Recall 20V673 covers 2019-2021 Mercedes-Benz E 350, E 450, AMG E53, and AMG E63 vehicles for a passenger-seat range-stop defect. Free dealer repair.
Mercedes-Benz is recalling 1,337 2019-2021 vehicles, including the E 350, E 450, AMG E53, E63 AMG, and AMG E63, because the front passenger seat can lack a mechanical range limit stop. If the seat moves beyond the acceptable range in relation to the air bag, crash injury risk increases during air bag deployment, and Mercedes-Benz dealers will complete the free repair.

What's wrong?
The front passenger seat in these 2019-2021 Mercedes-Benz E 350, E63 AMG, AMG E53, E 450, and AMG E63 vehicles uses a mechanical range limit stop. That stop is a physical limiter in the seat track. It keeps the seat from sliding past the position Mercedes-Benz designed for correct spacing between the passenger and the air bag.
On affected vehicles, the limiter was not installed during a certain production period because a manual installation step did not follow the work instruction. Without the limiter, the front passenger seat can move beyond the approved range. That changes the passenger's position relative to the air bag, so the restraint system is not working from the seating position it was designed around.
There is no warning sign before failure. The seat can still adjust, and the missing limiter is not something an owner is expected to detect during normal use.
Who's affected?
Covers five Mercedes-Benz model variants from 2019-2021, all tied to the seat assembly.

What's the safety risk?
If the front passenger seat moves beyond the approved range, the passenger can sit too far out of position for the air bag. That raises injury risk in a crash with air bag deployment. There is no advance warning before this problem. Schedule the inspection and repair soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2019-2021 Mercedes-Benz E 350, E63 AMG, AMG E53, E 450, or AMG E63 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free front passenger seat inspection.
- Schedule the seat range-limit-stop installation if the dealer finds it missing, which keeps the passenger seat from moving outside the acceptable air bag range.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 20V673 and Mercedes-Benz recall 2020110013 when you call.
- Avoid placing the front passenger seat at the far end of its travel until the dealer completes the inspection and repair.
- Call Mercedes-Benz customer service at 1-800-368-6372 with questions about the recall or dealer appointment.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front passenger seat for the mechanical adjustment range limit stop and installs the stop if it is missing. The inspection and any needed installation are free under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty and were not previously subject to this condition. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
