2009 Chevrolet HHR Panel LS 4dr Wagon (2.2L 4cyl 5M)
6 months after purchasing my HHR, I found rust on the bottom, inside seam on 3 of 5 doors. 8 months later, the rust returned, worse then what it was before it was repaired, but now on all 5 doors. It was repaired again just 2 months ago and I will be watching. I have looked at two other HHR's they have rust on the doors as well.
