Fuel gauge on our 2006 Buick ranier does not display the correct reading for the amount of fuel in the tank. It frequently reads empty when the tank has been filled, and then reads anywhere throughout the range of the gauge, changing while driving and or when shutting the vehicle off and re-starting. We never get a correct reading of the gauge, and therefore never know when we may run out of gas. The problem started during the fall of 2010 and remains to this day.
Irratic fuel guage beginning in Aug, 2010. Always fails after complete fillup. Sometimes operates below 3/4 tank. Currently not operating at all for past 90 days. It is showing "low-fuel" warning light irreguardless of the amount of fuel in the tank, the guage needle remains on empty. There is no way to know how much fuel I have or when my 2006 Buick Rainier will run out of fuel.
