2007 GMC Yukon Vehicle speed control Problems

“I will be driving and my truck will just lose power. I push on the gas pedal and it goes no where. I have to coast off the highway and then I can stop and turn it off for a few minutes then start it back up with the check engine light on. I have changed the tps 2 times, the entire throttle body, and the mass air flow sensor and it's still doing it.”

“Roughly 30 times since march my 2007 Gmc Yukon xl 5.3 slt has had the dreaded stabilitrack off, service stabilitrack, reduced engine power problem. You can be driving along at various speeds and the error will come on and you will be completely unable to accelerate. Leaving a very dangerous situation for my family. It has happened when pulling a camper and without pulling anything either. Gm refuses to help the many families having the same problems.”

“Happened two times yesterday. 2007 Yukon denali odometer: 191,707 engine hours: 1443.9 first, stabilitrak control turned off and engine power was reduced illuminated on the message center of the dash board. Car would not accelerate above 20 MPH. When I would try to push the gas petal there would be a shutter in the rear of the vehicle. I was able to put the car in park, turn it off and tried restarting. Same issues continued. I limped to my work a less than a mile away to try and figure out what was happening as I had myself and 4 kids in the car after trick or treating. …”

“There is cracks appearing on the dash all along the airbags housing compartment and part of the air bag is exposed . I'm very afraid that the airbag will go off while I'm driving because the dash is so cracked it's barely holding the bag in . I'm also worried it will affect the safety components and not work in an accident because of it being exposed to some elements due to the cracks. My vehicle has been garaged kept and always professionally maintained so it's not something we did or did not do I believe it's cheap material on the dash causing this to occur. …”

“My engine speed reduced abruptly while traveling speed of 65mph on the freeway. This has almost caused an accident several times. A reduced engine speed, service stabilization track and service traction control signs come on. If I pull over and wait 1 minute it starts and doesn't do again for 15 minutes. Sometimes this doesn't happen for a week. I read forums and it appears to be a faulty throttle body, and only with GM vehicles, but GM fails to request a recall. Some have spent hundreds of dollars to replace, and it still does not fix the problem.”
