Reported at 25,000 miles, March 2023 FireInjury

On [XXX], the vehicle was involved in a complex multi-impact accident. It was struck by a vehicle on the passenger (right) side and, simultaneously, by another vehicle on the driver's (left) side. (Police Report). During this sequence of collisions, and despite the magnitude of the impact, I must express my extreme concern that the left side airbag (driver's side) did not deploy. This failure caused Mr. [XXX] , the undersigned, to suffer a neck injury as a direct consequence of the incident.

May 2025 CrashInjury

Severe hesitation when attempting to accelerate from a stop.

This has been an ongoing problem with this car, has not been rectified , hyundai refuses to acknowledge the problem.

Reported at 10 miles, December 2020

Received recall notice that the possibility exist that a battery compartment fire could happen. Recall notice also stated that vehicle should 'not be parked indoors.' the recall notice also stated 'an electrical short in the ABS module could increase the risk of an engine compartment fire.' so we don't dare park the car in our garage since it is located beneath our home, thereby leaving a new car out in the elements at all times.
