What owners are reporting 1 most recent
Engine light comes on after long drives and hot weather. After several inspections by my mechanic, I was told I needed a new turbo. I have 147,000 miles on the car. He told me my car would just stop at some point. Is this really the problem? The engine light is scary. It happens while driving on the freeway.
