2017 Mercedes-Benz GLA-Class

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. The contact researched online related to the failure of NHTSA Campaign Number: 17V627000 (Air Bags). The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 60,000.

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.

LIGHTS ALL CAME ON AND SAID YOUR CAR WILL NOT GO INTO REVERSE

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

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!

1. *Component Failure*: The sunroof/moonroof has stopped functioning correctly due to broken plastic rail guides/sliders, causing issues with opening and closing. Additionally, there's a potential risk of the sunroof detaching from the vehicle due to faulty bonding between the sunroof glass panel and the sliding roof frame. 2. *Safety Risk*: The safety risk is significant, as a detached sunroof can pose a hazard to other road users if it separates from the vehicle while driving at high speeds.

On a few occasions, the car shifted into neutral on its own after being in the drive gear. This is quite dangerous and unsafe. There are no warning lights or indications. I noticed this problem a few months ago and it has happened a handful of times. I have don’t extensive research on similar problems and have only found forums with other gla drivers experiencing the same problems. There is no recall that I can find regarding this issue. The dealer is also unaware of this issue.

The command screen has completely went out, similar to the same active recall on newer models.

The sunroof doesn't close. Wind and rain is getting into the car. I took the car to the dealer this morning. Problem was verified. There were no warning lamps or messages. I understand there are numerous problems with this sunroof.

When turning, I hear a thumping, grinding or chatter noise from the rear differential and the car slows. Mechanic changed the differential oil and found metal shavings/particals. Noise was not there for about 80 miles but has returned. I have to get a new right differential. I checked on the forums and this seems to be a common problem, one owner has had to replace his differential 4 times.

Car was driving two separate times and it turned on an auto magic braking system Or engine stopped on freeway
