What's wrong?
The second row seat track in the 2020 Mercedes-Benz Glb 250 is the metal rail system that lets the rear seat slide and lock at a chosen position. When it is aligned correctly, the latch engages the track so the seat stays fixed while passengers sit in it and while the vehicle moves.
On affected vehicles, the seat was not aligned correctly in the track on one side during installation. The locking mechanism for that track was displaced during production before the seat track was permanently attached to the vehicle. As a result, one side of the second row seat can fail to lock fully into place.
There is no warning sign before failure. An owner cannot count on a noise, warning light, or visible change to tell them that the seat track has not locked correctly.

What should I do?

- Contact a franchised Mercedes-Benz dealer to schedule the free inspection and correction for the second row seat track, so the seat locks in place.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the second row seat installation and corrects the seat alignment or seat track fit as needed so the seat locks properly into place. The recall repair is free, with parts and labor covered. Out of pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, since the involved vehicles remained under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
