Recall 17V654000

Rear Differential Mounting Fractures Causing Misalignment And Failure Of Driveshaft

Recall Details

The driveshaft may fail due to a fracture of the rear differential mounting flange which can occur due to repeated aggressive vehicle launches. Dealers will update the vehicle's stability system software and chassis control unit software free of charge to resolve the concern.

Our Quick Take

The rear differential mounting flange may fracture from repeated aggressive launches. This would cause the rear differential to become out of proper alignment and could result in the driveshaft failing. This could result in a crash.

What Should You Do?

If you do not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local Mercedes Benz dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with.
