My wife was pulling her car into a parking area consisting of a few small storefronts. When pulling in, the brakes completely failed as did the forward collision warning system and the automatic emergency braking system. As she continued to press the brake pedal it just went to the floor of the car. The end result was that the car struck one of the storefronts causing damage to the building as well as her car. Fortunately the store was closed at the time and no one was injured, nor was she. There were not any warning lamps or messages prior to the brakes failing. The brakes worked fine in the approx. 15 minute drive prior to the accident. I realize that drivers sometimes press the accelerator in error instead of the brakes and I can assure you that this was not the case (we wife is not elderly and is a very safe driver). We spoke to the auto body shop who will be repairing the car and they told us that the brakes currently seem to work. A online search revealed that this problem as been reported / discussed by others in the past. We expect to have the car repaired and returned to us in the next week but are very concerned with driving it as another accident could be fatal.
