Best advice, stay away from Buick.

We had the same car in 1989 with wonderful reliability.

This car was the opposite of that car.

Not all newer Buicks are unreliable, in fact I would venture to say most are not. The 2000 LeSabre was a brand new model, and it does seem to have a lot of issues; some of which GM corrected by the end of the model run.

My last 4 cars have been Buicks, and all have served me very well.

Also to be fair, when Buick introduced the '86 FWD LeSabre, reliability was fair at best. By 1989, Buick was winning awards at Flint for reliability and Buick was the most reliable American brand into the early 90s. It takes time in many cases to work out the bugs in new models. When you buy the first model run of a new design, you always take a risk of experiencing higher problem rates than with a proven design.

Let's see.. here is the list:

Regulator on back window has now gone out twice.

Ignition coils have all been replaced, ignition module failure.

Fuel injector replaced once, then a new clean out had to be performed due to the rough running engine.

Coolant leaks.

Back oil seal leak.

Front brakes warped, back brakes warped.

General Comments:

Overall not impressed with this car at ALL. Biggest POS I have ever owned. Mostly due to GM not standing behind their products. Most issues are known, and GM refuses to take care of them. If this car was made by Toyota, all these issues would have been taken care of years ago.

Love the car when it works, but would NEVER recommend this thing to anyone.

Oh, and yes I know that this year was a new model design, but this car was made on well known platforms, and using an engine and transmission already in GM's line up for years. These issues going wrong should have never happened, regardless of the model redesign. Booo on GM. Making lousy cars with lousy parts so their dealerships can make money off the backs of the consumers. Never again.

I work for Toyota manufacturing; they only fix things when a dealer does it. Corporate doesn't care so long as you keep buying overpriced cars.

I love my car, very economical and comfortable


My car shifts hard after warming up. I was told to change the sensors inside of the transmission cover. There are a few sensors that are not cheap. It costs over $500.00 for the garage to replace the sensors.

I have been driving for a while with this problem. I first used Sea-Foam in my transmission fluid, and it helped for a week, but need to change them now. It will eventually take its toll on my transmission if I don't change them soon.

I'm not an expert, just a typical house wife and mom that likes to work on her own car.

Ask your mechanic about this. I think it will help. Be Happy and Healthy.

Good for you that you work on your own car. I am impressed.

Don't try changing sensors or anything else inside the transmission. I doubt that you're familiar with the inner workings of a modern automatic trans. Have someone who knows what they're doing replace the sensors, if you haven't already done so.

As far as an additive for trans fluid, put in Lucas trans oil additive; it's the best stuff out there to use.
