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.

AWD does not engage. Very dangerous on a slick road. Had SUV to dealer 3-4 times. They never fix the problem. Front wheels of SUV make grinding noise after a few hours of driving. Headlights go dim/and even turn off for a few seconds while driving at night. Took to dealer, of course no problem was found. Someone's going to be killed because of both these problems with the Buick Rainier.

Headlights flicker on/off, and GM doesn't have a solution for this problem. Have contacted the manufacturer, and they cannot fix it. This happens intermittently.

Headlights dim while driving at night. The headlights some times flicker bright to dim then back to bright and the voltage gauge fluctates. This has escalated to where for no reason the headlights will go dim for approximately 5 to 10 seconds then return to normal, at this time they go dim enough that you can't see when driving and have to pull over. The service manager has spoke to GM and Buick representitives for the past couple of days and was basically told: There is a problem - we're aware of it - we don't know how to fix it.

The vehicle's engine has been sputtering, missing and surging since it was purchased. The vehicle was taken to the dealer but they were unable to find the cause of the problem. The vehicle battery failed. Water leaked through the front driver's side floor. Water also leaked into the vehicle by the hood release lever when raining. The passenger's side fender rattled. Headlight assembly seemed loose. Rack and pinion leaked.

In October, 2003 I purchased a new 2004 Buick Rainier. A couple months later my wife and I were driving home one night and the headlights suddenly dimmed and then came back up. It happened at least twice that night. We took it to the dealer and reported the problem. They were fixing several other problems at the same time so we assumed it was fixed. Last week, October 28, 2004, I was driving on the freeway over a dark mountain pass when the headlights went completely off. They stayed off for 2 to 3 seconds before coming back on. Luckily, I didn't crash because the lights of a nearby semi kept me from crashing into the freeway barrier. I followed the semi after that because I was afraid they would go off again. A few miles down the road, in a narrow on-lane construction area the headlights dimmed several times but never went completely out. Hen I reported the problem to the dealer the next day he was absolutely willing to do anything to fix the problem and understood completely how dangerous it was. But, the GM representatives and corporate office refuses to even recognize that there is a problem because it hasn't been replicated in the shop so will not authorize our dealer to find the problem and fix it. The dealer has called GM several time and I have called several times. GM basically told me that they didn't care if I died and/or killed other people as far as they were concerned there was no problem.
