I have the 2013 Ats 2. 0 turbo and I had a few issues with it. The first is steering,sometimes feels like power failure, its the only new car I owned when the car is off the wheel turns completely. Also pulls to right. Other issue I get banging noise when put in reverse,and a few times sounded like trans making race noise. The cue system is a joke,when my trial for xm ran out I tried to listen to fm rdi and that's a joke,I cant listen to one song,there's static eighty percent of times. Other issues ride is horrible rides like a trans am and shakes when hit bumps. After coming out of a Acura and Honda I now know why I stayed away from gm. Oh forgot the engine shakes at idle feels like stall,then revs up. All the dealer does is says meets designed function. I ask myself a car this expensive is it supposed to be crap.
