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 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.

I had involved car accident which from they called throttlebody due to (tps...shift by wire) you can find in ask.com encyclopedia *(see bottom) that I experienced which I had. It was running in reverse and hit steel post that protect gas meter while I tried brake but engine and tranny was in full idle and I tried change to into drive while it still in full idle and my brake cant stop until I hit emergency brake and turn engine off by key switch. I did some research and found I'm not alone and my insurance (national general which used be gmac) pushed my car into totaled that they used by Nevada law and body shop trying to send this car to dealer for testing but never happen cuz of totaled processing. Which leave me puzzled and found out that my car sold to body shop and repaired and sold other people. My worry is if they not testing throttle and other people who bought this car may face risk which I had. *disadvantages the cost of dbw systems is often greater than conventional systems.that fall under the category of safety critical systemswhich are recommended to be developed under standards like iso 26262 which require extensive changes in the development process generally taken for developing other traditional systems..

The contact owns a 2006 Buick Rainier. The contact stated that while driving approximately 55 mph, the air conditioner failed to operate. Additionally, the transmission emitted a loud whining noise. The vehicle was taken to an independent mechanic where the blower motor resister was replaced. The failure recurred after the repair was performed. The vehicle had not been repaired for most recent failure. The manufacturer was not made aware of the problem. The approximate failure mileage was 102,000.

Rainier

  • 56,482 miles
I would like to start by saying I love my 2006 Buick Rainier and do not want this experience to break my commitment to GM products. My problems began when my Rainier started having problems turning at low speeds and backing up. My 2006 Rainier only has a little over 56,000 miles, so as you can see my SUV has very little wear and has had all the regular schedule maintenances. I did experience the bumping noise periodically which I understand now is a precursor to the transfer case going out. I have written to GM about the problem with the transfer case to see if there was any way they could provide assistance with this problem as it has caused a financial hardship with the replacement of the transfer case costing a little over $2400. GM responded that there wasn't anything they could do about the matter. The service dealer has been very gracious with me and working with me to arrange payments each month, however, as with any business they are a business and must continue on. I have seen on the edmonds car blog that there are almost 300 entries of this very same problem with the transfer case going out in this particular vehicle. I am pleading with you to investigate this issue as it isn't only about the financial hardship it has caused me but mainly the safety issue it could have caused when I couldn't turn or back up appropriately which I could not when the transfer case went out. I purchased my Rainier originally because I had a trailblazer ltz and saw how the Rainier was a better kind of version or more luxury version of the trailblazer ltz. I am beginning to wish I had kept my trailblazer of almost 200K miles to my Rainier of only 56K miles. Your assistance in this matter is greatly anticipated and appreciated.

Rainier 8-cyl

  • 38,000 miles
There are two kinds of problems I brought to the attention of the service department several times since purchasing the vehicle but mechanics still cannot find what is causing the problems. First, my vehicle stutters when I back up and turn slowly or turn forward slowly. It does not do it every time, just occasionally so the mechanics do not experience it. Second, when stopped at a red light for a few seconds, my car feels like it has been hit in the back but when I look back to see if I've been bumped, there is no vehicle behind me. It feels like the powertrain or engine wants to jerk forward. I've taken it to the dealership twice and they say they have fixed the problem, but it continues.
