2010 Hyundai Elantra: sudden unintended acceleration

Filed Aug 2, 2017 · Acceleration · VA · crash

As the brakes were applied when slowly (<10 miles/hr) turning into a parking place in a parking lot of a strip mall perpendicular to the side walks (double sidewalk separated by a railing) in front of the stores, the car suddenly accelerated thru the parking space and up on the first sidewalk (it did not respond to the brake pedal pressure to slow) and knocked down the railing separating the first and second side walks. The driver pulled up on the handbrake to stop the car before it crossed the second side walk and crashed into the barbershop thus preventing further damage and no injury.
