“As the 3rd owner of a 1999 Buick Century limited I did a thorough search of cars history and found no problems until today 8 9 2013 when I took it in for radiator hose change cooling system flush and oil change which later was told allthey could do was the tranny flush because of the intake manifold gasket leak which im hearing is a huge 3.1 GM engine problem. Uppon calling the former owner she informed me that at 50,000 it was replaced and again at 108,765 miles. It now has 137549 miles and iy has again taken a dump I hear a coolant type conversion can help my $700.00 problem. …”
NHTSA complaint #10534572, filed 2013-08, 137,549 miles“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. …”
NHTSA complaint #10031070, filed 2003-08, 43,995 miles“I pulled into a parking space on a slight incline and was just releasing the brake pedal to move forward when the car lunged violently forward as if the gas pedal was to the floor. There was not enough time to do any thing expect a reflex to turn the wheel to avoid hitting the building head-on. The car scraped the side of the building only stopping when it hit a van. After the car stopped moving, I put it in park and turned off the iginition. The impact was not strong enough to deploy the air bags. My feet were not on the brake or gas when this occurred. …”
NHTSA complaint #10041034, filed 2003-10, 38,920 miles“The contact owns a 1999 Buick Century. The contact was driving approximately 50 MPH when the check engine and track off warning lights illuminated. The vehicle was later towed to a local mechanic where the contact was advised that the ABS sensor and other wires were bound by electrical tape and the fuel and brake lines were corroded. In addition, there were missing plugs which prevented water from entering the vehicle on both the driver and passenger sides. Both the brake line and the transmission were leaking fluids. …”
