I had a similar run (although mine did not result in an altercation

) in with a Pontiac svc dept on my firebird re: warranty work and mods to the car...the svc manager threatened to void my warranty on their dealer network database so I could not get future warranty service anywhere. I had to get the GM district mgr to intervene and authorize the TSB work.
I wonder if this dealer could do the same on OASIS?
