“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!!”
NHTSA complaint #10490928, filed 2013-01, 78,000 miles“Gmc has the door handles made in mexico out of plastic. When you go to open the door the handle breaks off in your hand. Gmc knows this a major design flaw but refuses to stand behind the problem. Just google GM door handles break and hundreds of postings come up! My child went to get into the truck the other day and the handle broke off in his hand causing him to fall backwards.”
NHTSA complaint #10605883, filed 2014-06, 8,822 miles“Dash cracked top left corner passenger side air bag. This is a very common problem simply google Gmc cracked dash and you shall see. If the air bag deploys plastic shrapnel would be sent all over the cabin. Very dangerous problem that GM is ignoring a recall should be issued.”
NHTSA complaint #10559297, filed 2014-01, 58,000 miles“External left rear door handle pulled off when simply opening the door 11/15/2010. External left front door handle pulled off when simply opening the door 12/15/2012. Two door handles pop off on a new vehicle not a defect? Same flimsy plastic fastener attachment broken in both cases. Google search indicates this is a common defect experienced by numerous owners that Gmc and chevrolet will not admit to. The Gmc dealer even acknowledged it's a defect! Repair cost - $300/handle!”
NHTSA complaint #10489378, filed 2012-12, 18,000 miles“Major issue involving cracking of dash around passenger airbag opening and instrument cluster area. I have noticed several vehicles covering all years and usage with similar cracks some major. Concerned that if an accident with front air bag deployment injury could occur due to fractured plastic.”
