Yukon 8-cyl

  • 120,000 miles


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.

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. The problem is fixed for now, however, after researching online it seems like there are hundreds of GMC Yukon owners experience very similar issues with their vehicle's engine. I keep reading about the "reduced engine power" and "service stabilitrak" warnings.

Vehicle gets extremely low gas, 13 mpg on average. Burns oil. Need to add 2-3 quarts of oil between oil changes. Engine cooling fan stays on for extended periods while driving. All of which the dealership says is normal for the truck. They removed the driveshaft because of clunking at 25K mi. Reaction carrier replaced and transmission reconditioned at 36,663 mi after car stopped in the middle of the street. Car had to be towed in. At 62K miles engine light on and idles rough. Replaced throttle body. At 67K won't engage in reverse and makes clunking sound from reverse to drive. Replaced reverse housing, reaction shell, etc. At 75K had a reaction carrier failure, lost power brakes and lost power to the car. Almost was rear ended. Had to stop in middle of parking lot during christmas rush. Waited 5 min and restarted. Engine light stayed on, but was able to get to dealership. Was told that throttle body needs to be cleaned every 15K miles under service maintenance. This was the first time I heard this! not really sure why it had to be cleaned, though, just had the throttle body replaced 13K miles ago. It seems that there are major flaws in the design of the engine. Obviously, the dealership has been putting band aids on my problem because they don't know how to fix. I have been very lucky that my family and children have not been in a major accident due to the major flaws in the engine designs. Every time I get my car fixed, the tech assures me that they have fixed the problem. I am really afraid to drive this car with so many close calls. The car is a hazard to drive!

I placed the shift in park, stepped out of the car (it was dark about 10pm) 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.

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 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. Mechanic noted that the previous dealer that worked on vehicle might have not tightened bolt correctly since bolt had no damage of threads and was intact. I then called GM customer service and they refused to correct problem. Service director did mention that axles could have shot out and caused fatal crash keep in mind my daughter of age 6 was in the car.dealer (home dealer) still has vehicle and dealer that last repaired refuses to correct problem. It has been 1 year and 1 month since last repaired and mentioned if not tightened properly it would have already caused problem by now. Please advise if I have any alternative course of action the repairs exceed $5000 dollars not including any damage to the transmission when drive shaft locked...

My name is mario moreno, I reside in tucson AZ, I own ad my wife and I drive a 2007 G M C Yukon slt, my concern is our Yukon seems to lunge at times, what I mean is, when we stop our S U V at stoplights, stop signs, or pulling into our garage the RPM raises to what I feel is an unsafe levle.which requires us to apply the brakes in a manner for which I and my wife feel is excessive pressure being applied to the brakes. We have expressed our concerns to our local G M C dealership more than five times in a one year time frame. Their responce is we and our techs, can not duplacate the issue we have expressed! we both feel this is an unacetpable responce. I know that the system inolved is non mechcanicle system that opperates the gas peddle it opperates the the accelorator peddle by the use sensors and or sending units.please advise. Im we are very concerned about oue familys saftey.yours truly mario moreno P.S thank you for your consideration
