The 2017 Mercedes-Benz CLA250 has 10 recalls, the most serious involving a driver airbag that can deploy without warning, raising the risk of injury and a crash.
Two structural recalls involve roof and body panels: the adhesive bonding on the front body panel can deteriorate and cause that panel to detach and become a road hazard, and the front roof panel between the windshield and panoramic sunroof can also come loose if it was not correctly bonded during a prior repair attempt. On the steering side, the universal joint bearing in the steering shaft can work loose over time and separate, causing loss of steering control. A starting current limiter can overheat and melt surrounding components, raising the risk of fire.
Several recalls concern occupant protection. The front passenger airbag inflator or pelvis airbag initiator can fail to fire in a crash, leaving occupants without intended protection. The passenger seat occupant classification sensor may be miscalibrated, which can also prevent the front passenger airbag from deploying correctly.
Three overlapping recalls cover the vehicle's automatic emergency call system, which can fail or direct responders to the wrong location in a crash, delaying help from reaching occupants.
