2007 GMC Yukon Denali: check engine light

Filed Aug 21, 2017 · Driver assistance, Electrical · 150,000 miles · LA

Instrument panel is going out, one instrument at a time. First showing low oil pressure, stabilitrak warning, check engine, now it is the RPM gauge that isn't showing anything. Also have a huge crack in the top of the dashboard that's been there for about 5-6 years. I've seen online complaints off this issue.

When driving down the road the engine light in my denali comes on and engine power is reduced to a slow speed where I have to pull over and shut the vehicle off. After doing so for 5 minutes or more, I cut my vehicle back on and it will drive normally with engine light still on. It has done this numerous times, sometimes 5+ times in one day. I have tried taking it and getting it fixed but no gm dealer can figure out the issue. This is unsafe especially when I am driving much less with my family in the car with me. Please help me get this issue fixed gm doesn't seem to want to fix their issue.

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!

This has now happened several times since, at no particular speed. I will be driving and all of a sudden the stabilitrak lights and traction control lights come on, and the engine begins to run very hard and will not accelerate very quickly and cannot reach full capacity. This is somewhat scary as it has happened on the highway several times, as well as just driving around my residential area, always with my kids in the car. Usually once I turn the car off and leave it for a little bit, then restart it, the lights are off except the engine light will stay on. It seems to me that many people are having the same issue with this model and that gmc should be taking this safety concern very seriously as not being able to accelerate on the freeway is definitely a huge safety issue.

Front left exhaust manifold bolt head broke off. When the engine is cold upon startup exhaust gases escape near a water temperature sensor. Which could make the engine light come on and not pass inspection or cause a fire.

Having alot of issues with traction control light coming on and off causing my truck to either shut off/stall or just not turn on than the check engine came on arggg. I took to dealers was told its my throttle sensor got it replaced $$750.00 ughh then it happened again and then when I try and turn it on again it will flash traction light on and off so I turn it off then turn it on and it goes away, later comes on then off random times I checked this site since I seen news and seen other people having the same issue. And my cruise control wont kick in also my front dash has cracked on top of the odometer and it does make me worry if I ever get into an accident will the dash shatter completely?? Other then that I love this truck really I do !! However dear gm stop being stingy and pay for your mistakes!

It began w/a harsh shift from 2nd to 3rd. It started happening more often, my engine light came on& it began shifting so harsh it would jerk you. Went to my gm dealer & the code was for a throttle body sensor. They replaced the sensors & also found a cracked motor mount. They advised the crack was probably due to the transmission shifting so harsh, also the shifting problem was probably due to the sensor malfunction and the lack of communication from the throttle to the transmission. They replaced the mount & sensors. Charged me $700. Left the dealership, 15 mins later the engine light came on! I took it straight back and days later they called...couldn't find anything wrong, the code again was for the sensors, they installed again & checked the solenoids but they were fine. They advised a new transmission was needed & would be $2400. With no warranty, I couldn't afford the repair, so I have been driving it until I came up $$. It still shifts horrible and often 'revs' while accelerating but won't shift from 2nd-3rd. The engine light comes on, I have to pull over, turn it off 20 mins before it will drive. A day or two later the engine light will go off, but will randomly appear again when the 'no go' happens again. After 'googling' the symptoms, there's several forums stating the exact same issues! I'm afraid this will happen while merging on the hwy or at an intersection. This is the most expensive car I've owned & I'm in shock a vehicle that cost me 50k would end up the worst car I've owned. The transmission is the only safety issue I have, but since I've had the car, I've replaced 3 door handles, it shakes around 60mph, the back passenger door won't open from the outside & the locks intermittently work, both caps on the aux outlets came off after 6 mos along w/ the paint on the A/C controls. Completely disappointed in gm!

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.

Traveling on I-75 northbound from chattanooga to knoxville, the speedometer goes to zero, car reduces speed almost to a halt. Off to the ramp at really slow speed. Check engine light comes on, and soon after the traction control light. Computer indicates: service stabilitrac - service traction control - power assist off - transmission fluid hot, idle engine. Removed the battery cable for 5 mins. Car restarts but all the lights and messages still on. Returned home (about 35 miles) with engine revving around 3500 and speed at about 50 MPH. Engine temp and oil pressure indicators ok. This was scary with 2 kids in the car! Taking it to garage tomorrow.

I was driving 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 don't feel its their problem to deal with.
