I bought 2022 Venza LE 3 days ago. Yesterday it’s was showing 3/4 of the tank after drivin about 190 miles. It showed about 350 miles to empty. Today I drove additional 40 miles and the tank shows as full! Over 450 miles to empty! Nobody has filled the tank. And when I drive in in Echo mode it’s shows 54 MPG! Idk what’s going on. The fuel grows in the tank. Taking it to service tomorrow. Very upsetting.
