NHTSA recall 18V912000
Air Bags, Visibility · Mercedes-Benz USA, LLC
Details
What's wrong: The sunroof bonding may allow water to leak into the vehicle.
Why it matters: Water leaking into the vehicle from around the sunroof may affect the electrical contacts of the window air bag, potentially causing the window air bag to not deploy as intended, increasing the risk of injury in the event of a crash.
The fix: Mercedes has notified owners, and dealers will inspect the bonding of the panorama sliding sunroof and the electrical contacts of the window air bag on the affected vehicles, replacing the components as necessary, free of charge. The recall began April 12, 2019.
