I have a a little over 44,000 miles on my 2006 Jeep Liberty Sport and I have had to have the regulators in the windows replaced five times. Three times for back passenger windows and twice for the left driver's side window. The motor crunches and then the window just disappears into the door. I picked up my vehicle from being repaired for the fifth time yesterday and am afraid of letting the windows down for fear they won't go back up. I wouldn't recommend this vehicle to anyone.
