2000 Buick Lesabre: engine stalls while driving

Filed May 2, 2022 · Fuel system · IL · fire

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.

Car stalls while driving

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.

Starting early june my son called me to inform me that the buick was stalling out on him all the time. He said that he could be driving at any speed and the car would just shut off, causing all electrical, steering, and brakes to not work. He attends school in western pennsylvania in the mountains and this worried me. I had the vehicle serviced and each time was diagnosed with different things and nothing fixed the problem. I have since switched vehicles with him for his safety and have contacted my local buick dealership to find that the ignition cylinder is the cause of the failure that the ignition cylinder is periodically loosing connection to the key which has a chip in it (quits talking to), and shuts the vehicle off. Like an alarm feature. The dealership informed me that this has been an on going problem with the lesabre and other vehicles for quite a while. In order to fix it I will have to purchase a new ignition cylinder, possibly a couple of keys, have them sent to a locksmith, get them keyed to the cylinder, then install the new ignition cylinder. Yet it is not one of the vehicles listed on the gm ignition recall list. How can such a safety issue go overlooked and also unreported. The vehicle is an excellent vehicle while running but I feel that gm should face the fact and take ownership for all of these ignition failures not just a few makes and models but all gm manufactured vehicles. This is an extreme safety issue, my son said he was nearly rearended when the vehicle shut off on him a number of times at different speeds while trying to pull off the road for safety. Or he was stuck holding up the flow of traffic with people beeping at him while he had to wait in the middle of the road till the car would start again. Pretty scary!!! Thank you,! And please look out for the little guy and hold gm responsible.

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 buicks 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!!!
