2001 Buick Lesabre limited. Left rear power window regulator failed to return window to a closed position. Temperature outside the vehicle was 99 degrees F. could not secure vehicle. This problem seems to be prevalent among this family of GM vehicles. Repair costs are exorbitant when the fault appears to be a small plastic bracket inside the window regulator. A simple repair kit is needed, rather than replacing the entire regulator. Vehicle has less than 60,000 miles on, and windows are not rolled down that often. Based on complaints I've seen on other web sites, I can expect to replace the other three regulators, with the cost approaching $2000 for all 4 regulator replacements.

Power windows on 2001 Buick Lesabre keep failing. I go to roll a window down, I hear a "crunching" noise, and the window will not either go back up, or it goes halfway up and stops. I have replaced 3 windows to date on a car that only has 28,000 miles on it. It costs 400-600 to replace each window. I searched the internet and there have been a lot of complaints about the windows in the Lesabre. GM needs to have a recall on this issue.

Power windows will not roll up and when pushed up continue to roll back down. This has been repaired several times. There is enough complaint about this defect that there should be a recall and the source of this problem should be solved instead of saying that it cannot be repaired to last. I think this is a disgrace and will not buy another GMC auto again. This should be reported to the government. Here is what they say: Buick power windows drop / broken power windows most Buick cars, and in fact most other GM cars, have this defect. The power window mechanism breaks - usually cheap plastic parts break in the power window pulley assembly. GM dealers will only replace the entire assembly, to the tune of $450 per window. Many, many Buick owners have written to say they have had to replace most or all four power windows assemblies, and some even had to replace the same power window assembly multiple times. GM has not changed the design of the replacement parts, so once fixed by the dealer, the problem still exists. The best way to deal with the power window failures is to get the power window assembly from a salvage yard. A lot of people get sick & tired of replacing these again & again, & tape up the window permanently. Currently there is no recall for the power windows, because it is not a safety issue (according to the NHTSA). So far, a class action lawsuit has not been filed. This could be a dangerous situation as my window has gone down when I am in the store etc. Someone could easily get in the car or steal something out of it. I think this is indeed a safety hazard. Also when going down the freeway and the window drops suddenly, it can be startling and could cause a wreck.

The passenger side rear window regulator malfunctioned. My daughter was in her child seat and it was pouring rain. I had to pull over, manually pull the window up and from there I had to get a new window regulator online and install it myself. I've read about numerous complaints with the Buick Lesabre (mine is 2001) window regulators and apparently there's never been a recall. I have the records from the previous owner and sure enough she had at least one fixed also.

I have a 2001 Buick lasabre that I have had to replace the window regulator in two windows and now the third window is broken. In July 2006 the passenger side front window quit working, and in April 2007 the right rear passenger window quit working. Each of these windows cost over $500 to repair. Now the rear driver side window is broken and I am assuming the driver side front window will break if I do not get rid of the car soon. I am going to get a new car, but you can bet it will not be a GM.

- Loveland, CO, USA

The right front window just failed to roll up. When I checked the internet I saw that the regulator on the windows of the Buick 2001 were defective so that there were many, many reports that the window regulators had to be replaced at approx. $400 per window. Buick refused to do anything about it.

Driver side window will not go down. I am assuming the motor is defective.

Like dozens of others reporting on carsurvey.org my 2001 (2000-2005) Buick le sabre power windows are defective. A plastic part breaks requiring replacement of the entire window regulator assembly including motor. Dealers charge $500 plus labor for each unit. I had a dealer replace the right rear window unit after the first time I used it. A loud crack upon activation and the window fell to the bottom of the door. Six months later I had to replace the left rear window unit. It took hours to remove and replace it with detailed instructions I found online (so many others had this problem one person documented what you need to know including diagrams). After market parts are available online also. So far they are holding up (2 years). Now my drivers door window has snapped but it did so while raising it the few inches it was open so it is closed and staying up for now. That makes three of the four windows. I'm sure the front passenger side will fail as well. GM should have recalled 2999-2005 Buick for these defective windows. You can easily find dozens of similar reported cases online. Otherwise this is a fine, economical, reliable car. Too bad the windows ruin the experience.

- Fernandina Beach, FL, USA

Both rear windows failed to go up. One window broke last spring and the other broke shortly thereafter. We inquired from a local dealer the cost to have the regulators repaired and were told the price would be approx. $400 per window therefore we have not had them repaired. The front passenger window has recently begun to hesitate when operating it so we chose not to use the window fearing it would also become stuck in the down position. As of March 27 I began performing searches on the internet for similar complaints and learned this is a known and common problem with the 2001 Buick Lesabre. Therefore I feel a recall should be issued and GM should replace the regulators free of charge.

My left rear window in my 2001 Buick Lesabre made a loud noise and then slid down and will no longer raise up. Because I cannot keep the window up, this has become distracting and has led to water getting in the car in bad weather, which could lead to mold and health problems.

Noticed driver side rear window was down on Thursday 11/1/07. Tried to close it, but control didn't work and window kept sliding down into the door. Was able to pull up and tape shut until repair. On Sunday 11/4/07 the rear passenger window was down and wouldn't go up. The rear windows are never lowered. Local mechanic was able to repair at a cost of $443 for both windows. Dealer was going to charge around $500 a window. After seeing hundreds of complaints of these plastic regulators failing, GM should be forced to recall or reimburse owners for this repeated failure that seems to have existed for several years.
