I've owned this Liberty less than 3 years. Since then 3 windows have stopped working: left rear window 2xs; left front window 1x. The left front is starting to go out again. When the vehicle was under warranty, Chrysler fixed the first 2 broken windows. I'm a high mileage driver: 25,000 miles/year. The vehicle is out of warranty DUE TO MILES and Chrysler will not cover fixing the third window. I would understand if the window had something to do with miles and it wore out. It's obviously a defective part & Chrysler won't stand behind their parts. Be prepared to pay appx. $450 to get the window fixed out of warranty. On a good note, the engine is great at 64,000 miles. No problems there.
