Automatic Transmission problems of the 2008 GMC Yukon

This needs to be looked at by gm. My uncle has a 2008 GMC Yukon xl 4wd. When it is put in park it will roll away on its own. We first noticed it about 3 weeks ago, but thought it had to been that it was on ice or something and it rolled about 40-50 feet back. Well last Saturday I was helping to unload groceries out of it with my mom and uncle. Just as I pulled the last bag out it rolled back. I seen the tires rolling. It almost ran me over, but I moved just in time to have it knock me on to my knees. Well the driver door was open and it caught me and dragged me about 40-50 feet. Well the tail gate hit me in the back of the head then the door got my arm pretty good. I am now going to the doctor for this. Today, we moved it to see what it would do and sure enough it did it right away as to where before it would take 15-20 min. It was just parked, with the emergency brake on and low and behold it rolled away again. When it drug me before, I got in it afterwards and it was in park. Not a driver error at all. I looked online and there are 2 other stories similar to this. Someone is going to get killed by this issue if it is not dealt with. If it would of run over me, I would of died and it came damn close. We are going to set up an appointment Monday to take it in. Is there anything you need to know, like where when and so on? it left me in pretty well constant pain from putting my back and neck out of place and my arm hurts all the time. So please look into this before someone gets killed!.

Vehicle has transmission defect. Merging into traffic is very dangerous. The transmission often selects too high of a gear and there is no power for the vehicle to accelerate. This puts the driver/passengers in danger due to oncoming traffic. After several seconds, the vehicle will sometimes downshift into too low of a gear, causing it to lunge forward at an extremely high rate of speed that is difficult to control. Happens all the time. Dealer and GMC have looked at the vehicle several times and refuse to fix the problem saying it is normal operation.

My 2008 GMC Yukon xl has transmission problems. Two separate dealerships have replaced the transmission seals twice. The car kicks back upon acceleration quite frequently, at all speeds. Three weeks ago, I was merging onto the freeway at about 45 mph and the car accelerated only without kicking into gear, causing another car to almost hit me. After about 15 seconds the gear finally kicked in really hard throwing my son and myself forward. It was very scary. I had the second dealership come and flat bed tow the car in out of fear of driving the vehicle. I received notification that the seals were lose and tighten and nothing else was wrong. One week later I am having the same issue. The vehicle is kicking back and sometimes does stops shifting into gear as I am trying to accel, the vehicle moves then it stops being able to continue. I am calling the dealership again today. I am wondering if there have been any other issues with this vehicles year, make and model. What should I do continue to try to resolve the problem with the car and take a chance of having something bad happening to myself and three children. This is really becoming scary and quite bothersome. I purchased this car for its safety and size and have to keep downsizing while this is being ineffectively repaired. What should I do?.

On all 4 occasions, the 2008 Yukon hybrid, lunges forward at low speeds, looses brakes, power steering and all power. Every time it has to be towed to the dealer. This has happened 4 times since August 2008. The first time there was a fire in the fuse box, then while the dealer had the vehicle, it caught on fire again. The dealer keeps telling me that it is fixed and safe to drive. The Yukon is back at the dealer and I am not taking it back. This vehicle is very dangerous and the government needs to look into this right away. I now have an attorney and we are contacting gm as well.
