| Tl* the contact owns a 2007 toyota highlander hybrid. when applying pressure to the brake pedal, the engine would occasionally rev making braking more forceful. he speculated that the engine control system failed. the vehicle was taken to an authorized dealer for inspection. the technician stated there was no diagnostic testing equipment available to detect the malfunction. the failure mileage was 40,000. the current mileage is 42,000. updated 02/1710 *bf updated 02/19/10 updated 03/02/10 the consumer believed the problem was engine idle, not accelerating or braking. 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. updated 04/09/10.*jb the consumer stated he experienced sudden acceleration again. updated 05/03/10 | |||
