2005 Buick Rainier Fuel system Problems

“We filled up the SUV and the gas gauge did not register that the tank was full. After a while the gauge slowly moved up and showed that the tank was full. After a couple of weeks of that, the gauge now does not move off of empty at all. Often times the gas reminder signal goes off letting us know that the tank is empty, however we had just filled up the tank.”

“No gas gauge, it reads empty even when the tank is full. Low fuel light is constantly on, and when I am truly getting low on fuel, it may bounce to an area between e and 1/4 tank mark. I am having to pay attention to the miles I drive and hope that the mpg at 15.9 is accurate since nothing else seems to be.”

“Malfunction of fuel level sensor. In september of 2009, the fuel gauge in our 2005 Buick Rainier began registering empty at all times, even when the fuel tank is full. The problem has been diagnosed as having to do with a malfunctioning fuel pump module assembly. This problem seems to be happening with GM vehicle of this type include the Rainier, blazer, jimmy and so. I believe this is systematic problem through this family of vehicles and is dangerous as the fuel gauge will not accurately read the fuel level.”

“I have been doing research and I have noticed that there are many people that are dealing with the same issues I am which includes gas gauge failure (false readings) and speedometer reading incorrectly. The amount of people dealing with these issues should be enough to place a recall on those clusters I would think. I have never had so many problems with a 2005 vehicle before like I have had with my 2005 Buick Rainier. I have ran out of gas many times because of this issue leaving me stranded on the side of the road. Something has to be done.”

“Three years ago the fuel sensor on my Buick rainer failed. Gm has issued a bulletin on the repair that covers 50% of the cost. I view this as an acknowledgement from GM that there is an issue with the sensor. I took the vehicle to a Buick dealer and they informed me that the out of pocket expense to repair this item is around $200. After numerous calls to customer service I gave up on trying to get GM to cover 100% of the cost. After talking to your office I understand that the engineers are still looking into this issue. Do you know when this will be resolved?”
