Our Buick had been running fine, but went to move it one morning. With a cold engine, as soon as we hit the starter, the engine exploded very loudly and started burning. After the fire was put out, it was determined that the entire intake manifold, along with the fuel lines had exploded in many pieces. From internet research, it was found that the fuel pressure regulator had a recall for vehicle years '98-'00, which these models had the same condition. Had I had the hood open at the time, I'd probably been hurt by flying chunks from the intake manifold. This is a very dangerous condition which could have easily caused bodily harm, even from fire to the passengers inside.
Engine of my 2001 Buick le sabre, v6, 3800 engine, caught fire after an oil change and short drive home. Authorized mechanic diagnosed it as engine oil leaked out of gasket and on top of exhaust manifold, triggering a fire that quickly melted the plastic wire harness cover and started burning through the wires. I caught the fire early as it was in my driveway and I had a fire extinguisher but fire was spreading quickly. I am unable to afford the repairs.
The contact owns a 2001 Buick Lesabre. The contact stated that while driving at approximately 45 mph, there was smoke coming from under the hood of the vehicle. The failure recurred numerous times. The vehicle was taken to an independent mechanic where it was diagnosed that the manifold failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 93,000.
In December 2010 I had my 2001 Buick Lesabre repaired at schepel Buick in merrillville, indiana. They replaced the intake manifold gaskets and the thermostat because of the coolant leaking. I just found out the gm knew of this problem with the dex coolant for a long time and didn't let anyone know. I called the service manager a schepel bill and talked to him and he said that he never heard of this and neither did gm. Its all over the internet. He lied to me. He told me not to believe what the internet says. I am out $779. 45 for something that they should have paid for. The never had a recall because they wanted to keep it quite. I just don't think that they should get away with keeping it quite when someone could get hurt and to avoid paying for their mistake.
Vehicle stalled intermittently while driving. Vehicle was towed to an independent shop, and mechanic indicated determined that intake manifold was cracked and caused coolant to leaksinside the engine.
Leaks coolant. Dealer said it needed an intake valve rebuild kit, approx. $600.
The rear rotors were hanging up, make noise, pulsate, and the front end of the vehicle vibrates. The consumer states that the front end vibrates, the door assembly is misaligned, sticks out, and noisy, the tire was changed but failed balance and theres a vibration, the engine stumbles/stalls, the interior cloth by the top of the windshield is loose-3 times, can hear a moan coming from the windshield, the onstar antenna fell apart, the torsion rod vibrates, the steering shudders at slow speeds and on turns and the hose/bulletin # 99-02-32-007a, power steering, and hydraulics have been replaced-8 times, the a/c blows hot air/bulletin #990139-004a, and the vehicle pops/bangs when going over bumps and making turns, theres a rattle noise from under vehicle/possible exhaust or air pump-cause: intermediate exhaust pipe rattling (internal) front exhaust manifold to oxidation catalytic converter-replaced, wheel alignment (pulls to the left), there was a rattle noise from the left side of the pillar molding/removed the a-pillar trim and insulated/align/against upper dash, and getting poor fuel economy/idle air control-reppaced.
Technician indicated the original antifreeze which gm used in the Buick Lesabre damaged the intake manifold and the head gasket. Both needed to be replaced. Fumes from the toxic antifreeze caused the consumer to experience nauseousness and dizziness. Dealer notified.
