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

After following online advice of flushing and refilling center differential fluid several times the problem still continued. Took it to dealership and the finally figured out the servo motor in the center differential was bad.
