The 2017 Mercedes-Benz GLC Class has 3 recalls, the most serious involving front seatbelt pretensioners that may fail to tighten the belt in a crash, leaving occupants less restrained at the moment of impact.
The panoramic sunroof is the subject of a separate concern: the frontal and side glass panels may not be properly bonded to the vehicle and can detach while driving, sending glass onto the road and posing a hazard to other vehicles and pedestrians nearby. The third recall is a compliance issue involving the rear side windows, which may lack the required safety rating markings on the glass. This does not affect how the glass performs but means the vehicle does not meet Canadian labeling regulations.
