How many miles are on the car? I can't speak for your dealer, but my suggestion is to ask the dealer for the number for GM customer assistance. Call them and plead your case. I have seen many cases where a claim was not covered, then after the customer called the assistance number, the repairs were warrantied or split with the customer (GM bought parts and customer paid labor). Worth a shot at least.

FYI, it's not the dealers descision on weather or not to cover it. If the dealer decides to do the repairs and then GM kicks it back, the dealer in on the hook for the repairs.
