Buick Rainier Repair and Maintenance

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

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.

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.

Fluid may enter the driver's door module, causing corrosion that could result in a short circuit in the door module. A short circuit may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing an odor, smoke, or a fire. Dealers will inspect the driver's door module, if it is functioning correctly, a protective coating will be applied. If the module is not functioning correctly, it will be replaced. The GM recall number is 12180.

Vehicles first sold, or currently registered, in certain states where salt is used to de-ice the roads are being recalled because fluid may enter the driver's door module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing an odor, smoke, or a fire. As of this time, the remedy plan is still being finalized and a notification schedule has not been determined. The GM recall number is 12180.

I need a repair on the rear air springs, the air compressor has failed causing the rear suspension to sit low. I also need to get the front Differential rebuilt. Has anyone had any of these repairs done and at what cost???

I purchased my Rainier new in 2006. I now have over 195,000 miles on the vehicle. It's been an incredible vehicle. The best vehicle I've owned. The only reason I'm at this site is because I can't find the low pressure port to charge my AC.

I love my Buick Rainer CXL! Only problem I have is I can't find a Chilton's manual!!
