Rolled down front passenger window using the driver button and was down for about a minute and then as I tried to bring it back up with the same button the window came up and then slammed down inside the window. The plastic guides broke inside and had to replace. The following week, the rear driver side window did the same thing. Today, my wife got the car washed and the attendant was unable to get the passenger rear window up without using his hands to help pull it back up. I'm hoping I'm not having to replace that one soon. It looks like others have been having the same problem. I believe there should have been a recall on this part! we are on our way to palm springs and I hope this doesn't happen while we are on vacation!!!!

Window in front door and other doors jump off track and drop down. If hale storm, or heavy rain this could impair drivers ability to operate safely. Cadillac has many complaints due to this after I investigated it. I have 2 doors at present with windows broke. Please advise what I can do and expect GMC to do.

Power windows of Cadillac Deville spontaneously break, while driving, while sitting, in any types of weather. Cadillac is fully aware of the problem and refuses to fix. Many websites show other consumers with same complaints...such as www.cadillacforums.com. problem costs over $500 to fix and will break again (it is just a small plastic part). It is now at the point where people are posting "how to's" because it is such a persistent and costly problem. I have had to repair three so far.

All four window regulators went out within one year. The repair costs ranged from $487 to $587 each. I researched the parts but because everything is housed in one part for this model it was impossible to find something affordable. The labor was $75. Any number of consequences could occur from the distraction to the driver when the loud pop occurs, from what might enter through the window while driving, or from an accident that may require exiting the vehicle through a window. Only a fool would replace with an old part since these parts do not last that long and cost so much.

Right rear window emitted a loud "pop", and the window went down. Wedged the window in the up position as I was on my way to fla from New York. Upon my arrival in fla, took it to a dealer and they estimated the repair at $600. I refused the repair and dissembled the door and window assembly to find the cable that controls the window to be disconnected due to a flimsy plastic catch that had broken. After several hours I was able to repair the window cable with a metal piece. Clearly this is an engineering flaw( I was an automotive engineer for 20 yrs. Had cycle and age tests been done properly, this flaw would have been detected, but then, the dealers would be out $600 per window for a.05 cent part.

Three of the four power windows have broken in the past six months, at seperate times. Each time the window was being rolled down there was a loud pop and the window would not go back up. One I could understand, but three in six months on a $40,000 car is unreasonable.
