Three problems related to vehicle speed control have been reported for the 2003 Lexus GS300. The most recently reported issues are listed below.
The contact owns a 2003 Lexus Gs300. The contact stated that he depressed the brake pedal and the vehicle accelerated, causing him to crash into another vehicle. There were no injuries. The vehicle was taken to the dealer for inspection but they could not diagnose the cause of the failure. The contact also stated that as a mechanic test drove the vehicle, the engine caught on fire due to a short in the electrical wires. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 89,000.
While stopping the vehicle sometimes the brake distance is extended as the car is slow to stop. On a regular bases the vehicle brake pedal sticks to the floor while stopped at a light, I then have to pull the pedal up with my left foot to begin acceleration. When approaching slower traffic as the traffic resumes at regular speeds the brake pedal sticks and continues stopping the car.
Unexpected acceleration. On several occasions, primarily while stopped at a traffic signal, my vehicle would lunge forward. I took it to the dealer and was told they had no record of a problem of this nature for this vehicle. They could not find anything wrong. I saw a article on the internet that the NHTSA was investigating similar problems with other Toyota products.
