NHTSA Complaint #11711041 — 2016 HYUNDAI TUCSON

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.
