Consumer Description
The vehicle is a 2020 Hyundai Tucson with AWD. Current mileage of the vehicle is 58,309. In the last 10K miles, there have had 4 separate instances of a sustained flashing check engine light that has put the car into limp mode. Since the first instance, a knock sensor, catalytic converter, and spark plug coil, among other things, have been replaced. However, the issues persist and have yet to be resolved. The engine continues to misfire, resulting in dangerous driving situations. Most recently (XXX) the car went into limp mode on an interstate highway where the vehicle was unable to accelerate and could not exceed 2000 RPMs. The code scanner read P1326 - Glow Relay Short Circuit. This was just a week after the vehicle was towed to McGovern Hyundai in Brockton, due to the car being in limp mode (XXX) and the vehicle was given a clean bill of health. I was told that there was no cause for concern and the code was cleared. I’m extremely concerned about this issue with the vehicle and don’t feel that it is safe to drive, especially when it loses power on the highway. The vehicle is insured, but has not been inspected by an insurer. Nor has the vehicle been inspected by police. The car has been inspected by the dealership, but that have not produced any findings. The car is certainly available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
