After almost 5 five months from the time a purchased my new 2013 lancer mx, I notices a bit of uneven height on the back part of my car. The left side seems to be lower than the right side. I measured it from the center of my wheel up to my fender. There is a difference of about half of an inch. I already went to the Mitsubishi shop but what they only did was interchanged the shocks of the left to the right. And I was told that it's already even. But when I checked it the next day, the problem still there. So I brought it back again to Mitsubishi, but then they told me its within the allowed difference. Im not sure if there's really a problem on my car or not. Help would be very much appreciated.
