Plain-English summary
Mercedes-Benz USA, LLC is recalling certain 2019-2025 CLS 53 4MATIC, E 53 4MATIC (Cabriolet, Coupe, and Sedan), GT 43 4MATIC, and GT 53 4MATIC vehicles. Approximately 22,422 vehicles are affected.
The transmission wiring harness connection may not have been correctly wired during a prior recall repair or during production. This improper wiring can expose the electrical connector to corrosion, which can result in an electrical short-circuit and increase the risk of a fire.
Dealers will replace the two-part wiring harness and connector free of charge. Mercedes-Benz USA notified owners of the safety risk via interim letter on August 9, 2024. A second notice will be sent once the final remedy is available. Owners should contact MBUSA customer service at 1-877-496-3691 for information about scheduling repairs. This recall supersedes recall 22V-533; vehicles previously repaired under that recall will still require the new remedy.
