Buick Repair and Maintenance

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

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

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 oil may leak from the valve cover area, which can cause a burning odor and increase risk of fire. Dealers will replace the spark plug wire retainer to redirect the dripping oil on affected vehicles, and will replace the left valve cover gasket on vehicles with the 3.8L V6 supercharged engine.

Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

The chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.
