What's wrong?
The driver-side seat belt tensioner on the 2022-2025 Mercedes-Benz C 300 and AMG C43 is part of the front seat belt system. The tensioner helps keep the belt tight when the restraint system needs to hold the driver in place, and the seat belt anchor relies on that assembly staying secure.
On affected vehicles, the cover on the driver seat belt tensioner was not installed correctly during plant rework. That incorrect cover position can let the seat belt anchor come loose. If the anchor loosens, the belt no longer stays fixed in the way Mercedes-Benz designed it to work.
There is no warning sign before failure. The driver will not get an advance warning from the vehicle because of how this failure happens, so the VIN check is what confirms whether this specific recall applies.

- Check your VIN to confirm your 2022-2025 Mercedes-Benz C 300 or AMG C43 is included in this recall.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the driver-side seat belt cover on the seat belt tensioner and repairs the cover if it is not installed correctly. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
