On a small number of trucks, the high-voltage inverter cable may not have been tightened properly to the junction box. As a result, the connection could become loose and cause electrical arcing (sparks). If this happens, the high-voltage system could shut down and cause a sudden loss of power to the wheels.
A sudden loss of power to the wheels could increase the risk of a crash.
Daimler Truck North America (DTNA) will notify owners by mail. The corrective actions for this recall are under development.
