One problem related to radiator hose has been reported for the 1999 Buick Century. The most recently reported issues are listed below.
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. Im outraged that a car in this good of care is a big disaster. Recall is needed & I shoulda kept my 92 Century with the 3. 3 v6 it had 374,988 miles at trade in & still ran awesome:{ im so unhappy with this car I am ready to fix it and trade it off for a Ford lol.
