The 2016 Mercedes-Benz CLA250 has 8 recalls, the most serious being an airbag that can deploy without warning while driving, raising the risk of a crash or injury.
Two other recalls affect airbag reliability in a crash. A software fault can prevent airbags from deploying correctly, and the passenger seat sensor may be miscalibrated so the front passenger airbag does not deploy as intended. On the structural side, the front roof panel between the windshield and panoramic sunroof can lose its adhesive bond and detach while driving, creating a road hazard for other vehicles. Prior repair attempts to address this bonding issue may not have fully resolved the problem, which is why a separate recall exists for vehicles that were already serviced. There is also a fire risk: an overheating starting current limiter can melt surrounding components under the hood. Finally, two related recalls cover the emergency call system, which can send inaccurate location data or dispatch responders to the wrong place after a crash, delaying emergency response.
