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.

On April 2 2015 I experienced "reduced engine power" while taking my daughter to urgent care. The vehicle has had over $2000 work with many different repairmen involved. Gm advised they were sorry but no recalls - nothing they would do to help. Numerous times, we have come close to being involved in an accident when it occurs. We will be driving at normal highway speed, hear a bing and see reduced engine power flash on display. Vehicle will immediately go from original speed to no more than 30-40 mph - no warning. It is unsafe to be on a busy road as anyone could rear end us, killing my family.

The contact owns a 2006 GMC Yukon xl. The contact stated while driving approximately 40 mph, there was a complete loss in the engine power for a brief moment. The vehicle then resumed normally. The failure recurred two times. The vehicle had not been diagnosed or repaired. The manufacturer was not notified of the problem. The failure mileage was unavailable.

Reduced engine power forced the vehicle to remain under 25 mph on a busy road where I was unable to pull off due to lack of shoulder. Restart of the vehicle after I came to a place I could stop, yielded the same error and lack of power.

Going approximately 5-10 mph on a side street the engine surged when brakes were applied and the brakes did not work. Had to put the truck in park to stop. SUV was immediately towed to dealership. Dealership reports no computer record of incident nor problem with the engine or brakes over a period of a week of testing. ## VIN passed ## GMC, Yukon denali, 2006 ##.
