25V379000Body & StructureJune 6, 2025 · 92,851 units

Defect

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.

Consequence

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

Remedy

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.
