2000 Buick Century Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2000 Buick Century

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

One or more power window switch may fail. The affected window may work intermittently before failing completely.

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

what did I miss.

I stopped at a red light and when it turned green I pressed on the gas and it went nowhere. The transmission was not slipping or showing any signs of failure. The car starts great and the automatic shifter moves freely. Is it the tranny? Torque converter? Or something more simple?

No tail,backup, or licence plate lights in trunklid. Found a burned wire, maybe ground but can't find source. Wire burned from right rear qpanel to light plug in trunk. Is this common? Went to to junk yards for that wire harness and 2 other Buicks had same burned wires. Dash lights work when ...

I did have to have the exhaust manifold gasket changed cause it was leaking coolant in and out the engine. Two of the windows no longer roll up or down, the Check Oil light is forever on, as is the Low Coolant, and Service...

GM could not GIVE me one of their cars ever; have 2000 Buick with approx. 130,000 miles; Transmission went out twice at cost of $3500; all window motors went out twice; Heater/Ac blower switch went out twice at cost of $700 each time; electrical problems brake lights; my dash cluster doesn't light up; this car should have been re-called. Next time, I'll buy foreign like Toyota.

Got this car at 95,000 and now has 110,000 with no repairs since purchase. Really drives nice and with the exception of window problems has been a great car.
