This has happened before, but sounds to me as though the problem was different. There is some type of clip near the column/dash that can either break off or come loose and become wedged somehow, thus preventing you from shifting out of [P] There is a thread on here somewhere about it, try searching maybe.
I think that if that^^ was the problem, the dealer would have easily reconciled the problem by now. Sounds to me like larger issues. If indeed they do need to replace the entire column, feel fortunate you're covered under warranty. Just so you know, this isn't a common problem at all, so I wouldn't worry about it happening again after this fix.
