What's wrong?
On the 2014 Mercedes-Benz SL550, SLK55, SL63, SLK250, SLK350, and SL65, the front passenger air bag is part of the supplemental restraint system. It sits inside the dashboard and is designed to inflate in a qualifying crash, cushioning the passenger and working with the seat belt to reduce injury.
Campaign 14V386 involves an air bag assembly error. Because of that error, the passenger air bag is not positioned or built as intended, so it can fail to deploy correctly when the crash sensors command it. The defect is in the air bag assembly itself, not something an owner can inspect from the outside.
There is no warning sign before failure. The vehicle can drive normally, and the passenger air bag can still be affected even if the dashboard shows no obvious air bag warning.
Who's affected?
Spans SL550, SLK55, SL63, SLK250, SLK350, and SL65 in the 2014 model year, all involving the air bag system.

What's the safety risk?
For an included 2014 Mercedes-Benz, a crash that requires front passenger air bag deployment can leave that air bag improperly deployed, increasing injury risk for the person in that seat. Keep passengers and items out of the front passenger seat until the repair is complete. Repair will be free at any franchised Mercedes-Benz dealer once available.
What should I do?
- Check your VIN to confirm your 2014 Mercedes-Benz SL550, SLK55, SL63, SLK250, SLK350, or SL65 is included in this recall.
- Look for the Mercedes-Benz owner letter mailed on August 18, 2014, and keep it with your service paperwork.
- Contact a franchised Mercedes-Benz dealer and ask about the free front passenger air bag replacement that fixes the improper passenger air bag deployment risk.
- Reference recall number 14V386 when you call the dealer.
- Keep passengers and items out of the front passenger seat until the repair is complete.
What happens at the repair
Mercedes-Benz's interim instruction is clear: until the recall repair is complete, keep passengers and loose items out of the front passenger seat. The dealer repair replaces the front passenger air bag assembly. Mercedes-Benz's filing says a second owner letter was mailed after parts became available in mid August 2014, and the replacement is free under the recall. At the dealer, a Mercedes-Benz technician removes the affected passenger air bag and installs the replacement part so the system can deploy as intended.
