

I was driving on the highway and randomly my car started to shake very badly and i couldn’t go faster than about 30 mph. My engine light didn’t turn on until i turned the car off and back on after finally making it home after almost getting hit by cars trying to make it back home. I sent it to get looked at and they said that it’s misfiring pretty severely and that kia had a recall on an engine/motor awhile back for my car and to take it to a dealership. I contacted KIA customer care but the only recall I see when I look up my VIN # is for the trunk recall.

1.) What component or system failed or malfunctioned? Engine failure due to excessive oil consumption and/or a malfunctioning Knock Sensor Detection System (KSDS). •The engine failed at only 50,000 miles due to internal issues. •The KSDS system triggered a flashing check engine light, but Kia refuses to cover the repair despite known past issues. •Kia engineers and the dealership confirmed the engine failure but are denying warranty coverage. The vehicle is currently at the dealership and available for inspection. 2.) How was your safety or the safety of others put at risk? •A flashing check engine light appeared, indicating possible catastrophic engine failure while driving. •Loss of engine function on the road could have led to an accident. •The KSDS system was designed to prevent this type of failure, but it failed to stop the damage in time. •If the engine had completely failed at highway speeds, it could have created a dangerous situation. 3.) Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by the Kia dealership. •The dealership confirmed that the engine has failed and needs to be replaced. •A tech line case was opened with Kia engineers, who confirmed the failure. •Kia refuses to cover the repair, claiming it is a "top-end failure" instead of a "rod bearing failure." 4️.) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Yes, it was inspected by the Kia dealership and Kia engineers. •A tech line case was created, and Kia engineers reviewed the issue. •Kia admitted that the engine failed but refused to cover the repair under warranty. 5.) Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, a flashing check engine light appeared due to the Knock Sensor Detection System (KSDS). •The same warning code had previously appeared while

My Engine is burning a quart or more of oil a week. Since my last oil change I have put in 15 quarts of oil. I called KIA service department and they said there is nothing they can do unless my check engine light is on.

I have been dealing with an engine issue for almost two years now, dealership is telling me I need to wait till a barring goes out for the engine to be replaced at no charge. Car does not go over 60 mph, oil is burning like crazy

The contact owns a 2017 Kia Optima. The contact stated while the vehicle was parked, the vehicle stalled. The oil change warning light was illuminated. The contact stated that an oil change was needed almost every two weeks. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the alternator needed to be replaced. The vehicle was repaired; however, the oil change warning light was illuminated. The vehicle was taken to a dealer where the vehicle was diagnosed; however, the result of the diagnostic test was unknown. The vehicle was repaired; however, the oil change warning light remained illuminated. The contact research and was made aware of NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 80,000.

Yes, the issue has been confirmed by Kia. They acknowledged the high oil consumption and indicated that the engine requires a rod bearing replacement. However, Kia does not want to fully recognize the problem. I have taken the car to another mechanic who confirmed that the ignition coil has burnt on cylinder number 3 and identified it as an engine failure along with the high oil consumption.

The contact’s daughter owns a 2017 Kia Optima. While the contact’s daughter was driving at an undisclosed speed, there was a loud rattling sound coming from the front end of the vehicle. The check engine warning light illuminated. The contact stated that while attempting to start the vehicle, the vehicle failed to start on the first attempt. The vehicle started on the second attempt was able to be driven. The vehicle was taken to the dealer who determined that the engine rod had failed, causing complete engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact became aware that the vehicle was included in an undisclosed Product Improvement Program for a software update; however, the contact was unaware of the software update which voided the Extended Warranty for the engine repair. The manufacturer was made aware of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

A auto repair shop said my Kia Optima has a bad knock sensor which is a common problem with those cars. My safety and others was put at great risk when I suddenly lost power on the freeway Problem was confirmed at an independent service center Has not yet been inspected by manufacturer Warning message came up at the same time as losing power

Took the car to the dealership to diagnose an issue that I know Kia has a settlement for which is the engine class settlement and the dealership is trying to say the cause of known issue is from another source so they do not have to cover the cost of a replacement engine. The dealership is saying my option is to pay 8-10k for a new engine when it should be covered under the lifetime engine warranty which they confirmed I have. Engine light popped up the day of taking it to dealer. The engine has the possibility of seizing putting the driver or others at risk of serious accident.

The engine Is losing oil. Taking it to KIA dealership and other repair shops around our area and she has to have her oil changed every thousand miles because the oil is going somewhere but they don’t know where because there’s no leakage anywhere. I see there’s 100 of other complaints about this key should be responsible. Please indicate what we can do about this doesn’t have that many miles on it.

Driving highway speed (75) after work may 23rd 2024 when my car just randomly stop accelerating and I pulled to the side of the highway and I heard a weird engine knock sound coming from engine . I turned the vehicle off and back on and it was still doing the same thing then it just cut off and wouldn’t start no more. I reached out to Kia cooperate to find out that it’s an extended life time warranty on the engine of the make of my car for rod bearings failure. I contacted Kia of Pelham Al to get an appointment to bring it in I drop it off June 9th , service app was June 10th. They failed to give a rental car … leaving me with no way to work …

Turbocharger failed at 90000 miles because fan assembly was bad. May have happened when dealership replaced high pressure fuel pump. Fan sheared and metal parts got in the engine about a thousand miles after that.

I was driving on the highway, and my oil pan storage plug fell out of my car. All of the oil leaked out of the engine causing my engine to seize up while I was driving. The dealership says my vehicle is out of warranty, and will not replace it, and that it will cost me $12,000 for a new engine

MY 2017 OPTIMA IS CONSUMING OIL INTO THE PISTONS AND PISTON RINGS WHICH IS SOAKING THE SPARK PLUGS CAUSING ENGINE MISFIRE, MY MECHANIC STATES IT WONT BE LONG TILL THE ENGINE GOES OUT, I TALKED TO KIA AND THEY TOLD ME THE CAR HAS TO BE SEIZED OR KNOCKING FOR THEM TO REPLACE THE ENGINE, KNOWING ITS A PROBLEM. I WANT MY CAR FIXED AS ITS A KNOWN ISSUE ACROSS ALL OPTIMAS.

