general problems of the 2006 GMC Yukon

My vehicle was in motion driving on the freeway at 70 mph when all of the sudden my car lost power to 30 mph all the way down to 5 mph. I pressed on the accelerator trying to gain speed without success the car did not accelerate more than 30 mph, no matter how much I pressed on the accelerator. When I looked down at the dashboard I saw two warning lights go off "stability sys disabled" followed by "reduced engine power" luckily I was able to move to safety. The road was dry and no bumps to disable stability. The traction control in this vehicle is located far from my steering wheel so I know I did not accidently hit the traction control by accident. After I was able to pull over I was advised to hit the traction control button to see if that would fix the error in the dash. That did not work. I immediately took it to the dealer concern for my safety and that of my family. The dealer has had my for several days returned my car back once stating that it was due to master air flow sensor along with the air filter once those parts were replaced I picked up my car as soon as I picked up the car and drove it around the corner I experienced the same issue. I drove it back to the dealer at 5 mph as I was not able to go any faster no mater how much I pressed on the accelerator. 2nd time the car was returned to me I was told it was just the butterfly in the throttle body and that it was replaced for a new one. I was driving away and got just a little farther than the first time when I got the same error message again I drove it back to the dealer and they told me it was a faulty throttle body they replaced that but its still having issues. I believe this to be a safety hazard while driving I want this noted in case there is a major accident with fatalities.

While accelerating from a complete stop the the vehicle goes into traction control for no reason stalling in the middle of the intersection. The display flashes traction active even though the pavement is dry and free of loose debris. You have to let the accelerator go and re-accelerate to deactivate the traction control, leaving you stalled in the middle of the intersection. Gm had a recall for large suvs and pick-ups with a very similar problem, the only differance was the display flashed an abs fault but the repair for that recall was exactly the same as for the traction active fault. Abs is part of the traction control system, so just because gm found a way to throw a different code for the exact same problem they're not obligated to take care of this potentially very dangerous problem that leaves you in no control of your vehicle in the middle of an intersection while moving from a stop light or stop sign. Please look into this before somebody gets hurt or dead from getting t-boned because they can't get out the way.
