I own a 2000 Buick Lesabre and in the last 9 months three of the four windows have stopped working. The only window that hasn't failed yet is the driver's.

Rear window motors or mechanisms replaced 3 times a piece, front right 2 times, front left once, drivers side only one that works now.

A total of three power windows have failed on this vehicle, all by lowering the window, then failing to close. Repair bill on first two was refunded by GMC, evidently because the mileage was less than 60,000. Third window failed on 8/13/08, mileage 76,000. GMC declined request for assistance on this expense, $596.69, because of "age of vehicle and mileage". from research on the internet, I understand the cause of these failures, mine and others, is a plastic pulley which breaks. The complete window regulator pkg. Is then replaced by the dealer, since they don't or can't replace just one piece of the mechanism. I can understand how this defect could cause an accident, due to the shock factor, by a window dropping open suddenly by itself at highway speeds.

I have a 2000 Buick Lesabre with faulty power window motor. This will be the 2nd replacement for the passenger side window. Based on other website chat rooms this is not uncommon for this vehicle. Buick needs to recall the motor so that this can be fixed. My vehicle only has 42,000 miles on it and its in great condition however, as a safety issue the windows must be operational and function correctly.

I have a 2000 Buick Lesabre limited that has constant failures in the power window system. I have personally replaced all 4 mechanisms due to windows that either drop down unexpectedly or fail to roll up or down. I continue to suffer from the same problem even with the new mechanisms. This has caused among other things, water damage to the interior of the car as the window would not close.

Window regulators fail in the power window mechanism. It has occurred in all four windows over the past year and a half. I had the driver's window repaired, the other 3 are non-functional. One of them (rear driver-side) is stuck in a position that is 1/4" from closed. The dealer service department told me that was the best they could do (besides duct taping it closed!). the repair costs $450 - $500 per window, which is ridiculously out of my budget.

The contact owns a 2000 Buick Lesabre. While stopped, the rear driver side window fell offtrack and the contact had to manually pull the window up. On the second occasion, the rear passenger side window fell offtrack when she drove over a railroad track. On the most recent failure, the contact cracked the passenger side window to get some air and the window did not go up. The door panel had to be removed in order to get the window back up. The dealer stated that they were aware of the defect and there have been other complaints. They issued tsb number 3483 regarding the same defect. The manufacturer stated that they would investigate the issue, and later stated that due to the age of the vehicle, they would not offer any free repairs. The cost of the repair is $500 per window for three windows. The failure mileage was 48,000 and current mileage was 51,000. Updated 09/17/08. Updated 09/25/08.

The back window of my 2000 Buick Lesabre stopped working...couple weeks later the other back window stopped working. I then did research on the internet and many many individuals had the same problem. One month later the passenger window stopped working and a month after that the driver side stopped working. All of the faulty windows stopped working this year 2008. How can they all fail at the same time. To repair each window costs around $500 each or a total of $2000...10% of the original cost of the Lesabre. From your web site " Federal Motor Vehicle Safety Standards set minimum performance requirements for those parts of the vehicle that most affect its safe operation (brakes, tires, lighting) or that protect drivers and passengers from death or serious injury in the event of a crash (air bags, safety belts, child restraints, energy absorbing steering columns, motorcycle helmets)". now if one needs to escape from the auto, especially a child, do to failure of the door opening the windows have now created a safety problem. Once again there have been many many individuals with this problem...many that have not submitted a complaint...even the auto technicians indicate this has accrued more then it should. Finally, I believe the faulty power windows are a safety problem and Buick should take responsibility for this faulty equipment.

Buick Lesabre custom (2000). The driver's side rear window stopped working. Mechanic said it is the window regulator. Part cost about $250. Assembly includes motor. Found out that this is a common and widespread problem with that this car. The years 2000 to 2005 on these models all have the same type of assembly. Found out a lot of others have the same problems at www.carsurvey.org/viewmorecomments_review_38504_2.html there are no doubt many others we haven't heard about that have the same problem.

All four of the power window regulators failed. The cable on all four parts became worn and broken. The windows did not function properly afterwards. New parts were purchased and installed, but the replacement parts are identical to the ones that failed.

Buick Lesabre cars all have faulty window regulators and they break soon after the warranty is out and the cost to repair is out of site, after you replace one the next window breaks and then the next, Buick needs to do a recall on these and fix everyone that breaks, the regulators are cheap made.

Continuing failure of power windows regulators in 2000 Buick Lesabre. I have replaced four regulators since purchasing a 2000 Buick Lesabre in 2003. The design of the parts is faulty and they can fail at any time. When a window suddenly drops down in traffic, the resulting distraction is a safety issue. This is shoddy design and irresponsible manufacture and design.

Without warning the back passenger window on 2000 Buick Lesabre has stuck about 4" open. After researching on-line there are numerous postings of the same problem detailing the plastic part that moves the window fails and a stamped 'void' at the breaking point of the plastic. These postings list multiple failures in the same car and differing ages of the parts including during warranty and after. I expect to pay $400 for the replacement of the defective part. Please research.

The power window on the rear passenger door popped and quit working. This is the second window that has failed and the car has 85,000 miles. The first failure happened under warranty. I use the rear windows very rarely because I am single and my child has his own car. There are just two of us and I use the window for ventilation once in a while. A third window is giving me problems with occasionally working or not so I am sure it will be the next to go. I have read extensive problems listed on the internet with this very some issue. Buick should not depend on plastic and a part with a poor history - they are above that!

Bought a 2000 Buick Lesabre as a student vehicle. Within two months the driver side window mechanism failed. Fixed the driver's side window mechanism at a cost of about $500. Subsequently all three other windows failed.

The contact owns a 2000 Buick Lesabre. In October of 2005, the front driver side window dropped and would not roll back up. The contact took the vehicle to the dealer and was informed that a plastic cuplin failed. The vehicle was repaired by her son. The contact wrote a complaint letter to the manufacturer and never received a response. In August of 2007, the windows began to make a grinding sound when they were opened or close. The failure occurred with all four windows, but was worse with the two rear windows. She called GM and was informed that they would investigate the failure, but they never called her back. Months later, GM called and stated that nothing could be done. The failure mileage was 98,565 and current mileage was 147,000.

2000 Buick Lesabre custom purchased new with less than 28,000 miles both front windows (electric) will not operate. I have read hundreds of comments on the internet regarding this problem. People driving down road & windows fall down. It is not safe to have windows that will not operate. Cost to repair is $400 plus per window. Buick should do a recall.

Power windows dropped into the door well. Both a rear passenger and drivers window unexpectedly fell into the door well, and would not roll up. The rear window dropped in November, the driver's window in January 2008. Its cold in Michigan in January, I was unable to drive home.
