We are about to replace our third electric window. The first failed during the warranty, and was without charge. But now, the dealer is charging about $500 per window. The windows just made a grinding noise, and then refuse to move. The first time, the window just fell suddenly... kind of scary. We seldom use the windows, so over-use is not the problem. We have never had this problem with 4 previous Le Sabres.
Generally the car is great. Very comfortable and reliable. Only the windows are faulty.
I also have a 2002 Buick LeSabre, and I am now replacing my 3rd window (power regulator). First one was under warranty and the 2nd one was 484.00 and will now pay that again for the 3rd window, only a matter of time and will probably be replacing the 4th one. It is a shame that Buick lets a flaw like this persist and should have been under a recall for faulty parts.
I have a 2002 Le Sabre with 71,000 miles. Three of the windows have failed - one under warranty (28 K) and two within the last 13 months (58 K and 71 K). The last two occurred during trips and involved the rarely used rear windows. The dealer offered to split the $600.00 charge/window, but not w/o much complaint. They charge for a diagnosis, $53.00. They claim that they see only a few such failures per year. I contacted the Customer Assistance Center recently as directed in the Users Manual to resolve this manufacturing or design issue, but they merely referred me back to the dealer (based on my experience, they offer neither assistance nor satisfaction to the customer).
I have no confidence that the repaired power windows will perform long-term in my present car and am concerned that the fourth will go soon. The cost of consistently repairing the windows could approach that of rebuilding the transmission, not to mention the aggravation and uncertainty of failures. I am debating either trading it in for something else or getting rid of it. I will not purchase a Buick or GM car based on this continuing problem and lack of customer service. I have owned five GM cars in the last 20 years, however this was my first with power windows.
