Plain-English summary

Mercedes-Benz USA, LLC is recalling certain 2014-2020 model year vehicles, including the C 300, S 450, C 350 E, and CLA 250, among others, that are equipped with a panoramic sunroof. The recall involves 15,096 vehicles where the front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair.

The adhesive bonding of the front panel might deteriorate, which could cause the front panel to detach from the vehicle. A detached panel could become a road hazard, increasing the risk of a crash. The source text does not report any specific injuries or fatalities associated with this defect.

Mercedes-Benz dealers will remove the bonded panel and install a new front panel following detailed repair instructions and using approved primer, cleaner, and adhesive, free of charge. Owner notification letters were mailed on September 3, 2021, and October 26, 2021. Owners may contact MBUSA customer service at 1-800-367-6372 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
