What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 Mercedes-Benz GLA 250, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
I am writing to formally submit an urgent safety escalation and Lemon Law notice regarding my 2026 GLA 250, purchased brand new on February 26, 2026, as a replacement vehicle following the severe operational disruptions associated with the EQB 300 recall. As a parent of a family member with a disability, reliable and secure transportation is an absolute necessity. I selected the Mercedes-Benz brand based on its reputation for engineering integrity and safety. Regrettably, the vehicle delivered has proven to be mechanically hazardous and operationally compromised. Since taking delivery, the vehicle has experienced the following recurring, catastrophic failures: • Multiple recurrent check engine warnings. • Three separate instances of complete failure to shift while actively operating in traffic. • Four complete starting failures accompanied by a permanent black screen. • Two total blackouts of the entire instrument cluster, odometers, and operational systems while in motion, with the most recent occurrence taking place on September 4, 2026.
