Here is an article from The Hill that gives more information on how existing products liability claims against GM and Chrysler will be handled. Bottom line: claimants will be unsecured creditors, and will be thrown into the pot with all of the other unsecured creditors.
Of course, to the extent that the claims are covered by insurance, and the insurance company is still viable, the money should be paid. The problem, of course, is that the self-insured retention for these companies is quite high (I don’t know how much) and thus those able to prove their claims will be in the unsecured creditor pool for the retention amount and can only look to the insurance company for excess amounts.
For my other posts on this subject look here, here, and here.
