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.
I had a repair shop replace the crankshaft position sensor,but it still quits running without any notice while driving it! What else could cause this problem?
These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. 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.
Due to a potential problem with seatbelt pretensioners, front seat occupants may not be properly restrained in the event of a crash, increasing the risk of personal injury. Dealers will replace both front the driver's and the passenger's lap belt pretensioners to correct this concern.

This unexpected movement of the driver's seat could cause a distraction, increasing the risk of a crash. Dealers will replace the height adjuster bolts in both front seats to correct this concern.
