I had just left the free way went onto a 2 lain road we were driving about 50 mpr then we lost engine power,all the dash lights came on ,we pulled over the car killed,didn't know what to do ,so we waited a bout 8 minutes then turned the key, the car started and we went on our way,a few minutes later it did the same thing, it did it 2 more times, took it to the shop was told it was a gas tank sensor ,$500.00 stoat at the shop,and the car still has the problem,what happens if the engine reduces power while do 65 mpr down the free way, ? I think we have a big safety concern here, and gm needs to know, if they don't all ready know...
2007 GMC Yukon Denali electrical complaints
Page 2 of 2: complaints 11 to 16 of 16, newest first, as owners wrote them.
Wiring to rear window defroster became detached at soldering connection. Was told entire rear window had to be replaced. Yukon was still in warranty.
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!
I have just read a few other complaints about an issue I am having now, and have had 3 times in the past. While under normal driving conditions, I have had my SUV become very sluggish and difficult to drive. Lights come on say loss of power, stabilitrac problem etc. The first time this happened, I was visiting orlando florida. I took the SUV to a dealer, and they said there was an issue with the ECM and reprogrammed it. I left back the next day for atlanta. Nearly 80 miles away in ocala florida, it started doing this again. I called a tow truck, and had it taken to an ocala dealership. They in turn told me it was a bad ECM, and after spending an entire day in ocala, I was back on my way to atlanta. Several months later, I had this occur again. Once again I had it taken to a dealership in atlanta. They ran a computer diagnosis on it, and said they had no idea why it was diagnosed as an ECM problem, as the code coming up was due to a problem with the sensor in the floor board that reads the distanceof the gas pedal from the floor board. As it is a drive by sensor vs drive by wire. They repaired this, and although I felt it should have been covered under warranty, even though I was out of warranty at the time, the first two incidents that were supposedly diagnosed wrong were done so while under warranty. They ended up cutting the costs in half. I had no choice, as I needed my vehicle back. Now it has occurred the forth time. I have resorted to the internet to see if other are having the same problem. What I'm finding through this research, it sounds as if many have had the same issue, and it seems to be an issue with the throttle body. While researching, I was alerted to this site, thus the reason I'm posting here. Maybe something can be done about this issue, as it seems this happens quite often, and gmc is keeping it under wraps.
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.