Ms. Nadine Thomas, who is running for District 44 in Georgia, has served on the Georgia House of Representatives and the Georgia State Senate is my boss and know what I have been through with my vehicle and has heard from KIA in Athens GA that there is nothing they can do. I have a 2017 KIA Optima that I have been having problems with since around 06/2022 or a little before. I have been getting oil changes and putting oil in the vehicle every week or every other week. It finally took a mechanic to tell me it is an issue with Kia's and a recall due to the replacement of the motor because the cars are losing oil. I do not have an oil leak but losing it every week and replacing it and it is expensive for an oil change and a gallon of oil constantly. I have reached out to KIA Manufacturer and case was denied, BBB and KIA denied it all the way, through where I went has far as to the attributor. Georgia Attorney General and they sent a letter to the Bulldog KIA in Athens and they said I have to go through the process of either hearing a thumping noise or motor light flashing constantly and or car shuts off before my motor can be replace. None of this has happened. I had to pay out of pocket for a tune up which was over $300 in Sept 2023 and again early this year 2023 and no reimbursement but it’s on my KIA receipts due to oil consumption (leaking of oil) it’s causing me to keep replacing the spark plugs. Renting vehicles when they would have to keep my vehicle to replace the spark plugs, and missing time from work. They will not compensate me for it, replace the motor, and or provide me another vehicle. I feel also because I am a woman that I am racially profiled, I have been very professional, calm, and provided more than enough time, effort, and providing all the information to KIA and I am not getting nowhere or through to anyone that will hear me or understand what I am going through. Previous NHTSA ID Number is 11518826, awaiting for response back from Ossoff Office.

The contact owns a 2017 Kia Optima. The contact stated that while his wife was driving at an undisclosed speed, the low oil pressure warning light illuminated. The vehicle was taken to an independent mechanic; however, the failure could not be duplicated. The vehicle was taken to the dealer; however, the contact's wife was asked to complete and record information for daily engine testing. The contact's wife completed the daily engine and oil pressure testing for ten consecutive days. The contact's wife submitted the information to the dealer and the manufacturer. The vehicle was taken back to the dealer and an oil consumption test was requested. The vehicle was at the dealer for several days; however, a diagnostic update was not provided. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 92,973.

The engine code p1326 code popped up after coming to a stop the same code associated with the Kia engine recall but my vin isn’t covered

Every time after I get an oil change I’m constantly having to put oil in it because it goes dry every 2 days and my check engine light stays on before and after oil change, randomly shaking soon as I turn the car on then the oil light comes on every time I go over a speed bump! The car slams on breaks when it wants and has even did it when in fast traffic on the highway.

I was driving at 65MPH on the highway when the warning lights went flashing on my dashboard with "Check Hybrid system", "!HEV", and check engine light. I pulled over to the side of the highway and had a tow truck took it to the dealership to check out. Kia dealership did a diagnostic and mentioned the hybrid engine failed to convert from hybrid to gas and vice-versa. I am at 165,531 miles and Kia is charging me $13,000 to fix it. I am over the warranty of 150,000 miles. The "Check Hybrid system" message has been ongoing since 2021 and Kia mentioned it has to do something with the hybrid battery and Kia no longer makes a replacement battery for the Kia hybrid optima 2017. All Kia does it reset the system for the "Check Hybrid system" message to go away. After a few weeks, the message will appear again on the dashboard. I have upload an image of the dashboard with all of the warning lights. I need help as this is costing to much to fix.

Entered on to the highway and accelerated to get up to speed. Check engine light started blinking and could no longer accelerate.

The contact owns a 2017 Kia Optima. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, the engine was consuming an excessive amount of engine oil. The contact stated that the engine was consuming one quart of engine oil every two days after an oil change was performed. The vehicle was taken to AutoZone, where it was diagnosed that the detonation sensor was faulty. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 96,500.

I was driving down the highway and my car just went out in the middle of traffic I almost got into a accident with my kids in the car.there were no warning lights or anything on before it went out I finally pulled over in the far right lane and my car wouldn’t turn back on and started flashing various lights on the dashboard and still wouldn’t turn on I had to call triple A and have the car towed that put me in a very dangerous situation especially with my children in the car

Excessive Oil Consumption: Could cause Engine failure, Engine Seizure due to lack of oil. I have a 2017 Optima with Excessive Oil Consumption issue. I noticed the car is consuming excessive oil, for the third time. Many people had reported this issue, leaving customers with expensive repairs. This issue could cause Engine failure, Engine Seizure due to lack of oil. I took the vehicle to the dealer, (Kia) recommended additional services and kept the vehicle overnight for testing. These additional services were outside the normal maintenance interval and are expensive. Quick History: -As of 12/26/2023 Vehicle was dropped off due to excessive oil consumption, this time before the service interval was due. -2017 Optima/ 83,200 Mi -All Oil changes and scheduled maintenance performance at normal interval, sometimes sooner due to the Excessive oil consumption. -Car is for personal use/ normal driving - No Leaks detected in the Car

The contact owns a 2017 Kia Optima. The contact stated while driving approximately 35 MPH, the check engine warning light illuminated. The contact reset the check engine warning light however, the light became illuminated again. The vehicle was taken to a dealer and the contact was informed that the engine oil was low and needed to be topped off. Additionally, the dealer offered to perform an oil consumption test. The vehicle was not repaired. The contact stated that he had researched online and related the failure to an engine design flaw. The contact requested that the dealer attempt to repair the engine and was refused. The contact was advised by the dealer to drive the vehicle until the engine failed and then he would be placed under consideration for a manufacturer engine replacement program. The manufacturer had been informed of the failure. The failure mileage was approximately 76,000.

Driving down the interstate, the vehicle started to decelerate and the engine light started flashing. Got it to a mechanic and he started that it was a knock sensor failure P1326 code. Same as the recalls, but my vin number was not included in the recall report. Already had this vehicle in for excessive oil consumption. Paid for the dealer consumption test. They said it only burned a qt. and that was acceptable. In 1000 miles. Have done my own 1000 mile test and have been burning 1.5 or more qts. on three separate tests. Something has to be done about these engines. This is dangerous when going interstate speed and dropping to 20 mph in heavy traffic.

Oil from engine does not cycle through the engine and instead it foams up and comes out of the top of the engine and I need to put oil in my car every week.

The contact owns a 2017 Kia Optima. The contact stated that while driving at 60 MPH, the vehicle inadvertently decelerated and then lost motive power. The check engine warning light was illuminated. The contact was able to restart the vehicle and drove to the residence. The contact stated that the vehicle jerked while driving. An independent mechanic diagnosed the vehicle at the residence and retrieved DTC Code: P1326, and the contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the knock sensor was previously replaced for the same issue; however, the failure recurred. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN and that the vehicle was not covered under warranty. The failure mileage was 100,670.

