I never was informed of any recalls on my 1999 buick century. Now I see all the advertisements on television, in the paper, online that the car can burn up. Brakes, steering, ignition. Which was repaired for 400 dollars. My engine warning light is on constantly, and they can't find what's going on. Once, it just completely stopped.

While driving vehicle (1999 gm buick century ,120,000 miles) on at least 10 different occasions in the past 2 years the vehicle engine has stalled and all electrical power is lost. This has happened on the freeway while driving at 70 MPH, it has happened on city streets at 45 MPH.after the vehicle stops it can be restarted. There are no warning indicators displayed before or after. Initially the check engine light did not come on and there were no code diagnostics indicating a problem. The vehicle has been serviced 3 times. The gas cap, crank sensor have been replaced and the computer reflashed. The vehicle now maintains a constant small evap leak warning code and the check engine light is always on although the service mechanics cannot find any associated leak problem and the car drives perfect except for the intermittent and sudden engine stall and sudden loss of all electrical power . The vehicle has stalled on 2 occasions since the last service encounter. My internet searches indicate this is a big problem that few buick owners have been able to resolve for many years. I think the sudden loss of engine power and electrical power for steering, brakes, lights at any speed without warning warrants investigation. When this occurs at night on the road - suddenly no one can see you stopped in the middle of the road.

Unsure if this is an actual safety problem but it relates to transmission problems for our 1999 buick century. Since the problem could render the car unable to move at any time, I would classify it as a safety problem. Our service engine light came on a few miles back. We checked everything we could and finally had the problem diagnosed. We were told that the service code meant that a transmission component was slipping. I find that very troubling since the car has only 44,011 miles. We were also told by the same service center that a 2000 buick century that had 45,000 miles had the same problem only the day before. Is there an on-going investigation into this problem? Should there be?
