The defect
THE COATING USED TO PROTECT THE ACCELERATOR PEDAL SHAFT IS INCOMPATIBLE WITH THE BRONZE BUSHING THROUGH WHICH THE SHAFT PASSES. OVER TIME, AND IN THE PRESENCE OF A CORROSIVE ENVIRONMENT (WATER, ROAD SALT), THE SHAFT CAN CORRODE INSIDE THE BUSHING INCREASING THE AMOUNT OF FRICTION BETWEEN THE ROTATING SHAFT AND THE STATIONARY BUSHING.
The risk
A CORRODED ACCELERATOR PEDAL SHAFT CAN CAUSE THE ENGINE THROTTLE TO BIND AND NOT FULLY RETURN TO IDLE WHEN THE OPERATOR'S FOOT IS REMOVED FROM THE ACCELERATOR PEDAL INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
The remedy
DEALERS WILL INSTALL A REVISED ACCELERATOR PEDAL AND SHAFT ASSEMBLY.