The engine on this vehicle caught fire while the vehicle was parked and not running. It had previsouly been drive for approximately 4 hours throughout the day but at the time of the incident there were no warning dashlights present. It is currently available for inspection, however depending on the length of this invesitagion it may no longer be available as i work with my insurance company determing next steps. My safety and the safety of other were put at risk by and open flame and smoke that occured during the fire. Ultimately the Fire Department were required to put out the fire. Approximately 8 months ago the engine was replace by the dealership Summit Place Kia East in Michigan due to an open recall for a knock sensor issue. I suspect this vehicle will be a total loss.

I was driving my kiaon a very busy interstate. When I was going around 65miles per hour and all of a sudden I lost all power it went from 65 miles per hour to 30 all at once when I hit the gas peddle the car went in jerks finally I got it back up to 55 but it only goes in a jerking motion and r. Very small hill u come to u lose power and it goes jerking . I thought several times I would get rear ended by the vehicle behind me I'm scared to drive this and when the car is running and you step out of the car the smell of gas is very strong and it is using a lot more gas than it mostly does . This happened to me September 20th2023.

The contact owns a 2017 Kia Optima. The contact stated that the oil warning light was frequently illuminated on the instrument panel. The contact took the vehicle to an independent mechanic and was informed that oil had leaked into an engine cylinder. The mechanic informed the contact that a Technical Service Bulletin had been placed on her vehicle in relation to the failure and referred the contact to a dealer for assistance. The contact called Pride Kia of Lynn and Herb Chambers Kia of Burlington and was informed that the vehicle was out of warranty. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 122,000.

Complete engine failure while driving 70mph down the freeway. No lights came on before engine started shaking, knocking, and failed. We were stranded at a gas station. We checked oil and there was none. (This was shocking because we changed oil regularly and car had just received complete oil change several weeks prior) We bought enough oil to drive it to nearest auto mechanic shop. He inspected the car and said complete engine failure and that we needed to contact KIA immediately. Spark plugs were burnt and melted more than he had ever seen. He said this is a recurring problem with their engines. (A few months prior to this incident, check engine light came on and car had a slight sputter during acceleration. We took the car to local repair shop. Car received complete tune up weeks prior to incident and check engine light was resolved.) Car was taken to Kia dealership in Little Rock, AR. Diagnosis: Major oil consumption caused engine to overheat and lose pressure/fail. Engine is non-repairable. New engine will cost $10,000. Kia will not back their product. After investigating further, I have found a Facebook group with tens of thousands of people with similar incidents in their Hyundai/Kia cars. This is a dangerous problem and KIA needs to be held accountable. The most recent class action settlement DOES NOT cover engine failure due to major oil consumption, only rod bearing failure. Where is the oil going? There were no leaks detected, no oil light to warn me. Where does the oil go? Burning up through exhaust? Surely that violates some sort of environmental standard that car manufactures should be abiding by. These cars are dangerous to consumers, and bad for the environment. I’m stuck with a car that I still owe money on that is worthless. If I spend $10,000 to repair, they will put the same engine back in the car and I will repeat the cycle of engine failure and loss.

My car does not accelerate easily and struggles with basic speed. I took it to a mechanic and am being told that my turbocharger has failed and must be replaced because there is fuel in my oil and there may be damage to my engine as a result that would require me to replace the engine. This is the second time in less than 2 years that this has happened since I have owned this vehicle. The mechanic says the engine could seize up or catch fire at any point and that I will have to have the oil drained, flushed, and replaced, hopefully have the fuel leak found and repaired, then the turbo replaced. Only once all of that has been done will I know if the engine will still be operable. The first time this happened it was repaired at a Kia dealership in Denton TX under warranty. The vehicle is no longer under warranty and should not have this problem every year.

Engine needed to be replaced as part of the recall for knock, however they said because the repair was done on a subsequent work order and the first one was for a failed AEB module that none of the repairs are covered. I'm out over $13,000 for what should have been warrantied

My vehicle came up with a check engine light blinking. I took it to a Kia dealership where they put the ksds update in. A week after driving it, I started experiencing loss of power and the check engine light came back on. But this time not blinking. My car accelerates slowly, it is a struggle to get to 30 mph. My engine is making loud noises as if I am flooring the gas pedal when going 10 mph. Hills are impossible and dangerous to drive up. I took it in where the man told me my oil was empty, when just the day before it was full. I ran the code reader which came up p0010 for a camshaft. Now I’m being told it’s the entire top motor needing replacement due to “no oil”. I saw online recalls for this exact issue on the engine. It states of a lifetime engine warranty for this qualifying engine problem. I called the dealership where the lady informed me that there is a third party company that makes warranty coverage decisions, and that they make the decision on if it’s covered based on how much they will have to pay. If it’s a lot, it’s on me. Basically my engine failure qualifies but they don’t want to pay the amount of repairs. So I’m stuck with paying thousands for a hazardous car that I’ve only had for 8 months.

In the last year, my car has been in the shop countless times. I have had my knock sensor replaced and fixed multiple times. There is a significant lag when taking off from a complete stop, and there have been times that I cannot exceed more than 60 MPH. I have had my car serviced the exact way it states in the owner's manual without fail and still cannot find a cause for why my car is experiencing all of these issues. To get the motor to accelerate is nearly impossible 90% of the time. There is currently a recall on some other 2017 Kia Optimas for the Knock Sensor but there is not one on mine, even though mine has been replaced and fixed several times.

My 2017 Kia Optima is running out of oil between oil changes which I do on time. Before my next oil change it has no oil reading on the dip stick. I just had this occur again and I had to add two quarts. The oil light only blinked on for a second. When I checked it, no oil was reading on the dip stick. Taking it to auto store I was told by worker his mother has the same problem with her 2016 Kia and they replaced the motor in a recall. Mine is a GDl engine. Something needs to be done with these engines. I'm having the same problem a lot of other people are having.

I have replaced my cars spark plugs and all things related to the spark plugs for the last 4 months. After taking NY car for maitnence over and over again at the Santa Fe Kia in Santa Fe, NM. The car has cintun3d to have issues. My car is currently having a issue with the knock sensor and wire harness from the Diagnostic I received from my Local Auto Zone in Las Vegas, NM. The car does not drive correctly and sputters. I have took it to be be maintenence over and over again and spent over 500.00 for the maintenence this last four months. And it seams it has been one issue after the other my car is under 70,000 miles. I give it proper maintenence and oil changes.

Have lost 4 qts of oil in the last month. Brought it to the mechanic and they couldn’t find any leaks. They said the only way I’m losing oil, is that the car is burning through it. They’ve seen the same issue with these cars. Only 65,000 miles on it.

