The 2017 Mercedes-Benz AMG CLA45 has 7 recalls, the most serious including a driver airbag that can deploy without warning and a steering shaft universal joint that can separate and cause a complete loss of steering control.
The roof panel between the windshield and panoramic sunroof can detach from the vehicle and become a road hazard; prior repair attempts did not fully resolve the issue for some vehicles, and a separate recall addresses the original bonding defect. On the engine side, a starting current limiter can overheat and melt surrounding components, raising the risk of a fire. The passenger seat occupant classification sensor may have been incorrectly calibrated, which can prevent the front passenger airbag from deploying in a crash. There is also a concern with the automatic crash notification system: if the vehicle is involved in a collision, the eCall system may send emergency responders to the wrong location.
