Defect: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2019-2023 G 550 and 2019-2022 G63 AMG vehicles that received a replacement door latch during a service visit or prior recall repair.

Fix: Dealers will replace the right-side rear door latches, free of charge. Owner notification letters were mailed October 11, 2024. Owners may contact MBUSA customer service at 1-800-367-6372.
