This is the 2nd GMC Yukon with a faulty drivetrain I've acquired in 3 years. Both occasions were directly after the vehicle had professional service done related to the faulty system. The transmissions was fully serviced at reputable repair shops and within a month or 2, without warning, the transmissions started having mechanical issues without DTC being triggered. As well as a 2004 Buick Rendezvous with less than 70k miles on it. The 2001 GMC Yukon suddenly lost reverse and park while driving and imploded the transmission in the process. The 2004 Buick Rendezvous started slipping and ceased to move by it's own power when at operating temperature. The 2006 GMC Yukon Denali stopped shifting gears while on the freeway at 55 mph and systematically lost all moving gears within a day also while at operating temperature.

Equipment: other: labels
- What is wrong
- Certain trucks and sport utility vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 110, "tire selection and rims." these vehicles were shipped with tire and loading information labels listing an inacccurate vehicle capacity weight.
- Risk
- A misprinted label could lead to improper vehicle loading specifications or tire inflation which could result in a tire failure, increasing the risk of a crash.
- Remedy
- Owners will be provided with corrected labels and installation instructions. At the customer's option, a dealer can install the label for them. The recall began on march 31, 2006. Owners may contact buick at 1‑866‑608‑8080, cadillac at 1‑866‑982‑2339, chevrolet at 1‑800‑630‑2438, gmc at 1‑866‑996‑9463, hummer at 1‑800‑732‑5493, pontiac at 1‑800‑620‑7668, saturn at 1‑800‑972‑8876, or isuzu at 1‑800‑255‑6727.
Recall number 05V552000 · Recall details
Steering: hydraulic power assist: hose, piping, and connections
- What is wrong
- Certain passenger vehicles may have been built with a power steering hose that is not to specification. Under extreme steering maneuvers, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid.
- Risk
- If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were to spray onto hot engine parts, an engine compartment fire could occur.
- Remedy
- Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required. The recall will begin on october 14, 2005. Owners may contact chevrolet at 1‑800‑630‑2438, gmc at 1‑866‑996‑9463, buick at 1‑866‑608‑8080, cadillac at 1‑866‑982‑2339, isuzu at 1‑800‑255‑6727, or hummer at 1‑800‑732‑5493.

What 2006 GMC Yukon owners say
Most recent owner complaints, unedited.
The Brake lines are not coded so the brake line rusted and when brakes got applied they burst causing accidents for no pressure and can’t stop. Air bags light stays on and will not go out. I have put new lights bulbs in truck but lights are still dim.
Driver side steering wheel safety air bag defective, warning light on dashboard says not functioning. Nervous about driving vehicle if there is a collision. Gas gauge misreads fuel level and check engine warning light keeps coming on. Ran out of fuel a few times. Has been checks problem keeps coming back on both.
It happened repeatedly now while driving on freeway the steering would get sloppy at random moments and keeping the vehicle in its lane becomes difficult. I replaced tie rods inner & outer, upper/lower ball joints pitman arm and idler, swaybar links shocks/struts. I even had two different mechanics look at the steering components. Both said everything is in good shape. This only happens at freeway speeds. I bought this truck a month ago
Airbag failed function due to lack of inflator performance during my husbands head-on crash and he suffered collar bone and rib fractures,massive head trauma resulting in a crainiotomy,brain damage and death one month later. The vehicle was travelling at 45mph on a paved two lane street.
Tl* the contact owns a 2006 gmc yukon. While accelerating from a stop light, the vehicle failed to accelerate when the accelerator pedal was depressed. The traction active warning indicator illuminated. Also, when making turns, the steering wheel made an abnormal noise. The vehicle was not taken to a dealer or an independent mechanic for diagnostic testing. The manufacturer was not made aware of the failures. The approximate failure mileage was 101,000.
Known problem, brake failure due to rusted brake lines. Nearly had a rear emd collision when they failed trying to stop at 50 MPH. A large truck was disabled in the middle of the road. I swerved into the left lane, since I couldn stop.
My vehicle was in motion driving on the freeway at 70 MPH when all of the sudden my car lost power to 30 MPH all the way down to 5 MPH.I pressed on the accelerator trying to gain speed without success the car did not accelerate more than 30 MPH, no matter how much I pressed on the accelerator. When I looked down at the dashboard I saw two warning lights go off "stability sys disabled" followed by "reduced engine power" luckily I was able to move to safety. The road was dry and no bumps to disable stability. The traction control in this vehicle is located far from my steering wheel so I know I did not accidently hit the traction control by accident. After I was able to pull over I was advised to hit the traction control button to see if that would fix the error in the dash. That did not work. I immediately took it to the dealer concern for my safety and that of my family. The dealer has had my for several days returned my car back once stating that it was due to master air flow sensor along with the air filter once those parts were replaced I picked up my car as soon as I picked up the car and drove it around the corner I experienced the same issue. I drove it back to the dealer at 5 MPH as I was not able to go any faster no mater how much I pressed on the accelerator. 2nd time the car was returned to me I was told it was just the butterfly in the throttle body and that it was replaced for a new one. I was driving away and got just a little farther than the first time when I got the same error message again I drove it back to the dealer and they told me it was a faulty throttle body they replaced that but its still having issues. I believe this to be a safety hazard while driving I want this noted in case there is a major accident with fatalities.
Bonddogbonddog august 2006 edited june 2015 in gmc I purchased my 2006 yukon last september 2005. I now have 24,000 miles on it. Over the last month I have had it into the dealer three times for the same problem. The problem is that while driving the vehicle it will suddenly lose almost all power. The information center will display the messages: "stability control disabled", "engine power reduced". And the vehicle will not go over 20 MPH on a level surface and bearly 3 MPH up a moderately steep hill. Each time I have had it into the dealer for repair they have beeen stumped by what the cause of the problem is. They said that gm/gmc told them that "gm is aware of the problem but does not have a fix for it at this time". How can a manufacturer sell a vehicle that has a defect and not have a fix for it? When the power goes out in a busy intersection or on a highway this is a major safety issue. Has anyone else experienced this problem.

I'm having a problem with my right front tire hub being damaged noticed a recall however when I looked at my VIN number it did not come up. Can someone please look into this as it is very costly for me to fix and I'm not the original owner so therefore I would like to find out if this hub problem with axel was ever fixed I also had a problem with the gas line in the past and noticed there is a recall for that which I did not have listed under my VIN number either can someone please write me back and let me know if this is something that would be covered. My tire is in the midst of falling off I continuously get a notice to check tire sensor in addition I have had several electrical issues including the fan not working inside the vehicle to turn on the heat or air conditioner
