Pontiac Bonneville Problem Report
Pontiac Bonneville Erratic Fuel Gauge Operation
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The guage will show that I have more gas than I actually do. - Barbara1963
Fuel gauge swings back and forth when it shows 1/2 full. When full tank reaches 1/2 mark it starts jumping around. I set the "fuel remaining" readout and when it show I only have 2/3 gallons left I fill up. Too costly to replace sensor & fuel gauge! Otherwise great car. - Visitor
Fuel gauge no longer relates to amount of fuel in tank, told it was part of the fuel pump which would need replacment. - Visitor
Fuel gauge registers over full or near empty when tank is 20% to 90% full. Have to monitor fuel level by mileage. What a pain!!! - Visitor
My fuel tank guage will read 3/4 full when I park it on the lot in the morning at work. When I get ready to leave work it shows 1/4 full?? Thought someone was siphoning my gas! - Visitor
Car doesn't run well when the ac is on, or when we drive uphill. It struggles to fire up when you turn it off a lot of times. - Visitor
gas guage drops to empty. - Visitor
The gas gauge does not read the fuel level correctly, so I have to use my trip reset to give me an estimate as to how much fuel I use before I fill it back up. This car is a lemon...way too many problems to count!!!!!!!!!!!!!!!!!! - Visitor
Fuel gauge went haywire. Fuel take sensor had to be replaced. $174 just for the parts. - Visitor
Fuel take reads incorrectly - Visitor
This car has a lot of problems with the Fuel gauge/ fuel pump. There's kits you can buy to replace the gauge sender or the the fuel pump, but since it's common for both to go, you might as well change the whole unit since you have to open up the access panel in the gas tank anyways. - Visitor
