Since I bought the Buick Lesabre in 2002 all 4 windows have had defective motors in them. I feel this is a manufactures defect and they should reimburse me for all the time and money it has cost me to have these windows fixed. They have all failed with in a years time during the summer months. I have had to take the vehicle in on 4 separate occasions because they would not fix the motor unless they actually saw it when the motor was stuck and not working. I live over 50 miles away from the dealer and I had to rush over there so they could see the windows when they wouldn t operate. I had 3 of the 4 window motors replaced but they refused to fix the last window because it wasn t sticking at the time I brought it in. Now the 4th window is broken and it will not go up or down yet my warranty has run out. I paid 100.00 every time they took my vehicle in for repair. …
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)". …
Driver's window regulator inoperable. Rear window on same side same thing, but repaired in late 2004 - bought used but rear windows not used by me at all. Driver window used often, but this would be the second $500+ bill to have it repaired. It seems there has been a known problem for quite some time, but I have not found anything that says it has been addressed. Car now has over 100K miles and I'm having a hard time justifying the expenditure. Also entire dashboard cover 'lifting' up more than six inches. Told by a repair shop that the only way to fix it is to take out the front windshield - another $500 to shell out. Also has noise of metal rubbing coming from rear, but cause cannot be pinpointed. Sounds like a large piece of something. …
What a pita this 2000 Lesabre has been. I will never purchase another Buick. (the least impactive of the five window failures); on a local freeway, I touched the right passenger switch and the window dropped open. Even though it was during winter months, I was able to make it home, open the door panel and wedge the window closed (duct tape). I cannot remember the details of all of the failures, but I am very fortunate that my wife was not driving in a bad neighborhood when any of them happened. The first couple of them occurred during the warranty. I asked to talk to the zone person after the 2nd occurrence. No joy with that experience. I was totally ignored. Thank god I have mechanical abilities (dad). I discovered that I could purchase for a whole hell of a lot less off of the internet a new/refurb unit rather than paying the extortionist rates of the garage. …

Since purchased new, a 2000 Buick Lesabre has had all four power window regulator assemblies fail without warning, I.e., the windows stopped working,(not all at one time, but over the intervening years) creating a safety problem in the event of a need to evacuate the car, to conduct business at a toll lane, for example, or to respond to a police traffic stop. And the driver's window has failed a second time, after having been repaired by Buick, for a total of five failures of the same electrical/mechanical system. Buick replaced the first assembly under warranty. The next three repairs cost approximately $435 each at Buick. The fifth repair was done at an independent repair facility at a cost of $333. The independent shop and several other sources have anecdotally related many other incidents of an obviously defective electrical/mechanical system. …
Buick Lesabre 2000 window regulator failure on the rear driverside passenger window. Car has 60,000 miles on it. Driving car and went to put up rear window and it made a strange grinding noise. Window would not roll up. Luckily the failure did not occur at high speed or adverse weather conditions. Upon research of problem it is apparent that this model vehicle has constant failures due to poorly made plastic parts. Consumers have reported multiple failures, some during inclement weather. NHTSA and GM refuse to do anything about the issue. Buick refused to even acknowledge the issue. A search on google for 2000 Lesabre window comes up with over 97,000 results, most of them coming from automotive forums with people having repeated issues with this feature. The dealerships charge customers $300 to $500 each time a failure occurs. This issue needs to be addressed through a recall. …
My 2000 Buick Lesabre custom sedan. The drivers and right rear windows suddenly drop open fully without warning due to failure of electric motor of each window cannot power them back up because of a failure of the lift mechanism. This repair costs 400.00 per window and is a known common failure of the 2000 to 2005 models. Recently occurred to driver;s window on May 7, during a rainstorm and had to pull over and stop; luckily on low traffic street at time. Rear window drop occurs more often and each time, I stop and with both hands raise the window and place paper shims to hold the window up. This presents a dangerous situation if it occurs on a busy highway/street as the driver suddenly loses focus temporarily. And is placed in a dangerous position as it is known that crashes occur in mere seconds during highway speeds when drivers take their attention away from driving. …
