Failure Date: 06/12/2015

While sitting idle my vehicle suddenly went into reduced engine power mode. I was able to get over and pull off the road and shut off the car. 5 minutes later the car started like there was no problem. Over the next few days the rep warning would show up and my car would suddenly lose power. I was crossing the road during one incident. However, when I would shut off the car and restart the check engine light would go away as would the rep warning. After a quick review online it is easy to find hundreds of people who have a similar issue. Gm will only diagnose and if the light is off when you get there there is nothing for them to do except take your money and say good luck.

While driving on the highway with my cruise control set between 50-70mph, I began noticing my speedometer beginning to jump between 0-120mph causing the limiter to kick in and me losing the ability to control speed. Keep in mind I'm only going between 50-70mph. This later began occurring without the cruise control on. Shortly after this began happening another problem started. Now when the cruise control was set between 50-70mph, the engine would automatically accelerate maxing out the rpm's and sending the vehicle to approximately 80-90mph before I had to hit the brakes or completely cut off the cruise control. Later on when I would set the cruise control the vehicle would begin to jerk violently, revving high then going back to normal before revving high again and me shutting off the cruise control. There was never a check engine light the whole time this was happening. I immediately took it in to the dealer I purchased it from, randy marion GMC in huntersville, nc, to be checked. I was told that I had a bad mass air flow sensor. That was replaced but the problem was still occurring. I took it back a second time and they could not find anything wrong so I began reading blogs to see if anyone else has had this same problem. Some had similar issues and said the ignition coils may be bad. I had those checked and all were good. This vehicle has never been in an accident and I am the only owner. I've contacted gm, general motors, about this and was told that there were no recall issues but have yet to have my calls returned by the person handling this case. This vehicle is not safe and no one seems to be listening.

While traveling on the interstate at speed (70) the stabilitrac light came on and reduced engine power message displayed. The rpm's went over 4k, then the Yukon slowed in traffic and I had to pull to the side before being run over. The accelerator was unresponsive at that time. I turned off the engine, waited about 5 minutes and then resumed driving using '3' to engage transmission instead of 'd' the check engine light remained on, but I made it to my destination 2 hours away.

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. .

When the car is at idle in drive it becomes very rough (fluctuates up and down). This happens on and off and I have no check engine light on. Sometimes the car even feels like it is going to stall out. I have had it into the dealer and they admitted they feel it as well. They tried adjusting the motor mounts and that did not do it. After having in the dealer for several days they called me and said they can't find the issue. They told me they went into another 2015 GMC Yukon sle and started feeling the same issue. It was stated to me I might have to wait for more complaints on the vehicle to get to the root of the issue. It continues to idle roughly and I want to get this resolved.

My 2008 Yukon xl is giving several error messages. Traction control off, service stabilitrac, check engine light remains on even after I've replaced the throttle position sensor, coil pack, full tune up nothing seems to fix the issue and I see that I'm not the only one experiencing this issue. Any insight on resolving this problem would be gladly appreciated it is also using more oil than usual.

As I was driving 'oil pressure is low, cut the engine off' warning came on and the oil light was on. That also triggered the traction control/stabilitrak light to come on. From then on whenever I drive the vehicle those lights come on as well as the check engine light. This is apparently a common problem with the GMC 2007 engine. There are multiple forms from chevy, Cadillac, and GMC where consumers that have these engines are experiencing this problem. When we take it to dealerships we are told to change the engine. I was just quoted over $8000 to change this engine. I can't even sell this truck without losing my shirt. We need help out here. Gm knows that this is a problem because the dealerships know. They are sweeping this under the rug until some people die because of it!.

Failure Date: 04/10/2014

Driving 40mph in traffic and the engine turned off by itself, no power steering or brakes at this point, I was able to stop the vehicle in traffic and put my hazzards on while I tried to figure out what happened. The vehicle was acting as if it was still on and would not restart, I still had power to everything and the dashboard was displaying several error messages. Stabilitrack, traction control and engine reduced power and also the check engine light was on. Vehicle would not restart. After about 5 minutes the vehicle restarted and I was able to drive off, the check engine light stayed on for 2 days. This same exact occurence has occured again this time on 4/27. It also happened while parked on 3/1 with the engine running. I am having the vehicle serviced at a GMC dealership in carrollton texas today.

Intermittently at hwy and side road speeds, truck will shut down, check engine light comes on and extremely rough idle and loss of engine power occurs. Have followed all recommended fixes but problem persists. Engine code 1516, throttle position sensor out f range +- . 05 volts. Scary problem, as this occurs without warning and causes immediate loss of speed. Many many complaints posted on the internet of this same problem but no GMC recommended fixes or assistance. Refuse to take this to a dealer and let them poke around at $95 / hour and or to throw parts at truck in hopes of correcting. GMC needs to address this potentially fatal problem.

