Hi I recently purchased 2019 model and have noticed when I fill the car up to full I had 500 miles on my clock I drove 15 miles home and it now reads 380 miles it’s lost 100 miles I asked mitsubishi and they said it’s the way you drive ? Any ideas as this definitely isn’t right

My first recommendation is don't trust the estimates shown on the dash until you get a good idea of your actual mileage. What's displayed could easily be skewed by current readings. In your example, you pull up to the pump after driving for an hour and averaging 32 mpg. When you fill the tank, the ecu reads volume at listed capacity which is 15.5 gal (U.S.). So if you continue to get 32 mpg then you can drive 496 miles until empty, or ostensibly 500 miles. I do believe filling the tank resets the mileage calculations. Then you drive home through town and average 22 mpg with traffic. Now that same 15.5 gallons will only get you 341 miles until empty, if you stay with city driving.

Do you know what your actual average mileage is based on actual miles driven/gallons to full?

Flip over to the fuel economy screen for a bit and see how things look there. If I start up and let it sit for 5 minutes before setting off, it'll often show like 40L/100 initially then settle down to 17L/100 for city traffic with stoplights, then the 7-9 range when cruising.. range estimates always pick up once I'm out of the city (or I'll drive 100kms without the range dropping).

10 miles in town I'd believe the low range estimate.. Was traffic on the drive back from work much worse than the way there, or at least the last 15 minutes of each?
