The gauge has never been accurate since I owned the car. The gauge moves slower the closer it is to full, and faster the closer it is to empty. It also tends to say on or around full until it gets under bout 3/4 of a tank, then quickly jumps to what I assume is closer to the true amount of gas.

An example of the issue when the tank is at the fuller end: after filling the tank, it will stay at or around full for 2-3 hours of driving, basically a day trip to another area, but then the next day it'll be down around 3/4 of a tank or so after only 20-30 minutes of driving.

An example of the issue when the tank is at the lower end: If I have a quarter of a tank, go on about an hour drive, the tank will suddenly be near empty, catching me by surprise (or at least it did the first few times it happened).

The gauge is definitely faulty, but I'd imagine it would cost too much for a mechanic to figure out the cause. Honda should have looked into it.

I will fill up the gas tank to full, and the gas gauge will say 1/4 full or empty or 1/2 full. Sometimes I turn the car on and the gauge says empty. I turn the car off then on again and it show the correct amount of gas. I took it to Honda a few times. When I get there they turn my car off and make me wait, so when they turn the car back on the gauge is fine. They say I have to bring it in when the problem is happening, yet when I go in with the problem, they turn the car off every time and say they can't find anything wrong. Frustrating.
