I noticed it once and I thought maybe I was enjoying myself driving around town. I haven't noticed it again after some reflashes from the dealership when correcting other issues I had. Ill have to keep an eye on it. Maybe im sleep driving again. .I'm not sure if you are feeling the same... I feel like Supra is picking up mileage while it's parked... I didn't go anywhere but it's been accumulating over 100 miles every day..
