Consumer Description

The brake light switch function was inhibited due to the plastic retainer mounted on the pedal assembly. The plastic retainer had become brittle and caused it to come apart in pieces. The retainer acts a point of contact for the brake light switch plunger which signals to the ECM when the driver is applying or not applying the brakes. Symptoms of failure are constant illumination of rear brake lights with vehicle on or off. Disables cruise control. Also most importantly it limits throttle control by reducing throttle range spraticly. No driver warnings or lights are displayed or illuminated on the IPC. Problem has been verified and reproduced by independent service center.
