The vehicle severely shudders, jerks, and hesitates from a stop and while making a turn, during both acceleration and deceleration, making it entirely unsafe to drive. The vehicle has been completely un-driveable for the past 6 days. The check engine light illuminated, and on 4/9/26, the dealer documented a failed transmission judder test and kept the car, issuing a loaner. A temporary software patch failed after two weeks. Upon return, the dealer reported they were unable to recreate the problem, recommended returning when the vehicle demonstrates the problem more frequently, and refused to mechanically repair the dual-clutch transmission under my active original-owner 100,000-mile powertrain warranty, basically instructing me to continue to drive a seriously un-safe vehicle. Most recently, a yellow dashboard warning light illuminated, and the vehicle entered a dangerous 'limp mode,' severely restricting power and struggling to move before the light cleared after cooling down. The vehicle is completely un-driveable and parked.

Oil drains very fast even with regular oil changes and maintenance. The vehicle began shaking and then completely stopped with very little warning. Check engine light flashed for under 60 seconds then vehicle would not move forward on the highway creating a major safety hazard. Engine smelled hot and like burning rubber.

Hyundai Tucson Sport 2016 GDI engine. I am the original owner of this truck I have taken care of this truck so much it being my first brand new purchase. No oil leaks NOTHING! When I first purchased the vehicle I noticed that it would stall when I would accelerate but did not think too much of it since it was brand new. A few years passed started to notice frequent oil changes were supposed to be made. Another few years turbocharger went out had to get it replaced. The engine consumes so much oil at first I thought it was because the turbocharger was out so when I got it fixed I thought that would fix that issue and it didn’t. I got an oil change March 2, 2026 and on March 21, 2026 I was on the highway and the truck started to shake really bad I exited the highway went straight to the oil place they said I had no oil on the dipstick I got ANOTHER oil change (expensive) and when I turned on the car to leave the car shook again and the engine light was flickering on and off and finally stayed on the dash board. Barely made it home. Got a tow truck to tow it to Hyundai dealership they told me they will not see it unless I pay the diagnostic fee of $200 and even then they think it’s the engine with everything I described to them. They said since there are no recalls on the Tucson that Hyundai will not do anything for me I would have to pay out of pocket for everything. Had to pay the tow truck again to tow it to my house ($250). My car has all the symptoms all the other cars have that they have recalled. This is a huge safety issue because i drive on the highway a lot and everyone knows a car with no oil is extremely dangerous.

The contact owns a 2016 Hyundai Tucson. The contact stated that the check engine warning light was illuminated, and there was a ticking sound coming from the front of the vehicle. The vehicle was taken to Auto Zone, where a mechanic diagnosed the vehicle with a knock sensor failure. The knock sensor was replaced. The mechanic informed the contact that the vehicle was included in Manufacturer Campaign: CS966 for the transmission control module (TCM). The vehicle was taken to the dealer, who confirmed that the vehicle was included and the software update was performed. After the vehicle was repaired, the check engine warning light was no longer illuminated; however, approximately 30 minutes later, the vehicle failed to exceed 35 MPH, and the check engine warning light started flashing. The vehicle was returned to the dealer, and the contact was informed that the software update caused the vehicle to enter LIMP Mode to protect the engine. The dealer informed the contact to drive the vehicle for 30 days or a total of 500 -1000 miles, and if the vehicle continued to enter LIMP Mode or failed to operate as needed, to return the vehicle for the engine to be replaced. There were no additional repairs performed. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

The car has been diagnosed with internal engine failure by both an independent service center and a dealership service center. The issue was described as a rod timing issue causing knocking, leading to failure of the engine. A light was not on for a majority of the issue but did start flashing before car became completely undrivable. The car was sold to me with this issue and has been driven for nearly 3 years with a power loss issue that was dismissed as turbo lag or other issues. Driving a car with this issue that does not alert with a check engine light is a major threat to driver and passenger safety as it can result in engine seizure and vehicle fires. The engine issues began at the least before 58,000 miles, with total failure occuring at roughly 96,000 miles. Hyundai is known for this issue, particularly in turbo model engines. Only once during ownership of the car did the check engine light come on prior to engine failure. When checked, it was described as a catalytic converter issue. The service center also did an oil change on the car, and the light went off. The check engine light did not come on again for more than a year. The check engine light did not come on until after the issue was diagnosed by the independent service center it was taken to in January 2026.

There is a major problem with certain year Hyundai vehicles from 2016-2021 with the engine burning oil and clogging up the exhaust. My moms vehicle has been at dealership for evaluation and combustion cleaning multiple times and the problem still continues. There has been times where she is driving car and it starts to bog down and loose power which is a safety issue especially if on highway. The vehicle is burning oil, occasionally have to add oil. The engine light does come on at times. The car has been at dealership for recommended oil consumption test at every 1000 miles and has not passed. Combustion cleaning done each time and sent on way. Called and made complaint with Hyundai corporate and and got no where. The tech department at Hyundai factory gave dealership recommendations to do which were completed and still having same issue. The factory was only willing to cover 70% off the cost of new catalytic convertor and my mom to be responsible for remaining balance. Hyundai claimed that the convertor was out of warranty 8 years/80,000 miles even though this has been going on for past 2 years. This is not a problem caused by consumer but an issue with factory. Hyundai not living up to there 10 year/100,000 mile warranty as they advertise. There are facebook groups with people having same problems as we are with dealership not really doing anything other than combustion cleaning as advised by factory and corporate not doing anything either. I believe this is a major safety/defect issue with engines in these Hyundai Vehicles . What happens when someone is on the highway and the vehicle bogs down and another vehicle comes from behind and slams into you?

On my husband's way home from work he explained to me that the car had a "hiccup" and then an engine light blinked on, then it died at an intersection. He was pretty close to home so he got it started again and drove it home. He replaced spark plugs and coil packs and it still had a misfire. We took it to an auto repair shop where they did a scan and told us it had a dead hole in cylinder 2 and that it needs a full engine replacement. The car also had an oil change just before Thanksgiving. My husband checks oil regularly and added a quart a month before the oil change and it seems to consume more oil then it should.

While driving under normal conditions, my engine experienced a sudden and catastrophic failure. The check-engine light illuminated, the vehicle began shaking violently, and I was forced to pull over immediately due to safety concerns. There was no prior warning and no oil pressure or oil warning light activated at any time before or during the failure. After stopping safely, I checked the oil level and found it lower than expected. I added oil as a precaution, but the condition did not improve and the vehicle became inoperable and required towing. The engine assembly remains intact and available for inspection upon request. This failure posed a serious safety risk, as the loss of engine function occurred without warning while the vehicle was in motion, creating the risk of stalling or loss of control. The vehicle was inspected by an authorized Hyundai dealership. Hyundai Motor America denied warranty and goodwill assistance, citing mileage and alleged insufficient maintenance documentation, despite the vehicle being within the 10-year powertrain period and despite the nature of the failure. Routine maintenance was performed throughout ownership; however, some historical service records are unavailable due to the age of the vehicle and changes in service locations over time. Multiple facilities no longer retain records from that period. Notably, no oil warning indicators never activated, which raises concern regarding the failure mechanism. Hyundai has acknowledged widespread engine issues in this engine family involving oil consumption, bearing failure, and sudden engine seizure. The symptoms and progression of this failure closely align with those known defect patterns. This complaint is submitted to document a sudden engine failure presenting a clear safety concern and to assist in identifying potential defect trends. This car has undergone previous engine repair, AC condenser and entire turbo by their service department previously 2022 & 2024 respectively.
