Defect
On certain vehicles, the screws holding the engine bay fuse box could become loose over time. If this happens, the fuse box could vibrate excessively, which could damage the fuses inside. Damaged fuses could cause certain vehicle functions to stop working without warning. As a result, the engine could turn off, there could be a loss of power steering assist, and/or the ESP and active brake assist systems could turn off.
Safety Risk
A sudden loss of engine power, power steering assist, ESP system and/or active brake assist could increase the risk of a crash.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to inspect and tighten the screws holding the fuse box, if necessary.
