This page covers 11 recalls and 28 owner complaints for the 2019 Mercedes-Benz Gla 250.
The dominant complaint pattern for the 2019 Mercedes-Benz GLA 250 centers on the transmission and powertrain. Owners frequently report the transmission unexpectedly dropping into neutral while driving, cutting power to the wheels mid-trip. This happens across a range of speeds and is typically accompanied by a check engine light or a "See Dealer" message on the instrument cluster. Restarting the vehicle often restores normal operation temporarily, but dealerships have reportedly had difficulty reproducing or diagnosing the problem. A smaller group of owners describes a fuel odor both inside and outside the cabin while the vehicle is running, with no clear source identified. Airbag warning lights showing up without an obvious trigger account for a handful of additional reports.

By System
The 2019 Mercedes-Benz GLA 250 has 11 recalls, the most serious being a transmission control unit power interruption that can cause the vehicle to drop into neutral without warning, cutting drive power and raising the risk of a crash.
Several recalls involve structural and fire concerns. Fuel injector seals can develop a leak near hot engine components, creating a fire risk. Separately, a front roof panel can lose its adhesive bond and detach from the vehicle at speed, becoming a road hazard. One recall covers vehicles where a prior repair attempt to re-bond that panel may not have fully resolved the separation risk. An engine compartment fuse box that works loose over time can disrupt power steering, electronic stability control, and automatic emergency braking.
On the occupant safety side, a loose anchor plate on the rear center seatbelt can leave that position unsecured in a crash, and a sunroof that allows water intrusion can corrode the window airbag's electrical contacts, preventing deployment. Rear seat covering material may block the child seat tether anchor at the rear center position, making it impossible to secure a child seat there correctly.
Three related recalls cover the automatic emergency call system, which can either fail to connect, send responders to the wrong location, or go entirely offline after a crash.
