2005 Malibu Alignment

I have a 05 Malibu and the rear end of the vehicle went out of line. Well this was at least what I was told by a tire shop and alignment center. I know something was wrong because it did wear out the rear tires very uneven and they eventually had to be replaced.

So the tire and alignment center said it needed shims to align it back up properly to solve the issue of rear tires wearing out prematurely. So I approved the necessary repairs and had it fixed as recommended and the tires replaced. A few thousand miles later it did it again well was still wearing uneven and on the road to wearing out the edges first.

I took it back to the same place that said it was fixed for another inspection. The rear end alignment was out again. They did not know why so they tighten things up rotated the tires side to side (Cris-cross) and front to back and said to drive it. I never heard of a rear-end going out of alignment but this thing did. Now I need to replaced two more tires sooner then expected. Have you heard of this issue before. Is it a Chevy Malibu common Problem? Do you think I should call Chevrolet customer service for assistance?
