Brakes
2022-05-06 · campaign 2022-237
Issue:
On certain vehicles, corrosion could cause the brake booster to fail. If this happens, there may be an increase in brake pedal effort and increase the distance needed to stop the vehicle. In rare cases of severe corrosion, the brake booster could separate completely and cause a loss of brakes.
Safety Risk:
A loss of brakes can increase the risk of a crash.
Corrective Actions:
Mercedes-Benz advises you to stop driving your vehicle immediately. The company will notify owners by mail and instruct you to contact a local Mercedes-Benz dealership to arrange for towing and an inspection. The dealer will remove the rubber brake booster sleeve and determine whether the vehicle is safe to drive or if it can't be driven and a parts replacement is necessary. Also, depending on the results of the inspection, you may need to return within two years for a re-inspection.
Seats and restraints
2006-04-10 · campaign 2006-076 · 113 vehicles
On certain vehicles, the nuts used to anchor seat belt buckles of the second row seat may not have been manufactured correctly. The screw threads in the nuts may be missing. The seat belt buckles could separate from the seat assembly during a vehicle crash. If a separation occurred in a crash, seat occupants may not be properly restrained, increasing the risk of personal injury. Correction: Dealers will inspect and, if necessary, replace second row seats.
Electrical
2006-03-29 · campaign 2006-070 · 690 vehicles
On certain vehicles, the starter wiring harness may have been routed incorrectly and could chafe. Over time, such chafing could wear through the protective sleeve and cause an electrical short.
