“I am reporting another Toyota sticky accelerator pedal. Our 1999 Sienna minivan has had 3 incidents of stuck accelerator, the most recent was jan. 21, 2010. I believe it has become stuck between 40 and 45mph. Other incidents were in summer (cannot remember date) and october 2009. The 1st incident was brief and corrected quickly by pushing down on the pedal to free it , the 2nd incident required braking and putting the car in neutral and shoving the pedal with my foot to the left and right to free it up. …”
