2018 Hyundai Tucson Transmission Problems

The engine and engine management system of my 2018 Hyundai Tucson experienced repeated failures resulting in loss of propulsion and unsafe drivability. In November 2025, while traveling approximately 75 MPH on a freeway, the vehicle suddenly entered limp mode without any prior warning, causing an abrupt loss of power in active highway traffic.

I was driving on the highway, about to change lanes, when I looked in my rear view mirror and saw black smoke coming from my appeared to be my exhaust. I immediately started to pull over, and that is when the oil light first appeared on my dashboard. By the time I had put the car in park, the check engine light had also appeared.

On April 12, 2025, my 2018 Hyundai Tuson which only has 99,000 miles started stalling out at random speeds. The vehicle stalled going up a hill and would not accelerate it would also not go past 55-60 miles per hour on the highway. There were no check engine lights or codes on the dashboard.

car would not speed up no matter how hard I pressed accelerator, vehicle wouldn't speed up kept going at slower speed had to have towed to dealership. don't know what is wrong. I was scared someone would hit me, or my speed would cause an accident.

I was driving home from a family get together with my husband and daughter in my car. We smelled something burning, and suddenly smoke was coming out of my center console. I pulled over and flames were coming out of the driver side.

The engine has failed in my 2018 Hyundai Tuscon. I was driving the car daily since purchasing in July of 2023. Everything was fine until the first week of October, I had just picked up my son and was getting on the interstate when my check engine light came on and my oil light would flash on and off occasionally not persistently.

As I was pulling out of a bank driveway onto a busy access road my car just died. Lost all power. NO warning bells, no lights on the dash, no warning at all.

Immediately after purchasing the car I stopped for gas. When pulling out of the parking lot and onto the road, the transmission stalled. The car did not move, the rpms jumped to 5-6 and the lurched and jerked forward then stopped and lurched forward again with the rpms jumping high.

The car has acceleration issues and when you try to press down on the gas it sputters and loses power, it is becoming a safety hazard when driving 45 MPH or higher. If you try to pass another vehicle it slows down and almost stops, we have had to pull to the side of the road to avoid being in an accident.

my 2018 Hyundai Tucson starting having lurching issues on when first started. I have to back into my driveway so I dont have to go in reverse then go forward. it jerks back and forth so hard.

About 6 months of owning this vehicle, I started noticing while sitting in traffic that when letting off of the brake the car would start to jerk as you gave it a little throttle. I took the car to the Hyundai in Glendora where I purchased the vehicle from and they stated that there was nothing wrong with it.

Car was slowly entering garage and came to a full stop with brake pedal depressed in gear. Car without warning, engine revved up to full power and crashed in garage. I am alleging condition known as sudden unintended acceleration.

VEHICLE CAUGHT FIRE WHILE DRIVING ON THE HIGHWAY.

I purchased my 2018 hyundai tucson limited 1.6l forward drive new in november 2018. I started experiencing problems a few weeks after my purchase. The vehicle is slow to accelerate at times and other times the vehicle lurches/accelerates forward at a high rate of speed with my foot on the brake pedal.

, from a stop, when you move forward, you press on the accelerator the car hesitates to move forward then all of the sudden if reves high and then speed faster than it should, I have called the dealership two times, the vehicle has 11,000 miles on it and has never been in an accident. Something with the dual-clutch system is having issues and will lead to death.

I have the 2018 tuscon limited 1.6t dct with no more than 12,000 miles. When accelerating from a stop or accelerating after braking and pressing the gas pedal normally, the car stops accelerating and the car slows down. This also happens after coming to a stop and turning onto a different street.

Hyundai Tucson has been jerking and shaking for over over 4 years now and either when taking to the dealership they reset the dual clutch and have replaced the same part twice in the dual clutch. This shaking has been happening since the car was bought brand new like a year after. The vehicle now will get stuck in gear and while driving will go down to 20 MPH and get stuck in that speed.

My 2018 Hyundai Tucson 2.0L GDI engine with only 79,000 miles was "knocking" and wouldn't accelerate. We pulled over and towed the vehicle to the local Hyundai Dealer who declared "oil level good but failed bearing clearance test". Diagnosed with a rod and bearing failure.

In late September of ‘24 my husband was driving our oldest to school when my 2018 Hyundai tuscon seized mid drive with our son in the back seat with no oil or engine light warning. Husband inspected the oil and I was still full. A Hyundai dealer towed at their expense in October, diagnosed an engine failure.

Me my wife and our dogs were driving from California to Las Vegas when we experience loss of power in the engine we managed to Coast downhill to State Line Nevada and got to the off ramp and then had to push the car to the nearest gas station it was towed the next day to Centennial Hyundai in Las Vegas, case # [XXX] this happened while on vacation just before Christmas they were not able to look at it till after Christmas but they found that one of the valves had broken and was sitting on top of the piston we were told that the engine the turbo the exhaust and the catalytic would all have to be replaced also later they discovered a leak in the transmission on the Dual clutch which also needed replacing we were just told that they have finished the work and we would be responsible for about $5,300 worth of the work I have all maintenance records on this vehicle it had all scheduled maintenance done at the dealership including oil changes and any other repairs that or needed including engine cleaning once the car reached about 100,000 MI it started consuming about a quart of oil every oil change I'm [XXX] old and have had many new and used cars and have never ever had an engine failure happen at such a low mileage when this occurred the car had approximately 122,000 miles on it I have a claim with Hyundai customer care, case # [XXX] and they have not been very cooperative they don't seem to be able to contact the dealership to get any kind of resolution for the costs that I don't feel are my responsibility this is unbelievable I will never recommend anybody by a Hyundai or a Kia I will tell them buy a Honda or a Toyota not a Hyundai or a Kia they have horrible engines and Transmissions it should not be failing at less than 100,000 miles or before the car is even paid off unbelievable don't know how we're going to cover the cost the dealership wants to get our car back I guess they'll just have to keep it for a while.

