NHTSA Complaint #11585554 — 2018 MERCEDES-BENZ GLA 250

My Car's warranty expired in Dec 2022 and a few months later the engine light came on. It stayed on for a few weeks than was turned off by itself. In Dec 2023, the engine light came back on again. I also noted jerks when driving slow (10 miles/h). Upon checking with Mercedes Benz of Tri Cities-Richland, WA, spending $400 on diagnostics, the staff quoted me $3500 for Crank Case Ventilation replacement. This is a really expensive part/labor and it is ridiculous that Mercedes does a poor job! A quick online search proved that this issue is pretty common in MBenz models, there should definitely be a recall. This is inconvenient and appropriate actions should be undertaken against this.
