The problem
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2026 AMG GLC43 4MATIC, GLC 300 4MATIC, GLC 300, and GLC 300 4MATIC Coupe vehicles. The center rear seat belts may have been installed without the child seat protection function and fail to lock a child restraint properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection," and FMVSS number 209, "Seat Belt Assemblies."
The risk
In the event of a crash, an insufficiently restrained child has an increased risk of injury.
The fix
Dealers will inspect and replace the center rear seat belt assembly as necessary, free of charge. Owner notification letters were mailed May 15, 2026. 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 March 27, 2026.
