Shifting assy

[stoney]

I have a 2005 SUT and have had it back to the dealer SEVEN times for various problems, The most serious being the shifter assy. Once it locked in the parked position and had to flat bed it to the Dealer. Two times tha the handle became loose. I called GM consumer and am not satisfied.I have to bring it back to the dealer(I am bringing it to a new dealer) again they just changed the whole shifting assy and in three days it became loose AGAIN. The other problems I have had are the side view mirrors not working properly (twice) feedback from my radio system) and other minor things. In spite of it all I still love my Hummer. I want to know if anytone else has these problems. I would appreciate any comments on this situation.
Thanks
