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.

All MB GLA and CLA 2015 cars have a common issue "CRANKCASE VENTILATION VALVE" which should be replaced a few times for the cars. Each service will cost at least $2000.00. Please ask MB to recall their cars and fix this issue.

STRUCTURE:BODY, UNKNOWN OR OTHER
The panoramic sunroof will not open on one side rendering the sunroof unusable. this problem is happening often on this Mercedes model. Looks like Mercedes used plastic guide to move the sunroof back and forward and if you take a bump while driving with the sunroof on the tilted position it will break the plastic tracks rendering the sunroof unusable. this is a time-consuming fix because the interior of the car needs to come out to completely remove the sunroof and replace the damage part with the same original part that will break again under the same circumstances.

ENGINE, FUEL/PROPULSION SYSTEM
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

Panoramic Roof exploded without any outside influences causing this...many on your radar...dangerous...not sure why the NHTSA has not ordered a recall...there have been thousands of these same issues across many manufacturers. Almost caused a crash due to the startle effect of the explosion. MBZ does not make a replacement part for this. Why is that? There's a reason behind this. It's the gov'ts responsibility to keep us safe...Insurance paid for the replacement...MBZ does not make it...there are no aftermarket replacements for this. Dealership has had the car on it's lot for 5 weeks...it's been out of order for 8 weeks.

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.

FUEL/PROPULSION SYSTEM
On September 7th, 2023 while I was on the fastest lane driving to work in the morning on I 10 fwy, the car shut down without any prior warning. Couldn't even put it in neutral. Called 911 and a cop called the towing service to take the car out of the fwy. Mercedes Benz Ontario dealer diagnostics says it's due to a fuel pump failure. I see a same issue recall, but not for my model. Mercedes should check if my model sold also has a similar fuel pump failure issue. It's very dangerous to stop without any warning.
