I had 20 miles left then the gauge started flashing saying low on gas and my estimation on how many miles left turns to 0 miles. Then I went to refill the car, it's still saying 0 miles left. Anyway on how to fix this? Btw, I'm new to this forum, but I'm wondering how many mpg are you guys getting. I get around 55+mpg from home to school everyday (3 miles) at 60 degrees (oF) in California. I use ECO Mode most of the time and EV mode when I'm in parking lots. I often don't push the gas pedal to the max because I know there's going to be a right light in front of me.
If you fill a couple of gallons, it wont adjust. If you fill the whole tank, the first few feet you drive forward will update the DTE.
