2004 Buick Rainier Problems

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.

Bought my 2004 Rainier used with 28,000 miles on it, in 2006. I strive to take care of my vehicle with routine preventive maintenance however, despite my efforts I've had major issues with this lemon since shortly after purchasing it. I've had to replace every major component of the front suspension, the catalytic converter failed at 84,000 miles, causing an issue with the exhaust manifold, and...
