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. …

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..
Tl* the contact owns a 2007 GMC Yukon. While driving, a loud knocking noise was heard from the engine compartment. In addition, the traction control, engine, and stabilitrak warning indicators illuminated and started to flicker. The contact coasted the vehicle to the side of the road and the gear shifter failed to move into drive. The contact had to drive the vehicle in low gear to his residence. In addition, the vehicle made a loud noise while idling. The vehicle was later towed to an independent mechanic who stated that, due to hard shifting, it failed to drive and the transmission needed to be replaced. The vehicle was repaired. The vehicle was not taken to a dealer. The manufacturer was notified of the failure and informed the contact to take the vehicle to a local dealer. The approximate failure mileage was 200,000.
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.
2007 Yukon goes into reduced engine power on a regular basis. As a result, there was a crash on one particular incident. On a daily basis, it continues to and the engine cuts out as a result as well, no rhyme or reason. On the interstate, going 70 miles an hour the vehicle cut off, went into reduced engine power and myself and my family were just seconds short from losing our lives. This has all been reported to GM and we've gotten no resolution. Motherboards, gas pedals, gas caps, wires, everything you can think of has been replaced on my vehicle and it still goes into reduced engine power putting my families lives at risk. This is an extremely dangerous situation.

I placed the shift in park, stepped out of the car (it was dark about 10 pm) and was imediately knocked down. The car backed over both legs and into a ditch. I hit my head and was unconcious for 15-20 minutes. I am recovering slowly. I am sure I put the car in park-at least I thought I did.
I purchased a 2007 Yukon and since that time I have had the rear axle bearing replaced 2 times at 43K miles and again at 93K due to a humming noise extremely loud. Again the noise recurred at 123K miles I returned to dealer they refused to diagnose the problem because the warranty was expired at 100K. I mentioned that the noise returned for the 3rd time. Ii continued to drive the vehicle and a few days later while driving on the freeway w my daughter the car locked ( differential). The differential gears broke..I had it towed back to the last dealer that repaired vehicle and they mentioned it was out of warranty ( which is why they couldn't inspect it unless I paid). I then took it to my home dealer where car was purchased and they discovered an intact screw when they removed the cover from differential. …
I noticed an approximate 4'' crack on my dash between the windshield and steering wheel hump. I then noticed a similar crack emerging near the top left portion of the front passenger side air bag. I thought maybe the employees where I get my car wash were applying too much pressure. However, after looking online to buy a new dash, I found that I was among many GMC owners that have the same issue. I dont think it is a coincidence that we all have the same cracks, in the same location on the dash. Also, the chrome plating on both my driver and front passenger inner door handles is peeling off. I heard that exposure to the sun May be a cause, however, my two front windows have had 5% tint on them since I bought it. Also, I just got my vehicle back from the dealership because of check engine light issues. …
