Hi , new here, with a question. I am looking at getting a 2012 Equinox. I was leaning to the 4 cyl, due to the better mileage, but have seen the problematic history. Do we believe that problem on the 4 cyl is solved for the 2012's (since apparently there is a known fix) or would I be safer/better off with the 6 cyl. Are people having engine problems with the 6? Thank you for any thoughts and advice.
