Two problems related to tailgate have been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
High mount rear stop tail lamp assembly is loose. Opened the tailgate on 5/11/09 heard metal crunching. Ever since my back glass vibrates violently when going down the highway, increasing the possibility of it blowing out. On 5/17/09 after further investigation noticed that the top assembly has broken away from the truck on both sides (still being held on by the center) should this come off it puts me and drivers behind me at risk of an accident. This problem puts my children at risk of glass shattering on them or being involved in an accident. This is my only vehicle and I have no choice but to drive it until it goes to the shop this week. I have read several complaints about this online.
Eliectrical failures. Rear passenger window would not go up, replacement of right rear taillight and fuse twice in three months and left taillight and fuse during that time. Front bumper facing comes unglued,I understand it is velcroed on.
