The 2017 Mercedes-Benz GLC Class has 3 recalls, the most serious involving the panoramic sunroof panels, which may not be properly bonded and can separate from the vehicle while driving, creating a hazard for other road users.
The seatbelt system also has a concern: front seatbelt pretensioners on certain vehicles may not meet specifications and can fail to tighten the belt in a crash, reducing restraint when it matters most. The third recall is a compliance issue involving the rear side glass, which may be missing the required safety rating markings. This labeling gap is not expected to affect how the glass performs.
