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.

My husband was driving and the tracking and stabilization light came on. The truck turn off in mid traffic. It did start back up and we took it to GMC dealer. They have had it since. The dealer still has the truck and has fixed three different things and my bill is increasing, but they have failed to find the problem. This is a danger to myself, my husband and our two children. I have called GM and they are pretty much like stay in contact with dealer.

GMC is currently admitting to faulty ignition switch failure. When I purchased my vehicle three years ago every year this has been an ongoing issue filed a complaint last year in 2013 never heard back from dealership. Dealership has been fixing issue but not taken care of it properly. Looked at recall list but the 2007 GMC Yukon was not included. Can you please advise?

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.

The approximate failure mileage was 63,000.

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.

I was driving on the expressway at 70 mph and the car completed shut me down to 50 mph in a matter of seconds the check engine light came on then the service traction control, traction control off, service stability track, stability track off. I took to the dealer and had over $1100 worth of work done including the throttle body. Here we are 5 months later and I am on the expressway car shuts down again and the same warning signals, check engine light, service traction control, service stabilitrak light comes on again. I also have a problem with oil consumption barely make it 1000 miles on a new oil change when the check oil light comes on, when you check the oil there isn't even any oil on the stick.

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.

Was driving down the freeway and the vehicle warning bell rung. On the vehicle heads up display read. Traction control, stability control and reduced engine power. The vehicle immediatly started shutting down with no power. This caused a near miss from behind from a tractor trailer vehicle.

"reduced engine power" message while driving on the highway at 65mph. My truck immediately dropped down to 35 mph and nearly caused a wreck.

I purchased my 2007 Yukon about a year ago, in that time the stabilitrak light/check engine/traction control has come on 2 times now. The stabilitrak light comes on and check engine light also comes on it tells me it is turning the stabilitrak off and beeps at me. Both times this has happened I have called my mechanic and he told me it is fine to drive to bring it in later and he will hook it up to the computer. The light stays on until I arrive at my destination, I turn the car off let it sit and come back later and it is off when I restart it. I have had the mechanic hook it up to the computer two times now and nothing shows in the history. He has called around to the local GM dealerships and no one knows anything about it. I would like to get this resolved before our extended warranty is up.

Serious safety issue please read, research and address!!! 2007 GMC Yukon 4X4 my stabilitrack light comes on then engine power flashes and I loose power ongoing problem! I was doing 70 mph down the freeway when this happened fortunely no one was behind me serious safety issue! I have had it to the dealer X2 two months ago. At first they cleaned the throttle body but could not pin point the problem. The second time I had it there they again could not find the problem. I have researched this online and this is a common problem. No real conclusive answer to why. There needs to be an investigation as this is a serious safety issue!! I am taking my vehicle to another auto mechanic. My vehicle has about 140,000 miles however this proble began nearly a year ago but it did not reduce engine power. The problem fixes it self if you shut the truck off and restart. Please address!! [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

2007 GMC Yukon slt...stabilitrak failure. This error has popped up as we are operating the vehicle around 7 times. It shuts down and reduces the power to the engine so that the car does not have enough power to get to a safe place out of traffic. Imagine driving at 70mph and the vehicle suddenly loses power and you have a massive big rig closing down on your tail with no power to get out if the way! imagine climbing a hill with the vehicle power suddenly reduced with a big rig trying to climb behind you and you have no where to turn off for safety. I am extremely disappointed in this vehicle with only 127614 highway miles on it. The vehicle was repaired with a differential problem with only 65,000 miles on it.

The check engine/service stabilitrak/engine power reduced light comes on frequently yet the GMC dealer cannot pinpoint the problem. Potentially a connection to recall of cars equipped with heated windshield washer fluid feature. Did detect a slight odor shortly after using the windshield washer fluid and the indicator lights started flashing and the car slowed down considerably on the highway during inclement weather. Thus far nothing has corrected the problem; we are hoping to get the car back to our home state so the dealer can work on resolving this hazard.
