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.

2006 Buick Rainier Owner Comments

problem #1

Jun 012016

Rainier Limited 5.8L

  • Automatic transmission
  • 166,458 miles


Over the past several months when I come out in the morning to leave for work, my Rainier won't start until I tap on the circuit breakers and fuses near the battery. Once I get it started it usually restarts for the rest of the day. Lately, the engine stops running like turning off the ignition while I am driving down the road. Same work-around, I raise the hood (after pushing my truck through traffic to safe shoulder) and take the cover off of the fuse/relay panel near the battery and pound on it and wiggle the wire harness and then it starts up again.

I have removed the circuit panel and cleaned all of the contracts, I have tested all of relays and swapped them out, I have replaced some of the fuses (thinking there might be a hairline break that I cannot see). Please help.
