2004 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.

2004 Buick LeSabre Reviews

CAR IS IN EXCELLENT CONDITION WTTH 85000 ACTUAL MILES

it's a wonderful car. I bought it used in 2000, and have had absolutely no big problems. It has 96,000 miles on it now. one thing, I had to have my heat sensor replaced twice, and it was not even that. after I wised up and put my buick gas cap back on it instead of the locked gas cap I bought at walmart, it has never had that problem again. it was confusing the computer, I think. the light turned off immediately upon putting the original cap back on. then I had to replace a right front brake pad. and then too, the top came off the console. I have that just laying there where it belongs though and no one is the wiser... I think this car is great for a senior woman as myself. I have taken several long trips. never any problems. Thank you GM and thank you Lord!

What a great car! Over 8 years old and 170,000 miles and still going strong. It's taken us on numerous long distance family vacations safely, smoothly and reliably. Minimal repairs. Love that 3800 Series II engine; I sure wish they still made it today. Today's cars can't touch its power or fuel economy!

I LOVE THE AIR CONDITIONING & HEATING AND I LOVE THE ENGINE I LOVE EVERYTHING. YOU DID A VERY GOOD CAR

I bought this car as a used company fleet car in 2005. I always get over 26 MPG in city driving, better than any of my friends! Remember Savannah is on the Atlantic Ocean, so it is very flat terrain here. I am fanatic about the oil changes & tire rotation. Quiet and comfortable ride! My third Buick. Only little things have gone wrong, like the backseat cup holder fell off & I just now replaced the brake pads. Good car & carries 6 passengers comfortably. Wish it had a "pass through" from the backseat to the trunk however. What's a drive train?
