Mercedes-Benz C 300 and and 2023-2024 AMG C 43 recall: The driver-side seat belt cover may not be properly installed on the seat

Recall published 1+ years ago

The driver-side seat belt cover may not be properly installed on the seat belt tensioner, which can cause the seat belt anchor to come loose.

The hazard: Seat belt or seat defect

This campaign is about the restraint system — the belts, buckles, anchorages or seat frames that only do their job once.

What the notice says: A loose seat belt may not properly restrain an occupant during a crash, increasing the risk of injury.

Why it matters: A seat belt, buckle, anchorage or seat frame may not restrain an occupant properly in a crash. The fault is invisible in normal driving because the part is never loaded until it is needed.

What to do about Seat belt

Mercedes-Benz — This campaign is about the restraint system — the belts, buckles, anchorages or seat frames that only do their job once.

  1. Check every belt and seat in the vehicle for the symptom the notice describes, including the ones nobody usually sits in.
  2. Keep the repair order the dealer hands you. It is your proof the campaign was closed out, and it matters at resale.
  3. Check your own VIN at nhtsa.gov/recalls before you do anything else. A campaign covers a build range, not every car of that model year, and the VIN lookup is the only thing that confirms yours is included.
  4. Call any franchised dealer for the brand, give them the campaign number from this page, and ask them to confirm parts are in stock before you book — part supply, not labour, is what delays a fresh recall.

Costs, reimbursement and your rights

The repair itself is free. What people most often miss is that money already spent can frequently be claimed back.

  • If you paid for the same repair out of pocket before the recall was announced, ask the manufacturer for reimbursement. Carmakers must run a reimbursement plan for pre-notification repairs; you will need the original invoice.
  • A dealer may not charge a diagnostic, inspection or shop-supplies fee for recall work. If one appears on the estimate, query it before you sign.
  • If a dealer refuses the repair, delays it unreasonably or tries to bill you, complain to the manufacturer’s customer line, then to NHTSA. Those complaints are logged against the campaign.
  • An unrepaired open recall can affect a sale or trade-in. Closing it out costs nothing and protects the value of the vehicle.

Remedy named in the notice: Dealers will inspect and repair the seat belt covers, as necessary, free of charge. Owner notification letters were mailed May 16, 2025. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2025040012.
