2021 Kia Soul Transmission Problems

Your transmission has failed twice in the time you've owned the car, and at 34,400 miles this is concerning. When the transmission fails, your car loses power while driving at high speeds, which creates an unsafe situation. Your piston rings were also replaced as part of a recall. The replacements have not resolved the underlying issue.

[XXX], the vehicle was delivered to Crain KIA dealership located in Conway, Arkansas, due to failure of engine to start (engine would turn over but not run). I scheduled a service appointment for May 20th at 0930, for the car to be evaluated/troubleshot. While at the KIA dealership service desk, I discussed KIA SAFETY RECALL SC336, and that my VIN# was effected by the recall (verified by speaking with KIA Customer Care representative) and by using NHTSA's VIN/Recall search engine. At that time, I disclosed that the car was a SALVAGE TITLE vehicle, but was restored, looked nearly brand new and was otherwise operational prior to the engine "no start" condition (4 months of ownership). The service team at the dealership confirmed the SALVAGE TITLE via "Carfax", however they noted that KIA's internal VIN/TITLE database DID NOT REFLECT the car as salvaged. Crain Kia dealership then decided to submit the car for KIA's SAFETY RECALL inspection and possibly warranty work since the vehicle has not exceeded the 5yr/60,000 mile limited basic warranty. Unfortunately, the dealership did not open a "tech-line case' until approximately 15 days later. Tech-line communication between the service technician and KIA's engineering/recall rep, directed the dealership to perform an engine wet/dry compression test (due to deficient piston oil-rings). On June 5th, Crain KIA notified me that the resulting 'LOW" compression test results indicated that the piston rings were faulty, and that the engine would need to be replaced. Additionally, they told me that the vehicle would NOT BE ELIGIBLE for factory warranty due to the SALVAGE TITLE and that I would be responsible for engine change costs. Moreover, the dealership's service team charged me for the cost of the compression testing. I have thoroughly reviewed the KIA recall SC336 documentation as well as NHTSA's 25V-099 bulletin and verified that neither notices proclaim, exclude or deny coverage to salvage title vehicles.

Our 2021 Kia Soul experienced complete engine failure without warning. The engine suddenly lost power and became inoperable while driving. The dealership's diagnostic testing identified a camshaft sensor code, but no definitive cause for the catastrophic failure was provided. We believe the failure is related to internal engine damage potentially caused by defective piston oil rings, consistent with NHTSA Recall Number 25V099000. Kia has not conducted a full internal engine inspection to rule this out. The vehicle is in Kia's possession and is available for inspection upon request. The sudden engine failure occurred without warning and caused a complete loss of power while the vehicle was in motion. This could have led to a serious accident had the incident occurred in heavy traffic or on a high-speed roadway. The inability to accelerate or maintain control of the vehicle poses a serious safety risk to both the driver and others on the road. Yes. The vehicle was inspected and diagnosed by a Kia dealership. While they identified a camshaft sensor code, they did not perform a full inspection to determine the internal cause of the engine failure. They declined to attribute the issue to the known piston oil ring defect and refused to repair it under the recall. Instead they want to submit it to the TechLine for the power train warranty. We had to spend hours calling places and collecting information of all oil changes and maintenance on the vehicle over the last 4 years. We can show a CLEAR pattern of regular maintenance of the vehicle. The vehicle has been inspected by an authorized Kia dealership. No inspections have been conducted by the police, insurance representatives, or other third parties. There were no warning lamps, dashboard messages, or performance issues prior to the engine failure. The vehicle was regularly maintained and had been operating normally up to the point of the incident.

I dropped off my 2021 Kia Soul at the dealership where I purchased it to address a nationwide recall, which states: “The piston oil ring(s) may have been incorrectly manufactured, potentially damaging the engine cylinder wall. This can lead to increased oil consumption, abnormal engine noises, engine seizure, and possible fire from oil leaking onto hot exhaust components. Loss of drive power and/or fire increases crash and injury risk.” My vehicle has shown multiple symptoms, including rough running, significant shaking, illuminated check engine and oil lights. On 01/02/23, I brought it in, but the dealership found no stored codes and took no action. On 04/20/23, a code for a cylinder 1 misfire was found, but because the issue wasn’t present at that moment, no repairs were made. On 10/05/23, spark plugs and fuel pump were replaced under warranty. No further issues occurred until 02/14/25, when the same symptoms returned. I was told I’d be charged for a diagnosis and they likely wouldn’t find anything, so I left without service. On 04/09/25, the symptoms reoccurred. I dropped off the vehicle on 04/10/25 and paid out-of-pocket for a rental until 04/14/25. On 04/14/25, after being told earlier that work couldn’t be done because the engine hadn’t cooled to 55°F, I was later told the recall was completed and the vehicle was safe—despite ongoing issues. I fear for my safety and the safety of others. I believe my vehicle needs an engine replacement and is unsafe to drive. The recall letter states inspection and software update should take 1–2 hours, and engine replacement 8+ hours. I request further diagnosis and repairs. Despite the vehicle continuing to show symptoms, I was dismissed. I am seeking accountability and proper resolution.

