Brake lights or turn signals that do not work could cause a following driver not to recognize that a vehicle ahead is braking or intends to turn. This could increase the risk of a crash.
Newmar will notify owners by mail and instruct you to contact a Daimler Trucks North America (DTNA) authorized service facility to schedule a repair. The service facility will install a new wiring harness bypass.
