What's wrong?
The panoramic sliding sunroof on the 2018-2019 Mercedes-Benz Gla 250 uses bonded joints to seal the roof opening to the body. The bond holds the glass and frame in place and keeps rainwater out of the cabin. That seal also helps protect nearby air bag components from moisture.
On affected vehicles, the sunroof bonding was not completed to current production specifications. The bond does not seal the roof opening as designed, so water can leak into the vehicle during rain or washing. Mercedes-Benz traced the concern to moisture reaching the window bag area, where the side curtain air bag system is located.
The warning sign is an air bag warning lamp in the instrument cluster. If that lamp turns on, the window bag system has detected a fault, and the vehicle needs dealer inspection before the problem is treated as fixed.
Who's affected?
Both model years include the same two areas of concern: the side air bag and the sunroof assembly.
| 2018 Mercedes-Benz Gla 250 | side air bag |
|---|---|
| 2018 Mercedes-Benz Gla 250 | visibility component |
| 2019 Mercedes-Benz Gla 250 | side air bag |
| 2019 Mercedes-Benz Gla 250 | visibility component |
| Units affected | 13 |
| Field incidents | NHTSA has logged no field incidents to date. |
A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
Water leaking around the sunroof can affect the window air bag electrical contacts. If that happens, the window air bag can fail to deploy as intended, increasing injury risk in a crash. A warning lamp in the instrument cluster alerts the driver to an impaired window air bag system. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2018-2019 Mercedes-Benz Gla 250 is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the free sunroof-bonding and window air bag electrical-contact inspection that addresses water leaks around the sunroof.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 18V912 when you call.
- Ask the dealer whether the sunroof bonding, window air bag contacts, or both need replacement after the inspection.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the bonding on the panorama sliding sunroof and checks the electrical contacts for the window air bag. If either part does not meet the recall requirements, the technician replaces the affected components. Parts and labor are covered under the recall. Out-of-pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, since all involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