1.) We were driving to Nashville and once my car got around 70,000 mile my check engine light came on. Then my car started to make a humming noise. We pulled over to check the oil the oil was fine. Once we got back into the car and left the gas station the light started to blink. Yes 2.) We were on the highway, and if the engine could have blown up or we could've got stuck on the way there and back. Also, the where the car started to act up was around a bad neighborhood. 3.) Yes 4.) Yes 5.) The car started to hum but once my car hit 70,000 miles the check engine light came on and started to flash.

The vehicle experiences a complete loss of power when slowing to a stop before it powers off on its own. The car powers off while going down the road. The car experiences partial loss of power while on cruise control and the car will slow to nearly stopped. The immediate loss of power puts myself and others at risk as the car is now stopping unexpected on the highway. I have left numerous voicemails for service managers at the dealership it was purchased brand-new from 2 years ago. They have not reached out to me. I had an appointment at their dealership to have the car inspected to see if this was covered with my warranty and they explained my warranty was only 60k miles and my car is now at 65k miles. The car was shutting off and having power loss a week before the first indicator light came on, which was the engine light. The code pulled for that sensor was the P0171 sensor which measures air in the fuel system and it stated "bank 1 running lean". I have now taken the car to a local shop and they are advising there was no oil in the car and there are metal shards in the valves in the engine. Werner KIA is the only shop that has ever worked on my car or changed the oil and they have not advised me of any oil leaks at all.

In April 2023 I purchased a 2021 Kia Soul. I had no issues at all with my Used Kia Soul. In Nov 2023 I was in an accident. I hit a deer and that did cause damage. My insurance company fixed it. I got my car back in Dec [XX], 2023 with approximately 96,000 miles on it. A few days later on my way to work. I entered the highway the car was running fine at 70mph then all of a sudden it lost power.. No power in the middle of the busy Atlanta Highway!! I was able to coast onto the shoulder. At that point I turned the car off. Turn the car back on to see if I was able to get it into Drive. Unfortunately that didn’t work my car didn’t move at all. I had to call the tow company get it towed back down to the collision shop. Only for the collision shop to send it to a Kia dealership. My car had been at the dealership for a few weeks. Today is February 8. I got the notice from my insurance company that the Kia dealership said I had metal shavings inside of my transmission and fluid. How does that happen? Then I decided to do some research and I noticed that this transmission is a problem. Not only a problem for people that are struggling with bills and finance charges but a problem with the manufacturing of this product. I’m not sure why there isn’t a recall on this transmission, if I was unable to get off of the highway I would have been hit. What is being done about this problem? To add injury to insult my 100,000 mile warranty isn’t any good because I’m the second owner of the car. I don’t understand how this isn’t a safety recall issue.

We were traveling on the freeway 70 mph surrounded by heavy traffic at night, the vehicle started surging and bucking, shaking violently. The rpm's swung wildly from 2000 to above 3500 and car started to decelerate quickly in heavy traffic. I was able to get the car into right lane but feared being rear ended due to speed falling abruptly. Even though accelerator was being depressed and engine running car would not go and loosing power fast. I was able to turn off at an exit and there was just enough enough power to make it up a slight hill and turn right onto a round-a-bout where the vehicle would no longer move, abruptly stopping the fast traffic behind and again fearing a rear end collision to us. The engine produced power but nothing going to wheels, it was as if vehicle was in neutral no matter where the shift selector was placed. The police helped to push us off the road into a parking lot.

I was on the freeway, and the car was shuddering a bit before I lost the ability to accelerate. It would rev but no power to the wheels. Had to pull over and get towed to the dealer. I think it may be a transmission failure.

I bought my 2021 Kia Soul on 10/21/20. Then on 11/11/20 my car started having transmission issues within less than one month of ownership & nearly 1000 miles on it. The transmission was replaced in late Nov./early Dec. of 2020. On 12/15/22, My Soul started revving up & the RPM needle was bouncing while driving, but the car would not go any faster when I pressed the gas pedal. I realized, I was having transmission issues with my 2021 Kia Soul, AGAIN. The car has less than 37,500 miles on it. I contacted Power Kia of Salem Oregon that day & the first appointment that I could get was on 12/29/22. I had the car towed to Power Kia on 12/27/22, then received a voicemail & text msg. from Power Kia on 12/28/22 that they will diagnose the issue. That was the last time that I got any information about my car without me contacting them. It has been OVER THREE MONTHS & Power Kia STILL has my vehicle & has not bothered to contact me with updates unless initiated by me. They have not provided any assistance for transpiration during this difficulty, even though that I told them multiple times, that I commute 80 miles daily. I bought a brand-new car to have reliable transportation to & from work, only to have to replace the transmission TWICE & be without my vehicle for nearly four months. The complete disregard of my safety by Power Kia when driving a car with a faulty transmission is reprehensible. I have developed anxiety issues, have had sleepless nights, and now have panic attacks just at the thought of dealing with this matter.

