NHTSA — Fuel System, Other Problems

CarComplaints.com Seal Of Pretty Good

CarComplaints.com Notes: The 2006 Buick Rainier has a lot going for it and just a few issues that keep it from making our "best vehicles" list.

The good news is the SUV has a quiet interior (thanks to triple door seals, acoustic laminate glass, and thicker sound-absorbing pads), a low number of overall complaints, and a RWD system which offers good balance and handling.

Unfortunately, it received poor safety ratings in crash tests, owners report that the gas gauge is unreliable, and there was a large recall for melting power window switches.

So close, Buick. So close.

My 2006 Buick Rainier has a gas gauge that does not register any fuel in the tank. When the problem began the gauge would go up to the whatever level of fuel was in the tank but now it registers empty all the time. I have taken the vehicle to repair shop and found out this is a pervasive General Motors problem with these types of vehicles. The repair is going to cost between $300 and $400 to repair.

Gas gauge failed at approx. 75000 miles. After researching on line, this seems to be a defect in the gauge inside the fuel tank.
