2022 MERCEDES-BENZ C CLASS Recalls Canada & USA – Major League Recalls
2022 MERCEDES-BENZ C CLASS Recalls — Canada & USA
Summary
The 2022 Mercedes-Benz C Class has 5 recalls, the most serious involving electrical and powertrain defects that can cut power to the wheels or start a fire. Loose ground connection bolts on 12V and 48V circuits can cause wiring to overheat and melt, creating a fire risk; on plug-in hybrid models, this can also disable the electric drive system. A similar overheating and fire risk exists at the pre-fuse box, where a loose wire connection can also cause a sudden loss of drive power. On the powertrain side, a transmission wiring harness that is too short can be damaged by contact with the front driveshaft, again cutting power to the wheels. There is also a water intrusion issue: if water leaks into the trunk and short circuits the signal acquisition module, the tail lamps and rearview camera can stop working and the rear seat backrests may fold unexpectedly, with a secondary fire risk. Finally, a small number of vehicles may have a driver's seatbelt that was not installed correctly and can loosen and detach over time, reducing protection in a crash.
On a small number of vehicles, the driver's seat belt may not have been installed properly. Over time, the seat belt could become loose and detach.
Safety Risk
A seat belt that detaches in a crash could increase the risk of injury.
Remedy
Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, reinstall the safety cap on the driver's seat belt.
On certain vehicles, a wire in the pre-fuse box may not have been tightened properly. As a result, the connection could loosen and cause a loss of power to the wheels. This could also cause the wiring to overheat.
Safety Risk
A sudden loss of power to the wheels could increase the risk of a crash. Wiring that overheats can create the risk of a fire.
Remedy
Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to tighten the connection in the pre-fuse box. The dealer will also replace any damaged parts, if necessary.
On certain vehicles, the transmission wiring harness may be too short. As a result, the wiring could be damaged by contact with the front driveshaft. If this happens, there could be a loss of power to the wheels.
Safety Risk
A loss of power to the wheels could increase the risk of a crash.
Remedy
Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to inspect the transmission wiring harness, and re-route it if necessary.
On certain vehicles, the bolts for some 12 V and 48 V ground connections may not have been tightened properly. As a result, the wiring harness might overheat and melt. On plug-in hybrid models, this problem could also cause the electric drive system not to work.
Safety Risk
Wiring that overheats and melts can create the risk of a fire.
Remedy
Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to inspect the ground connections, and repair them if necessary.
On certain vehicles, water could leak into the trunk causing the signal acquisition and actuation module (SAM) to short circuit. If this happens, the tail lamps may not work, the rearview camera may not work, and/or the rear seat backrests could fold on their own.
Safety Risk
A short circuit could create the risk of a fire. Tail lamps that don't work could make a vehicle less visible, and cause a following driver not to recognize that the vehicle is braking or intends to turn. A rearview camera image that does not display correctly could reduce a driver's ability to see behind the vehicle while backing up. These issues could increase the risk of a crash. Additionally, a backrest that folds on its own could increase the risk of injury.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealership to install a cover over the signal acquisition and actuation module (SAM).
