What's wrong?
The front seat belts in the 2015 Mercedes-Benz AMG S63, AMG S65, and S550 4MATIC are built as side-specific restraint parts. Each belt routes across the occupant at a set angle, then locks during a sharp stop or crash so the belt can hold the person in the proper position.
In the recalled vehicles, the left and right front seat belts were installed on the opposite sides during assembly. The belts fit in both positions, but the angle is wrong when they are swapped. That incorrect angle affects the locking behavior, and the passenger-side child seat restraint function is not available.
There is no warning sign before failure. The belt can look normal from the seat, so an owner is unlikely to notice the swapped installation without an inspection or dealer repair.

What's the safety risk?

What should I do?
- Check your VIN to confirm your 2015 Mercedes-Benz AMG S63, AMG S65, or S550 4MATIC is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free front-seat-belt inspection and correction for the left/right seat belt installation issue.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 15V657 when you call.
- Drive cautiously until the dealer checks the seat belts, and avoid placing a child restraint in the front passenger seat.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front seat belt installation and checks whether the left and right side belts were installed on the correct sides. If the belts are installed incorrectly, the technician corrects the installation so the locking behavior and passenger child restraint function work as designed. The recall repair is free, with parts and labor covered. Mercedes-Benz used its standard reimbursement plan for this campaign. If you already paid for a related seat belt repair before the recall notice, bring repair documentation to the service desk or contact Mercedes-Benz customer service to ask about reimbursement.
