On certain vehicles, the recall repairs completed by a Mercedes-Benz dealer during recall 5491309 (Transport Canada recall no. 2022-397) may not have been done correctly. As a result, a second repair is required. On certain vehicles equipped with 4-wheel drive (4Matic), the transmission wiring harness may not be routed correctly. As a result, water could enter the wiring harness connector and cause a short circuit. Note: This recall replaces Transport Canada recall no. 2022-397.
A short circuit can create the risk of a fire, even while the vehicle is parked and turned off.
Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to replace the transmission wiring harness.
On certain vehicles, the 12 V battery (in the trunk) could move in a crash. As a result, the battery electrical connexions could detach. If this happens, the post-crash safety systems (like the emergency calling (eCall) system, electric seat adjustment, hazard warning lights, and automatic door unlocking) may not work.
Safety systems that don't work correctly could increase the risk of injury.
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealership to add a bracket to better secure the battery.
