Driver's seat moves left and right when turning. Took it to the stealership and they put some "shims"in the track or somewhere to stop the problem.. It worked for a few hundred miles, but is doing it again. I'm not sure what was wrong with the seat track system they used in the older models. It worked fine for 475,000 miles in my 2002. When I took it to Chevrolet, they said they have had a lot of customers with the same problem. Why hasn't Chevrolet had a recall? This $60,000 vehicle isn't worth it!
