2005 Buick Rainier ProblemsRear Suspension Low Due to Failed Air Compressor
On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.
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.

Owners have reported several instances of the air conditioning not blowing through main dash vents, or only blowing through the floor and defrost vents. Often this is experienced after replacement of the battery. During battery replacement, the control module for the mode actuators may lose its memory. Re-calibration of the actuator is required to address this condition.
