Check engine light on my 2015 MB GLA250 4matic came on and the error is "P052E PCV Regulator Valve Performance". There is a recall for other MB vehicle with the same engine. I believe the 2015 Mercedes-Benz GLA250 and other models with the same engine should be included in the recall.

Today a Check Engine Light turned on my vehicle. I pulled the code via the OBD2 port and looked it up online. It turns out that this issue, code P052E, a defective Crankcase Ventilation Regulator Valve, is a well known problem on in-period MB cars and the manufacturer has issued an extended warranty to other models in their range, but excluded the GLA250, which uses the same parts as several other covered models including the GLC300, a vehicle covered by said extended warranty. If left untreated oil can travel up the electronic lines, ultimately fouling the ECU leading to an extreme hazard. This fault is also extremely expensive to fix, about $2000, as the faulty part (alone about $70) is sold only as a component of a larger kit (about $700), and installing the kit requires removing motor mounts and hoisting the engine. Mercedes should either widen the Extended Warranty to cover all of it's vehicles built with the defective part or issue a recall.

Good Afternoon, the status of my vehicle is simply UNKNOWN. I purchased my vehicle on the 26th last year of January. That same day I drove it back home my car was jerking. So I went back the following day to see if I could get into another vehicle because this one was malfunctioning they didn’t want to do anything for me. I tried so many different options to get out of this car I had a few scares driving this car the week of ownership. About sis times my car cut off completely during traffic and I have some recorded videos. Theirs a leakage somewhere I can fill up my gas tank to full and drive maybe two blocks away from my house and the gas meter is say that I have half a tank. Now my car is overheating, it’s not cranking it just tells me on the dashboard that 4MATIC is unavailable.

My 2015 Mercedes Benz GLA check engine light came on for error P052E Positive Crankcase ventilation assembly. This is a $2,000 dollar repair because you need to buy the whole assembly and you can’t just buy the valve like other cars. This part has a recall on other models but not the GLA. For example the metrics uses the same part and is covered by a recall but not the GLA. We need to included in this recall. This design flaw renders my 2015 useless and virtually has no value. Please compel Mercedes to recall this defective part and design flaw that requires 6-8 hours of labor for a simple part that is easily accessible on all other cars.

The engine light is one and the related code for the engine light is P052E-71. The valve for Crankcase ventilation has a malfunction. There is recall for the code for other Mercedes Benz car model varies from 2015 to 2019. I believe this code on for GLA 250 is the same manufacture malfunction parts and should be recalled for free replacement for safety reason.

When it first started to malfunction, my car would suddenly loose power out of nowhere and pretty much stop wherever. It's done it when I was crossing a busy intersection and it stalled right in the middle of the road causing other cars to have to stop or go around me. It has also stopped while I was driving on the freeway. I didn't even have enough power or momentum to pull off to a safe lane and almost caused an accident and several times while I was driving up a narrow two way road in the mountains. Later down the road my check engine light came on and I got the code p205e, Crankshaft ventilation breather hose is clogged, then my car lost power for good. It has been parked for almost a year now because I can't afford the repair and I am still paying car payments and insurance on it

We own a 2015 Mercedes GLA. There has been a voluntary extended warranty due to a known issue on their end for years with this very expensive fix on low mileage cars. The voluntary extended warranty for this issue is not including the GLA class, when Mercedes has known this is a known issue and defect with their vehicles at the detriment and safety of the owners who unknowingly have to deal with this. I am writing to encourage the NHSTA to have Mercedes be accountable for this issue outside of the complaints related to the C class.

The car had only 71,000 miles on it when it it had a crank no start situation that immobilized it and had to be towed. After diagnostics at two repair shops, it was determined that the exhaust camshaft was the cause. This model year car has a recall (Mercedes campaign 2015100009 and NHTSA campaign 15V662000) for the camshaft but not for the car's VIN. This failure should not occur in a car with this mileage. Had it suddenly stalled while driving, it could have resulted in a potential accident.

IT APPEARS THAT WHEN THE TURBOCHARGER IS ENGAGED, COOLANT LEAVING THE TURBOCHARGER IS SPRAYING FROM WHERE A PRESUMABLY NOW MISSING CLAMP WOULD OTHERWISE FORM A TIGHT FIT AROUND THE TUBING, WHICH IS NORMALLY HOUSED BENEATH HEAT SHIELDING. THE HEAT SHIELDING HAS BEEN DISPLACED BY THE HIGH PRESSURE PRODUCED BY THE HOT LIQUID. THE LIQUID IS SO HOT LEAVING THE TURBOCHARGER THAT AS IT SPRAYS OUT ONTO THE SURROUNDING AREAS IT HAS MELTED THE AIR INTAKE SYSTEM.
