I've filled up on gas three times in the last five months. After every fillup, the HV mileage range on the dashboard increases dramatically. When I drove the car from the dealer, the range was around 350 or so miles. After the first fillup, it went up past 500 miles. The next time, past 700 miles. The last time, it hit 1000 miles, and even after driving with the gas engine on for many minutes, the range sat on 1000 miles. Now with around a half tank of gas, the range says around 750 miles. The electric range seems to be accurate. I finally went to the dealer to have them look at it. They said that Honda knew about this bug, but that they didn't have a fix for it. Has anyone else encountered this problem?
