The 2010 Mercedes-Benz E550 has 3 recalls, all involving Takata airbag inflators that can explode and send metal fragments into the cabin, posing a risk of serious injury or death to the driver or passengers.
Both the driver-side and front passenger-side frontal airbag inflators are affected. In a crash that triggers airbag deployment, the inflator canister can rupture rather than inflate the bag normally, scattering sharp metal shrapnel through the interior. This is the same defect class that prompted one of the largest automotive recalls in history, and prior repair attempts on some vehicles did not fully resolve the issue, which is why multiple recall campaigns exist for what is essentially the same problem on both sides of the front seat. Any owner who has not yet had the airbag inflators replaced should treat this as a priority, as the risk is present any time the vehicle is involved in a collision serious enough to trigger deployment.
