2014 Hyundai Tucson engine problems

“Complete engine failure in July of 2024. When the car was sold to us it was under recall and not repaired and we were not told there was a recall. When the engine failed we were told we were at fault because we failed to get the recall addressed.”

“The contact owns a 2014 Hyundai Tucson. The contact stated that while driving 40 MPH, the vehicle started making an abnormal ticking sound. While accelerating, the sound level increased. The contact stated that the failure was related to the engine warranty extension TXXM. An independent mechanic was contacted and determined that there was an internal failure with the engine. The fluid levels were topped off; however, the sound continued while driving. The vehicle was towed to the local dealer and the dealer declined to replace the engine due to incomplete updates. The warranty was not transferred. The vehicle was not repaired. The vehicle was purchased from Enterprise Rental Car, and the warranty was not transferred to the owner. The manufacturer was contacted and opened a case. The failure mileage was approximately 134,000.”

“My truck started knock and losing power as I drove it. I took it to get serviced put the machine same is was a recall on the engine. I took it to the Hyundai dealership with in 2 weeks he said it was rejected by Hyundai to replace my motor. I service my car but they said I didn't. If it's a recall and not my fault.”

“The contact owns a 2014 Hyundai Tucson. While the contact's wife was driving at an undisclosed speed, several unknown warning lights illuminated, and the vehicle lost motive power. The contact's wife was able to coast the vehicle to the shoulder of the roadway. The vehicle was towed to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was advised to have the vehicle towed to the dealer. In addition, the contact was informed of Campaign 953 (Extended Warranty on the Engine). The vehicle was later towed to the dealer, where it was diagnosed with engine failure.

“On 10/13/25, I was driving on a state hwy & lost all power. All of my warning lights came on. I managed to pull into a driveway & when I tried to start it, puffs of smoke were coming from under the hood. I got it to my mechanic & he said my starter was burnt up. He replaced the starter & discovered that my engine is seized up. It was a scary incident especially driving on a busy state highway. It put my life & others lives in danger. There were no warning lights on prior to this. I acquired the vehicle in February from a car lot. I have had it serviced regularly.”

“While driving at approximately 70MPH on the highway, my 2014 Hyundai Tucson Limited suddenly locked up with no warning lights, no noise and no prior symptoms. The engine completely seized, causing immediate loss of power. I was barely able to coast off the highway exit to a final stop on the feeder shoulder, in a desolate area. The vehicle has always been properly maintained and is in excellent condition. Upon research, I learned that Hyundai has known of internal engine defects caused by metallic debris left from manufacturing since 2010, which can cause bearing failure and engine seizure. My Tucson's failure matches the same pattern described in Hyundai's Theta II engine recall and warranty extension campaigns. This sudden failure created an extremely dangerous situation at highway speed and possibility of injury while being stranded on an open road. Many owners, myself included, were never properly notified of the risks. I am filing this report because this incident represents a serious safety defect and potential recurrence among similar vehicles that may not yet be covered by recall. I respectfully request that the National Highway Traffic Safety…”
