STRUCTURE:BODY:ROOF AND PILLARS06/06/2025

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023-2025 GLC 300, GLC 300 4MATIC, 2024-2025 AMG GLC 43 4MATIC, 2025 GLC 350E 4MATIC, and AMG GLC 63 S E vehicles equipped with a panoramic sunroof. In certain crash scenarios, where the rear occupant's head contacts the C-pillar, the pillar may not absorb an adequate amount of the impact. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 201, "Occupant Protection in Interior Impact."

Risk: In the event of a crash, insufficient impact protection can increase the risk of injury.

Fix: Dealers will modify the roof lining and C-pillar trim, free of charge. Owner notification letters were mailed July 9, 2025. Owners may contact MBUSA customer service at 1-800-367-6372.
