Alternator/generator/regulator problems of the 2000 Buick Lesabre

The contact owns a 2000 Buick Lesabre. While driving 50 mph, the engine lost power during acceleration and the battery and security warning lights illuminated.

The approximate failure mileage was 180,000. The VIN was not available.

I have replaced all 4 window regulators twice. I have done research, and it appears many have the same issue. Buick claims to sell "luxury" this is far from luxury and is unsafe! driving 65mph and the windows just go down. . . . Then won't go back up! my car had to sit outside with both back windows down!.

The driver's side window intermittantly stopped working and the motor was replaced while the vehicle was still under warranty. Now the rear right side passenger window stopped working one day after it had been rolled down. It was looked at by the Buick dealer, and I was told it would cost well over $500. 00 to fix the window regulator and motor. I asked them at the time if there was a recall on the window motors, since I had already had to have one motor replaced, I was told no. I have since had to pull the window up manually, and tape it so it does not fall down. (not a pretty site). I feel this is a problem and am afraid it will happen to another window and will be forced also to fix that one at a hefty price. I believe there should be a recall on the window motor mechanisms.

Failures: replace faulty general tires. Replace fuel pump 26000 miles. Eplace intake mainifold, eplace coil and spark plug wires at 52000 miles. Replace window regulators (4x's), replace transmission 63000 miles. Replace wheel bearing 74000 mi driven gently by a little school teacher - what a hunk of junk.

The dash board buckled. Passenger window regulator broke drivers window regulator broke rear passenger window regulator broke rear drivers side window regulator broke passenger window regulator broke-again light button stuck on.

When left passenger side power window was let down consumer heard a cracking noise. The plastic window regulator broke. Dealership replaced the part. Also, dealer informed consumer that this was a common problem with this part, but they were still replacing it with the same part. The same defect also occurred on the right passenger's window. The outside temp sensor failed and as a result the indicator read the incorrect temperature.

At the first filling of gas tank, fuel came out of bad gasket and spilled fuel causing wicked bad fuel smell through out interior of car. Heater has never operated properly. The only way that you can be comfortable in cold weather is to operate manually. The alternator has always had a very noticeable and annoying hum at slow speeds. The alternator has been replaced twice, with no improvements in the noises. Power assist failed and as a result I lost all braking and a strong odor developed inside the car. This is ok now and along with the gas tank is the only things that have been repaired.
