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.

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.
