Two problems related to door have been reported for the 2008 GMC Sierra. The most recently reported issues are listed below.
I just read the safety notice for GMC 2007 yukon interior door handles delaminating and creating sharp cutting edges (ea 10004). The exact same thing has happened on my 2008 GMC denali Sierra (driver side) - I've sliced my finger a 3rd time and am now having the handle replaced at a cost of $240. When I called GMC customer complaint line they offered no help just excuses. . . Poor customer service. . . Wow, no wonder gm went bankrupt!!.
As I reacherd to open the passenger door I sliced my finger index finger and got quite a bad splinter in my. Middle finger.
