 The stability control disabled sensor comes on followed by reduced engine power and my vehicle won't go faster than 5mph. this has happened at least 6 times in the past several months only upon start up of the vehicle. sometimes, if i wait a couple of minutes and restart my car, it'll start just fine but the check engine light comes on. i first brought it into hendrick chevrolet on 10/15/12. they charged me almost $700 to replace app sensor assembly. then i brought it in again on 11/6/12 for the same issue. they replaced the connector at the throttle body and charged me $223.09. the issue temporarily went away. i then brought it back on 12/20/12 with the same issue but this time the check engine won't turn off as a result of the reduced engine power-stability control disabled warning. they simply reset the warning and that was it. til this day, i continue to have problem with this vehicle going into reduced engine power/stability control disabled. this has become a constant issue and thorn on my side and each time i bring it in for service, they always tell me it's something else. i have read many of the same issues other owners have had. why haven't there been a recall on this???

 While driving on interstate traction control lite came on in dash then power to suv was lost then electronic message read out stated stability control disabled then reduced engine speed message appeared. i was able to pull off interstate but nearly got rearended hit by semi. engine would run only at idle speed. after shutting off vehicle and waiting minute or two then restarting it ran fine. this has happened numerous times since then. speeds vary 70,55,40 mph it doesn't matter. after calling different gmc dealers about problem they act like this is something they never heard of.bull**** !!!!. its the same problem numerous gmc owners are facing on the internet. gmc customers have spent thousands of dollars with no problems solved. all they want to do is hook you up to electronic machine and overcharge you for the same thing autozone ,etc. businesses will do for free. i don't have thousands of dollars for them to be parts replacers . gmc should know the exact part to fix this problem. someone or family is going to get hurt badly if gmc doesn't fix this problem they know they have. *tr

 While in the middle of driving, the stability control diasabed sensor comes on folloed by reduced engine power and my vehicle just shuts off. i have been fortunate the 4-5 times it has happened as i have been able to pull off the road, wait a couple of minutes and restart my car. i have already replaced a hub that my mechanic said was causing a traction control problem from earlier. i am reading online all of the nightmares and i unfortunately do not have thousands of dollars to keep trying to fix an issue that gmc is clearly aware of. i have 5 kids and frequently drive them around and someone is going to get hurt and i think gmc should take some responsibility.

 Dt: vehicle is a 2004 gmc yukon denali. while driving 25-35 mph the vehicle will shut off on the consumer. this problem has happened twice in the same day, which was on 6-24-05. the brake light will come on then the vehicle loses all power. the consumer can get the vehicle to stop by applying extreme pressure to the brakes. the first time it occurred while consumer was stopping at a stop light. less than 5 minutes later she was able to get the vehicle to start again. afterwards she was pulling into a gas station when the vehicle shut off the second time. the consumer had taken it to the dealership the same day. the vehicle remained there until 7-2, and at this time they told her that they could not find a problem with the vehicle. the third time the vehicle shut down was on 7-3. this occurred while the consumer was driving 30-35 mph. the consumer had taken it back to the dealership on 7-5. this time they replaced the crank shaft position sensor. the consumer picked the vehicle up on 7-11. and today 7-12 the vehicle started shaking and jerking while going 60 mph. this problem was off and on until the consumer had stopped the vehicle. after starting the vehicle back up and driving 35-40 mph it stopped on the consumer for the fourth time. and as of now the vehicle is at the dealership. all repairs were done by the same dealership as purchased from. the vehicle is still under warranty. as of now the consumer has not contacted the manufacture. *nm

 Exhaust system on my new 04 yukon denali has an excessive amount of popping and cracking noise after it is turned off. i had an 03 denali prior to this and it did not do this. this has gone on since i got the vehicle. dealer says there is nothing they can do about it.*ak
