About 90% of the time, my gas gauge on my 2005 Impala works just fine. However, sometimes on hot afternoons it has problems & it doesn’t read accurately. For example, I will have a nearly full tank & the gauge will show 1/4 to 1/2 full, depending on its “mood”. If I drive the car somewhere & turn it off, everything is fine after I re-start it. I have to drive it somewhere though. If I start it, turn it off right away, and re-start it, it still reads inaccurately. Any thoughts on what might be causing this?
The car runs fine & there no warning lights are lit on the dash.
