Passenger and both rear seat power windows quite working at the same time. This could possibly be a danger in case of an accident. I have found numerous complaints of this problem on 2000 Yukon. Throttle pedal sticks and you have to use excessive pressure to unstick it. This causes you to move forward or backward at a high rate of speed. This is an accident waiting to happen as you start off or are in a busy parking lot. Could cause injury to pedesterian or small child. I have also seen numerous complaints of this problem filed on 2000 Yukon. Passenger seat belt tightens as you ride to the point of causing pain, you must disengage seat belt and rengage to correct problem. This is also is a danger as you could be unbelted when an accident happens. I also have seen numerous complaints on this problem. There have been service bullentins on these problems, but GM refuses to pay the repair cost on our vehicle. They have been aware of these problems since these vehicles were in warranty. I purchased a 1996 Yukon new and had it until trading for this 2000 Yukon, I never had a complaint. Their quality assurance has sure gone down hill since 1996.
