general problems of the 2006 GMC Yukon

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.

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.

My stability traction control system engages in dry weather when accelerating from a stop, additionally, the system engages at moderate speeds which causes the vehicle to slow speeds in traffic. Also, the anti lock brakes engage in dry weather at slow speeds when braking. These situations have occurred on several occasions for the last several months.

The passenger side under dash bored caught on fire. Wile driving down the street it started to smoke and I saw flam. I was able to put flam out and lucky was a block from home. I parked it turned it off it seamed like the fire was out and no smoke . About 15 min later I go out side and my truck is in fire it burnt the whole in side of cab. I believe it was the moter blower that set on fire due to thats were fire came from . As well when I looked under the hood there was nothing wrong with it still perfect condition. So all fire damage I's completey inside SUV were the moter blower is .

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.

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.

The rear tailgate actuator quit working. The remote nor the key would unlock the rear tailgate. This quit working with no warning and no prior issues. Also the remote controls have had to be re-keyed many times. The vehicle was taken to the dealer and was the actuator originally replaced under warranty. I received a call from the dealer the next day stating the service adviser "made a mistake" and the $495. 00 was in fact not under warranty. This would indeed have led to very an unfortunate ending had I been driving and/or with passengers and an incident occurred. Now I read that many other GMC owners have been experiencing the same for months.

Broken, snapped off exhaust manifold bolts. Cause lean condition, and service engine soon light to come on.

Electronic stability control activates randomly. While accelerating from a complete stop the vehicle goes into traction control or reduced engine power. Stalling in the middle of intersections or at stop lights car behind expects you to move and you cant. You have to either turn car off and back on or put in netural to try and get your car to go this is a very dangerous problem that leaves you feeling helpless and no control of your vechical I pray that this is looked into before someone gets hurt I also reported this to GMC.

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. Thanks, steve.
