What can fail
The front roof panel between the windshield and panoramic sunroof may have been improperly bonded during a prior repair, causing the panel to detach from the vehicle.
What the fix does
The 2015 Mercedes-Benz AMG CLA45 has 5 recalls, the most serious being a roof panel that can detach from the vehicle while driving and a driver airbag that can deploy without warning.
The roof panel issue appears in two related recalls. The front panel between the windshield and panoramic sunroof may not be bonded securely to the vehicle, and if it lets go at speed it becomes a road hazard for other drivers. Prior repair attempts may not have fully resolved this bond, which is why the issue spans more than one filing. The driver airbag recall involves inadvertent deployment, meaning the bag can fire without a crash occurring, which raises the risk of injury and loss of vehicle control. On the engine side, a starting current limiter can overheat and melt the components around it, creating a fire risk under the hood. There is also a software fault in the emergency call system where an incorrect date and time can cause the system to relay an inaccurate vehicle location to emergency responders, potentially slowing their response if the car is ever in a crash.
