Mercedes-Benz emergency call system may report wrong crash location

NHTSA campaign 21V058000 · Reported 2021-02-05 · Mercedes-Benz USA, LLC

medium How serious is it? About this label

Failure of the eCall system may result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash. The notice does not tell owners to stop driving.

What's wrong, in plain English

These Mercedes-Benz vehicles have a built-in system that automatically calls for help after a crash. Because of a software flaw in the car's communication unit, that call may send the wrong location. Emergency crews could then be sent to the wrong place, delaying help for you or your passengers. The car itself drives normally; only the emergency call feature is affected. The fix is updated software, installed by a dealer or sent to your car over the air.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to check whether your vehicle is included. 2. Contact Mercedes-Benz customer service at 1-877-762-8267 or your dealer about recall 2021020025. 3. Accept the over-the-air update or have the dealer install it free of charge.