End of April/beginning of may, driving down highway check engine light flashing loud knocking and loss of power. Got it towed by AAA. Wasnt able to make appt until May 9th.

issues with the 2018 Tucson- Transmission has always sputtered, had numerous updates and resets for it. still an issue. also it doesn't want to go into gear sometimes and bob when going into drive, or reverse.

Back in January of 2023, car would not go into reverse. While out driving the engine light came on and went into safety mode. I had no power to merge onto highway and make it up hills to get to Hyundai service repair.

While driving the vehicle, while accelerating the vehicle would lose power or disengage from gas pedal at 17 MPH and then again at 26 MPH. After about 3 miles the check engine light came on and a TCM warning appeared on the radio screen. Immediately took the car to the dealership and was turned away since I didn’t have an appointment.

Car has no power when accelerating, when accelerating from a stop the car revs but does not move, then when it does move it takes off like a rocket, in slow moving traffic 5 MPH, you accelerate and the car seems like it wants to stall, a lot of hesitation, In fast moving traffic, if you want to merge or pass another vehicle you must give yourself ample time and make sure it is clear to make your move, if you need to get out of the way really fast you cant, its very dangerous and Hyundai needs to move quick on this before something really bad happens to someone.

Rod bearing failure. Sounded like a tractor all of a sudden and stalled every time I’d come to a stop. Had it towed to the dealership.

The vehicle almost stalls and doesn't want to take off 1st thing in the morning then suddenly it accelerates abruptly well above the amount of pedal pushed. It also has inconsistent shifts at anytime during a drive. Sometimes it won't shift until we leave off the gas.

My 2018 Hyundai Tuscon has been having major issues with the dual clutch transmission, which has put myself, my family, and others in very dangerous situations. Everyday when I start my Tuscon and accelerate, it stutters/jerks like it’s going to stall and will not accelerate/shift.

Vehicle has judder at slow speeds or hesitation in shifting gears. Has almost stalled while making a left turn at intersection into oncoming traffic or accelerating after stop sign . Dealer updated TCU ECM software, problem got worse.

Car constantly hesitates when starting to accelerate. When you begin to accelerate from a stop, the car hesitates for several seconds before beginning to move. This is very dangerous when making turns at stop lights or in intersections.

Mostly in the morning after the vehicle has sat all night and occasionally throughout the day after stopping at red lights or when leaving a parking lot. The vehicle will 'stall, shutter' or however else you want to describe a rapid jerking motion while trying to accelerate from a stop. It causes a delay in the ability to effectively and safely merge the vehicle into traffic at times.

My specific Tucson is equipped with 1.6L Turbo and a 7 speed Dual-Clutch Transmission. I see there are recalls for the 2016 models equipped with the same transmissions, so I'm concerned as to why there hasn't been a recall for the newer models.

My car on the expressway wouldn't go over 40 and this was happening intermittently so my car was unsafe. No check engine light but it was just at the dealership for an oil change. been an ongoing problem since I bought the car!

Over the past nine months, I’ve been experiencing ongoing issues with my 2018 Hyundai Tucson engine and transmission. After four consumption tests and a flush confirming that the engine is burning between 0.8 and 0.3 liters of oil for every 1,000, I was informed Hyundai refuses to either repair the issue or conduct testing to determine the cause.

29 days after I bought a 2018 Hyundai Tucson. The vehicle started making a ticking noise and stopped accelerating. I called the dealership and they said we didn't get a warranty.

While starting and accelerating my 2018 Hyundai Tucson, I began hearing abnormal engine knocking and noticed rough performance. I took the vehicle to an authorized Hyundai dealership, where they diagnosed an internal engine defect.

The contact owns a 2018 Hyundai Tucson. The contact stated that the vehicle was consuming an excessive amount of engine oil with the oil warning light illuminated. The vehicle was taken to an independent mechanic and a dealer to be inspected and two oil consumption tests were performed by the dealer.

In May 2024 my Hyundai Tucson died in a middle of an intersection with no warning. Worse than that is Hyundai motor USA informed me that the car was on a recall list for an engine failure issue that was apart of class action suit . Ans further told me that that were obligated to have the highway transportation safety dept notified first consider cause of the issue.

ABS SENSOR, downhill light, traction control light stays on. In August 2023 the transmission had to be rebuilt from slipping. After work there is still transmission slipping.

While on the highway going 70mph the check engine light flashed on the immediately off out of nowhere and car started aggressively shaking before loosing temporary power. My wife and toddler were in the car and we were all pretty shaken up. Luckily I was able to gain control of the car but I'm concerned that another issue may occur.

It started [XXX] when I took my car to the dealership due to it going into limp mode. The dealership took it in and said it was throwing error code p1326 which is the knock sensor code. they replaced the knock sensor, drove my tucson home after the replacement, by the time I got home it went into limp mode again, took my car back to the dealership turns out it was a faulty sensor they received.

Check engine light stayed on vehicle transmission unable to shift in reverse and lower power when car is driven in a low speed.

CVT Transmission failed under 70,000 miles. The vehicle is available for inspection upon request. My safety was put at risk due to no warning light or indication of this failure from Dick Smith Hyundai in Greenville, SC during a routine maintenance check.

When I accelerate from a stop sign or yield it Jerks and hesitates to accelerate. I have to release the gas and push again sometimes doing this multiple times when this happens daily. I've taken it to Hyundi shops and they say it's a normal chararistic if a Tuscan.

Transmission is jerking when driving. Brakes are squeaking.

