What's wrong?
In 2018 Mercedes-Benz AMG E63S, AMG C63S, and AMG C43 vehicles fitted with AMG performance seats, the front seat backrest rail is part of the frame that supports the seatback. The rail and the metal fitting hold the seatback in position when the seat is adjusted and when loads move through the seat.
On affected vehicles, a supplier welding process left the backrest rail and metal fitting without the required weld strength. The problem traces to a certain batch of rails, not to every seat frame. If the weld is weak, the connection can loosen and let the seatback move more than designed.
An owner can notice increased play in the seatback or backrest rail. That means the seatback feels loose, shifts, or moves more than expected when pressure is applied. If your VIN is included, tell the Mercedes-Benz dealer that the concern is the front seat backrest rail weld under recall 18V150.
Who's affected?
Covers three AMG models in the 2018 model year, all tied to the same seat recliner component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific car is included.
What's the safety risk?
Incorrect welds in the seat backrest frame can let the seats fail in a crash, increasing injury risk. Increased play in the backrest rail is a warning sign. If your VIN is included, schedule the inspection soon and avoid using a loose-feeling seat until the dealer checks it. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2018 Mercedes-Benz AMG E63S, AMG C63S, or AMG C43 is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the free seat-backrest weld inspection and backrest replacement that fixes the improperly welded front-seat backrest frames.
- Bring the owner letter if Mercedes-Benz mailed one. If not, reference recall number 18V150 when you call.
- Ask the dealer whether your vehicle is safe to drive before the inspection, since the affected seats can fail in a crash.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the welds on the driver and front passenger seat backrest frames. If a weld defect is found, the technician replaces the affected backrest. Parts and labor are free under the recall. Mercedes-Benz's standard reimbursement plan covers documented out-of-pocket repairs tied to this condition before the recall notice. Bring repair invoices, payment records, and any dealer paperwork to the service desk so Mercedes-Benz can review the claim.
