2002 Buick Century Problems

Intake Manifold Gaskets May Leak Coolant or Engine Oil

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.

Power Window Switch May Fail

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

Transmission Pressure Control Solenoid Failure May Cause Erratic Shifting

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.

2002 Buick Century Reviews

I bought this low mileage one owner car as a work car. This was my 6th Buick. Between the rocker panel rust, window motor replacements, and errant engine light problems, within a year I sold it. I will never buy a Buick, or any other GM car again!
Just bought a 2002 Century used. 60,000 miles. Like the car so far for ride and feel. Just changed the oil and filter and that turned out to be more of a pain than I'm used to. Attempted the air filter and the replacement didn't seem to match up with the owners manual. Finally gave up and will take to the shop. Hopefully all of the "basic" maintenance isn't this difficult
I absolutely love my Century... it has been a wonderful car with very little repairs, other than normal wear and tear... I'm pushing 150,000 miles and can't complain. Still get 22-25 mpg around town and the car continues to run well. Excellent choice for someone looking for a reliable vehicle!
