2024 Mercedes-Benz GLC 300 4MATIC recalls (3)
Tap a recall to see the problem, the risk and the fix.
Latches/locks/linkages:doors:lock
Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2020-2021 CLA, 2019-2022 A-Class, 2022-2023 C-Class, 2024 CLE, 2020-2026 GLA/GLB, and 2023-2024 GLC vehicles. Please refer to MBUSA's recall report for specific model information. The micro-switch in the driver's door lock may corrode and fail to detect an open door, preventing the electronic parking brake or "Auto-Park" feature from engaging automatically. This may result in a vehicle rollaway.
Risk: A vehicle rollaway increases the risk of a crash or injury.
Fix: Dealers will replace the driver's door lock, free of charge. Owner notification letters are expected to be mailed September 18, 2026. This will be a phased campaign, with the remedy becoming available in different phases based on model and model years. Owners may contact MBUSA customer service at 1-800-367-6372. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning July 31, 2026.
Steering:critical fasteners
Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023-2026 EQE and GLC vehicles. Please see the recall report for a complete list of models. The steering coupling bolt may have been improperly tightened, allowing the steering coupling to loosen from the steering rack.
Risk: A loose steering coupling can cause a loss of steering control, increasing the risk of a crash.
Fix: Dealers will tighten the steering coupling bolts as necessary, free of charge. Owner notification letters were mailed October 6, 2025. Owners may contact MBUSA customer service at 1-800-367-6372.
Structure:body:roof and pillars
Problem: 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.
