One problem related to accelerator stuck has been reported for the 2002 Lexus RX300. The most recently reported issues are listed below.
Whenever at a stop or going at very slow speeds (less than 10mph, for example), gas pedal sticks. I have to apply pressure or stomp on the pedal to get the car to move, then it often lurches ahead. This does not happen if going at speed (25 + mph) when take foot off gas pedal nor does it happen when putting car into reverse. At times have to apply excessive pressure to get the gas pedal to move, other times not as much pressure. So far have not done anything to repair the sticking gas pedal. Problem has been getting progressively worst since late last year.
