Defect
On a small number of vehicles, the electronic stability program (ESP) control unit may have been damaged during assembly. As a result, water could leak into the control unit and cause a short circuit. If this happens, the vehicle stability control and antilock brake system (ABS) could turn off.
Safety Risk
A short circuit could create the risk of a fire. A loss of vehicle stability control and/or ABS could increase the risk of a crash.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealership to replace the ESP control unit.
