The hazard
On certain trucks, the throttle return springs may fail during normal operation without prior warning. If both springs fail, the engine throttle may not return to the idle position when the throttle foot pedal is released. This could result in loss of vehicle control and a possible crash. Correction: Throttle return springs will be replaced.