This very low mileage vehicle recently had the same incident for I believe the fifth time since I've owned the car. In a very dangerous situation the car exibited the car going almost dead after normal acceleration. It regains power after 3-5 seconds and rapidly returning to acceleration.

Tucson 2.0L hesitation at acceleration particularly from a rolling stop: This intermittent problem was checked initially by Marhofer Hyundai in Cuyahoga Falls Ohio, their findings were negative. We then took it to Great Lakes Hyundai in Streetsboro and they said they were aware of the problem and reset the computer, but it did not resolve the problem. This problem has put my family in harm's way many times, making a turn from a rolling stop the car lags into ongoing traffic. Our last visit to dealership we were told car was out of warranty 19,000 miles but the problem was never fixed. This vehicle was a certified pre-owned and have an extended warranty. I have attached a technical service bulletin.

i received a letter in the mail stating the nock sensor has been replaced i dont know howlong ago but my 2018 tucan is stuck in false sage mode saying the nock senor was bad! if it is a on going issue and there is has been a recall on the part why does it show no recalls for my mode car?

I have only owned the car for 1 month. I had gotten an oil/filter change and a new oil pressure sensor at ~80,100 miles. I had requested the oil sensor be changed because it would flicker on and off when the car was idling/low RPMs once it had heated up fully. This had fixed that issue seemingly. At ~80,700 miles the car had started riding a bit "rough", especially at higher speeds, so I decided to have a look under the hood. I was terrified to see that my dipstick was bone dry. There was never any evidence of any noticeable leak underneath the car on the driveway nor any evidence of blue smoke coming out of the exhaust. After some research (Hyundai corporate was telling me over the phone multiple times that there was no known issues with my specific car/engine) I was appalled to see I was essentially lied to. I found multiple official TSBs, NHTSA notices, and hundreds if not thousands of other customers noting the exact same experience. I had tried to take it to Hyundai for the oil consumption tests laid out in multiple TSBs but I was denied "due to the original warranty expiring". To my knowledge this exact issue has caused Hyundai and Kia to extend to 150k miles for all owners. This is my only mode of transportation and I am so worried my car will stall/seize/catch fire on the highway. This is beyond unsafe and unacceptable but I assume I may have to wait until the final litigation hearing in September for official recalls to be issued. If my car makes it that long.

Purchaseing the vehicle two months ago, the engine service light started blinking. Taking the vehicle to several shops including two hyundai dealers, I was informed the vehicle had an off market catalytic converter. I asked the dealership several times if there was any issues with the vehicle and they stated there was not. The engine first came on two weeks after the purchase of the vehicle. It is not safe to drive.The warranty nor the dealership will cover or assist.

Acceleration issue, from a stop position on a red light or stop sign, when the gas pedal is pressed the engine revs but does not move immediately, after a couple of seconds it lundges forward, also when trying to merge you must wait for a very big gap to safely merge, the car does not respond and this is very dangerous, Hyundai need to rectify this issue before someone dies.

When driving at night and low-beams are on, there is a black void (looks like a black bar horizontally across the headlight projected area on roadway). Black void is eye level with driver’s view of the roadway. With the black void present, driver is unable to see the roadway clearly at night, which inhibits the drivers visibility and ability to see road hazards or animals crossing the road. Low-beam and high-beam bulbs have been replaced and checked for any burn spots or malfunction in the bulb itself; with brand new bulbs installed professionally, the black void is still present. Hyundai repair stated it is a known issue that has yet to be addressed by Hyundai Manufacturers. Issue has been present for 2-months now. While driving on interstate, went to pass a vehicle and while accelerating the vehicle would not increase in speed. The RPM needle jumped to 5-6 and a “whiny” noise was coming from engine area. Pressed harder on the accelerator so the car would speed up and with the pedal to the floor, the vehicle speed increased 1 mph in 5-sec intervals. Exited the interstate and was traveling on road with 60mph speed limit. Tried to accelerate again, and the vehicle would make the whiny noise and would not increase speed or shift. Let off of the accelerator and the RPM drops instantly to 2-3. RPM’s need does not smoothly increase or decrease, but instead jumps or drops instantly. When accelerator is pressed or when trying to increase speed, the whiny noise comes from engine. The vehicle sounds and acts like it is not shifting. Took to dealership and they said there are no recalls on transmission, but will not fix my transmission. 10-year/100000 mile warranty is still active, as it is a 2018 w/ 89500 miles. Safety concern as the vehicle will not accelerate or shift when needed and could cause serious accident if in a situation where evasive action is required.

Leaving a parking lot, vehicle was hard-shifting at 10mph, 20mph, 30mph and was not gaining typical acceleration. Every slow down or stop sign/stop light this behavior continued with automatic hard shifting between gears and lethargic acceleration to the point where I felt this may cause an accident or cause another vehicle to have an accident due to lag response of my vehicle. Upon home arrival, I attempted to back vehicle into my parking spot but after shifting into Reverse, the R indicator on console was flashing but vehicle would not move. I drove back around the complex parking circle and again attempted to back vehicle in to a different parking space but experienced the same issue where R indicator was flashing but vehicle would not back up. My daughter and 2 grandsons then had to push my vehicle back in to the parking spot. I turned vehicle off, waited approximately 90 seconds and restarted the engine. When I shifted into Reverse gear, the car abruptly and harshly shut down. At that point, I put the vehicle back into Park gear and turned off ignition. Had the vehicle towed to closest dealership on Nov 28th - they have not been able to replicate issue nor find any fault codes when running diagnostics. No dashboard errors appeared, only the flashing Reverse indicator light on shift console. No prior issues earlier in the day when using vehicle, nor has this issue occurred in the 4 years I have owned it. It was severe enough I wasn't sure the vehicle would clear intersections in a timely manner, and worried it may leave myself and my daughter and grandsons stranded on the 20 minute ride to home.

