I was trying to park my vehicle in a soccer field parking lot. As I slowly turning right into my spot at about 3-5mph, my foot was lightly depressed on brake pedal and about to come to a complete stop, the vehicle suddenly made a very loud engine sound (my foot was still on the brake pedal and not on the gas pedal) as the engine rev up for about a second or two then accelerated forward jumping the curb and hit a big fence pole which stopped the vehicle. The vehicle felt like it sped up from 3mph to 30mph and I had no time to react. The front passenger side badly destroyed and the vehicle is totaled. The car was five years old and about 75k miles. It is very safety concerning and should be seriously look into.
