Mercedes-Benz GLA 250 stalling problems

Filed Oct 19, 2026 · Brakes, Driver assistance · FL

Vehicle: 2020 Mercedes-Benz GLA 250 VIN: [XXX] I am filing a safety complaint regarding a severe, recurring defect in the Electronic Parking Brake (EPB) and vehicle braking system. On three separate occasions, the vehicle has malfunctioned while driving, dangerously creating an imminent risk of an accident. Without warning, the vehicle acts as if the emergency parking brake has been manually engaged. Immediately following this event, multiple warning lights illuminate on the dashboard (including a warning stating "Active Brake Assist Functions Limited"). Once these lights appear, the braking system completely locks up the wheels, stalling the vehicle in place and making it entirely impossible to move. This failure has occurred in active traffic, leaving the vehicle stranded and creating a severe rear-end collision hazard. I have already paid over $2,000 in out-of-pocket repair costs attempting to diagnose and fix this issue at independent shops, but the dangerous malfunction continues to happen. I am aware of a recent XXX Mercedes-Benz safety recall concerning defective door latch microswitches causing identical electronic parking brake lockups on GLA models. However, when checking my specific VIN on the manufacturer's database, it states my vehicle is not included. Given that my vehicle exhibits the exact same life-threatening failure symptoms as the recalled population, I request that the federal safety agency investigate this issue to determine if the current recall scope needs to be expanded to include my vehicle's batch.

The vehicle experienced a sudden, total communication network crash on [XXX] the vehicle simultaneously triggered cascading critical safety system faults including “ inoperable” messages for the SOS system, Supplemental Restraint System ( SRS) and antilock brake system(ABS) along with check engine light on dashboard. The car locked itself in park and completely refuses to engage any drive gears. I took it to the dealer in Henderson, NV and they reported to me on Dec 24, 2025 that it will be a $1200 diagnostic and the repairs can be thousands of dollars. Since then I have taken it to 5 European and independent shops and have spent thousands of dollars for guess work. This happens sporadically I have been broken down where tow trucks have to retrieve my car and take to a shop where they have no clue of the issue. I am scared to drive it if it stalls on the streets and have a major accident. No problem has been resolved INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

To Whom It May Concern at the federal safety agency, I am submitting this complaint regarding the Mercedes-Benz GLA-Class vehicles equipped with the M274 engine, which have been unfairly excluded from recent recall campaigns affecting this engine family. The same engine (M274) in other models — including the C-Class (C300), E-Class, and GLC-Class from the same model years — has been recalled due to serious issues affecting engine reliability and safety. The specific issue I (and many other GLA owners) have encountered is the activation of the Check Engine Light, accompanied by diagnostic trouble code P052E71, which refers to a malfunction in the crankcase ventilation valve. This is a well-documented failure associated with the M274 engine and has been a primary reason for recalls in other Mercedes-Benz models. The malfunction leads to engine performance problems, potential stalling, increased emissions, and poses long-term mechanical risks if not promptly addressed. My Mercedes-Benz GLA, which shares the exact engine platform (M274) and falls within the same production period as the affected C-, E-, and GLC-Class models, is experiencing this identical issue. Yet, Mercedes-Benz has excluded the GLA model from the recall, despite no technical justification for this omission. This selective treatment is concerning, especially given the safety and environmental implications of the defect. By failing to include the GLA-Class in the recall, Mercedes-Benz is leaving affected owners to bear the cost of repairs for what is clearly a manufacturer defect — one they have already acknowledged in other platforms. I urge the federal safety agency to: Investigate the exclusion of GLA-Class vehicles from the M274 engine-related recall; Require Mercedes-Benz to expand the recall to include all models sharing this engine, especially those exhibiting the P052E71 crankcase ventilation valve failure; Ensure affected GLA owners receive the same safety protections and

Following regular maintenance of my 2016 GLA 250 with my mechanic for the car repeatedly stalling, the mechanic discovered there is a fuel leak causing the fuel injectors and fuel rall to not get proper fuel injection. The mechanic found a manufacturer’s recall for the make, model, and year of my car. My car’s VIN# says this particular car is not affected. However, the exact issue is presenting in my car, which can cause significant engine damage. It’s believed my car, with the same make, model& year, is indeed impacted by this issue. My VIN should be considered to be included to have this recall.
