2000 Buick LeSabre Problems

Electrical & Lights -- Verified

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.

Engine -- 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.

Engine -- Verified

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.

Heating & Air Conditioning -- Verified

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.

Drive Train -- Verified

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.

2000 Buick LeSabre Reviews

the 2000 buick lesabra limited is by far the best car i have ever owned!28mpg, sure i had a few maintance issues but expected it now has over 300,000 miles and yes that is the original engine and tranny, i have changed oil every 3000 miles, and i adapted to the fuel gage sticking on full all the time 3 water pumps isn't that bad when you consider there's 300,000 miles on the car. i am sorry to see that generation of luxury go.

Repairing the stabilizer system in my 2000 Buick La Sabre. Would like as much help as I can get. Never done it before and not a mechanic.

when I first got this car I was super impressed. Heard great things about the engine. Bought it used at 48k. Had it checked and rechecked by mechanic, nearly new condition. Fast forward.... Inner and outter tie rods replaced, window regulator/motors replaced twice, 2 Ignition Coils, Leak from Manifold area, Brakes needing replacement more often than any other car I have ever owned, eats through rotors, compressor for the suspension system failed at 50k, power steering pump failure, rack and pinion replacement, security system keeps malfunctioning, etc.

The engine itself is great, its everything else that keeps failing.

The 2001 Buick LeSabre has been great on gas and has been our most reliable vehicle since my 1995 Olds Cutlass convertible with 250000 mile when it finally needed more work than a newer vehicle would cost. 2001 Cadillac Eldorado was junk and the 2003 Ford Exploder (not sp) was even worse. The window regulators on the Buick are as one person wrote a joke. You could by a box and replace one a month and never stop. The gas mileage and ride are superb and we have had no engine problems except Air Conditioner. The seat at 160000 miles is starting to get low (could be mice but, that is my own issue. They built nests in the heating ducts and got in through the passenger cabin filter housing.) We are on our second battery since 2005 and would have bought a new Buick except the new ones get worse ratings than the old ones.

I have a 2000 Buick Lesabre Limited that had been my fathers. This car has only 41000 miles on it as dad did not drive it much. He bought it new from dealer, always garaged, always serviced per owners manual at dealer. It can be a good car when running properly, but this car's durability is worst of any car I have owned. Transmission had to be replaced at only 31000 miles, by far lowest miles of any brand vehicle I have ever owned, and GM and dealer were no help. Apparently the left rear window regulators tend to fail even though they are not used much - have seen this on friends cars. I had a 10 wk period last year when car had to be repaired 4x, mileage only 30-35000 at time. front seat heater failed shortly after I began driving car, about 23000 miles, dealer says over $400 to fix. Would not buy a Buick based on this experience.
