One problem related to accelerator stuck has been reported for the 2000 Lexus RX300. The most recently reported issues are listed below.
2000 Lexus Rx300. On 3 occasions, in 2006, the car's gas pedal was stuck in the down position - therefore I was unable to stop the vehicle. Took the vehicle to Lexus dealer 2 times (there are records of that), called them once, was told it was safe. After the 3rd time with the pedal sticking, had to sell vehicle. Frequency of appearance - it all happened within 10 days. Could not duplicate for Lexus dealer to fix the problem.
