Buick has not had enough contacts concerning the window regulator defect. Anyway, that is what the representative I spoke with told me. I have started a group on Google for Buick LeSabre owners to account for their problems. With this information, owners can contact Buick with more than my car has multiple window regulators broken. There are many of us out there that obviously have not contacted Buick directly concerning this problem. I urge all Buick LeSabre owners with regulator problems to visit my group at Buick LeSabre window regulator and then Buick.com, and email them concerning your cars problems. Buick will get in touch with you concerning your problem. With enough contacts, Buick will have to realize there is a defect in the regulator. In fact if you research the Internet, there are companies advertising modified Buick LeSabre window regulators that have fixed the plastic part defects made by GM. If you have had repairs made at GM, be wary of the regulator, because it has the same inherent defect as the original.

I bought a used 2002 Buick Le sabre in January with 50,000 miles. It now has 62,000 miles and I am on my first passenger side front window regulator at a cost of $529 including a $50 coupon for repairs over $500. I wonder if the previous owner replaced the other three. No more Buicks for me. I had a 1997 Le sabre with 150,000 miles and no window regulator replacements.

I also have a 2002 Buick Lasabre with a problem on the passenger side front window. It quit working in the up position. I was checking this site to see if others had experienced similar problems. I was shocked at the volume of problems with the windows. I purchased the vehicle new and have not had any problems until this occurred. It sounds like I need to get prepared for more of the same.

Buick better get ready_ I may not win, but I will worry the very life out of them until they will probably wish I would go away.

Let me add to the litany of horrors. I just purchased a used 2001 LeSabre, and lo and behold neither of the back two windows worked. I did not notice this "slight" inconvenience until my son tried to lower the left side and it went down, about half way, and stayed there. That happened shortly before I found out the passenger side window wasn't working either. Then, in checking, I found that the rear controllers were unplugged most likely to keep passengers from rolling down the windows. That's when I went to the internet, googled the car make and model and window problem and found all these wonderful comments.

Now I don't know what to say. Maybe just, thanks Buick! is enough?

I have owned 2001 Buick Le Saber from New. I currently have the word "ERROR" on the drivers info center under the odometer. can't find any recalls or corrections in the users manual. anyone have this problem? I had the drivers side window repaired about a year ago. stuck down. Happy with the car and looking at the Luzerne. Paul

I bought a new 2001 Buick Le Sabre and vow to never purchase one again. I have replaced five window regulators (the right front one just went for the second time) at over $400.00 each. There is definitely a problem with the design and Buick should be made accountable. It is not fair. I am going to write to Buick and complain loudly as all of you others with these lemons should! If enough of us complain maybe something will be done.

To 15:33, you might try disconnecting your battery and re-connecting it. I have heard of this correcting a similar problem.

Let me add my familiar story. 2001 Buick Lesabre, car has 60,000 miles and 4 broken regulators in the last one and a half years!! 1700.00 later...

We have replaced all 4 window regulators on our 2001 Buick Le Sabre Custom now. The first one costing just under $400.00 at the local dealership. Last 3 were purchased on line from 1Aauto costing about 100.00 each. Labor to replace each regulator was about $80.00. Now we are having problems with the intake manifold leaking coolant. Would cost about $1500.00 to fix from a dealership. I can buy parts for about $400.00 and labor will cost about $300.00. We have the V6 3800 series II engine. Whats next to fix?

The leaking coolant at the intake manifold is a recall on 3.8L LeSabres. I actually had Buick contact me and adamantly insist that I bring my '02 LeSabre in to have it checked/repaired.

As for the window regulators, I've got 73K on mine and the right front window regulator just went. Ran the window down, and it refused to go back up. I took the door panel off and manually raised the window (rain was in the forecast) and got on here to see if I could get some info on it. :- (I'm pretty handy... I'll probably end up pulling the whole mess out and seeing if I can't find a way to fix it so it'll stay fixed... I found an article from a Mitsubishi owner that described a similar problem. It had to do with a plastic part holding the upper pulley in place. He fabricated a metal one to solve the problem.

I don't quite understand the concept of giving the entire vehicle a bad rating because of one relatively minor shortcoming.

Sure, I'm not happy that my Le Sabre has flimsy window regulators. On the other hand, I can't think of a single other large sedan that comes anywhere close to the Le Sabre's reliability.

In 73,000 miles this is the first problem I've had with the car. The Buick 3.8L V6 is arguably the best American-made engine ever built from a reliability and durability perspective. Change the timing chain at 150K-175K miles and keep clean oil in it, and it'll easily run 250K miles before any sort of major repairs, and it'll get 30MPG on the highway. I've had Honda Civics that couldn't top my Le Sabre in fuel economy.

If you need a big sedan with a big trunk, there's really not much of a contest. You could go out and pay $50K+ for a big Mercedes sedan and end up with a vehicle that tops the list for unreliability. You could buy one of the larger Ford products... enough said there. (for 2006, Lincoln and Mercedes rated as the two most trouble-prone cars on the road). I've been there and done that, and my Buick is a real gem next to that garbage.

So, am I thrilled that my window just broke? No, but if you shop around you can get a new regulator/motor assembly online for $79, and if you're reasonably handy you can install it yourself in an hour or so. That's not so terrible in my book considering I had to unload my last Ford at 63,000 miles because it was costing me an average of $400 per month in repairs.
