One problem related to paint has been reported for the 2006 Chevrolet Trailblazer. The most recently reported issues are listed below.
Door paint start ti bubble this fist was notice after I hit the 1,000 mile marker. The paint was repaired by the dealer. Then 3 years later the paint bubble again on all my doors and the back hatch and front hood. It was then repaired by the dealer. 3 years went by and the issue is back the dealer states they do not know why it keep doing that and is unable to fix it again. I feel this is a paint issue with gm. My 2005 Trailblazer was having the same problem with the paint around the doors. I am now stuck with a large cost to get this repaired again due to an issue with the paint that I been dealing with since I first bought the truck.
