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.

I have had this vehicle for 4 years and the speedometer has not worked for 2.5 years now. It will work if I reset the battery or turn the key over until the needle goes back to 0. I am told the instrument cluster is bad and I see that there are other complaints also. Please help. I need to know if this is covered at a GM dealership for free. The vehicle also sputters and I have already replaced the fuel pump and had the injectors looked at. If you can please email me or contact me I would greatly appreciate it.

The fuel gauge is not showing the correct amount of fuel. It will go far beyond full and way below empty. Over the course of a mile it can go from full to empty or all between.

The first incident we ran out of fuel with the fuel gauge showing we still had fuel in the tank. Next incident, the oil pressure gauge indicated a very high oil pressure reading, leading me to believe something was wrong with the engine. Took the car home and drove another vehicle until I could do some testing on the vehicle. Oil gauge returned to normal operation. In April of 2010 I was driving exiting an interstate highway onto a four lane road and the speedometer reading became inaccurate. I was traveling faster than the indicated speed. After stopping at an intersection the speedometer never moved from zero when I was moving down the road. This occurs after a brief period of driving. Mechanics I have spoken to inform me this is a common occurrence with this model vehicle. Gauges such as fuel gauge, oil pressure, tachometer and speedometer are not trustworthy and give inaccurate readings. This is a very expensive item to replace and should be considered a safety hazard because you cannot determine your speed at any given moment.

My 2004 Buick Rainier has a gas leak. I'm told that the plastic tank is the same one used with the GMC Envoy, the GMC trailblazer, old bravadier and perhaps others. The filler pipe welding breaks near the plastic tank and gas escapes. This is known problem and has been reported by many other GMC owners. This could be a the cause of fatal fires but GMC would rather ignore this safety problem.

Fuel tank is leaking at the filler inlet. This same problem was covered under a recall on Chevy trailblazer ext's which share many of the same components. There is a smell of fuel in my garage and it is clearly visible on my garage floor. Why wouldn't GM cover all vehicles of the same build and not just the trailblazer? I am afraid my car will catch fire overnight or while my wife and toddler are inside it.

  • 97,400 miles
2004 Buick Rainier with 97,000 miles and no history of accident, damage or service issues passed state of Arizona emissions test in December 2009, including evaporation testing. Within a couple of weeks a check engine light came on and was diagnosed by code as an evaporation issue. On the way to the dealer service center the vehicle would not accept gas, instead the gas puddled under the vehicle and caused the pump to automatically shut off. The dealer diagnosed that there was a crack in the gas tank in the area of the gas filler neck. The dealer also confirmed there was no damage to the area. Dealer indicates that the gas tank and filler neck need to be replaced. No action has been taken yet.
