Recall history

3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

17V816000 · Latches/Locks/Linkages:Doors:Latch

Reported: 2017-12-18 (December 18, 2017)

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.

18V539000 · Service Brakes, Hydraulic

Reported: 2018-08-16 (August 16, 2018)

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.

Consequence: Reduced braking performance can increase the risk of a crash.

Remedy: 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.

21V058000 · Communication: Auto Crash Notification | Electrical System:Software

Reported: 2021-02-05 (February 5, 2021)

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 - 2021 CLA-Class, GLA-Class, GLE-Class, GLS-Class, SLC-Class, A-Class, GT-Class, C-Class, E-Class, S-Class, CLS-Class, SL-Class, B-Class, GLB-Class, GLC-Class, and G-Class vehicles. Please refer to the Part 573 report for specific vehicle model details. The software design of the communication module may fail to communicate the correct vehicle location for the emergency call system (eCall) in the event of a crash.

Consequence: Failure of the eCall system may result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.

Remedy: MBUSA will notify owners, and the communication module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. The recall began March 12, 2021. Owners may contact MBUSA customer service at 1-877-762-8267. MBUSA's number for this recall is 2021020025.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
