Mercedes-Benz AMG E53 trunk battery may come loose in crash

NHTSA campaign 22V733000 · Reported 2022-09-30 · Mercedes-Benz USA, LLC

medium How serious is it? About this label

The inability to operate safety features (eCall system, hazard lights, electric seats, or automatic door locks) can increase the risk of injury during a crash. The notice does not tell owners to stop driving.

What's wrong, in plain English

The 12-volt battery in the trunk may not be bolted down tightly. In a crash it could move and break its electrical connections. If that happens, several things that help you afterward may stop working: the automatic emergency call that dials for help, the hazard flashers, the power seat controls, and the doors that unlock by themselves. The car drives normally otherwise. A dealer will secure the battery properly.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your car is included. 2. Contact a Mercedes-Benz dealer about recall 2022100009, or call MBUSA at 1-800-367-6372. 3. Have the 12-volt battery secured — the repair is free.
