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.

Buick Rainier 2006, [xxx], I have had trouble with my SUV turning off while driving many times. Also, it will not start after several attempts until it just wants to. Now, it has completely stopped starting and is sitting in a parking lot after trying to start over 5 hours, I am so upset and stranded. My VIN does not appear on recall list for switch, but that is the trouble I am having. What do I do now? information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
