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.

Buick LeSabre Problems
Engine Stalling Due to Mass Air Flow/Crankshaft Position Sensor Failure

Verified
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.

CAR IS IN EXCELLENT CONDITION WTTH 85000 ACTUAL MILES
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!!
when I turn my car off and take out the key , open the door and the warning sound is letting me know my lights are still on. the brake lights and parking lights will not turn off. all other lights go out but not the parking lights or brake lights. does anyone have any suggestions?
