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

  • Manual transmission

At highway speeds (50-60 mph) accelerator became inoperative...I.e., no connection with engine. Used "resume" button on cruise control to speed up. Many months ago same thing happened. Could be very dangerous. Just intermittent.
