Bought mine in late June and for a brief second I thought I should wait and see if there are any problems, but the looks of this truck won me over.. I'm kicking myself now . Its had the tires road force balanced and no they are replacing the tires. I bought a new truck expecting it to have less problems than the 8yr old 140xxx mile truck I had. This is my second GMC truck and my first brand new one . I'm very disappointed. 2014 GMC Sierra Crew Z71 4x4