I was driving approximately 65 mph uphill when my engine and traction light came on. My speed was immediately reduced to about 35 mph even though I tried to accelerate. I drove home about 8 miles at a reduced speed because I had my children in the truck and it was raining. I took the truck to a mechanic the next day and he replaced the throttle body. I picked up the truck that evening and as I was driving home the same thing happened again. I took the truck back to the mechanic, the check engine light and tc light was on again however he said that there was nothing wrong. His thought was to replace the throttle body again. Two replacements later, the problem remains.

On July 26, 2013 I was in my 2007 GMC Yukon denali when I had an issue. I was in my car, the engine was running but it was in park. I was idling for about 5 minutes when I received a "engine power reduced", followed by the check engine light. I immediately shut the car off and gave it about 20 minutes before I turned the car back on again. The check engine light was still on with the "engine power reduced", followed by "service stabilitrac", "stabilitrac off", service traction control", "traction control off", and "power assist off". I immediately called the local GMC dealership and they told me to try to bring the car into the dealership to see what they could do. After I brought my car to the service department I was told that the sensor behind the gas pedal needed to be replaced. They replaced the part for roughly about $300 and the check engine light went away with all of the messages. Since the repair I drove the car for about 60 miles and the check engine light did not come on again, and the car seems to be fixed. Please look into this matter since there are quite a few of us with this same issue.

I was drving my vehicle. The traction control light came on, and the check engine light came on right after. The truck then began to idle strange like it was going to stall. I drove it home while talking to my husband he stated since I just filled up the tank maybe it was bad gas. I drove it home which was about 5 miles down the road. As soon as I pulled into the driveway , the service brake system came up on the dash and the my truck started making this horrible clicking. I later found out the motor is gone and threw a rod. I think its pretty odd that all these people are having issues with the traction control light coming on then the engine acts up. This is a problem GMC needs to fix, they dont feel its their problem to deal with.

The "stability control disabled" sensor comes on followed by "reduced engine power" and my vehicle won't go faster than 5mph. This has happened at least 6 times in the past several months only upon start up of the vehicle. Sometimes, if I wait a couple of minutes and restart my car, it'll start just fine but the check engine light comes on. I first brought it into hendrick Chevrolet on 10/15/12. They charged me almost $700 to replace "app sensor assembly". Then I brought it in again on 11/6/12 for the same issue. They replaced the "connector at the throttle body" and charged me $223. 09. The issue temporarily went away. I then brought it back on 12/20/12 with the same issue but this time the check engine won't turn off as a result of the reduced engine power-stability control disabled warning. They simply reset the warning and that was it. Til this day, I continue to have problem with this vehicle going into reduced engine power/stability control disabled. This has become a constant issue and thorn on my side and each time I bring it in for service, they always tell me it's something else. I have read many of the same issues other owners have had. Why haven't there been a recall on this???.

I was driving the vehicle down the road doing 65 mph. The engine light came on and the message appeared that stated "engine power reduced" "service stablitract" "traction control off". The car lost all power and I was unable to go over 20 mph the rest of my trip home. I went from 65 mph to 20 mph in seconds, on the interstate full of traffic. When I got home I then noticed a "hot" smell. I then had the car towed to a mechanic.

While driving from GA to la on christmas eve, my Yukon xl went into reduced engine power and lost traction control and antilock brakes. The car almost instantly dropped from 72mph to 45mph and the check engine and traction control warning lights came on. I was advised by onstar to pull the car over and turn it off for a few minutes. When I started it again, power was restored, but the check engine warning light remained. I was advised that the car would probably do the same thing and that I should have it serviced immediately, on the next business day, which was Monday December 27th. While driving to a destination about 30 miles away on Sunday, the car went into reduced power again and the warning lights returned. This time turning the engine off for a few minutes did not help and power reduction remained. I took the car in for service first thing Monday morning and was told that the throttle body assembly was bad and had to be replaced, but that the part was backordered at the factory, so my vehicle could not be repaired. I called my dealer in GA to see if they had the part, but they also had two on backorder for two other customers. As a result, my vehicle, which is only a year old and under warranty, cannot be repaired and is unsafe to drive on the highways. The sudden loss of power could cause an accident. After checking online complaints about this issue, I discovered that many people driving gm vehicles are experiencing the same 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.

Ever since I bought it in oct 2004, I felt this jumping of the truck after I stopped and started to accelerate it would do this, I called in and they told me that maybe because it was new, it may be doing that , I took it in last week because the engine light was lit and there was a strange burning smell on , it and there was also the recall of the back seats, and a light sensor loose, it was returned to me after a few days, and they said that it was because the gas cap was loose? that was the worst excuse that I have heard, I am still having that problem, but I just don't want to take it anymore because they are going to come out with the some lame excuse , and still have the problem.
