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.

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.
