2017 Mercedes-Benz GLC

Issue: 
On certain vehicles, the plastic panel located between the windshield and the panoramic sunroof may not have been attached correctly during a prior service repair. Over time, the panel could loosen and separate from the vehicle. 
Note: This is an expansion of Transport Canada recall 2021-170. 

Safety Risk: 
A panel that detaches from a moving vehicle could create a road hazard for others and 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 replace the front roof panel.

Issue: 
On certain vehicles, the rear-side glass may not be properly marked with its safety rating. Canadian regulations require a marking to identify the type of glass that is used. 

Safety Risk: 
This error is unlikely to affect safety. 

Corrective Action: 
This is not a recall. This notice is for information only. The company has made changes to ensure that all new vehicles have glass that is marked correctly.

On certain vehicles originally sold or currently registered in areas of heavy road salt usage during winter months (Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador), the bolts that attach the electric power steering assist motor to the steering gear housing may corrode and break. This could cause a loss of power steering assist. The resulting increase in steering effort could create the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the mounting bolts and apply a corrosion protection coating to the gear housing and bolts. If the bolts bolt cannot be removed, a replacement steering gear will be installed.

On certain vehicles, the seat belt latch plate in the second seating row outboard seats might retract into the area between the C-pillar paneling and the rear side paneling. This could hinder the access to the seat belt latch plate for the outboard seat occupants. If a rear seat passenger does not fasten the seat belt, the risk of injury in the event of a crash could increase. Correction: Dealers will add a buffer element to the C-pillar paneling. Note: This is an expansion of recall 2018-136.
