2023 Mercedes-Benz G 550 problems

24V659000

Date: 2024-09-09. Systems: LATCHES/LOCKS/LINKAGES.

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. Components within the right-side rear door latch may prevent the rear doors from latching or opening properly.

Consequence: The rear door may appear closed even when the latch is not fully engaged, allowing the door to open while driving and increasing the risk of injury or a crash. Damaged latch components may prevent the rear door from being opened while inside the vehicle, increasing the risk of injury.

Remedy: 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. Vehicles in this recall that were previously repaired under recall 21V-353 will need to have the new remedy completed.

Do not drive: No. Park outside: No.
