While driving at a high rate of speed propulsion to the vehicle suddenly and without warning ceased, the electric and internal combustion engine were non-responsive (ICE stopped; hybrid motor didn’t provide propulsion), the warning light said ‘Check Hybrid System. Turn off engine’ I was put at risk because I was traveling at highway speed and was given no warning before the vehicle shut down. This has occurred nine times, I’ve reported all to Hyundai, they have had the car in the shop three times, the issue is not fixed. No, despite ODB2 error codes, the car has not shut down while a dealership is driving it. Yes, the vehicle has been inspected multiple times by Hyundai. Yes, always ‘Check Hybrid System. Turn off engine’, in almost all cases the check engine light comes on after that, and in some cases additional lights such as ‘auto hold’. This first occurred in Dec 2023, I was told the car was fixed (it wasn’t) and happened again in October 2024. I haven’t been able to drive my car since then.
