The contact owns a 2000 Buick Lesabre. While the vehicle was parked, the contact noticed a burning odor and smoke. After the hood was opened, the contact noticed leaking on the exhaust manifold. The vehicle was not diagnosed, but the contact replaced the gasket. The manufacturer stated that due to the vehicle not being manufactured at the same plant as the defective vehicles, the VIN was not included in NHTSA campaign number: 15V701000 (engine and engine cooling). The failure mileage was approximately 137,000. Updated 08/31/17

Leaking oil onto exhaust manifold causing burning smell and smoke which permeates passenger compartment. This car has the 3.8 series ll engine which has a recall for this problem on the regal but not the Lesabre. This is definitely a problem on the Lesabre too. Why is it not included in the recall? often happens while driving but the last time was when I had just pulled into my driveway and smoke poured out from the hood. Using the recirculating air setting seems to help smoke from entering the cabin. Why is this not included in the factory recall!!

As I was driving my Buick Lesabre 2000 my windows lock up on me it was a very hot summer so the electrical windows with no go up and down. The engine is bad. 1490000 miles. Electrical system is problems. The car wiring is loose and can be a dangerous. I tried to pull window down and repair its manually frozen with no power. My seat are uncomfortable with hard iron wire.

While driving the vehicle at 35 mph, the dashboard check engine light illuminated. The engine idle speed became erratic and the vehicle stalled. Upon scanning the computer for fault codes, a P0102 code was found. The mass airflow sensor and the idle control valve were both replaced, however the P0102 fault and check engine light re-appeared the next day. I have found hundreds of complaints online for the identical problem that Buick Lesabre owners are experiencing with no solid "cure" for the problem. This condition is un-safe and renders the vehicle unreliable for driving.

While driving this vehicle the bolts on my rear brake pad broke in half and the car was unable to move forward, had to drive my car backwards home luckily I was only a block away from home. The 2 front windows will not roll up or down, keep having to replace the hose that leads to my radiator, when I make right turns the car vibrates, two front seat belts have stop locking all together and this vehicle has never been in any sort of crash or accident, front dash is starting to lift considerably. I adore my vehicle and I'm not looking forward to getting rid of it, but there are too many problems to deal with on this car.

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.

Transmission no longer shifts into 3rd or overdrive. With shifter in overdrive and in stopped position once you take your foot off the brake to begin acceleration the torque converter slams to a stop and the engine shuts off. Transmission fluid full at all times, engine warmed up. Repeated stalling, repeated tachometer quits. Repeated engine quits when you place in overdrive from neutral. Must start movement by placing in lower gears 1 2 or 3. this transmission never shifts out of second gear. Put it on code analyzer and got 2 codes that indicated pc solenoid torque converter solenoid issues. Seems like these 2000 Buick have recurring defects and GM won't standby their product. Why on earth would a company that designs cars ever put a battery under a car seat. One spark with hydrogen gas under that seat could kill an infant in a car seat if it exploded.. come on!!!
