Defect

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2024-2026 AMG GT, C-Class, E-Class, SL, CLE, and GLC vehicles. The infotainment control unit may reset while the vehicle is in motion and cause the instrument panel display to go blank.

Consequence

An instrument panel display that fails to show critical safety information, such as the speedometer and warning lights, increases the risk of a crash.

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.