Vehicle stalls when accelerating at low speeds. It appears to be a delay when the car transitions from 1st to 2nd gear. This creates a safety concern, especially when taking turns into traffic due to delays/stalls when turning.

I’ve been having an issue with the car “jerking rapidly” when in traffic and rolling slowly and when climbing relatively small hills, it began about 2 months ago but have become progressively worse over the last month. I was told by someone with a similar vehicle that it is the “lower arm control. Need help with is or if there is a recall

While driving my car normally 9 dashboard lights came on suddenly including the check engine, ABS, brakes while at the same time the dials on the dashboard including the rpms, speedometer, oil temperature and more all stopped working. This happened suddenly while the car was in drive and also caused issues with the transmission as the car stopped shifting gears properly and was driving very rough. With this sudden onset of many different issues out of nowhere driving the vehicle was very dangerous when trying to get to a safe location. After parking this electrical issue would not allow me to take the car out of park or use a OBD reader do to the electrical issue. After researching this problem I found several reports online describing nearly identical symptoms all of the sudden resulting in the car being undrivable and in a dangerous state. These owners said they took the cars to the dealer who tried replacing several components without fixing the issue with hours of diagnosis charges. Eventually after having the vehicles for several days they replaced the reverse camera which it turns out was shorting a significant amount of other critical car electrical components. With no prior damage to the camera or these electrical components the abrupt and random onset of this issue pose a significant safety risk to Hyundai Tucson drivers (at least in 2016 -2018 models) . My experience with the Hyundai Dealership was very similar to them even after I had diagnosed the issue to the camera the dealer said they had contacted the manufacturing engineers who took several days to determine what was causing these electrical issues. This is not an isolated issue as multiple hyundai tucson owners have reported this to Hyundai and their dealerships yet they fail to recognize the risks associated with the faulty cameras they install in their factories. They need to recall their vehicles prone to having this issue. This has cost me $1000 to fix and put me at risk on the road

Powertrain issue. Multiple times the after stopping the engine revs for a few seconds and then the vehicle will lurch forward. It acts like the CVT transmission has a delayed response to the accelerator.

very bad acceleration from a stop position, engine revs but does not move, in slow traffic it hesitates and lunges forward like it’s not sure what it’s suppose to do, when trying to merge or pass another car, you have to give yourself time, it’s very dangerous, took it to the dealer 2 times, was told that’s how the car is made, there is no way this is suppose to be the way the car was built.

When merging into traffic, the car lost all acceleration and the transmission revved to a very high RPM. This has been an ongoing problem since the car was purchased. The dealer keeps saying they “cannot replicate”.

Hyundai has historically had an issue with the dual-clutch transmission and the vehicle is available for inspection upon request. The vehicle frequently shutters / shakes at a stop and when accelerating from a stop. Additionally, the vehicle occasionally loses power to the wheels when driving-up a moderately steep grade.

Car not shifting properly. Took to dealership and kept getting a response of the car have a dual clutch.

The contact owns a 2018 Hyundai Tucson. The contact stated while at a complete stop, the vehicle hesitated while depressing the accelerator pedal. There was no warning light illuminated.

Warning light on dashboard board goes on and off constantly indicating rear brake light needs attention. When warning light is on, brake light does not work. When warning light turns off, brake light works.

Transmission fails to shift properly. Had this issue since around 15k miles purchased vehicle brand new and complained multiple times dealer wouldn't do anything until around 55k miles replaced dual clutch and problem had come back after 5k miles and dealer says nothings wrong... I feel unsafe in a brand new car with regular maintenance...

I WAS DRIVING ON A INTERSTATE GOT OFF ON A EXIT AND MY CAR STARTED DOING A LOUD TICKING NOISE AND WOULD NOT ACCELERATE OVER 40 MPH. I DROVE THE CAR TO GET THE CAR TESTED TO SEE THE PROBLEM .THE CODE READ KNOCK SENSOR.GOT THE KNOCK SENSOR REPLACED BY A LOCAL MECHANIC AND THE CAR DROVE THE SAY WAY BEFORE I TOOK IT TO HIS SHOP.THE CAR ONLY HAS 67,00 MILES

The transmission severely lags in the initial transition into first gear, as well as from first to second. When initially engaging into first gear from reverse, the car rumbles and chops into first gear. Although this is a dual clutch car, it severely lags into acceleration, causing a major safety hazard, especially on the freeway.

HAS DEVELOPED INTTERMINTANT SHIFT STUTTER WHILE DRIVING (CITY AND HIGHTWAY) AND DEALYED POWER FROM A STOP (NO GO SYNDROME). THE PROBLEM ISGETTING WORSE AND THE HYUNDAI HASN'T BEEN ABLE TO FIX IT.

Bought the vehicle new. The problem originally began as intermittent now occurring almost constantly. If vehicle is in a stopped position upon pressing the accelerator the vehicle does not move forward for up to one to 2 seconds.

The dual clutch, 7 speed automatic transmission in my 2018 hyundai tucson does not always move the car. When pulling out of a driveway, intersection, or crossing oncoming traffic lanes the car will stop moving while partially in the street/intersection. It will not move, the engine RPM's rev up and then all of a sudden the car lunges forward.

