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 Buick Rainier is a replacement for the Oldsmobile Bravada, hopefully minus the transmission issues and AWD complaints.

2004 Buick Rainier Owner Comments

problem #1

Dec 062003

Rainier 6-cyl

  • Automatic transmission
  • 600 miles


A 2004 Buick Rainier with full time 4 whell drive and locking rear differential which my wife and I bought the last week of November has a severe safety problem. The car slides out of control on corners under the slightest acceleration when any snow is on the road. The car was brought back to the dealer twice, the secound time I was told by one of the owners of mack Pontiac, GMC, Buick in hicksville, NY, rodney gomez, that all 2004 Rainiers have the same problem because of the locking rear differential. I realy think you should look into this as it is a very dangerous situation. Thank you.
