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.
2004 Buick Rainier fuel system complaints
Page 2 of 2: complaints 11 to 18 of 18, newest first, as owners wrote them.
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.
Tl* the contact owns a 2004 buick rainier. He stated that while the vehicle was parked, he noticed a fuel leak. The dealer was contacted and they stated that they were aware of the issue and did not have an explanation for the cause of the failure. The vehicle was not repaired. The failure mileage was 117,000 and the current mileage was 118,000. Updated 9/1/10 *cn received pictured. Updated 09/21/10.
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.
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.

2004 buick rainier speedometer & gas gauge went haywire at 43,000 miles. The needles pointed randomly and the gas gauge showed 180 degrees off the markings, pointing straight down. Complained to the dealership, who stated this was a known defect and replaced the entire unit for a $100 deductible even though the car was out of warranty.
