Mercedes-Benz CLA

Issue: 
On one vehicle, the recall repairs completed by a Mercedes-Benz dealer during recall 5496507 (Transport Canada recall no. 2025-527) may not have been done correctly. As a result, a second repair is required. 

On certain vehicles, there could be a problem inside the high-voltage battery. As a result, the battery modules could overheat and short circuit.  

Safety Risk: 
A short circuit in the high-voltage battery can create a fire risk.  

Corrective Actions: 
To reduce the safety risk, Mercedes-Benz recommends that you set the maximum charge setting of your vehicle at 80% until the recall repairs are completed. Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to update the battery management system software.

Issue: 
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.  

Corrective Actions: 
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.