WHEN I WENT TO ACCELERATE OUT OF A BUSINESS DRIVE WAY, THE CAR HESITATED AT LEAST 1-3 SECONDS BEFORE ENGAGNG THE TRANSIMISSION TO ACCLERATE THE VEHICLE OUT OF THE DRIVEWAY INTO TRAFFIC. AS I WAS TURNING OUT OF THE DRIVEWAY, I WAS ALMOST STRUCK BY AN ONCOMING VEHICLE. I WAS IN 2 OTHER SEPARATE INCIDENTS EITHER ACCCLERATING TO GET INTO A LANE OR ACCELERATING FROM A STOPPED POSITION ALMOST CAUSING ACCIDENTS BECAUSE OF THIS PROBLEM. I WAS SO SCARED, I TRADED THE 2017 TUSCON IN FOR A 2018 TUSCON HOPING THE PROBLEM WOULD BE SOLVED. IT DID NOT. IT HAPPENS IN THE 2018 TUSCON LESS OFTEN, BUT MORE INTERMITTENTLY MAKING IT EVEN MORE DANGEROUS AS YOU DO NOT KNOW WHEN OR IF ITS GOING TO HAPPEN AND BE ABLE TO REACT APPROPRIATELY.

SAME DUAL CLUTCH PROBLEM AS ON 2016 HYUNDAI TUCSON. HESITATES FOR SEVERAL SECONDS PRIOR TO ENGAGING WHICH CAUSES SIGNIFICANT DANGER IN ONCOMING TRAFFIC. I HAD THIS SAME PROBLEM WITH THE 2016 AND HYUNDAI CONTINUED TO DENY ANY KNOWN PROBLEMS. NOW THERE IS A CLASS ACTION LAWSUIT REGARDING THIS ISSUE. I TRADED MY 2016 IN FOR THE 2018 TO GET AWAY FROM THE PROBLEM BECAUSE I WAS SO SCARED. NOW I HAVE THE SAME PROBLEM WITH THE NEW CAR. THIS PROBLEM IS ONGOING. ALSO I WAS COASTING WITH FOOT NOT ON THE PEDAL AND NOT IN CRUISE CONTROL AND THE RPM'S SHOT UP TO 4200 THEN DOWN TO NORMAL, THEN BACK UP TO 2200 AND THEN BACK TO NORMAL. VERY SCARY. HAD CLUTCH ENGAGED CAR WOULD HAVE SHOT FORWARD INTO CAR IN FRONT OF ME. DEALER HAS ACKNOWLEDGED TROUBLE WITH BOTH PROBLEMS AND INFORMED ME THAT HYUNDAI HAS SWITCHED CLUTCH MANUFACTURERS.

THIS IS MY 2ND ISSUE WITH THIS VEHICLE. EVER SINCE I BOUGHT THE VEHICLE I HAVE ALWAYS NOTICED THAT WHEN I COME TO A COMPLETE STOP (AT A RED LIGHT OR STOP SIGN) AND I GO TO PRESS ON THE GAS THE CAR DOESN'T GO. IT'S LIKE IT HESITATED BEFORE IT STARTS TO PICK UP SPEED. I ALWAYS CHALKED IT UP TO THE FACT THAT IT WAS A 4 CYLINDER BUT AFTER SPEAKING TO MY MECHANIC I FIND OUT THAT THIS IS NOT NORMAL AND CAN BE THE SIGN OF A SERIOUS PROBLEM. THERE IS CURRENTLY NO FIX FOR THIS.

WHEN SHIFTING GEARS, IE P TO R OR R TO D OR P TO D, THE CAR JERKS / CATCHES. SOME HAVE CALLED IT "TURBO LAG". IT'S DEFINITELY MOST NOTICEABLE AT A DEAD STOP. I HAVE EXPERIENCED THIS "LAG" WHILE BACKING UP OUT OF A PARKING SPOT AND THEN TRASFERRING TO DRIVE, AS WELL AS BEING AT A DEAD STOP AT A STOP SIGN / RED LIGHT, AND THEN ACCELERATING. BOTH EXPERIENCES HAVE BEEN IN THE CITY, HIGHWAY, TURNING, AND LOCAL ROADS. I DON'T KNOW WHAT HAS CAUSED OR WHAT IS CAUSING THIS ISSUE. PERHAPS IT'S THE TORQUE CONVERTER? I BOUGHT THIS CAR NEW IN NOV 2018 AND HAVE HAD THIS ISSUE SINCE JAN 2019. I HAVE HAD OTHER PEOPLE DRIVE MY CAR AND THEY HAVE ALSO EXPERIENCED THIS ISSUE. OTHER HYUNDAI TUSCON DRIVERS HAVE ALSO EXPERIENCED THIS ISSUE, AND HAVE DISCUSSED IT AT THIS WEBSITE: HTTPS://WWW.CARCOMPLAINTS.COM/HYUNDAI/TUCSON/2018/TRANSMISSION/WILL_NOT_ACCELERATE.SHTML

THE 2018 HYUNDAI TUCSON SEL HAS AN INTERMITTENT ISSUE WHEN ACCELERATING FROM A STOPPED POSITION. THE ENGINE WILL REV UP, BUT IDLE FORWARD FOR ABOUT 3-5 SECONDS, UNTIL THE VEHICLE GOES. THIS DOES NOT HAPPEN CONSISTENTLY. THE DEALERSHIP HAS RESET THE PROGRAMMING ON THE TRANSMISSION 2X. THERE ARE OTHER INDIVIDUALS ONLINE THAT ARE EXPERIENCING SIMILAR INTERMITTENT ISSUES WITH THEIR 2018 HYUNDAI TUCSON. IN JUNE 2019, I WAS ALMOST STRUCK BY A VEHICLE WHILE I WAS COMPLETING A LEFT HAND TURN ON GREEN WHEN AN ONCOMING VEHICLE DECIDED TO RUN THE LIGHT. THIS HAS HAPPENED NUMEROUS TIMES. ON 10/7/19 - I BROUGHT IT BACK TO THE DEALERSHIP AGAIN TO RIDE WITH A TECHNICIAN. DURING THE 30 MINUTES RIDE, I FELT LIKE I HAD REPLICATED THE ISSUE SLIGHTLY BUT THE MECHANIC ONLY ASKED ME WHAT KIND OF CAR I PREVIOUSLY DROVE. WHEN I CHECKED OUT OF THE DEALERSHIP, I ASKED FOR PAPERWORK TO DOCUMENT MY ENCOUNTER, EVEN IF THE MECHANIC CLAIMED IT WAS UNFOUNDED - BUT WAS NOT PROVIDED WITH ANY AND TOLD THAT THERE WAS NOTHING TO DOCUMENT.

