I really have to ask why are you wasting your time with us then if you know what to do and we have no clue?
All you are doing is repeating yourself over and over. If this is the tactic used at the dealer , no wonder no one is taking you or your issues seriously.
Fix the car , sell the car or throw rocks at it but spinning your wheels here is not helping you fix it.
Good luck and i hope you get it fixed.
