The 2001 Mercedes-Benz C Class has 4 recalls, the most serious being a sunroof that can work loose over time and detach from the vehicle entirely, sending a large piece of glass onto the road and into traffic.
Prior repair attempts under earlier recall campaigns did not fully resolve the issue for some vehicles, and additional inspections are required to confirm whether the sunroof glass is properly secured to the sliding roof frame. Any vehicle that has had a sunroof installed or replaced as part of a previous repair may also be affected, not just those with the original factory-fitted unit. There is also a lighting concern: certain vehicles were fitted with an incorrect Signal Acquisition and Activation Module, which is the electronic control unit that manages various electrical functions including exterior lighting. As a result, the front side marker lights may not turn on when the headlight switch is activated, reducing the vehicle's visibility to other drivers in low-light conditions.
