if they are replacing the airbag over the glove box they do sort of have to touch the dash otherwise it will just break more, mine has a fine crack right where the airbag is, I have had it out it has clips that go into the dash although it is bolted in from below
they really have not issued it all out yet the decision was just made about a week ago, I don't think GM has filed the public report yet. they have 60 days to notify everyone affected What if my car isn't recalled now? Could it be recalled later? Yes. Whether a manufacturer independently conducts a safety recall or NHTSA orders one, the manufacturer must file a public report describing the safety-related defect or noncompliance. Manufacturers are also required to notify owners by mail within 60 days of notifying NHTSA of a recall decision.
That's good to know. But with the # of vehicles affected, I have no doubt it will take a while to get replaced. I've heard of people with Toyotas waiting years for a recall.
The most likely cause of the airbag light in these trucks is front crash sensor corrosion. I just replaced both in my 09 Denali. I probably have some time before the ones in the Suburban crap the bed because it's garaged and not a DD.
