Issue: Under certain conditions, a software problem could cause too much fuel to be injected into the engine. As a result, the exhaust system could overheat and cause the engine wiring harness to melt. If this happens, there could be a sudden loss of power to the wheels. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Additionally, wiring that melts could create the risk of a fire. Corrective Actions: Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to update the engine control unit software.
