What's wrong?
The front passenger power seat in the 2018 Mercedes-Benz AMG E63S is supposed to move only within a defined travel range. That range matters because the seat position works with the air bag, belt, and vehicle structure during a crash. The seat control unit and the mechanical stops are the parts that keep the seat from moving past that intended limit.
On affected vehicles, the mechanical limit and seat software calibration do not restrict the front passenger seat to the current production specification. The seat can adjust farther than Mercedes-Benz intended. That places the passenger seat outside the tested range used during internal certification crash testing, which is why the seat needs an update and corrected adjustment limits.
There is no warning sign before failure. The passenger seat can still power forward and back, so an owner is not given a warning light, sound, or obvious change that confirms the travel range is wrong.

What's the safety risk?
If the passenger seat moves beyond its intended adjustment range, the occupant faces a higher risk of injury in a crash. There is no warning sign before this seat adjustment problem, so avoid forcing the seat past normal travel and schedule the recall repair soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2018 Mercedes-Benz AMG E63S is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free front-passenger-seat adjustment-range inspection and repair that keeps the seat within its intended travel.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 18V609 when you call.
- Avoid using the front passenger seat at the far end of its adjustment travel until the dealer completes the repair.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front passenger seat adjustment range. If the seat moves beyond its intended limit, the technician installs a mechanical adjustment range limiter or updates the seat control unit software. The inspection and any recall repair are free. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because all involved vehicles remain under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
