Traveling down the highway at 75 mph. All of the sudden the stabilitrak system light went on followed by the truck shuddering and shaking fairly violently followed by the reduced engine power light going on and a very quick reduction in speed to approximately 35-40 mph. Was able to pull over and tried to figure out what had just happened to a perfectly good running car. Attempted to reset the stabilitrak system using the gm manual page 5-6. No luck. Limped back onto the highway with a shaking truck with hazards on and made it to an exit . Went to gas station, turned off car again and filled with gas. Car was off for approximately 10 minutes while I ask for a gm dealership in town. Turned car on and the shaking had stopped and the power appeared to be normal. Went to gm. They hooked up to diagnostic machine . The code that came up was for a throttle position sensor replacement. Was covered under a special coverage adjustment, (12-6-2013) sent out to dealer service departments. Gm knows that this is a problem yet no one informed the drivers of these vehicles. My Yukon denalii xl was fixed . I am reporting this because I was put in a very dangerous position on the highway and high speeds. There is no doubt in my mind that without some good driving on my part and that of the 18 wheelers around me I could have caused an accident and injury. Once again gm knows this is a problem as stated in the #11273b special coverage adjustment- throttle position sensor replacement-December 16,2013. I would highly suggest that gm let car owners know so they can get the part replaced before killing or injuring themselves. I would not like my children or anyone else for that matter have this happen to them at any speed.
