Faulty spot welds on the metal bracket thats holds the accelerator pedal assembly to the firewall broke loose. Spot welds full of air pockets. Showed it to the dealer, but they would not honor the defect. 38000 miles and its real nice to have the gas pedal to hang by the throttle cable. Thank goodness it happened in the driveway and not pulling out into traffic!.
