Dash crack far left corner on 07 Avalanche causes airbag unit to not sit properly in mounts. Area on indicated part of dash flimsy not reinforced. Damage caused by heat (speculating, ) spilt 2" from 0" in 6hrs during drive from san diego ca to las vegas nv, no prior damage or signs of stress. Due to passenger airbag not seated properly, afraid if airbag deployed may not deploy correctly. Dealer considers crack cosmetic, says airbag is independent and should not be affected which I agree but that doesn't mean it will open if it can be "jarred" from its seating in the dash if it can dislodge. And in an accident with enough force to deploy airbag it could be thrust upward from its seating and thus changing the angles of which it is intended to cover during deployment. I see a potential flaw here due to oversight in engineering and feel it needs further review. I have included a video I found on youtube that shows a dash in a 07 Tahoe (same dash as 07 Avalanche) which is cracked the same way, it clearly shows how due to this crack the airbag unit is not secure in its seating and could potentially "jump out" as well the flimsiness in the dash area I am speculating towards lack of reinforcement. www.youtube.com/watch?V=_drp8slwvgo&feature=related *please note that no crack or indication of stress was visible 2 days prior, dealer considers crack to be strictly cosmetic and not covered under warranty. I agree the crack in nature is cosmetic however being that it can disrupt a crucial life-saving component the manufacture should be required to repair so that all possible effected systems function correctly as required.

I had been noticing that there was a slight noise on the right front end of my 2007 Avalanche. I checked the undercarriage and didn't notice anything wrong. I had an oil change done and it came w/ a free tire rotation. The sound seemed to be gone after that, I can't be sure. The truck had approx. 12,000 miles on it. I was going to drop off some papers with a customer on Oct. 6th when I heard the noise again. I was looking for the customer's tractor that we were repairing in the field and was slightly bothered by the sun so I put one of my hands up to block the sun. When I looked back at the road, I was in the wrong lane. I tried to correct and the vehicle accelerated on it's own! I applied the brakes but didn"T get the same response as before. I ended up in a concrete ditch. By the way, the airbag didn't deploy and the onstar didn't get help there either. I talked to GM and they kind of just brushed it off. I still have physical and emotional issues because of it.
