Faults:

Was trouble free till I blew a head gasket on a long climb, and then cooked the block. That was at about 125000 K's.

Replaced with another 3.9 with only 18000 K's. New one is a Vortec, and get fantastic mileage. On a recent trip to Seattle, I got 37 MPG all freeway. On the way home, in not so much hurry, I got 39mpg. (ltrs/100 mean nothing to me) Around town, we are getting 27mpg.

Brakes needed to be done at 75000 K's and at 125000K's. More because it was getting close than actually needing it. The "traction control" is crap. I shut it off whenever I drive it, or it will hammer away.

General Comments:

We inherited this car from Grandpa. My Father-in-law. He babied it, and took good care of it from new. It has been very trouble free.

Decent ride up front, but not too good in back seat. Suspension is soft and comfy, but has no road feel.

This car will cruise all day at 120 KPH, and get better mileage than your Honda or Toyota. It has been an excellent car for us and our 3 kids!! My daughter still calls it our gramppa car!!

Not sure why the head gasket went south, but that is what cooked (cracked) the block. The new motor though, is better than the last!! Better mileage, and about 25% more power.

Faults:

One ignition coil failed, due to to rust (my fault) at about 78,000 miles.

Leather driver seat torn.

Tires, battery worn out.

Rear window control module failed around 80,000 miles.

General Comments:

Aside from regular maintenance items such as the battery, plugs, and tires, nothing ever went wrong with this car. Even the intake was good when I sold it.

Everything worked very smooth. I would be hard pressed to list any problems because there just weren't any.

The only "glitch" about this car is that on a fast acceleration from a dead stop, the car shakes and acts the same way that a clutch does when someone isn't good at driving one. This car has an automatic trans.

I sold this car because finances are/were very tight. It was a hard choice.

The very few things I had to do to this car were spread out over time so it is not like it needed everything at once.

If you are considering one of these cars, keep in mind that Buicks are popular with the older crowd so a LeSabre has probably not been abused.

Faults:

Not many, the only one I can recall is the bolts holding the Power Steering Pump broke at about 158000 miles and it was very hard to steer. But it was an easy fix, but time consuming fix.

General Comments:

This car has a great engine and accelerates quickly and quietly.

The ride is very smooth and you can go over most bumps and not even feel them.

I would recommend this car to anybody looking for a great family car.

So far nothing has gone wrong with it. I got it last fall with only 9,400 miles on it, so needless to say it has been sitting for most of it's life. I changed most of the fluids as a precaution. I LOVE this car. On a recent trip to Yellowstone from Washington State it averaged about 29 mpg!!! WOW! I plan to drive it well into the 250,000 mile range! Can't wait to see how long I can make it last...
