The 2011 Mercedes-Benz C63 has 2 recalls, both involving Takata airbag inflators that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death to the driver or passengers.
Both the driver and front passenger frontal airbag inflators are affected. If either airbag deploys in a crash, the inflator housing can burst and scatter metal shrapnel through the interior. These recalls are part of the well-documented Takata airbag issue and prior repair attempts may not have fully resolved the problem for all vehicles, so confirming your specific VIN is repaired remains worthwhile.