I only had the car 2 years. In the last two years, I have been getting my oil changed every 3 months. The oil goes out fast. I'm a local driver so I don't go too many places. When I brake or stop, my oil light blinks, when I'm completely out. This month (June 2023) it's staying on. When the temperature gage rises half way the oil light comes on and stays on. I just recently put oil in, so it's not empty or low. Nor is it overfill. I was told it's the GDI Engine. Honestly, idk where the oil is going and why it's running out so fast. And I just learned today a friend of mines KIA is starting to do the same.

The contact owns a 2017 Kia Optima. The contact stated that on two separate occasions while driving at undisclosed speeds, the steering wheel became stiff and seized before the vehicle stalled. The vehicle was towed to the dealer where an unknown software update was performed, and the anti-theft software was updated. The vehicle was repaired. The contact then stated that while driving approximately 60 MPH, the vehicle started to hesitate. The check engine warning light was illuminated. The contact then stated that every two days he had to add 1-quart of engine oil. The vehicle was taken to the dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the vehicle was not covered under warranty, but no further assistance was provided. The failure mileage was approximately 90,000.

I have the oil problem that everyone else has. I drive everyday for work and every week I have to put oil in my car. I am coming up on 100,000 miles. My car hesitates and this is the second battery I have had to put in it in three years.

The contact owns a 2017 Kia Optima. The contact stated while driving approximately 75 MPH, the contact attempted to accelerate to change lanes however, the vehicle failed to respond. The contact stated that the vehicle started to decelerate and sputtered as if the vehicle before the vehicle stalled. The contact stated that several unknown warning lights illuminated. The vehicle was pulled over to the side of the roadway and towed to the dealer. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the entire engine needed to be replaced. The vehicle had not been repaired. The contact stated that the vehicle had been consuming approximately one quart of engine oil every 500 miles. The manufacturer had been informed of the failure. The failure mileage was approximately 167,000.

To whom this may concern, I have had my car for several years now and the oil consumption is outrageous. I burn 5 quarts of oil every 2-3 weeks. Every time I had taken my car to get oil changes I am told that my specific engine has always been an oil guzzler. Well fast forward to last week. I was driving my car to work when the engine light came on and my car no longer wanted to accelerate. I pulled over and turned the car off. I changed out the battery considering maybe this was the issue. This did not fix the issue. I ended up towing my vehicle to the Kia Dealership in Hurst. I was told that I had 2 broken cylinders and my engine is not replaceable. My question to the service tech was how would my cylinders just break? I was given no answers but a number to call. This number ended up being Kia Consumers who don’t call me or answer the line. I have had the knock sensor replaced which should cover me for any extended warranty that is said to be in place but I am pulled in circles. I need help getting my car through the motions.

This is how I am feeling and the reason for being an unhappy customer. I shouldn't have to keep buying gallons of oil to put in my car every other day. Oil change was done on Sept 6th along with spark plugs put in due to oil consumption. Took my car again to Kia on Sept 21th because there was no oil in my vehicle, so they put oil in. Then on Sunday Oct 2nd I had to spend $44 on a gallon of oil because there was no oil in it once again. It’s a recall and should be fixed regardless if it doesn't shut off while I'm driving, hearing the knocking noise, and or the check engine light comes on. First I was told to bring it or call if the check engine light comes on and stays on now I am told it has to come on and stay blinking. I can be on the highway with my family or infant grandchild and my car shuts off what if I cause and accident, kill someone, or myself or family dies in my car. Would you rather have a lawsuit or fix the problem before that happens. I have talked to other mechanics that have went through it with their customers and they fixed the issue with the Kia's before it gets to this point. Still has of now every two weeks I am buying $44 worth of oil to put in my car. Even from the advisor that I have been dealing with at Kia named Beau stated that my spark plugs issue was from the oil, and he always stated oh its getting close to the motor going out. Now my car is hesitating and its doing the same thing as it was before the new spark plugs except the check engine light isn’t on. I can’t afford to keep putting oil in it and constantly getting oil changes. Just from the receipt the Kia Manufactured attached isn’t the only time that I have been to Kia or contacted the manufactured company regarding this. It took me to take it to a different shop when I can’t stating to Kia the issue than finally they said it’s a recall on the car. It’s also a recall on the fuel pump and I advised them and still didn’t order the part or fix that as well. Still having issues now

The contact owns a 2017 Kia Optima. The contact stated while driving approximately 50 MPH, the vehicle began to violently shake with a knocking sound coming from the engine compartment. The check engine and the engine oil pressure warning lights flashed but disappeared. The contact veered to the side of the road and towed the vehicle to an independent dealer where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and a case was filed. The failure mileage was approximately 104,000.

My car has an oil consumption problem with more that a quart every 1000 miles. It has around 94000 miles on it now. Took it to dealers and they say its normal with Kias. Have not pulled it apart because I do not have the money.

I took my car in for a recall, Kia let me leave with an unsafe vehicle. Everything in the recall is happening to my car and it is extremely unsafe. These things were happening before I went in for the recall and after I left from having the recall checked. "Abnormal knocking noise from engine," "illumination of oil pressure warning light." The HEV warning light comes on and tells me to turn off my car immediately which has happened many times in unsafe conditions i.e. being in the middle of the highway in the rain. The check engine light came on but it comes on, then is off, then comes back on. There is a recall for the engine, oil is leaking into the engine on to the hot exhaust which can cause fire to the engine. This started happening not long after getting the car, this is why I brought it in for the recall. I made the appointment right away but the closest appointment was in about 2 months. It continued to happen after they "checked" the recall. The oil pressure light illuminates, the traction control light illuminates, and then 5-10 seconds later a warning comes across the dashboard saying "Check Hybrid system. Turn off engine. HEV!" Now I am being told I would have to bring my car in today, let the car sit at Kia for 4-6 weeks until they can diagnose it, and they will not give me a loaner car. I cannot be without a car for 4-6 weeks, this isn't my fault, and I cannot go pay for a rental car for 4-6 weeks. They are saying I cannot make an appointment for this, which makes no sense to me because I initially made an appointment to get the recall checked. My safety, the safety of my three children, and other passengers has been put at risk because I am driving and all the sudden these lights come on, the car starts dinging, and tells me to turn off the engine. This constantly happens when I am on roads where I can't just pull over quickly. I have been on the highway a few times and this has happened. Couldnt get over immediately and the car was barely moving.

My car is consuming oil crazily and way too often. I just bought this car from a dealership 4 months ago and it is getting worse and worse. Losing power. I’m scared to drive it on the highway due to stories from other people and their kias. I have no choice but to drive it because I have to work. I need help.

