GMC DOOR LATCH User Comment / Complaint

On 12/21/04 i brought my 1997 corvette to the dealership to get serviced for the "#4006 electronic column lock system" recall. last thursday (8/11/05) my vehicle's steering lockup up while moving out of my parking spot. it was towed in to byers dublin chevrolet dealership (614-793-4800) the next day. i was told that this was not covered by this recall and that i needed to purchase another steering lock actuator for $475. i have read on various newsgroups that this type of lockup can happen over and over again if the lock plate is still in place. i have requested to the dealership to just remove this lock pin and i would be happy to pay for their labor to do so, but they refuse to do it. i've talked to chevrolet corporate (ticket # 1-355691956) and they still refuse to put in a bypass or to remove this lock altogether. can you give me some advise on how to resolve this so that i am not driving around in a car that could have the steering column lock up at any given time? it is a hazard for me and a liability to chevrolet. thanks, -kevin.
