2023 MERCEDES-BENZ C 300 Recalls — Canada & USA

The 2023 Mercedes-Benz C 300 has 3 recalls, the most serious being two separate electrical wiring defects that can cause wiring to overheat and start a fire, with one also capable of cutting drive power without warning. In both cases, loose or improperly secured connections allow electrical current to build heat in the wiring. One involves ground connections in the main wiring harness; the other involves a bolt on the pre-fuse box that may not be fully tightened, and that particular fault can also cause a sudden loss of drive power while moving. There is also a front seatbelt concern: the driver-side seatbelt cover may not be properly seated on the tensioner, which can allow the belt anchor to work loose and leave the driver with a belt that does not hold properly in a crash.
