What the defect is
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017-2019 C300, E300, 2018-2020 CLA250, 2020 CLS450, AMG E53, AMG GT53, GLE450, 2018 AMG E63, AMG GTA, 2017-2020 GLA250, GLC300, 2019 GLC350, AMG GLC43, 2017-2018 GLE350, 2019 AMG GLC 43, GLC350, GLE400, 2017 GLS450, S550, C300 Cabrio, and 2018-2019 S560 vehicles. On June 18, 2021, an additional 9 vehicles were added, including certain 2021 GLA250, GLC300, 2018 S450, E400, and 2017 CLA250 vehicles. The communication module might have been inadvertently deactivated during a service visit, which could have disabled the Emergency Call (eCall) function.
What could happen
A disabled eCall system would prevent a vehicle occupant from contacting emergency services through the call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.
What gets fixed
MBUSA will notify owners, and dealers will inspect the communication module and activate it, if necessary, free of charge. The recall began March 31, 2021. Letters for the owners of the 9 additional vehicles were mailed July 9, 2021.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 12 February 2021.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
