I have this 2015 GLA 250 56,000 mileage had a check engine issue and brought to stealership and it is my auxiliary electrical pump oil that needs to be replaced and would cost me $2185. Does anyone had the same issue as mine. I am off warranty and now I am starting to find more issues every time I go to the dealership. Last April also I had issue with my Engine control module for crank case ventilation valve that cost me $1500. This is really ridiculous that for this half of this year I am already spending $5,000 including the maintenance cost. And also I smell gas inside the cabin when I turned my car on and it happened last time when heater was on. I will take any advices or reactions.