The vehicle will shake during acceleration. It comes without warning and will cause the check engine light to flash and stay on for about a minute. It goes away on its own. However, there do not seem to be any stored codes, according to my personal OBDII scanner. The dealer refuses to take it in because there is no check engine light. However, this has happened in several occasions and could lead to an accident. The dealer appears to be waiting for the warranty period to run out.

The contact owns a 2018 Kia Optima. The contact stated that while driving at an undisclosed speed, black smoke was coming from the exhaust pipe and the vehicle was jerking. The oil warning light was illuminated. The contact added engine oil. The vehicle was taken to an independent mechanic, where oil was found on unknown sensors and on the coils. The contact was informed that an oil change was needed, and the filter needed to be replaced. The vehicle was repaired; however, the contact stated that after starting the vehicle, the check engine warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the engine needed to be replaced; however, the vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was 110,569.

The contact's son owns a 2017 Kia Optima. The contact stated that while her son was driving at an undisclosed speed, the vehicle stalled. Additionally, the vehicle was consuming an excessive amount of oil. The vehicle was towed to the dealer, where it was diagnosed as needing a new engine. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000. The VIN was not available.

Purchased 2017 Kia Optima from DriveTime in 2021. Car burns a lot of oil, as I am constantly getting the oil changed or adding oil. A few months after purchase, all of a sudden it loses power & decelerates while I’m driving on the interstate. Had to pull over & let car sit for a few minutes. Every 10 mins I had to do this. Had it checked out the next day at Kia dealership & was told nothing was wrong. I let the car sit for about a month b/c I was afraid to drive it. Finally decided to drive it & the issue seem to resolve itself. Now almost 6 months later it happens again. Car wouldn’t accelerate over 40 mph. Car warranty agent advised to take to Firestone( in-network repair shop). Mechanics say the engine is gone & they called warranty company , & then they say take to Kia dealership. Dealership states if it’s the engine there are 75 cars with same issue ahead of me. They ran diagnostics 2 weeks later & said it’s not the engine but gave me a long laundry list of other issues. Said new wiper blades needed (not true , the new blades were just put on 1-2 months prior, said oil change needed, but that was fine 3 days before I took it to them , & more issues with a invoice total of over $6500!! They kept my car over 2 months with no call to update me after I advised everything they said was wrong actually wasn’t. I called daily & left messages with no return call. Finally got someone on the phone in the Service dept & was told it still isn’t the engine but just needed a software update. I still don’t trust it & afraid to drive it. But yet & still the VIN # is still not on the recall list. Regret the day I walked on the DriveTime parking lot. Nothing but issues from day 1. Too bad I couldn’t list them all here.

I am the second owner of this car. According to carfax it has been well maintained at kia since day one. I have owned it for almost 6 months and it has been sitting at the dealership for 2months due to engine failure. There is a rod knock and sludge build up not for lack of maintaining it but from not being driven enough. I am being told it is a $16,000 repair. These cars are warranties for 10 years 100,000 miles (it only has 72,000 miles on it) but since I'm not the original owner that warranty doesn't follow. This is a misrepresentation.

my check engine symbol started to flash, my car was not going over 2 RPM, took it to my mechanic, when he scanned it, he told me it's showing P132600, and that the engine might be failing, I have a KIA Optima 2017 with 70k miles on it. thanks god I wasn't on the expressway.

The contact’s sister-in-law owns a 2017 Kia Optima. The contact stated that while attempting to start the vehicle, the engine failed to turn over. There was no warning light illuminated. The vehicle was towed to the dealer to be diagnosed and the mechanic determined that the engine needed to be replaced. The vehicle was repaired. Additionally, the contact stated that his sister-in-law was informed that the VIN was included in a recall; however, the contact’s sister-in-law was not notified of a recall prior to the failure. The manufacturer was notified of the failure and the contact was informed that the recall notification was sent to the prior owner due to the contact’s information not being updated. The failure mileage was approximately 100,000.

ENGINE MALFUNCTION: It is available for inspection at Lee Kia, Greenville, NC On January 20, 2023, my car experienced a blinking Malfunction Lamp (MIL) when I was out of town at an appointment in Williamston, NC, 16 miles away. This is the indicator, when blicking, warning for the Knock Sensor Detection System software that was put on my car on December 20, 2018 that the engine is malfunctioning. After my appointment, I drove the car one mile to AutoZone in Williamston, NC and they plugged in their sensor and got the P1326 code. While at AutoZone, I called the Service Center at Lee Kia of Greenville, NC and reported what had happened. They told me not to drive the car and have it towed to them, 1 hour away. My tow service would only allow towing ½ mile to the Dodge Dealership. I called Lee Kia Service Center and talked to a [XXX], Manager of the Service Center. She said it had to go to a Kia Dealership to be covered under the Engine Replacement Recall. On Saturday, January 21, 2023, I called the Service Center at Lee Kia and asked for an update on the car. The Service person told me that it had arrived and they would diagnosis it either that day or on Monday, January 23, 2023. On Monday, January 23, 2023 in the early afternoon, I called Judith the Manager of Lee Kia Service Center and asked for an update on the car. She told me it would take 4 months to diagnosis the car and I would not be able to have a rental car until it was diagnosed. When I asked why it would take 4 months to diagnose my car, she said she had 15 cars ahead of me. She said she only has two technicians that can diagnosis and it takes one day to diagnose a car. The mathematics of that did not add up. My car should be diagnosed in 16 business days, not 4 months. She refused to help me.

Engine oil consumption: I have owned this car since November 2022 and took my Kia Optima to Valvoline for an oil change in December 2022 because my oil light came on and it turns out that my car was 3 quarts low and they topped my oil off for me. 1 month (January 2023) later my oil light in my car did NOT come on but the check your engine light did and it seemed like it was losing power. So in order not to damage the engine I had it towed to my home when we arrived at my home oil started coming out of the car at the bottom while it was still on the tow truck lift the car was facing down hill

I took my Kia Optima to Century 3 Kia for an oil change in August of 2022. 2 months later my oil light comes in my car but I still have 2000 miles left until next oil change. I called Century 3 Kia complaining of a flashing oil light. They told me since I still have 2000 miles until the next oil Change, the mechanic must’ve just forgot to reset the car after they did my oil Change and that’s why it’s flashing. They told me to come down so they can reset it. They reset it and sent me on my way without even checking my oil. After leaving I still had the oil light on so I took it to a mechanic close to home to check my oil and I barely had any in there. I topped the oil off and the light went away. I sent Kia consumer an email after this visit complaining of the bad service I received and how they made me drive with no oil. I attached the email. I then scheduled an appointment at a different Kia dealership - South Hills kia for a new oil change and told them to please check my oil because I believe it could be burning. South Hills Kia performed a multi point inspection and gave me an oil change and told me my car had no signs of leaking or burning oil and is good to go . Not even a month after the new oil change my engine blows and the dealer told me it’s because of burning oil and I’ll need a whole new engine. My car is a 17 Optima with 61,000 miles and just a mout of warranty . It’s always been up to date on oil changes. It’s upsetting because I trusted Kia and now my vehicle is down because of them and they want me to pay.

