I'm not a mechanic but I do have a 2017 LT with 21K miles (bought used at 17K). Haven't noticed any oil leaks or consumption - no engine problems.Looking to buy either a 2017 Chevrolet Trax for my wife. I've heard earlier models are known for leaking oil and breaking pistons. Has this issue been fixed for the 2017 edition? Looking for advice. Any mechanics out there that can weigh in?
