Just bought 2014 Chevy Cruze 1lt 1.4L. Had about three weeks. When get on highway driving 65 mph. Its hard keep car between lines cause of jerking side to side and notice tonight it was wobbling back and fourth at that speed. Car only has 18k miles on it. Any clue what going on? or this normal for this car. I got off highway cause of it. Keeping thinking hit another car or something else.
