Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

report

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.
