While my wife was driving on the interstate highway at 55mph, the SUV check engine light came on, followed by a traction control warning on the display, then the vehicle went into "limp mode", reducing power and speed to approx 20 MPH. She turned on the hazards, and moved into the right lane as other vehicles went around her at the posted speed limit as the engine was bucking and missing. She exited the highway and limped the truck, barely getting up to 20 MPH to a service shop. They scanned the codes, the only one there directed them to change the throttle body, ($580). The vehicle ran good for 3 days, then all the same bells and whistles came back. Gmc service said they have no knowledge of a problem. Upon researching this online, I found it's far from uncommon. If this has not caused an accident yet, its only a matter of time..

2007 gmc yukon denali. As I was driving...engine light came on, following with vehicle stability control, traction control disable then reduced engine power and it wont let me drive more then 20 MPH. Took it the dealer, replaced terminal wires, replaced bcm module ($1100). Two days later same lights comes back on dashboard...took it to the dealer and they told me I need throttle body replaced ($631). Then even more issues came, as you stopping for the stop light, but the truck jerking forward while foot on break and as stopping it makes a thud noise when slowing down. Contact gm said they'll be able to help me out but then they decline for any help and simply told me there is nothing they can do. Now dealer is telling me I need breaks, ball joints, up control arms, shocks. Truck has under less then 100k miles and most of these should last more then 100k. Even dealer admitted by saying I've never seen yukon denali going back. Its a safely issue. My wife will not drive this truck any more with 3 kids in it and now it just sits in my garage while making payments to this truck. Its ridiculous! Im sure there are someone out there that can help us and others who are going through the same issue before gm get a lawsuit and have blook on their hands.

I had stopped at a 4 stop intersection. I took off and there was a sudden jerk, like I hit something or someone hit me. The car stopped suddenly, I tried to accelerate, the engine revved without acceleration. I put car the in park and back in drive, car did not move. I put it in reverse, had no problem going back but was in traffic and close to an intersection so it was unsafe to go back. Called "aaa" for tow. Cops came; they had me put car in 1st gear. Car was fine in 1st and 2nd gear. Drove car to parking lot. Cop stated that I had a transmission problem. Had car towed to gmc dealership. Next morning (may 7), dealership stated that it was a broken forward sprag but they needed to go deeper to see if there was more extensive damage to transmission. Asked how much, he said maybe 2000 to 4000. I called gmc home office and spoke with a rep. Let her know that my car was only 6 yrs old with low mileage and I didn't understand why I was having transmission problems. She called dealership and was told the same thing that I was told. At this point I didn't trust to deal with gmc so I decided to remove my car from the dealership. Received a call from dealership 2 hours later stating that they had authorization from gmc home office to offer me assistance of 40% off the total price. They said that it may be between 1500 to 3000. I had my husband call and they told him that if there was not extensive damage from the "broken forward sprag" it might be cheaper. Received call from dealership on may 8, no extensive damage, only replacing the "forward sprag". I am grateful for the assistance of 40% but I'm still upset that I have to repair the transmission on this car. It's not that old and I barely drive it. I've checked the web and have noticed other owners with similar problems. I was told to file a complaint with this agency and maybe it can be investigated.

Stabilitrack light and check engine light illuminates while driving down the highway. The car goes to idle and has no power to accelerate, almost got rear ended by another car. Once pulled over to side of road, shut engine down and waited 15 mins to restart. Stability track light and check engine light remains on and car accelerates normally. This has happened several times and is an extreme hazard! I have read numerous accounts of this happening to other owners of this model vehicle and dealer has no resolution to fix the problem, they just charge consumers for parts that are not really resolving the issue. This is dangerous for all drivers and will cause a fatality in the near future, something needs to be done!!!

Stabilitrack automatically shuts off at various times and signals on dashboard to get serviced. When stabilitrack is off transmission shifts very roughly and car lurches forward. Date of occurrence is approx but has been happening ever since.

Vehicle went into reduced engine power and crashed into fence. Vehicle goes into reduced engine power after 22 repair attempts and on highway at 70 miles per hour with children in car this is an extremely dangerous situation. My vehicle was damaged from the reduced engine power and at this point it is unable to be solved permanently to stop the vehicle from going into reduced engine power. It does it whenever and wherever without knowing. Goes from high rate of speed to zero. Almost had a semi slam into myself on the interstate. I could not pull over. Have had every part replaced and dealership is at a loss. Needs to be a recall due to inability to solve the problem.
