Mercedes-Benz GLC 300 Recall 18V838: Passenger Airbag Status Light May Show Wrong Status

NHTSA campaign 18V838, reported November 27, 2018, 104,663 vehicles potentially affected.

What this recall means for you

The infotainment (audio) head unit in these vehicles may incorrectly display the front passenger airbag as "ON" when it is actually off, or the status may not display correctly at all. The problem affects vehicles equipped with the Audio 20 head unit and automatic child seat recognition.

The danger is that a front seat passenger may believe the airbag will deploy in a crash when it will not. That false sense of protection could increase the risk of injury to the passenger if a collision occurs.

Mercedes-Benz USA will notify owners, and authorized dealers will update the audio head unit software at no charge. The recall began January 3, 2019. Owners can contact MBUSA customer service at 1-800-367-6372, referencing recall number 2018120009. You can also check your VIN for open recalls.
