you can file a suit against them ,winning it is another story ,but i think in your case you would have a good chance of winning this one,you,ll have to get a statement from a mechanic finding the exact fault as to why they didn't deploy,and go from there with it,you cold win this one with a real good lawyer though,but remember who your up against,gm,they have many good lawyers for this kind of matter,good luck on it.
