Okay, they tell me that because I keep my fuel tank mostly full that this caused the gas gauge to stick at full. Even though it was under warranty, at first they gave me some BS that it was the gas cap and that it was unscrewing itself and causing the dash light to come on. After charging me for a new gas cap and a computer diagnostic charge(not under warranty), I left the dealership and the light came on again about 20 miles later after I got gas. Then they had to schedule a 2nd appointment & order a new fuel pump and charged the $100 deductible. All together it was over $300 & it should only have been $100