I purchase the car at the end of November of 2022 from drive time. I was driving on January 8th 2023 and the car speed reduced and the check engine light started flashing

On June 5th 2022 as I was traveling out of state with my wife and daughter the car lost power on the highway. I pulled over to the side when safe and noticed whitish grey smoke puffing from under the hood by the hinges. Being a fire lieutenant, I recognized this as the car being on fire. We exited the vehicle, my daughter was asleep in the back seat, so it was a panic to wake her and make sure she got out away from traffic. Within the 3 minutes I was on the phone with 911 the car was engulfed. A few minutes after the first Chief arrived the fire had reached the fuel tank and the vehicle exploded, approximately 8 minutes in. I opened a claim with my insurance and with Kia America. Kia has taken the blame but refused to replace the vehicle, instead offering me $15000 for the car with only 57000 miles on it. After fighting with Kia for 3 weeks during my claim they finally provided me with a rental vehicle paid for by their insurance. To this date they have not paid for said rental and I am now on the hook for the $930 charge. This event has caused much undue stress on me, I already have cardiac issues, my wife and daughter still have nightmares from the event. Kia inspected the vehicle which is totally burned, they found it to be an engine failure causing oil to spill onto the hot exhaust. They accepted blame. There was no warning, no noises, no lights. I never received a recall notice, I found out about the recall from my insurance after the fact. Kia has been less than helpful.

The contact owns a 2017 Kia Optima. The contact stated that oil was leaking from the vehicle onto the driveway of her home. The vehicle was taken to the dealer, and the mechanic stated that the spark plugs needed to be replaced. The sparks plugs were replaced but the failure persisted. On another occasion, the contact noticed that oil was leaking from under the vehicle again, and the vehicle was taken to the dealer to be diagnosed. The contact was informed that there was oil cylinder #3 spark plug. The spark plug and PCV valve was replaced; however, the failure recurred. The vehicle was taken back to the dealer and the contact was informed that the engine needed to be replaced. The vehicle was not replaced. The manufacturer was contacted and stated that the contact would receive a call back. The failure mileage was 93,226.

The contact owns a 2017 Kia Optima. The contact stated that while driving at an undisclosed speed, the vehicle made knocking sounds with the check engine, ABS, and traction control warning lights illuminated. Additionally, the engine was consuming an excessive amount of engine oil. The vehicle was towed to the dealer; however, the vehicle was not diagnosed nor repaired and remained at the dealer.

Hey, while driving my vehicle the engine light started blinking and there was a delay in my acceleration and when I got to 60-65 mph my car begins to stall and will NOT drive any faster. Also I sent my car to the dealership for repair 08/15/22 and they still haven’t diagnosed the car yet even after I received letter in mail for recall. Please help thank you

The motor seems to have a knocking noise accompanied by constantly burning oil and sparks plugs. Constant misfires and check engine light appearing during the year after replacing spark plugs and ignition coils.

The contact owns a 2017 Kia Optima. The contact stated that while driving at 65 MPH, the vehicle entered limp mode as several warning lights illuminated on the instrument panel. Due to the failure, the contact had the vehicle towed to the dealer and was informed that his vehicle was under NHTSA Campaign Number: 21V844000 (Engine), which they linked to his failure. Despite the recall repair, the failure occurred on two additional occasions. The vehicle was taken back to the dealer where an additional software update was performed; however, the failure continued. The manufacturer was notified about the failure and sent an investigator to inspect the vehicle. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 112,000.

On November 16, 2020, Lucy Robinson was driving her 2017 Kia Optima when she started seeing smoke. She pulled into a gas station and the engine was on fire. The fire department extinguished the fire. A cause and origin was conducted and it was found that the fire originated within the engine compartment. The fire was caused by the release of heated oil coming from the leaking PCV located at the top portion of the valve cover.

Check Engine Light started FLASHING on and off constantly. The car started to have a hitch and felt like it had less power. I had the code checked and it had a code of P1326. This appears to be an issue with the engine and could be quite serious.

The contact owns a 2017 Kia Optima. The contact stated after the oil was changed at 1,200 miles, the vehicle stalled and there was an excessive oil consumption failure. The contact replaced the oil more times than the manufacturer recommended interval. The oil warning light was illuminated. The vehicle was taken to an independent mechanic and the contact was informed of an excessive oil consumption failure with the Hybrid models only. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

Car overheated without any forewarning or indication lights being displayed. Causing hydraulic and engine to fail. Kia is not taking responsibility for the rod bearings causing the overheat. They are saying at the dealership my car was not part of this recall. They refuse to fix it and want me to pay for the new engine myself. Three mechanics have already stated that the hydraulic can be caused by the rod bearings. They are denying the claim

Engine Failure after KSDS in March 2022 Update Error Code P1326 (2 times in May and June 2022), BSDS Error with HEV Warning Light Shut Off Engine to prevent damage. Engine burned 2.5 quarts of oil in 3 weeks and 1500 miles. Vehicle went into “limp mode” or “safe mode” to prevent further damage. Engine failure at 102k miles. Error is currently being added by KIA North Austin. KIA reproduced the error P1326.

The contact owns a 2017 Kia Optima. The contact stated that while operating the vehicle the low oil level warning light flashed and occasionally the vehicle would not properly respond while depressing the accelerator pedal. The contact checked the engine oil dipstick and discovered that there was very little oil in the engine. The vehicle was taken to the local dealer who performed an oil consumption test and indicated that the vehicle was consuming one quart of oil per one-thousand miles and that the rate of consumption was within a normal range. The vehicle was not repaired. The contact stated that since the oil consumption test was performed the failure had become progressively worse. The manufacturer was notified of the failure. The failure mileage was 50,000.

EXCESSIVE oil consumption. More than 1 quart every 1,000 miles. I am having to change my spark plugs about every 3 months to keep this car going. I've been to Kia twice and spent thousands of dollars. It has fixed nothing.

