Defect
On certain vehicles, the sunroof glass may not be properly attached to the sliding roof frame. Over time, the glass can become loose and could separate from the vehicle. Note: Vehicles that were inspected under Transport Canada recalls 2019-668 and 2021-478 also require this inspection.
Safety Risk
A sunroof that detaches from the vehicle could create a road hazard for others and increase the risk of a crash.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the bonding of the sunroof glass. Dealers will replace the sliding roof, if necessary.
