There are 2 owner-reported fuel system complaints for the 2020 Subaru Foresterin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Much like the 2018 Outback issue I had, my 2020 Forester is having the same issue with fuel indication inaccuracy and mpg increasing when fuel level gets under a quarter of a tank. My local Suburu dealership said this is not an issue for this model. I have reported this to Suburu as well. Previously, Subaru found that the software that controls the fuel system can cause the fuel gauge to show that there is still fuel left in the tank when there isn’t. More specifically, the low fuel warning light may not actually come on, and the miles to empty display could be inaccurate. The software is causing additional miles to be showing when they are not available. I don't know if this is a similar issue or not, but no one has fixed it. With any vehicle, you need to be able to rely on the fuel gauge. Knowing how full (or empty!) your gas tank is extremely important when driving, particularly if you are driving a long distance. If you do run out of gas, the engine can stall; fortunately, the vehicle can be driven to the side of the road if it stalls when you are in motion. As the issue involves a software bug, it is easily fixed by the dealership.
BOTH MY WIFE AND I HAVE RUN OUT OF GAS ON THIS VEHICLE WHICH HAS LESS THAN 5,000 MILES ON IT. THE LOW GAS INDICATOR IS LIMITED TO A BRIEF WARNING IN THE SCREEN BEHIND THE STEERING WHEEL. WE BOTH FIND THIS VERY EASY TO MISS AND THERE IS NO PERSISTENT VISUAL OR AUDITORY WARNING. RUNNING OUT OF GAS UNEXPECTEDLY IS AN EXTREME SAFETY HAZARD, WE WERE LUCKY TO AVOID BEING REAR ENDED, BUT HAD TO PARK AT SOME RISK. NEITHER OF US CAN RECALL RUNNING OUT OF GAS IN OUR OTHER VEHICLES FOR OVER 20 YEARS.
