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 pick a part to replace at random to see if it fixes the issue. There is no accountability here. Alot of elderly people drive these vehicles and they can't negotiate the car when this happens. When this begins to happen the car suddenly accelerates then sputters and dies. When this starts, if you keep patting the accelerator it sometimes helps to keep the engine running but not always.

The federal safety agency #: 04v090000 - I own a 1998 buick lesabre 3.8l. On 9/27/02 I had a hard starting and stalling problem, taken for service at gm dealer and fuel regulator was replaced. In august 2004 was notified of the recall and took vehicle back to gm dealer to assure the recalled part was not in the car. The dealer told us the car does run a little rough (noted on work order) but the correct regulator was in the vehicle don't worry about it. On october 10,2004 we started having trouble starting the car. On october 11 we made an appointment to take the vehicle in for service on october 18, 2004 to an independent service shop. On thursday october 14, 2004 and friday october 15, 2004 the car stalled once each day when moving in traffic at a very slow speed. On sunday october 17, 2004 while my wife was following me to drop the car off at the repair shop, the car again stalled. She put the car in neutral and restarted the car. When the car started it jumped forward and she struck the back of my truck. The repair shop found the fuel regulator to be leaking fuel into the vacuum hose and into the exhaust manifold. This was the part that according to the gm dealer was not part of the recall on august 11, 2004. The end result is there is $3000.00 damage to the lesabre, non to by truck. My back is slightly sore but of greater concern is the seat belt did not lock on the buick and my wife struck her chest on the steering wheel hard enough to have bruising in the outline of part of the steering wheel on her chest. In summary Im concerned about the 1.) fuel regulator, 2.) the car jumping and 3.) the seat belt not locking.