TL* THE CONTACT OWNS A 2018 HYUNDAI TUCSON. WHILE STOPPED AT A TRAFFIC LIGHT AND ATTEMPTING TO AVERT BEING STRUCK IN THE REAR BY ANOTHER VEHICLE, THE CONTACT DEPRESSED THE ACCELERATOR PEDAL, BUT THE VEHICLE HESITATED TO RESPOND. AFTER SEVERAL SECONDS, THE VEHICLE RESPONDED. THE VEHICLE WAS TAKEN TO MIKE KELLY HYUNDAI (254 PITTSBURGH RD, SUITE B, BUTLER, PA 16002, (724) 287-2701) ON SEVERAL OCCASIONS WHERE IT WAS DIAGNOSED THAT THE DCT TRANSMISSION OPERATED AS INTENDED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED ON SEVERAL OCCASIONS AND INFORMED OF THE FAILURES. THE MANUFACTURER PROVIDED CASE NUMBERS 12236015, 15808024, AND 16248911. THE APPROXIMATE FAILURE MILEAGE WAS 5,000.

BOUGHT NEW. VEHICLE HAS ACCELERATION ISSUES. RPMS SKYROCKET. IF ON DOWNWARD SLOPE, CAR WILL ROLL INTO INTERSECTION UPON DEPRESSING PEDAL. ON UPWARD HILL, CAR WILL HESITATE, THEN SUDDENLY JERK AND TAKE OFF. I HAVE A ROLLED INTO AN INTERSECTION TRYING TO CROSS A 2-LANE ROADWAY AND THE CAR STOPPED. I HAVE MENTIONED TO DEALERSHIP AND THEY JUST SAY IT'S THE WAY THE DUAL CLUTCH WORKS. THE DEALERSHIP HAS DONE A FACTORY RESET. I WILL BE GOOD FOR ABOUT A DAY. STILL NO ACCELERATION WHEN NEEDING TO MERGE WITH TRAFFIC. THIS IS A DANGEROUS SITUATION AND FEEL HYUNDAI NEEDS TO COME UP WITH A SOLUTION TO FIX THESE VEHICLES BEFORE SOMEONE LOSES A FAMILY MEMBER. I DON'T WANT IT TO BE ONE OF MINE! OR DO A RECALL.

STARTING AT ABOUT 12000 MILES, MY CAR WILL AT TIMES FAIL TO ACCELERATE FROM.A STOP. IT HAPPENED AGAIN TODAY AND I HAD TO JAM THE PEDAL DOWN AND MY CAR REVVED TO 7000RPM BEFORE IT WOULD ACTUALLY ACCELERATE. IT KEPT DOING THIS THE WHOLE REST OF THE TIME I WAS OUT AND IT WAS VERY DANGEROUS SINCE I WAS DRIVING ON A HIGHWAY AND COULDN'T GET MY CAR TO ACCELERATE. I TOOK IT TO THE DEALERSHIP AND THEY CLAIMED THERE WAS NO PROBLEM. THIS IS VERY DANGEROUS!

DUAL CLUTCH AUTOMATIC TRANSMISSION STARTED HAVING PROBLEMS AROUND 5K MILES. THE CAR HAS 15K CURRENTLY. THE FOLLOWING PROBLEM OCCURS ABOUT 2-3 TIME DAILY UNDER NORMAL DRIVING 10-20 MILES PER DAY ON SURFACE ROUTS. FROM STOP TO ACCELERATING IN 1ST GEAR THERE IS A MUCH LONGER THAN SAFE LAG TIME BETWEEN THE GAS PEDAL BEING DEPRESSED TO THE CAR ACTUALLY GAINING IN SPEED. IT SEEMS LIKE THE TRANSMISSION IS IN NEUTRAL AND THEN SHIFTS HARD INTO FIRST GEAR. IT DOES NOT MATTER HOW LIGHTLY OR FIRMLY THE PEDAL IS DEPRESSED. IT IS A LARGE CONCERN FOR ME AND MY FAMILY THAT THE CAR WILL NOT ACCELERATE OR PERFORM AS EXPECTED WHEN THE GAS PEDAL IS DEPRESSED. WE HAVE TAKEN THE VEHICLE TO THE DEALERSHIP WITH NO RESULTS OR IMPROVEMENTS. THEY STATED THAT ALL HYUNDAI/ KIA DUAL CLUTCH AUTOMATIC TRANSMISSIONS HAVE THAT PROBLEM- STATING THAT WE SHOULD DEAL WITH IT OR TRADE TO ANOTHER VEHICLE.

