2004 Buick Rainier Problems

Air Compressor for Rear Air Springs May Fail

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

CD Player in Radio May Fail

The CD player in the radio may fail. Our technicians tell us that the radio will need to be removed and sent out to a radio repair shop to correct this condition.

Fuel Level Sensor Failure

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.
