The 2015 Mercedes-Benz CLA250 has 7 recalls, the most serious being an inadvertent driver airbag deployment that raises the risk of injury and loss of vehicle control.
The passenger airbag system also has a concern: the seat's occupant classification sensor may be miscalibrated, causing the front passenger airbag to fail to deploy in a crash. On the structural side, the front 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 this issue for some vehicles, which is why two separate campaigns exist for this defect. The engine on certain vehicles built in a narrow window during the summer of 2015 has camshaft welds that can fail and cause engine damage, potentially leading to a stall. There is also an electrical concern where the starting current limiter can overheat and melt surrounding components, raising the risk of a fire. Finally, a software fault in the emergency call system can report an inaccurate vehicle location to first responders, which may delay help in an emergency.