I HAVE BOUGHT THIS VEHICLE LAST YEAR. THERE IS A LOUD NOISE WHEN I TAKE OFF AFTER I HAVE STARTED THE CAR AND GO. I HAVE TAKEN IT IN THEY TOLD ME IT IS THE GEAR SHIFTER. [XXX]. THIS CAR HAS NO POWER WHEN YOU TAKE OFF AND THE BRAKES HAVE SQUEAKED SINCE DAY 2.I HAVE TAKEN IT IN AND THEY HAVE SCRAPED THE BRAKES 3 TIMES. I HAVE COMPLAINED AND THOUGHT IT WAS JUST ME UNTIL I HAVE READ MORE COMPLAINTS. THIS CAR NEEDS RECALLED OR YOU NEED TO GIVE PEOPLE THEIR MONEY BACK PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

CAR FAILS TO ACCELERATE MORE THAN THE SPEED OF MAYBE ROLLING THROUGH A STOP SIGN WHEN YOU ARE AT A STOP SIGN YOU CANNOT ACCELERATE AND IT IS VERY DANGEROUS TO PEOPLE BEHIND YOU THAT WILL SMASH INTO YOU AND THEN YOU HAVE TO FLOOR THE GAS PEDAL AND WORRY ABOUT CRASHING INTO SOMEBODY IN FRONT OF YOU. I HAVE TAKEN IT TO THE DEALER AND THEY SAID THERE IS NO PROBLEM AND THEY CAN'T FIND ANYTHING THEREFORE THEY CAN'T FIX IT. I AM MOVING TO FLORIDA WHERE IT IS HOT AND HUMID ALL THE TIME WHICH IS SEEMS THAT THAT IS WHEN THE PROBLEM HAPPENS. I WOULD LIKE A NEW VEHICLE IF THEY CAN'T FIX IT I FIND THIS COMPLETELY RIDICULOUS AND I CAN'T BELIEVE THERE HASN'T BEEN A RECALL ON IT YET AS THERE ARE MANY MANY COMPLAINTS THROUGHOUT THE INTERNET

I PURCHASED MY NEW CAR 8 MONTHS AGO WITH 2 MILES ON IT. I AM SCARED TO DEATH TO PULL OUT FROM RED LIGHTS IF ANYONE IS EVEN INSIGHT AT TIMES. IT SEEMS AS THOUGH IT JUST DOESNT WANT TO GO AT ALL. I CAN FLOOR THE GAS AND IT HESITATES FOR FEW SECONDS AS THE RPMS ARE VERY HIGH ALL YOU GET IS A ROLL INTO TRAFFIC. IT MAKES ME SO NERVOUS AT TIMES DRIVING THIS VEHICLE. WORSE MISTAKE BUYING THIS VEHICLE AND WORSE PART IS I WILL BE STUCK IN AS ITS NOT WORTH HALF OF WHAT I OWE ALREADY. THIS SHOULD BE SOMETHING DISCUSSED BEFORE SIGNING OR NOT ON THE MARKET TO SELL AT ALL

I PURCHASED A 2018 TUCSON IN A NOVEMBER, RECENTLY I HAVE NOTICED THAT THE VEHICLE STRUGGLES TO ACCELERATE. I WILL CONTACT THE DEALERSHIP TOMORROW BUT I SEE THAT I'M NOT THE ONLY ONE THAT SEEMS TO BE EXPERIENCING THIS PROBLEM. IT SEEMS TO BE GETTING WORSE. IT'S A HAZARD ESPECIALLY WHEN DRIVING IN THE FREEWAY.

VEHICLE FAILED TO ACCELERATE WHILE MERGING INTO TRAFFIC, FORCING ENGINE TO REACH 6.5K RPM ONCE IT BEGAN TO DO SO. HAPPENS FREQUENTLY. MANY OTHER COMPLAINTS ON SAME ISSUE BY VARIOUS OWNERS.

VEHICLE RANDOMLY SLIPS OUT OF GEAR WHEN BREAK IS QUICKLY DEPRESSED WHEN ROLLING FROM A STOP. VEHICLE NEEDS TO BE SHUT DOWN AND RESTARTED. A VERY SERIOUS SAFETY ISSUE. VEHICLE RANDOMLY FAILS TO SHIFT UP WHEN ACCELERATING. ANOTHER VERY SERIOUS SAFETY ISSUE. DUEL-CLUTCH TRANSMISSION IS CLEARLY DEFECTIVE AS DESIGNED.

LEASED A NEW 2018 HYUNDAI TUCSON LIMITED FROM A LOCAL DEALER. NOTED THE HESITATION IN THE ACCELERATION WHEN TEST DRIVING. SALESMEN SAID BRAND NEW ENGINE, GAS, ETC, MOST LIKELY WILL WORK ITS WAY OUT IN DRIVING WITH NEW REFILL OF GAS. NOTICED PROBLEM ALL THE WAY HOME AFTER PURCHASE. CONTACTED DEALER NEXT DAY AFTER FILLING TANK WITH SAME ISSUE, THEIR RESPONSE "ITS A NOTED HYUNDAI USA TUCSON TRANSMISSION ISSUE". THATS IT! REPORTED TO HCA (HYUNDAI CONSUMER AFFAIRS), HAD A CASE NUMBER ASSIGNED VIA AUTOMATED MAIL. NO CALL, NO MAIL FROM ANYONE AT HYUNDAI TO ADDRESS THE ASSIGNED COMPLAINT #. FILED ANOTHER COMPLAINT, RECEIVED A NEW CASE NUMBER, HYUNDAI CONTACTED ME WITH NO INFO ON MY CASE, MY DOCUMENTS SENT OR NO KNOWLEDGE OF THE TRANSMISSION ISSUES WITH THEIR TUSCON 1.6L TURBO, 7 SPEED ENGINE/TRANSMISSIONS. TOOK THEM 3 MONTHS TO FULLY RESPOND TO SECOND CASE NUMBER ASSIGNED DUE TO MANY PHONE CALLS AND MAILS TO THEM ON THE CASE AND NO RESPONSE ON RESOLUTION TO THIS HAZARDOUS ISSUE WITH THE TRANSMISSION. PENDING REGIONAL CASE WORKER TO BE ASSIGNED TO ASSESS THE TRANSMISSION AT THE SAME DEALER WHERE PURCHASED. *DT

