This page covers 4 recalls and 48 owner complaints for the 2016 Mercedes-Benz Gla 250.
Engine-related complaints lead the 2016 GLA 250 complaint set, followed by airbag and visibility concerns. On the engine side, owners report fault codes tied to the crankcase ventilation system, typically surfacing around higher mileage. Airbag complaints center on the warning light activating unexpectedly, several owners note that when the airbag light comes on, the horn stops functioning as well, which they describe as a separate but linked problem. A handful of owners report the instrument cluster behaving erratically: warning lights cycling on and off without apparent cause, gauge needles moving unpredictably, and the display dimming or going dark entirely. Visibility complaints involve the panoramic sunroof, where owners describe the glass tilting and jamming due to what they report as track or guide failures, sometimes accompanied by water getting into the cabin.

By System
The 2016 Mercedes-Benz GLA 250 has 4 recalls, the most serious being a driver's airbag that can deploy without warning, raising the risk of injury and a crash.
Two recalls involve the front roof panel, the section between the windshield and the panoramic sunroof. The adhesive bonding that holds this panel can deteriorate or, in cases where a prior repair was performed, may not have been bonded correctly the second time around. Either way, the panel can detach from the vehicle and become a hazard for other drivers on the road. There is also a software issue affecting the emergency call system, where the system's internal clock can fall out of sync with the actual date and time, causing it to report an inaccurate vehicle location to emergency responders if a call is triggered.