Engine is consuming excessive oil. That could cause internal parts of the engine to wear faster because of less lubrication and could lead to an engine failure while driving, which could lead to engine stopping and loss of propulsion which could cause an accident. The car went through a oil consumption test with a Kia dealership and failed by consuming more than 1 qt of oil in a 1000 miles interval. The Kia dealership proceeded to do a combustion chamber cleaning procedure and re-did oil consumption test and it failed again. They also had requested service record which where provided. Even though Kia has a service bulletin on that matter, the service advisor at the Kia dealership said that the manufacturer declined the claim. Right now I’m constantly refilling oil in the engine which is also an additional expense. The first time I noticed the issue was in February, 2022 when the low oil pressure alert came on.

The Engine burns oil at a rate higher than the recommended oil change interval. I have had the dealer perform multiple consumption tests. The car passed all three even though it burns around a quart every 1000 miles. I had them clean the combustion chamber and paid for the costs myself but that did not resolve the issue. This seems be a known defect in the engine and is causing me a lot of problems monthly. A recall needs to be issued to fix this problem.

Oil consumption in my vehicle is well above 1 qt per 1000 miles. This is a known problem but Kia engines and Kia doesn't take responsibility for it. The oil light never comes on and the car runs out of oil every 1500 miles. It's not leaking, it's being consumed. Kia does not see it as a problem, even though there are so many reports. Please expand the recall for 2017 Kia's.

I had got on the freeway when I got to my destination I got off the freeway and was waiting for the green light my car started shakeing and shut off. I was able to turn it back on

The contact owns a 2017 Kia Optima. The contact stated that while driving at approximately 70 MPH, the speed decelerated independently while the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the accelerator pedal needed to be repaired. The vehicle was repaired however, the failure persisted. The vehicle was taken back to the dealer where they informed the contact there was an unknown software update. The vehicle was repaired but the failure recurred. The vehicle was taken back to the dealer where it was diagnosed that the knock sensor software needed to be updated. The vehicle was repaired but two days later the failure recurred. The vehicle was taken back to the dealer where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

Unknown … Right in the moment I started the car. My car turned on the check engine light and it started a fault as if it wanted to turn off, it shakes and the engine works without power. Since that moment it’s doing it constantly.

My Kia Optima was burning three (3) quarts of oil for every 1,200 miles driven. I brought the vehicle to Willowbrook Kia and they stated that they would need to do an oil consumption test. After the 1st test, it showed that I burned 3 quarts after 1,200 miles driven. Kia completed an intake carbon test and had me drive it for another 1,000 miles. After the 2nd test, it showed that I burned 1.5 quarts of oil after 1,000 miles. Willowbrook Kia stated that the engine needed to be replaced and it will be under warranty. They rented me a car which they paid for and it took me to call after 1 week in a half and they stated that the vehicle is not covered under warranty as I am the 2nd owner of the vehicle. The gentleman (Vic) at Kia told me the only way to get Kia to replace the engine is to drive it until their is no oil and the engine seizes. I explained to him that I drive on the expressway everyday and that is kind of like an accident waiting to happen. No accident has happened as of yet, but thought I would at least try and send a complaint your way. If there is nothing that can be done, I completely understand, but was trying to avoid a possible accident in the future.

My 2017 Kia Optima Hybrid began losing oil rapidly (more than 1 quart a week), and then knocking. There was never a warning light or an engine light. The mechanic at Kirby Kia (the dealership) confirmed engine knocking in the lower pistons. Kia will not honor the 100,000 mile drive train warranty because I am the second owner, and there is no recall on the hybrid engine. However, it's irrelevant that they won't cover the cost of the engine since they are not making engines available to anyone outside of the recall, so I cannot fix my car. I'm a little confused on why this engine is withheld for the recall, but mine is not recalled.

ENGINE HAS TOO MUCH OIL CONSUMPTION , WENT TO DO MY OIL CHANGE 200 MILES BEFORE IT WAS DUE AND THE AUTOMOTIVE PLACE TOLD ME THERE WAS NO OIL ON MY DRIP STICK. ALSO HAVE A RATTLING NOISE IN MY ENGINE WHEN I ACCELERATE. NOISE HAS BEEN HAPPENING FOR A FEW MONTHS BUT THEY CAN'T SEEM TO FIND A PROBLEM.

I'VE TAKING MY LEASES VEHICLE INTO CARSON OF KIA 3 TIMES FOR OIL LIGHT THEY REPLACED THE OIL PRESSURE SWITCH TWICE OF THE 3 TIMES WHILE DRIVING AFTER THE CARS WARMS UP I GET TICKING NOISE YOU CAN HEAR THE BETTER WHEN WHEN DRIVING NEXT TO A RETAINING WALL AT THIS I'VE FILED A COMPLAINT WITH THE MANUFACTURER AND AFTER REVIEWING THE WORK ORDER FROM THE DEALER ALL THEY OFFER ME WAS 2 MONTHS OF CAR PAYMENT WHICH I DECLINE SO I'M CONTRACTING NHTSA FOR HELP AND ADVISE

MY 2017 KIA OPTIMA CAUGHT ON FIRE ON OCTOBER 15, 2020. I WAS DRIVING TO THE STORE AND HEARD A TICKING SOUND AND SOME NOISES. THE CHECK ENGINE LIGHT ALSO CAME ON. I PULLED OVER IN THE LEFT TURNING LANE ON THE HIGHWAY TO EXIT THE VEHICLE. I HEARD A POPPING SOUND AND SAW FLAMES. I EXITED THE VEHICLE AND IMMEDIATELY CALLED 911. MY CAR BURST INTO FLAMES.

