Check Engine Light On problems of the 2005 GMC Yukon

While driving I hear a winding sound coming from wheel area while driving I smell fuel that comes and goes recently had full tune up now car starts to tick after a while of driving or even pressing on gas while in park it stops while driving car stalls and indicates coil is bad from check engine light being on I had changed coils and car still stalls.

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.

The contact owns a 2005 GMC Yukon denali xl. The contact stated that while coming to a stop, the brakes failed as the check engine warning light illuminated. Also, the contact mentioned that the power steering fluid would need to be replaced every six months. The vehicle was taken to a private mechanic where it was diagnosed that the power steering cylinder, the power steering hoses, the master brake cylinder, and the braking system needed to be replaced. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 85,000 and the current mileage was 98,000.

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.
