While merging onto i95 north my car shut completely off in the middle of moving traffic. I didn't even realize it was off until my little girl asked me to turn the radio back and my speed begin to decrease. It's very difficult to steer such a huge tank like my lesabre when the power steering gives. It cranks right up after shutting off as if nothing is even wrong, but this has happened always in stop and go traffic. It bothers me because my car is all I have and it's the only transportation that I have for traveling with my little girl. *Tr

Buick lasabre dies on highway while driving. Looses all power causing the driver to have to try to get off the highway while in heavy traffic while under no power. No brakes, power steering . Happens about 8 to 12 times a day. I drive 47 miles to work. Almost got rear ended 8 times, had to make unsafe turns to keep from having a dead car in the middle of the road to get totaled. Replaced coil packs per dealership recommendation. Still dies. Not even the dealership can diagnose the issue. Seems all mechanics want to...

Tl*the contact owns a 1994 buick lesabre. The vehicle was purchased in july of 2008 and continues to stall while driving 50 mph or less. The vehicle lost power and the engine completely shut off. The weather conditions were dry. When the failure occurs, the vehicle becomes difficult to control because there is no power steering or braking ability. Occasionally, the vehicle takes longer than a minute to restart. The vehicle has to be towed to the dealer each time. The vehicle is currently at the dealer, but they cannot diagnose the cause of the failure. The failure mileage was 125,000. Updated 12/12/08 *cn updated 12/15/08. *Jb

I am a mechanic and work on cars. I have noticed that the gm cars of the early to mid 90's like the buick le sabre class are have a problem with the heater enclosure in the engine compartment. *Tr the plastic enclosures are cracking and pieces of it are falling off, and if you touch the plastic, is will crumble apart. I fee that this is a serious health hazard, as this will allow the fumes from the engine like exhaust,gas and oil to enter the passenger compartment. Then the occupants will be breathing the fumes. I feel that gm needs to do something about this. *Tr

Wife stranded when car overheated. Upon inspection of engine I found that the plastic fitting in the intake manifold had broken off letting all coolant run out. We have been loosing coolant for some time. (A year and a half ago I replaced pump, thermostat and serpentine belt while traveling, but always had a loss of coolant that I could not find. When I called to get a new fitting, the attendant told me what the problem was before I could tell him. He said this happens a lot and that the replacement part is...

While driving vehicle stalled. Consumer had not had the vehicle serviced, except for the oil being changed.*Ak

Smell of gasoline around the car. A check under the hood show drops of gasoline coming from around a small clip in fuel line (top of the engine near the firewall). This is not the first time for me! Last time the fuel was coming out of the clip at a faster rate. Last time I wasn't able to replace the clip without buying an unrelated repair kit (discarding other parts) . I consider the condition, especially when the leak becomes more serious and driving the car for a while, as very serious. *La

The vehicle leaked coolant. The vehicle was taken to the dealer for repairs and the intake manifold was replaced. *Jb

The problem is that the car will die while driving and I have to coast over to the shoulder of the road and stop. The car will not restart and I have to wait about 5 to 10 minutes before it will restart. This has happened 3 times (twice during the week of 3/13/00). I brought the car into the dealer but they were not able to find the problem. I am still driving the car but I feel it is a very unsafe situation as a very bad accident can happen when the car stalls out at highway speeds. *Ak

While driving about 35-40 mph vehicle would downshift then upshift for short periods of time, and finally stall. Vehicle was taken to the dealership. Vehicle was road tested three times .

While driving at any speed consumer noticed smoke coming from the front of vehicle, and determined that the problem was within the cooling system. When the vehicle is cold there is steam coming from the front of the vehicle, and there is an odor in vehicle. Also, throttle body seal may bnot be sufficiently compressed to prevent coolint from leaking. *Ak
