It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

2001 Buick LeSabre Problems
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

2001 Buick LeSabre Reviews
My 2001 lesbre has been one of the best car I've bought in a while the only problem I've had since day one was the fuel gauge bounce from empty to full which I took care of by replacing the fuel sender I bought from eBay for 27 dollars and it took me about 20 minutes to replace other than that I have no complaints
I bought my 2001 Buick Lesabre car at a small car dealership, one I've bought from before,here in my town. The check engine service soon came on and stayed on right after I bought it. So I took it back to the dealership to ask why and he checked it with his checker thingy and the light doesnt come on anymore but now the speedometer isn't working right, and it was before he checked the engine service light. The speedometer reads at least 30 miles over the actual speed I'm going. I was told it could cost me $200-300 to have it fixed at the dealership. Otherwise the car runs smooth and everything else seems to be working good.
Same here, gas gauge bounces to say Full when reaches about 1/2 full, driver side heated seat - not working; dash buckled - I glued it back down and put a dash pad on top. But I love it! Got it used on Ebay for $4500, 2001 Limited, 58,000 miles. Runs great, no rust, minor scratches. Will definitely keep it!!
I have read some of the blogs and I can tell u this.u guys can save a lot of money by more research.like the gas gage going to full to empty. Here's the thinf a new fuel pump off eBay and one hour anyone can do it..I fixed mine for 50.00 and .now it's not for everyone but most problems.can be fixed if u just look up the issue
I bought my 2001 Buick Lesabre from a dealership in Boynton Beach,fl with one prior owner and 60,000 miles on it. I have had problems recently with the watrer pump seeming to leek xoolant from somewhere, replaced water pump and still loosing coolant. I was told by Pep Boys to use dex cool on my last oil change and since then I have had a jerking in my engine at start. i read a bit on dexcool causing these problems. Go to Consumeraffairs.com and it will show you all compaints on this product. Also always replacing my power window mechanisms, always breaking and very expensive!!! I also hear a grinding noise in my front wheel hub and it was diagnosed yesterday as a rusted front hub assembly. They told me i should replace both sides at $200 each! My gas gauge isnt working, it jumps up and down and i always have to fill it when it starts to bob. Estimate for that a whole new fuel pump and sensor attached (cost $700) I love my Buick but I am dissapointed if this Dexcool product is sabotaging my car :(
