Fuel Gauge

[pbinde]

Wasn't sure where to put this one. I got into my 2023 telluride after lunch yesterday and the car showed that it was beyond out of gas, not range nothing. So I immediately found a gas station on my route ($2/gallon more than I should have been paying :-( ) and put in 4.5 gallons to get me back to where I could then fill it up more affordably. when I started it back up it showed a full tank. So was obviously not empty. I have never had this or any car show that I was empty when I was not. Is this something that I need to get checked out? A fluke?

I don't know if this helps, but I occasionally had a similar problem with my prior car. The gas gauge would show the tank as near empty, but when I went to fill it up, it would only take 5 or 6 gallons. It basically was a sticky fuel level gauge in the tank. I would then add a can of SeaFoam motor treatment before filling it up and that always cleaned up whatever gunk was causing the gauge to stick within 100 miles of driving. I ran into it every couple of years. The fuel level sending unit is inside the fuel tank and is a physical lever with a float. I'm lazy and always start off with trying the simplest solution, especially if it can't hurt.

I also found a TSB that might help. ELE328 - CLUSTER SOFTWARE LOGIC IMPROVEMENT FOR LOWER THAN ACTUAL FUEL LEVEL INDICATION - This bulletin provides information to upgrade the software on the instrument cluster ‘CLU’ on some 2023-2024MY Telluride (ON) vehicles equipped with a 12.3” in. TFT display, produced from September 15, 2022 through July 18, 2023, which may intermittently show a lower fuel level than what is actually remaining in the vehicle upon starting the engine after refueling.
