Electrical System Jun 14, 2018
Report Receipt Date:
Jun 14, 2018
NHTSA Campaign:
18V407000
Summary:
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2018 Mercedes-Maybach S560 and S560 4Matic and Mercedes S450 4Matic, S450, S560, S560 4Matic, and S560 Coupe 4Matic vehicles. The electrical power bars inside the pre-fuse box in the trunk may not have been secured properly.
Consequence:
If the power bars are not properly secured, it can cause higher electrical resistance increasing the risk of a fire. Additionally, an intermittent contact between the power bars could lead to a loss of vehicle functions. The engine operation, the seat belt functions and the instrument cluster could be impaired, increasing the risk of a crash and injuries.
Remedy:
MBUSA will notify owners, and dealers will inspect the pre-fuse box, replacing it as necessary, free of charge. The recall began August 30, 2018. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2018080001.

Report Receipt Date:
Dec 17, 2017
NHTSA Campaign:
17V816000
Summary:
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. The rear passenger door on the driver side may indicate that it is locked, when it may not be. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 206, "Door Locks and Door Retention Components."
Consequence:
If the door appears to be locked, the door may be unintentionally opened, increasing the risk of injury.
Remedy:
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.
