Power Steering Fluid problems of the 2003 Chevrolet Tahoe

My 2003 Tahoe z71 has always made popping noises when turning and you are able to feel it in the steering wheel also. I have researched online and it is very apparent that this is experienced by almost everyone. Today I was backing into the driveway with a trailer of mulch attached and when I cut the wheel, the steering was lost. There is fluid in the power steering reservoir and there was no leaks or fluid anywhere. I looked underneath the Tahoe and there does not appear to be any broken sway-bars or steering shaft. I am not sure if it is the pump which would be strange in the manner that it gave out but reading all of the issues others have had, I can't believe that gm is not fixing the situation. Someone is going to cause a serious accident trying to turn and it is going to give out like mine (& everyone elses) did and cause a head on collision. I called gm & although there are 9 TSB #'s associated with this issue, there is still no recall or help on the resolution of the problem. I think it is time to sell the Tahoe that I bought brand new btw and move on to a new Ford truck as they seem to have really good trucks now. It is sad because I have loved my Tahoe z71 and never thought I would get rid of it. The steering has never been right on this Tahoe since day 1 and gm knows it but buries their head in the sand about it rather than do the right thing and fix the issue. Mine still looks brand new but the popping noises when turning has always irritated me & now that it gave out, I am done with it. I am thankful that mine occurred when it did and not when I was traveling down the road with 6 yards of mulch in a dump trailer and making a turn that could have killed me and someone else coming the other way. Fix your known issue gm, before someone innocent dies because of your negligence!!!.
