UPDATED 03/22/10.*JB THE CONSUMER STATED THE PROBLEM HE EXPERIENCED WAS NOT DUE TO A STUCK ACCELERATOR, BECAUSE THE ACCELERATOR PEDAL ALSO RUNS THE HYBRID MOTOR. THE HYBRID MOTOR IS NOT ACCELERATING THE VEHICLE LIKE THE GAS ENGINE. IF THE GAS PEDAL WAS THE PROBLEM, THE VEHICLE WOULD STILL RUN AWAY IN ELECTRIC MOTOR. THEREFORE, IT IS DEFINITELY AN ENGINE PROBLEM, NOT AN ELECTRIC MOTOR OR ELECTRIC GENERATOR. AND IT IS SOMETHING THAT CONTROLS THE ENGINE AND THE HYBRID ELECTRIC MOTOR.
