What's wrong?
The front seat wiring harness in 2019-2021 Mercedes-Benz Sprinter 1500, Sprinter 2500, Sprinter 3500, and Sprinter 4500 vans carries power and control signals for electric seat functions. On vans with electrically adjustable swivel seats, that wiring also sits near the seat frame and airbag wiring. It needs to stay clipped in the intended path as the seat moves and swivels.
On affected vans, the harness was routed or mounted outside specification. When the front swivel seat turns to its maximum rotation, the loose or misplaced wiring can get jammed in the swivel-seat frame. That pinching can damage the harness and interfere with the electrical circuits it supplies, including the side airbag circuit.
If the side airbag wiring is affected, the SRS indicator lamp will turn on and stay on until the condition is repaired. That warning light is the sign to report when calling the dealer.
Who's affected?
Covers Mercedes-Benz and Freightliner Sprinter 1500, 2500, 3500, and 4500 vans from 2019, 2020, and 2021, with the same front-seat wiring harness tied to front air bag and electrical-system components.

A matching Sprinter year and model does not confirm inclusion. Check your VIN to confirm whether your specific van is included.
What's the safety risk?
In NHTSA campaign 21V410, damaged seat wiring can cause the side air bag to deploy when it should not, or fail to deploy as designed, increasing injury risk. If the SRS indicator lamp stays on, call a Mercedes-Benz dealer for guidance. Repair will be free at any franchised Mercedes-Benz dealer once available.
What should I do?
- Check your VIN to confirm your 2019-2021 Mercedes-Benz Sprinter 1500, Sprinter 2500, Sprinter 3500, or Sprinter 4500 is included in this recall.
- Review the owner letter Mercedes-Benz mailed on August 11, 2021, or call Mercedes-Benz customer service at 1-877-762-8267 if you do not have the letter.
- Contact a franchised Mercedes-Benz dealer about the free mounting-clip repair that reroutes the front-seat wiring harness away from the swivel seat frame.
- Reference recall number 21V410 when you call, and bring the recall notice if you have it.
- Drive with care until the repair is complete because damaged seat wiring can affect side air bag deployment.
What happens at the repair
The repair described for this campaign is straightforward: once the remedy is available, a Mercedes-Benz technician attaches the seat wiring harness mounting clip in the correct position so the harness stays clear of the swivel seat frame. The dealer repair will be free once available, with parts and labor covered under the recall. Mercedes-Benz has a general reimbursement plan on file. If you already paid for a related wiring harness or swivel seat frame repair before the recall notice, ask Mercedes-Benz customer service or the service desk what documentation the plan requires.

Frequently asked questions
What is recall 21V410?
Recall 21V410 covers 4,078 2019-2021 Mercedes-Benz and Freightliner Sprinter vans equipped with swivel seats.

What should I do if my 2019-2021 Mercedes-Benz Sprinter 1500, Sprinter 2500, Sprinter 3500, or Sprinter 4500 is on this recall?
Check your VIN to confirm your specific van is included in recall 21V410. If it is, call a franchised Mercedes-Benz dealer and ask for recall VS3DREHSEL. The dealer will attach the mounting clip in the correct position free of charge.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. For recall 21V410, the dealer will attach the front-seat wiring-harness mounting clip in the correct position free of charge.
What is the safety risk?
The safety risk is improper side air bag deployment. If the front-seat wiring harness is damaged in the swivel seat frame, the side air bag within the seat can deploy when it should not, or fail to deploy as designed, increasing injury risk.
What if I bought my Sprinter used?
