He clearly doesn't need you to chime in because to the best of my knowledge you have never added anything on a thread other than noise. The OP came asking for what his options are. You have given no options. So once again you have been useless.
There is no obvious malfunction that wasn't caused by what he hit. For all we know he drove for miles without noticing a warning light. That happens all the time.
His issue needs to be taken up with his insurance company, not the maker or the dealer.
