2016 HYUNDAI TUCSON Complaints

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?

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.

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.

Numerous issues with this vehicle. Now, when having oil change, told by the hyundai service center that it is using excessive oil and may need a new engine. In researching this problem, have discovered hyundai has had several problems with excessive oil consumption in their many of their hyundai vehicles, including the 2016 Tuscan

My 2016 Hyundai Tucson experienced engine failure consistent with known Hyundai engine defects. After reporting multiple battery outages, rapid oil consumption, and limited acceleration ability, outstanding warranties were checked and updated. However, the issues persisted, and the engine failed suddenly while I was driving. Hyundai denied warranty coverage without proof of the issues being unrelated to the warranty. This presents a serious safety hazard due to unexpected engine failure.

The contact owns a 2016 Hyundai Tucson. The contact stated that after coming to a complete stop, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The vehicle went into LIMP Mode. In addition, the vehicle failed to accelerate above 30 MPH. No warning light was illuminated. The vehicle was taken to several dealers. The contact was informed that the unknown hoses and the dipstick melted inside due to the engine overheating. The contact stated that the catalytic converter was replaced; however, the failure persisted. The contact stated that the catalytic converter had been replaced three times since the first failure. The contact stated that on a separate occasion, the engine was consuming an excessive amount of engine oil. The contact was adding engine oil every two weeks. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The failure was a recurring failure, and the contact drove the vehicle intermittently due to the safety concerns. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

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.

Car died/lost power while driving in traffic 11/28/25. Good Samaritan was kind enough to push me off the road out of traffic. Car was towed to Hyundai dealer that day, then 12/1 told engine failure, required engine replacement. Class action lawsuit settlement for engine replacement, but denied by Hyundai because of "neglect", since I am not able to locate all of the service records that they request. Known faulty rotating assembly, and Hyundai has implemented concerted practice of denying warranty coverage for failed engine. Now having to pay almost $8K to replace with new engine, but concern that new engine will have same issue. (multiple posts about this). There was high potential for significant traffic collision, injury due to sudden, catastrophic engine failure. Traumatic experience.

While driving on the highway at normal speed, the vehicle suddenly lost power and shut off without warning. There were no warning lights or messages prior to the loss of power. I was able to safely pull over, but the engine would not restart at that time and the vehicle required towing. The sudden engine shutdown occurred in active traffic and created a safety risk due to loss of propulsion. The vehicle later restarted, but I brought it to an authorized Hyundai dealership for inspection. The dealership diagnosed internal engine damage, including piston ring failure and cylinder wall scoring, and advised that the engine would need to be replaced. Since the incident, the vehicle has shown intermittent oil pressure warning lights and reduced performance. The issue has been confirmed by a dealer inspection. The vehicle is currently not considered reliable or safe for regular driving.

Drove into a parking space, with the foot pressing on the brake pedal, the car suddenly and without warning rapidly accelerated uncontrolled causing the vehicle to accelerate past the end of the parking space causing property damage.
