2012 Hyundai Genesis Owner Comments

problem #6

Jan 142016


  • 12,180 miles


I was turning to park in my parking space and all of a sudden the car began to accelerate with such speed that I thought it would jump the curb and crash into my home. I was unable to stop the car and the brakes were unresponsive. It hit the curb and finally came to a stop with a terrible shudder/noise.

Genesis 6-cyl

  • 8,500 miles
While driving 25 mph I tried to accelerate the vehicle to avoid collision. Vehicle hesitated to accelerate for a few seconds when accelerator pedal was pressed. Later I tested a vehicle noticed similar consistent hesitation at various speeds. Took vehicle to the dealer. Hesitation was recreated and documented, however dealer was unable to find anything wrong with the vehicle and based on that stated that condition is normal, refusing repair.

The vehicle accelerated without the gas pedal having a force applied thereto and with the brake pedal being depressed. Once the automatic transmission was placed in park, the engine operated at over 3,000 RPM without the gas pedal being depressed. Once the engine is turned off and restarted the vehicle operates normally for a short period of time.

Genesis 8-cyl

  • 16,250 miles
Auto hold technology feature failed at a stop light. When on, auto hold illuminates white, and green when it is actively holding the vehicle in place, without the need to depress brake pedal. On a stop light car jerked forward and the auto hold illumination turned orange in color from green. Auto hold feature would not reset even when restarting vehicle. Dealership was able to reset, citing a shortage in the auto-hold unit, with a replacement part ordered. Potentially dangerous if there was anyone in front of the vehicle at the time of failure, as it could of resulted in a potential injury.
