“Gmc dash recall my 2008 Gmc sierra dash is cracking and I looked up the problem on google and it looks like thousands of others have the same problem as me. The dash is cracked in such a way that at a certain angle I can see wires exposed from the airbag cover. I would like to see a recall to fix the cracked dash.”
NHTSA complaint #10958891, filed 2017-03, 116,000 miles“I have a 2008 Gmc SIERRA 1500 I bought brand new and my dash is cracking severely in two different places! One is right behind the passenger side airbag and is about 1 1/4 inches and the other is on the driver side above the guage cluster and is about 6 inches or more!”
NHTSA complaint #10923888, filed 2016-11, 46,000 miles“2008 Gmc sierra denali has 2 cracks on the dashboard, one by the airbag and the second over the drivers side dashboard. This is definitely a manufactures defect that Gmc is totally ignoring. Does someone have to be maimed or killed before they take reasonable accountability instead of just denying everyone until we go away? We need government intervention to hold them accountable. The dash board rattles and shakes over every little bump!”
NHTSA complaint #10874141, filed 2016-06, 36,000 miles“Here are huge cracks on my dash!! I'm afraid if the air bag comes out it will bust the dash in pieces and there's no telling where it may hit! This is a huge problem in these vehicles and it's insane that y'all not GM will address the issue”
NHTSA complaint #10979099, filed 2017-04, 89,000 miles“The upper dash panel cracked after being parked outside. I thought someone broke in and hit it with something, it is cracked down center of instrument panel toward windshield then across to air bag compartment. My fear is that if the air bag that is pending recall information passenger air bag deploys and passengers could be hit by plastic shrapnel. Another concern is a child gets hand or arm injured by simply pressing too hard on flimsy dashboard. I am a 100% service connected combat veteran and need to sell truck to purchase a van for transportation. …”
