What's wrong?
The 12-volt battery in these 2019-2022 Mercedes-Benz E 450, AMG E53, AMG CLS53, and Cls 450 vehicles sits in the trunk and supplies electrical power when the car needs stored battery energy. Its mount is supposed to hold the battery in place so the electrical connections stay intact, including after crash forces.
In the recalled vehicles, the battery mount was built from an earlier design that does not meet current production specifications. Mercedes-Benz traced the issue to a development-process deviation, meaning the mount can fail under certain crash loading and allow the battery to move. If that movement breaks electrical connections, systems such as emergency call, electric seat adjustment, hazard warning lights, and automatic door locks can stop working when occupants need them after a crash.
There is no warning sign before failure. The driver would not receive a dashboard warning because the problem depends on crash forces acting on the battery mount.

What's the safety risk?
If the battery is not secured, eCall, hazard lights, electric seats, or automatic door locks can stop working when they are needed during a crash. That loss of safety features increases the risk of injury. There is no warning sign before the failure. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2019-2022 Mercedes-Benz E 450, AMG E53, AMG CLS53, or Cls 450 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free 12V battery securement repair that keeps the trunk battery from losing electrical connections in a crash.
- Bring the owner letter if you received one, and reference recall number 22V733 when you call.
- Drive cautiously until the repair is complete, since the recall involves safety features such as eCall, hazard lights, electric seat adjustment, and automatic door locks.
What happens at the repair
At the dealer, a Mercedes-Benz technician secures the 12V battery in the trunk so it stays properly mounted during a crash. The recall repair is free, and parts and labor are covered. If you've already paid out of pocket for a related battery securement repair, Mercedes-Benz handles claims through the manufacturer's standard reimbursement plan. Bring repair invoices and proof of payment to the service desk, or contact MBUSA customer service for claim instructions.
