This page covers 9 recalls and 38 owner complaints for the 2018 Mercedes-Benz Cla 250.
Electrical complaints dominate what 2018 CLA 250 owners report, with the instrument cluster and dash electronics drawing the most attention. Owners describe the gauge cluster displaying inaccurate readings, lights flickering, and the entire dashboard cycling on and off while driving. A handful of reports describe a more complete electrical shutdown, where the instrument panel goes dark without warning. Airbag-related complaints make up the second-largest group, though the specific symptoms vary across those reports. On the engine side, a few owners describe sudden power loss and misfires, in at least one case connected to fuel system corrosion. A smaller number of owners report an audible clicking from the steering column during turns, sometimes paired with the steering wheel controls stopping working.

By System
The 2018 Mercedes-Benz CLA 250 has 9 recalls, the most serious being a driver airbag that can deploy without warning, raising the risk of injury and a crash.
Two separate recalls involve the front passenger seat sensor being miscalibrated: in one case, it may fail to deactivate the passenger airbag when a child seat is present, and in another, it may prevent the airbag from deploying correctly for an adult passenger. Both scenarios raise the risk of injury in a crash. On the structural side, the adhesive bonding on the front roof panel can deteriorate or fail, allowing the panel to detach from the vehicle and become a road hazard. One of these roof panel recalls applies where a prior repair attempt did not fully resolve the bonding issue.
Three recalls concern the emergency call system: in different scenarios, the system can become disabled entirely or dispatch responders to the wrong location, either of which delays emergency help after a crash. There is also a lighting issue where taillights and side marker lights can flicker or go dark, reducing the vehicle's visibility to other drivers.
