2000 Buick Lesabre Fuel system Problems

the 2000 Buick Lesabre is a wonderful car basically a tank with the 3800 SERIES II you cant go wrong but the tiny little plastic part holding the throttle cable will dryrot even with a garage kept car under 150k miles please get them replaced I was driving and then the part came off and it got wrapped around the bracket and it took off I melted the breaks I wasn't stopping due to constant gas so I flipped in down into neutral to stop the vehicle from accelerating after i found a spot to pull it off the road but you can also put your foot under the peddle and pull up on it while pressing the breaks if you cant find a safe area while this is happening but i didnt relise it was happning until i hit 65 because the road i was on was a 55 and before i knew it i was going 90 luciky i live out in the rural areas

Incident

Sep 28, 2025

I started my car in the morning, per my usual routine. After a few seconds, I heard a very loud bang and the car stalled. A few seconds later, there was a large amount of smoke coming from under the hood. I opened the hood to see a large fire had started. My son, who heard the loud bang, came outside and saw the flames from under the hood. He ran into the house, grabbed a fire extinguisher, and attempted to put out the fire. He got the fire out but it was difficult. I had the car looked at by a mechanic and told me that the intake manifold had literally exploded. He has stated that he has never seen anything like this. It appears that the exploding manifold ruptured a fuel line. He told me there was a recall on this vehicle relating to a rupturing manifold and leaking fuel but that my vehicle had already had the recall performed. He thought that the new parts may be defective which is why I am reporting this incident.

The dealer was notified of the failure and advised the contact that they could not repair the vehicle under the recall because the VIN was not included in the recall.

THE FUEL GAUGE INDICATES PROPERLY UNTIL IT REACHES THE HALFWAY MARK. IT THEN FLUCTUATES AND IS NOT RELIABLE. THIS COULD LEAD TO RUNNING OUT OF FUEL IN TRAFFIC, IN-CLIMATE CONDITIONS OR IN ISOLATED AREAS WITHOUT INDICATION. THIS IS A SAFETY HAZARD THAT SEEMS TO BE PREVALENT ON THESE VEHICLES AND NEEDS TO BE ADDRESSED!

ENGINE SHUTS OFF WHILE DRIVING, SO FAR, ONLY AT LOWER SPEEDS. SOMETIMES, BY PUTTING IN NEUTRAL AND TURNING KEY, ENGINE STARTS AGAIN. OTHER TIMES, IT HAS TO SET FOR A WHILE. PUT NEW BATTERY IN 11/7/2013. PROBLEM PERSISTED. THREE AUTO REPAIR SHOPS, INCLUDING A BUICK DEALERSHIP, HAVE CHECKED IT OUT, BUT IT DOES NOT DIE ON THEM IN THE AMOUNT OF TIME ITS IN THEIR POSSESSION SO I WAS TOLD THERE WAS NOTHING THEY COULD DO. TYPICALLY, IT HAPPENS AFTER IT IS DRIVEN AT LEAST 20 MILES. CAME VERY CLOSE TO BEING REAR-ENDED AS I WAS UNABLE TO PULL OFF THE ROAD ENOUGH TO BE OUT OF THE WAY ON A ROAD WITH HILLS AND BLIND SPOTS. *TR

THE FUEL GAUGE DOES NOT READ CORRECTLY. IT WILL BOUNCE FROM 1/4 A TANK TO 1/2 A TANK TO FULL. IT IS ALWAYS ALL OVER THE PLACE. THIS IS A SIGN OF A BAD FUEL SENDING UNIT (ITS A SENSOR).

MARCH 30TH, 2007 CAR RAN ROUGH AND SERVICE ENGINE SOON LIGHT CAME ON. A BAD ODOR ALSO WAS PERMEATING INTO THE CAR WHILE GOING DOWN THE ROAD. CAR WENT BACK TO THE DEALER ON THE 31ST AND THEY HAD THE CAR UNTIL THE 3RD OF APRIL. I DROVE THE CAR ABOUT TWO MILES AND THE CAR DID EXACTLY WHAT IT WAS DOING BEFORE WHEN I DROPPED IT OFF. I DROPPED THE CAR BACK OFF THE NEXT DAY ON THE 4TH THEY HAD IT UNTIL SATURDAY THE 7TH. THEY SAID THEY CHANGED THE SPARK PLUGS AND THAT WAS WHAT WAS WRONG. I DROVE THE CAR AND EVERYTHING WAS FINE UNTIL FRIDAY THE 13TH. I WENT TO START THE CAR IN THE MORNING AND IT WOULDN'T START RIGHT AWAY. WHEN IT DID IT STUNK SO BAD FROM TO MUCH GAS FROM TRYING TO START IT. I RAN IT THAT DAY AND IT RAN ROUGH A FEW TIMES AND DIDN'T CALL THE DEALER. I LOANED MY CAR TO MY BROTHER FRIDAY NIGHT AND I DIDN'T TELL HIM ABOUT THE STARTING PROBLEM OR THE RUNNING ROUGHLY. HE WENT TO START THE CAR AFTER WORK ON SATURDAY MORNING AND IT WOULDN'T START RIGHT AWAY FOR HIM. HE GOT IT GOING AND HE TOLD ME THAT IT RAN ROUGH AND BUCKED AND JERKED. WHEN HE BROUGHT THE CAR BACK TO ME IT SAT IN MY DRIVEWAY FOR ABOUT FOUR HOURS. MY WIFE WENT TO START IT AND PUT IT INTO THE GARAGE FOR THE NIGHT AND SHE COULD NOT GET IT TO START SHE HAD TO COME AND GET ME TO GET IT GOING. I CALLED THE DEALER ON MONDAY THE 16TH AND THEY TOLD ME TO BRING IT IN THE NEXT DAY. I DID SO AND THEY SENT IT TO A GARAGE TO HAVE IT LOOKED AT. ABOUT 2:00 ON WEDNESDAY THE 18TH I STOPPED TO SEE IF IT WAS FIXED AND THEY SAID IT WAS THAT IT WAS THE SPARK PLUGS AGAIN THE GARAGE DIDN'T PUT PREMIUM PLUGS IN. THEY TOLD ME THAT THEY WASHED MY CAR FOR MY INCONVENIENCES. ALSO THE FUEL MILEAGE ON THE CAR WAS 20 MPG WHICH IS EXTREMELY LOW IT SHOULD GET 30-32 MPG. I TOLD THEM THIS ALSO. SO I GOT THE CAR BACK AND TODAY THE 19TH OF APRIL THE CAR IS HAVING PROBLEMS RUNNING PROPERLY. I RETURNED THE CAR AND THEY WONT CALL ME AT ALL. I FEARED MY CHILDREN'S SAFETY IN THIS CAR. *JB
