Open the full vehicle complaint log (all categories)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.
