On a small number of vehicles, the engine compartment firewall may not be sealed correctly. This could allow water to leak inside the vehicle. If this happens, electrical components could short circuit. This could also affect the Pre-Safe system or cause the vehicle not to start.
Safety Risk
A short circuit could cause emergency systems not to work, which could increase the risk of injuries in a crash.
Corrective Actions
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealership to reseal the front wall.
