The contact owns a 2017 Mercedes-Benz GLA250. The contact stated that the warning light that the driver’s side air bag required service was illuminated. The contact stated that the warning light was constantly illuminated. The vehicle was taken to two independent mechanics, and the contact was informed that there might be a recall associated with the VIN. The contact stated that one of the independent mechanics retrieved a DTC that the "Squib to the Driver's Side Air Bag had an Open Circuit" and needed to be replaced. The vehicle was not repaired. The contact called a local dealer and was advised that there was a recall for the year, make, and model vehicle; however, the VIN was not included in the recall. The vehicle was not repaired.

To Whom It May Concern at the National Highway Traffic Safety Administration (NHTSA), 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 NHTSA 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

Stearing wheel began to make a clicking sound and would hardly turn. The Front Left Malfunction Service required light came on and when I took it to the dealership they informed me that the clock spring and airbag are broken and need to be replaced. He stated the vehicale is drivable but the airbag does not work. In 2017/2018 there was a recall for this exact issue and it shows my car was impacted and the recall repair was completed but that was prior to me purchasing the vehicle. Because the recall has been closed they will not honor repairing it and the vehicle now does not have a airbag that works properly.

Check engine light received a diagnosis from Mercedes dealership that the crankcase ventilator line is malfunctioning and it’s a very common issue with this model. The transmission stalls during driving, the gears do not jump properly and the car cannot reverse, extremely dangerous at intersections and on the highway. Car needs to be turned off, cooled and restarted. This issue first appeared within a month of owning the vehicle from a certified Mercedes dealership. Refused to help during COVID, and by the time they were taking appointments again (two to three months after warranty expiration), warranty expired, would not honor and refusing to offer any help currently, expensive repair.

A few times a week I will go to start my car and the smell of gas is too much to bear inside the vehicle! You can smell it for hours and is hard to drive with the windows up!

Took vehicle in and was charged $1500 no smell for about a week then called to let them know issue is still there took car back and was told the couldn’t smell anything. Started February 2023 as of today one year later still have the gas smell in vehicle repair shop is just taking my money and want me to keep bring in vehicle but issues still exist.

I have a 2017 GLA-250 with 90k miles and check engine light is on. My mechanic told me it was engine code P052E-71 crankcase ventilation valve and was a very known problem with 4 cylinder turbo engine and mercedes benz has extended emissions warranty for this issue. Called Mercedes dealership and they told me my model was NOT covered. Only models 2015-2020 C/E/CLC/SLC/SLK. What a bunch of crap! All these models have the same engine. Cost of repair $2,300. I will never buy another Mercedes again. Company doesn't stand by their product when they know they have a known problem. My model should be covered. This is an emissions problem that they should recall for all models with 4 cylinder turbo engine

car engine turned off by itself in the traffic. It has happened a few times when I was waiting at the traffic light or waiting in lane to make turn. The engine suddenly turned off completely and I was caught in the traffic.
