2003 Buick Century Problems

Engine -- Verified

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.

Engine -- Verified

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
 

Suspension & Steering -- Verified

The high pressure power steering hose will commonly leak fluid; it should be replaced.

Engine -- Verified

Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

Drive Train -- Verified

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.

2003 Buick Century Reviews

What can I say! I have driven a Volvo, several Fords and a Toyota and none of these vehicle compare favorably with my Buick. At over 300K miles (this is not a mistake) and counting, I have only had work done on the radiator recently. Outside of the normal wear such as brakes and some window issues, I have had no problems with this car. I intend to get another Buick Century.

Great car now at 130,000 with still no oil leaks! Did have to replace water pump at around 100k. The air conditioning in these cars is amazing!!!

Great gas mileage 32 highway. Had a problem with intake manifold failure due to GM Dexcoo 33k miles covered by GM.Had the transmission flushed at about 46,000 miles ,few weeks latter the transmission would slip then catch , had to have a rebuild at independent shop .They said any small problem can show up with fluid change. There are a number of valves that are open and close with the fluid and have some ware, as long as the fluid is thick no problems but with new fluid problems show up. Cost $1300.

Its a nice looking car. The Air Conditioner is fantastic. Its very conftortable to ride in and there is plently of room to fit my family. Gas mileage is decent, I have had problems with the drivers window not working and the water pump going out.

Too many little things go wrong around
50,000-60,000 miles.
