I agree, I had a hot 327 Chevy Impala run away with me when the motor
mounts broke. Standing on the brakes choked the engine down. Since the
computer also controls braking on the Prius I wouldn't doubt if that
is malfunctioning too.

Did you see the latest on the news tonight? He hit the brakes many times in
short burst (probably to heat them up) not in the long "stand on" he stated.
Seems they wee found to be working properly.
