The issue
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.
Description (français)
Sur certains camions, il y a risque que les ressorts de rappel du papillon des gaz fassent soudainement défaut en cours de fonctionnement normal. Si les deux ressorts font défaut, le papillon des gaz (du moteur) peut ne pas reprendre sa position de ralenti quand cesse la pression sur la pédale d'accélérateur. Il pourrait en résulter une perte de maîtrise du véhicule, voire un accident.
