The 2017 Mercedes-Benz C350e has 4 recalls, the most serious being a roof panel that can detach from the vehicle and land in the path of other traffic, and a driver airbag that can deploy without warning.
The roof panel issue appears in two related recalls: the adhesive bonding the front panel between the windshield and panoramic sunroof can fail, allowing the panel to separate at speed and become a road hazard. A prior repair attempt to address this bonding problem may not have fully resolved the issue, which is why a second recall covering the same panel exists. The airbag concern is separate: the driver airbag can fire on its own without any crash occurring, raising the risk of injury and loss of vehicle control. There is also an issue with the automatic crash notification system, known as eCall, which contacts emergency services after a collision. If it malfunctions, responders may be sent to the wrong location, delaying help when it is most needed.
