Vehicle in reverse backing up on steep driveway, foot on fuel pedal, car began its automated hill holding function, while in reverse, heard high rpm, transmission was slipping into neutral, car began rolling forward, put foot on brake, brake failed, car accelerated rapidly, and engine died, then hit the wall inside the garage. I estimated, speed at time of impact approximately 10 to 15 mph. Noticed another entry filed similar to this,had same fuel, brake fail symptoms.
On 5/15/14 at approx. 0430am, while at a stop light, the vehicle experienced unintended acceleration. With my right foot on the brake pedal the car suddenly accelerated. Because my foot was on the brake pedal the car moved less than two feet. I then placed the automatic transmission into neutral, where the motor rev'd to approx. 7000 rpm. I then immediately turned the car off, and then back on. After turning it back on, the car then resumed normal functions. Later the same day I took the vehicle to my local kia dealership. According to the serviceman, a comprehensive analysis was performed, however they were unable to duplicate the issue.
