What's wrong?
The adjustable front passenger seat in the 2021 Mercedes-Benz Metris sits on a seat frame base and adjuster. That base anchors the seat to the van and holds the passenger in the intended position while the seat is adjusted and while the vehicle is moving. The welds on the frame base are the metal joints that keep that structure together.
On affected Metris vans, the front passenger seat frame base was not welded properly. A supplier welding machine was mounted incorrectly after maintenance, which changed the welding process and left certain weld seams outside specification. If the vehicle is in a crash, the seat frame base can lose stability and the passenger seat can move differently than Mercedes-Benz intended.
There is no warning sign before failure. The problem is inside the seat frame base, so an owner is not expected to feel, hear, or see a clear symptom during normal use.

What's the safety risk?
The safety concern is seat stability in a crash. An improperly welded seat frame base has less support than intended, increasing the risk of injury to the occupant during a collision. There is no listed warning sign before a crash exposes the problem. Repair is free at any franchised Mercedes-Benz dealer.

What happens at the repair
At the dealer, a Mercedes-Benz technician replaces the front passenger seat frame base covered by recall 21V106. The seat base is the structure under the adjustable front passenger seat, and this campaign covers replacement when the weld did not meet the required specification. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, since all involved vehicles remained covered by that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
