What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
It lost power and slowed down quickly to below 40 mph. It didn't help to press down the gas pedal. I was forced to switch from the middle lane to the passing lane in order to reach the shoulder. The car was side swept by another car in the passing lane because it was at low speed.
On 08/13/2021 my wife was involved in an accident where the front air bag did not deploy causing her to hit the steering wheel and break her sternum casing extreme pain. We need to understand why the front air bag did not deploy?
Apparently, a front-end collision occurred while the vehicle was parked and unoccupied in a parking lot resulting in $1232 in damage to body parts, anti-collision radar, and electronic cruise control. Astonishingly, the bumper and even the front license plate sustained almost no visible damage whatsoever.
A partially engaged connection risks arcing and fire. Charging failure also depletes the traction battery, cutting power available for merging and evasive maneuvers. Incident: Without warning, the connector would not release. It took ~30 minutes to free the charger.
Hyundai's own shop manuals state: "Never allow technician to work on high voltage systems who are not wearing personal protective equipment." Hyundai TSBs for hybrid repairs require insulating gloves rated at 1000V AC/1500V DC.
Many times, when I back out of my driveway into the intersection in front of my house the vehicle hesitates for several seconds when shifted from Reverse to Drive. I am in a situation where I cannot accelerate if needed out of the intersection. This is a safety issue in my opinion.
The rear driver's side seat belt completely detached from the shoulder attachment point.
Seat belts are stuck and most times does not get intact or reset after you get out of car seat. It has been happening over a month.