I own a 2021 Kia Soul with 34,130 miles. Purchase brand new in 5/21. I just had it serviced on 2/3/23. On 2/10/23, I was driving toward home on I-40 east, near mile marker 418 and the rpms suddenly started to jump up and down from 1000x to 6000x and the car had no ability to go anywhere close to the speed limit. There was a whistle noise coming from under the car. I took the I-81 north interchange to try to get the 80 or so miles back home but could not get the vehicle to go more than 15 mph. I was terrified I was going to get hit by the 18 wheelers whizzing by me. I got in the break down lane and limped to exit 8. The car began to shake violently and barely move. I got off the exit ramp praying no one would rear end me. I called Kia roadside and they towed it to the closest dealership in Moristown because they only tow up to 50 miles, unless I paid the requested $300+ to take it the extra 30 miles to my dealership where I bought the car. The service department called on 2/11/23 to tell me it was being evaluated now, but I have heard nothing else since. I had to sit at the dealership in Moristown until my sister could drive from Lexington KY to take me home. I have severe walking impediment due to broken neck from a car wreck. This whole experience was terrifying.

The engine is consuming increasingly high amounts of oil with no leaks, far surpassing the one quart per 1000 miles. Oil pressure lamp has illuminated on 1-2 occasions, only briefly, and shortly before I took it to the dealership. Unusual noises coming from the engine while accelerating and also after I stop. I had my oil changed 1 week ago, unusual noises have not improved. Currently awaiting inspection at the dealership for manufacturer warranty coverage for repair of this issue, but seems to have all the earmarks and the production date (9/20) that line up with the piston ring recall, though they say my vehicle is not covered by the recall.

The vehicle started loosing power. the engine would rev up but the car wouldn't go. the car had to be towed to the dealership because the vehicle would not engage into drive or reverse. the dealership is replacing the transmission. It is the IVT transmission

I I WAS ON THE INTERSTATE AND MY CAR STARTED MAKING A LOUD NOISE AND DECELERATED. IT SEEMED TO LOSE POWER, I TURNED AROUND AND STARTED HOME AS I WAS VERY FRIGHTENED. THE CAR ACCELERATED WITHOUT PRESSING THE GAS, DECELERATED WITHOUT PRESSING THE BRAKE. THE TACHOMETER WAS SWINGING AROUND WILDLY. THE CAR MOST OF THE TIME SEEMED TO HAVE NO POWER. I WAS AFRAID OF A REAR END HIT BY ANOTHER CAR OR FLYLING INTO THE BACK OF THE CAR IN FRONT. I WAS TRYING TO LIMP IT IN TO THE DEALER. THE CAR ONLY HAD 3400 MILES ON IT AND I HAD HAD IT FOR 7 MONTHS. AT ONE POINT I HAD TO STOP FOR A RED LIGHT AND THE CAR WOULD NOT MOVE. I PUT ON THE WARNING FLASHERS AND TIRED TO EDGE TO THE SIDE OF THE STREET AS THERE WAS A BIT OF SLOPE. I TURNED THE CAR OFF AND RESTARTED IT AND WAS ABLE TO GET IT TO THE DEALER ABOUT 2 MILES AWAY WITH VERY LITTLE POWER. THEY TOLD ME IT HAS TO HAVE A NEW TRANSMISSION. THEY SAID THEY ARE REPLACING THE TRANSMISSION WITH A DIFFERENT KIND AND IT WILL BE SAFE NOT TO WORRY, THOUGH CONFIDENCE IN THE VEHICLE IS DIMINISHED. I UNDERSTAND THAT THE IVT TRANSMISSION THAT KIA DEVELOPED IN 2020 HAS BEEN GIVING PROBLEMS.

VEHICLE WAS PARKED ON A SLIGHT SLOPE PARKING SPACE BACKING TO A ONE-WAY PUBLIC ROAD IN NATIONAL PARK.IT WAS A DESIGNATED PARKING SPACE. THE VEHICLE WAS RUNNING AND IN THE P MODE OF GEAR SELECTION. I EXITED THE DRIVER'S DOOR FOR FEW MINUTES. THEN OPENED THE DRIVER'S SIDE DOOR WITH THE INTENT TO SHUT THE ENGINE. THE CAR STARTED ROLLING BACK, CROSSED THE ROAD, AND STOPPED BY A SANDY EMBANKMENT. I WAS THROWN OFF BY THE OPEN DOOR ON THE SANDY BANK. THE ENGINE STOPPED AND I OBSERVED THE VEHICLE IN D MODE BY ITSELF. I WAS ABLE TO START THE CAR IN THE P MODE AND WAS PULLED OUT WITH HELP OF SEVERAL PEOPLE WHO OBSERVED THIS NEAR-MISS SERIOUS ACCIDENT. THIS WAS A RENTAL CAR. NO FURTHER PROBLEMS OBSERVED. CAR RETURNED TO THE RENTAL COMPANY.
