Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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.

Rainier 6-cyl

  • 56,000 miles


Approximately 6 months ago after getting gas at a gas station, I noted my gas gauge in my 2006 Buick Rainier to read "empty" despite having just filled it with gasoline. For a short time afterwards, my gas gauge fluctuated despite my gas levels. My check engine light also came on every time I filled up my tank. Still to this day, my gas gauge continues to read "empty" all the time despite filling it up with gas. Therefore, I never know exactly how much gas I truly have in my gas tank at a time and worry about running out of gas frequently.

I was just informed of a recall on my above listed vehicle. Please note that my fuel gauge was not reading correctly as it was displaying empty while the tank was full. I brought the vehicle to my GM dealer immediately to diagnose and repair. It was determined that the fuel sender needed to be replaced. The total repair cost me $571.77 which included parts and labor. Who do I need to send a claim to in order to be reimbursed as this repair is now considered a recall?

The contact owns 2006 Buick Rainier. While driving approximately 50 mph, the engine service warning indicator illuminated and the fuel gauge registered an inaccurate reading of zero. The failure occurred whenever the vehicle was in motion. The vehicle was taken to an authorized dealer where they replaced the fuel gauge sensor. The failure mileage was 54,414.

On few occasions I run out of fuel because the defective fuel sensor unit in the fuel tank. One time it happened on the busy highway. This defect can lead to very dangers situation. The fuel indicator becomes erratic and unreliable without any warning. There are a lot of complains on the internet about fuel sensor in GM SUV's. same part is used in all GM models (2005-2007).
