Recall 18V5390009,044 vehicles

Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2018 Mercedes-Benz GLE350 4Matic, GLE350, GLS450 4Matic, GLS550 4matic, GLE43 AMG 4Matic, GLE63 AMG 4Matic, GLE63S AMG 4Matic, and GLS63 AMG 4Matic vehicles. The rear brake caliper pistons on these vehicles may not have been correctly coated, causing gas to become temporarily released into the rear brake hydraulic circuit, reducing braking performance.
Risk: Reduced braking performance can increase the risk of a crash.
Fix: MBUSA will notify owners, and dealers will bleed the rear axle brake system, free of charge. The recall began September 14, 2018. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2018080013.

Recall 17V8160008,700 vehicles

Problem: 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."
Risk: If the door appears to be locked, the door may be unintentionally opened, increasing the risk of injury.
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.
