apr. 2012 2yrs. after purchase front 2 inside door bottoms the paint started to bubble. Took vehicle in to dealer where I bought it, they took pictures and sent them to GM which in turn okayed them to sandblast and repaint door bottoms. 2yrs. 4 mos later the back 2 doors have done the same thing plus the drivers front door has started to bubble again. I took vehicle in for maintenance and brought this to there attn. They took pictures again and sent them to GM once again. That was a week ago , still waiting for result.They told me at the dealer that paintwork is only covered by GM for 3yrs. They told me that GM would asses it but I still might have to pay to have it fixed. This does not hold well with me as I purchased the extended warranty to 5yrs. What kind of shape will these doors be in 2yrs. from now? I have seen doors on vehicles over 14 or 15 yrs. old in the junkyard that have no sign of rust on the bottoms. You would think they would have a remedy for this. I'm definitely not a happy camper. My next vehicle purchase will depend on what the outcome of this will be.
