i have a 2000 yukon slt with just about 70,000 miles on it and am very, very happy with it but have a few probelms. Problem 1: every time you fully let off the gas pedal and push back down on it, the pedal "sticks" Its not that i have to almost kick it to get it to move, but its enough "stick" there to be annoying. I played with the pedal the other day and it stopped doing it for a few days but today i noticed it was back.. problem 2: Whenever you open either of the rear passanger doors(not cargo doors) they squeek very loudly and its is very annoying. I looked at it the other day and it seems the top part of the door it rubbing against the weather stripping causing it to squeek. Problem 3: whenever you press down on the brake pedal with a decent amount of effort you hear a weird squeeking/creeking noise which is also very annoying. The sounds is unexplainable, youd have to hear it to understand what i mean. any suggestions?