WHILE DRIVING AND THEN COMING TO A TEMPORARY STOP SUCH AS WAITING FOR A RED LIGHT TO TURN GREEN OR RIGHT ON RED OR MAKING A LEFT TURN; THEN I STEP ON THE ACCELERATOR TO DRIVE, THEN ABOUT 20 YARDS OR SO INTO THE MOVEMENT OF THE CAR, THE CAR STOPS MOVING BUT THE ENGINE IS STILL RUNNING. IT DELAYS FOR ANYWHERE BETWEEN 2 AND 5 SECONDS, JUST ENOUGH TIME FOR CARS TO BE COMING RIGHT AT YOU. IT HAPPENED TWICE IN ONE WEEK, ONCE THE WEEK BEFORE AND ONCE RECENTLY, THE SAME DAY I TOOK THE CAR BACK TO THE DEALER TO SEE WHAT WAS WRONG. IT HAS HAPPENED HERE AND THERE IN THE SEVERAL MONTHS THAT I HAVE OWNED IT, BUT SEEMS TO BE GETTING MORE PRONOUNCED WHERE I AM NOTICING IT MORE. I ALMOST GOT HIT FROM BEHIND TWICE AND ALMOST GOT "T-BONED" WHEN MAKING A LEFT TURN. THE SERVICE DEPARTMENT SAYS IT DID NOT DO IT WHEN THEY TOOK IT OUT (I TOLD THEM IT DOESN'T DO IT ALL THE TIME AND IT PROBABLY WON'T FOR THEM.) THEY SAID THERE ARE NO BULLETINS OUT OR RECALLS AND NO CODES SHOW UP WHEN THEY TESTED IT. WELL I DID RESEARCH AND FOUND THAT THE TUCSON HAS HAD MANY PAST PROBLEMS LIKE THIS (LITERALLY HUNDREDS, IF NOT THOUSANDS) AND THE MANUFACTURER WAS IGNORING PLEAS FROM DESPERATE OWNERS BECAUSE NOTHING WAS BEING ADDRESSED. HYUNDAI FINALLY ADMITTED TO PROBLEMS WITH THE 2016 AND 17 TUCSONS AND DID A RECALL. I FEEL THAT THIS IS A VERY SERIOUS SAFETY ISSUE, ESPECIALLY WHEN I AM NOW AFRAID TO MAKE LEFT AND RIGHT TURNS KEEPING IN MY MIND THAT THIS CAR IS GOING TO HESITATE, STALL, DELAY, WHATEVER YOU WANT TO CALL IT. 5500 HUNDRED MILES ON IT AND I PAID THOUSANDS OF DOLLARS TO BUY IT, I DON'T FEEL SAFE MAKING TURNS AND FEEL THAT THIS ISSUE NEEDS TO BE ADDRESSED AND QUICKLY BEFORE SOMEONE (I HOPE NOT MYSELF ALSO)) GETS INJURED OR KILLED.

AROUND 1500 ,ILES THE CAR STARTED TO EITHER STALL COMPLETELY OR "JUMP" FORWARD IN AL DRIVEMODES, TOOK TO DEALERSHIP , THEY SAID IT HAS TO DO WITH TRANSMISSION BEING ESSENTIALLY A STANDARD. THEY TOLD US THEY RESET THE COMPUTER AND IT NEEDS THIS OCCASIONALLY. REALLY NEVER HEARD OF THAT. OUR GASMILEAGE IS ALSO CONSTANLTY GOING DOWN. NOT HAPPY WITH THE CONSTANT SUDDEN ACCELERTION ESPECIALLY WHEN MERGING ONTO INTERSTATES. BOUGHT THIS THING BRAND NEW FEB 2018.

THIS TRANSMISSION CAUSES THE CAR TO NOT ACCELERATE WHEN IT SHOULD, AND WHEN THE TRANSMISSION KICKS IS THE CAR TAKES OFF TO FAST LIKE IT IS OUT OF CONTROL. SOME TIMES THE TRANSMISSION MAKES THE CAR JERK THREE TO FOR TIMES IN STOP AND GO TRAFFIC. THIS IS UNSAFE AND I'M WEIGHTING FOR SOME ONE TO REAR END ME OR ME HITTING SOMEONE ELSE. I WAS MAKING A LEFT TURN FROM A STOP LIGHT AND THE CAR WOULD NOT ACCELERATE AND HALF WAY THRU THE TURN THE CAR TOOK OFF ON ME BUT I GOT IT UNDER CONTROL. I CANT LET MY WIFE DRIVE THIS CAR AND THAT IS A SHAME BECAUSE WE BOUT IT FOR HER TO DRIVE. THIS CAR IS UNSAFE TO DRIVE AND ALL I GET FROM THE HYUNDAI DEALER IS EXCUSES.IT GOES TO THE SERVICE DEPT.10/6/18 AGAIN.

VEHICLE SEVERELY HESITATES TO ACCELERATE FROM A STOP WHILE IN TRAFFIC (GEAR SHIFT IS IN DRIVE POSITION). FAILS TO ACCELERATE WHEN MAKING LEFT TURNS TO AVOID ONCOMING TRAFFIC. PROBLEM PERSISTS REGARDLESS OF DRIVING MODE SELECTION.

Won’t shift so that I can gain speed

My vehicle bucks when first pulling out. like a manual transmission.

When the vehicle is at a complete stop it will have issues going when I push on the gas. It takes a few seconds to go and it will jerk forward and then go. It doesn't happen every time but it is often enough that it's worry some and could be unsafe.

The car will not go into reverse.

Delayed acceleration from stop. Very unsafe when making a left hand turn as it will take up to 10 seconds for the car to accelerate. This happens often but not always.
