    Remedy: Dealers will update the infotainment control unit software, free of charge. Owner notification letters were mailed June 29, 2026. MBUSA's number for this recall is 2026050004. 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 May 8, 2026.

    Steering:critical fasteners

    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.
