My 2016 Mercedes-Benz CLA 250 (VIN: [XXX]) has a check engine light for code P052E, which points to a broken crankcase ventilation valve. My car has only 59,000 miles on it, but this same exact part already broke once before and was replaced under the original warranty. Now, the replacement part has failed too. This proves the part is defective and keeps breaking. Mercedes-Benz already knows this part is defective. They gave a free 15-year or 150,000-mile extended warranty to fix this exact issue for free on the C-Class and other longitudinal M274 engine platforms. However, they are actively denying coverage for my CLA 250's M270 engine variant, despite the two vehicles sharing nearly identical engine blocks, matching subcomponents, and the exact same broken part. Because of this unfair engine code technicality, Mercedes-Benz is forcing CLA owners to pay thousands of dollars out of pocket for a recurring problem they fix for free on a C-Class. I urge the NHTSA to look into this engine loophole and force Mercedes-Benz to include the M270 engine variants under the 15-year/150,000-mile free repair program.

ENGINE
I am reporting a P052E fault code related to the crankcase ventilation system on my Mercedes-Benz GLA. This is a known and widespread defect on multiple Mercedes-Benz models and is commonly covered under service bulletins and extended warranties up to 150,000 miles. My vehicle has 92,000 miles. However, Mercedes-Benz has refused coverage, stating that the GLA model is not included, despite extensive evidence that this same defect affects GLA vehicles. Numerous documented owner reports and forum discussions confirm identical failures on GLA models. This appears to be a systemic defect rather than normal wear. I am requesting that NHTSA investigate this issue and require Mercedes-Benz to extend coverage and assume responsibility for repairs on affected GLA vehicles.

AIR BAGS, STEERING
My airbag malfunction light appeared on the dashboard. Once the light appeared, the HORN STOPPED WORKING, a safety hazard that caused me not to be able to drive my vehicle for over a year due to the risk! I took the vehicle to the Mercedes-Benz dealership, 200 S Pickett St, Alexandria, VA 22304, and was told that the recall was closed and that they could not assist me. I was advised to contact NHTSA. PLEASE HELP AS I WOULD LIKE TO DRIVE MY VEHICLE & BE SAFE ON THE ROAD! This is a huge safety hazard!!

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
My GLA250 Instrument Cluster had been glitching out. The turn signals indicators would go off when the turn signal lights are initiated. The Check engine light, high beam light, and other warning lights come on for no reason, or dim or no backlight, inaccurate gauge readings, erratic gauge needle movement, and even a completely dead cluster. I took the car to the dealership and they said the instrument cluster was faulty and needed to be replace. The car is still at the dealership because they haven't figured out how to program it right. Since the instrument cluster is a vital component of the vehicles safety feature, this should be a recall. I have spent $3500.00 to fix an issue that should not have occurred since the car is only 6 years old. There are several online forums that discuss this very same issue that Mercedes is having with their instrument clusters.

SERVICE BRAKES, POWER TRAIN
Transmission from drive well sometimes shift to neutral while it is at a stand still usually waiting for a light to turn green, after which it takes its time to shift back into drive. While this happened a warning light appeared malfunction take straight to dealer. Yesterday seems as if ABS kicked in while driving, threw me into the steering wheel than stopped shaking within 1-2 sec, and let me accelerate off. Was passing in an individual at the time. Don’t know what to make of it.

Engine runs fine while driving and then cuts off while coming to a stop. This happened three (3) times last week since 7/23/24. Each time it happened I was stopping at a traffic light! After the failure a warning lamp flashed something about, Do Not Change Gears. Will make appointment to have it checked out as soon as possible.

FUEL/PROPULSION SYSTEM, ENGINE
The contact owns a 2016 Mercedes Benz GLA. The contact stated that the check engine light had appeared on the instrument panel. The vehicle was taken to a dealer where a diagnostic was performed. The dealer determined that the crankcase ventilation valve had malfunctioned which blocked the actuator. As a result, both the fuel and the oil had started to mix inside the engine which caused the ventilation valve to not close as intended. The contact was given an estimate for repair. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 63,000.

ENGINE, FUEL/PROPULSION SYSTEM
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.

While driving the vehicle a message is constantly required to acknowledge an SOS inoperable system which can be dangerous while driving. Mercedes ME Brace no longer supports the system due to being an obsolete system 3g network. The dealership requires the system to be disabled by deleting the software or removing the component to fix the issue of SOS being inoperable at a cost to the customer.

While driving the vehicle the system shows SOS as inoperable and requires constant acknowledgment by the driver while the car is in motion. This is a safety issue especially when driving and the driver loses focus on the road, it removes the digital speedometer and has to acknowledge the system error and potentially can be in an accident when not focusing on the road. Mercedes mbrace no longer supports the system due to an obsolete 3g system that is utilized causing the system to show an error as SOS inoperable. There is no software service patch to fix the issue of lost connectivity that is no longer supported by Mercedes. The dealer ship recommendation is to troubleshoot and repair that cost the customer to pay out of pocket even though this is not supported and no longer can be used as a system. Or to completely rip out the system

ENGINE, BACK OVER PREVENTION: WARNINGS
I was driving on the highway and when I stopped because there was traffic my car completely cut off. Screen and display went back and then it came back on and went into neutral and when I went to shift gears and try to change into drive it would not allow me to change gears. I had to turn the car off and turn it back on. THIS WAS ON THE HIGHWAY!!! This happened 2 times on my way home. I have a 2016 Mercedes my coworker has the same vehicle but the 2015 model. She has the SAME ISSUE. Her car is in the shop now and the mechanics are trying to see what the issue may be and I have an appointment at the end of the week. I have looked this issue up and there are TONS of people reporting this issue and I cant believe there is no recall! This is beyond dangerous and someone could die because of this. My coworker brought it to my attention and if we didn't drive the same vehicle I wouldn't have looked into this. However its NOT a coincidence that we both have Mercedes same make and model that cuts off and goes into neutral when driving.
