The issue
Issue: On certain trucks, the brake modulator valves could corrode. As a result, the brakes on one wheel could fully apply during an adaptive cruise control braking event. If this happens, there could be a brake pull that can cause the truck to change direction. Note: This problem does not affect the regular service brakes. Safety Risk: A brake pull that causes the vehicle to change direction suddenly can increase the risk of crash. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to inspect, and if necessary, replace the brake modulator valves.
Description (français)
Problème : Sur certains camions, les soupapes du modulateur de frein pourraient se corroder. Par conséquent, lorsque le régulateur de vitesse intelligent est activé et que le système doit freiner, les freins d'une seule roue pourraient s'appliquer complètement. Si cela se produisait, il pourrait y avoir un déséquilibre au freinage qui pourrait faire changer le camion de direction. Remarque : Ce problème ne concerne pas les freins de service ordinaires. Risques pour la sécurité : Un déséquilibre au freinage qui fait que le véhicule change soudainement de direction peut augmenter les risques d'accident. Mesures correctives : Daimler Truck North America (DTNA) doit aviser les propriétaires par la poste et leur demander d'amener leur camion à un centre de service autorisé de DTNA pour faire inspecter et, au besoin, remplacer les soupapes modulatrices de freinage.
