Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017 GLE400 4Matic, GLE350 4Matic, GLE350, GLE550e 4Matic, GLE43 AMG 4Matic, GLE63 AMG 4Matic, GLS450, GLE63S 4Matic, GLS63 4Matic, S550e, S600, S63 AMG 4Matic, S65 AMG, S550, Mercedes-Maybach S600, Mercedes-Maybach S550 4Matic, GLE43 AMG 4Matic Coupe, GLE63S 4Matic Coupe, 2017-2018 GLS550 4Matic, S550 4Matic, 2018 S450, and S63 AMG 4Matic vehicles.

Fix: MBUSA will notify owners, and dealers will inspect the left rear door lock, replacing it as necessary, free of charge. The recall is expected to begin in January 2018. Owners may contact MBUSA customer service at 1-877-496-3691.

Recalls come from the National Highway Traffic Safety Administration's recall database, with the list of models updated October 7, 2026. A recall applies to some vehicles of a model year, not always all of them: your VIN tells you whether yours is included and if the free repair has been done.
