2022 MERCEDES-BENZ C 300 Recalls — Canada & USA

The 2022 Mercedes-Benz C 300 has 4 recalls, the most serious being three separate electrical fire risks: loose or poorly grounded wiring connections that can overheat and ignite, and moisture that can leak into a trunk-mounted control module and cause a short circuit. The wiring concerns cover a few different failure points: an unsecured ground connection on the wiring harness can cause it to overheat, and a loose bolt at the pre-fuse box can cause a wire there to overheat as well, with either issue potentially starting a fire. The loose pre-fuse box wire can also cut drive power without warning. The trunk moisture issue is separate in its effects: water reaching the signal acquisition module can disable rear exterior lights, cause the rearview camera to stop working, or trigger the rear seat to fold on its own. There is also a front seatbelt concern: the driver-side seatbelt cover may not be properly seated over the tensioner, which can allow the belt anchor to come loose and leave the driver without adequate restraint in a crash.