I JUST PURCHASED MY 2017 KIA OPTIMA TWO MONTHS AGO. I WAS DRIVING TO WORK TODAY IN THE CENTER LANE ON THE HIGHWAY AT ABOUT 65 MILES PER HOUR. OUT OF NOWHERE WITHOUT WARNING MY CAR SHUTTERS AND THE CHECK ENGINE LIGHT COMES ON. MY VEHICLE IMMEDIATELY LOST ACCELERATION AND GOT DOWN TO ABOUT 45 MPH AND WAS FALLING FAST. CARS WERE FLYING AROUND ME AND I WAS AFRAID FOR MY LIFE, I HAD TO FIGHT MY WAY OFF OF THE HIGHWAY TO GET TO SAFETY. I WAS LOOSING SPEED THE WHOLE TIME AND ALMOST GOT INTO AN ACCIDENT. I GOT INTO A PARKING LOT AND LET THE CAR REST. I CHECKED ALL MY FLUID AND OIL AND EVERYTHING WAS FULL/ FINE. I DECIDED IT WAS A FLUKE AND TO TAKE A BACK ROAD TO WORK. BIG MISTAKE. THE CAR WOULDN'T GO OVER 20 MPH AND I PRESSED THE ACCELERATOR DOWN WITH NO LUCK. THEN ALL OF A SUDDEN THE ACCELERATOR WORKED AND MY CAR SPED UP TO 25 MPH FROM 15. THIS WAS ALSO EXTREMELY DANGEROUS. I PULLED BACK OVER AND CALLED RICK CASE KIA. MY BOYFRIEND USED HIS CODE READER AND FOUND OUT IT WAS THE KNOCK SENSOR. THATS WHEN I FOUND OUT ABOUT THE LAWSUIT. I SCHEDULED AN APPOINTMENT AND GOT A TOW TRUCK TO TAKE THE CAR TO THE DEALERSHIP. WHEN I ARRIVED I MENTIONED WHAT HAPPENED AND SAID THAT I JUST FOUND OUT ABOUT THE LAWSUIT FROM THIS ISSUE. THE ONE SERVICE MANAGER FREAKED OUT THAT I MENTIONED THE LAWSUIT IN FRONT OF OTHER CUSTOMERS AND JUMPED TO EXPLAINING HOW MY CAR WAS ALREADY HANDLED AND THIS ONE ISSUE IS COVERED FOR LIFE. THIS MEANS THEY ADMITTED TO KNOWING ABOUT THIS LIFE THREATINING RECALL WHEN SELLING ME THE CAR. IF THEY DISCLOSED THIS CRUCIAL INFORMATION THAT I HAD THE RIGHT TO KNOW, I NEVER WOULD HAVE BOUGHT IT. THEY WILL ATTEMPT TO FIX IT AGAIN BUT I AM TERRIFIED TO DRIVE IT.

THIS IS MY NEW CAR, I BOUGHT IT BECAUSE MY GOOD EXPERIENCE WITH THE 2 KIA SPECTRA WE BOUGHT FOR WORK MORE THAN 10 YEARS AGO AND BECAUSE THE BEAUTIFUL SHAPE AND COMFORD INSIDE. BIG MISTAKE !!! WHEN YOU ARE IN A DATE WITH SOMEBODY IS BETTER TO WAIT , BEAUTY SEXY BODY NOT ALWAYS COME WITH A GOOD SOUL OR ENGINE. ONE WEEK BEFORE MY FIRST CAR PAYMENT DRIVING CHARLOTTE OCT. 20 , DOWN I-77 MY CAR BEGAN TO SLOW DOWN, THEN ENGINE LIGHT CAME ON, FEW SECONDS LATER THE BATTERY LIGHT AS WELL, LOW OIL LIGHT, ALL THE ALARMS GO ON LIKE A CHRISTMAS TREE. IN MIDDLE OF THAT CHAOS LOOKING FOR A SAFE PLACE TO STOP THE FRONT DRIVE TIRE HIT A POTHOLE AND CAUSED DAMAGES TO THE BOTTON OF THE CAR. FEW MINUTES LATER THE CAR STARTED AGAIN AND I MOVED IT TO A BUSINESS PARK WHERE IT DIED 100 % . I PAID TO A TOW COMPANY TO MOVE IT TO MY HOUSE AND NEXT DAY TO THE KEFFER KIA DEALER HERE IN MOORESVILLE WHERE I BOUGHT IT. IF THIS HAPPENS DRIVING AT THE MOUNTAINS I CAN KILL SOMEBODY OR KILL MY FAMILY WITH A FAULTY CAR AND THE DEALER KNOWS ABOUT THE ENGINES PROBLEMS BUT THEY NOT TAKE AND REFUSE RESPONSIBILITY FOR THEIR CARS, NOW THE SECOND CAR PAYMENT IS COMING AND IS NOT WAY TO GO TO WORK WITHOUT A CAR. BECAUSE ALL THE INFO. FROM THE CAR COMPUTER IS GONE THEY SAY IS MY FAULT. ANY IDEA WHAT TO DO?

MY 2017 KIA OPTIMA BROKE DOWN ON 10/7/2018 AND THE CAR WAS TOWED TO FUCCILLO KIA. THEY REQUESTED A COPY OF MY LAST 3 OIL CHANGES BECAUSE THEY STATED THAT THERE WAS GUNK IN THE ENGINE. I SUBMITTED THE RECEIPTS AS REQUESTED AND A CLAIM WAS FILED WITH KIA'S CONSUMER AFFAIRS DEPARTMENT. THE CLAIM WAS DENIED ON 10/17/2018 BECAUSE INSUFFICIENT MAINTENANCE. I CALLED KIA CONSUMER AFFAIRS TO ASK WHY IT WAS CONSIDERED INSUFFICIENT MAINTENANCE. THE REP COULD NOT OR WOULD NOT TELL ME WHY. I WENT TO THE DEALERSHIP AND NO ONE WOULD HELP ME KEPT REFERRING ME TO THE CLAIMS DEPARTMENT. THEY AGREED TO SUBMIT AN APPEAL SO THE DISTRICT MANAGER WOULD REVIEW MY CLAIM BUT THAT WAS DENIED WITHIN 24 HOURS STATING THREE OIL CHANGES WERE NOT ENOUGH. I ONLY SUBMITTED THE LAST THREE RECEIPTS AS THEY REQUESTED. IN TOTAL, I HAD SIX RECEIPTS. I DID THE RUN AROUND AGAIN AND AFTER STATING I WOULD NEED EVERYTHING IN WRITING (CLAIM DENIAL, WARRANTY INFO, ESTIMATE OF DAMAGES) FROM KIA AND THEY STATED THEY WOULD NOT GIVE ME ANYTHING IN WRITING.

MY CAR HESITATE WHEN PULLING OUT IN THE STREET ..HAPPENS OFTEN AND WHEN THE ENGINE IS AT NORMAL TEMP, NOT WHEN COLD. IT STARTS OUT FOR ABOUT 3 FEET THEN THE ENGINE STALLS, DOES NOT QUIT RUNNING, JUST STALL FOR 3 TO 5 SECONDS. GIVE IT GAS AND NOTHING, THEN ALL AT ONCE IT TAKES OFF. VERY DANEROUS. SOME DAYS IT PERFORMS GREAT THEN THE NEXT IT STARTS THE HESITATION AGAIN. MAKING AN APPT TO TAKE IT BACK IN TO HAVE IT CHECKED NEXT WEEK.
