October 2025 while driving the vehicle at highway speeds, vehicle started bucking, losing power and then stalled. The check engine light did not come on. I was able to get off the side of the road and had it towed to the dealer. Dealer found injectors to be leaking and replaced all 4 GDI fuel injectors-mileage was 29,598. On July 1, 2026, again the same issue while driving the vehicle at highway speeds, it started bucking, losing power and stalling when slowed. This time the check engine light came on. Again, it was undrivable and had to be towed to the dealer. Dealer found after 15,000 miles, some of the new injectors failed and were leaking and all 4 GDI injectors were replaced again-mileage 44,492.

I have filed a report with Hyundai National Consumer Affairs because the vehicle will be out of warranty...

When I attempted to back the trailer into a driveway, the open tailgate was caught between the vehicle and the trailer, causing serious damage to the tailgate as well as the trailer that was being towed.

This problem has been reported to both my local Hyundai dealership as well as to the Hyundai Corporate Case Management group (HCCM). (case #[XXX] of the HCCM) The dealership attempted to reproduce the incident while the vehicle was parked in the shop and was unable to duplicate the condition that happened while driving on a rough public road, towing a trailer. No warning lamps or messages appeared prior to the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FO...

While driving my vehicle on a two-lane highway, I experienced multiple sequential electronic system failures (including the vehicle no longer detecting the smart key), and all electronic systems on the car became inoperative. I lost all instrumentation, including my speedometer and tachometer. At the same time, I also experienced a loss of motive power, and the engine of the vehicle began running extremely erratically before completely cutting off. I attempted to make a safe stop on the side of the road, but after doing so, could not restart the vehicle. The electrical systems of the vehicle continued to behave erratically, and the engine would not restart. I contacted roadside assistance, but they were unable to start the vehicle as well. It was towed to my local Hyundai dealership, but instead of expressing any genuine concern for the significant risk I endured while being placed In harm's way, they refused to fully diagnose the vehicle, and instead accused me of "jumping in reverse,...
