Vehicle was on 1/8 of a tank,I tried to fill, it would only take on 5 gallons of fuel, gas gauge read full. Reported to dealer, there is a 'bulletin' on the vehicle, fuel tank was replaced. After successfully filling tank 3 times, it happened again, returned vehicle to dealer, they could not replicate, brought vehicle home, dealer was able to fill tank with approx 13 gallons, I ran it to 1/8 of a tank tried to fill and it continues to only fill with 2-6 gallons, and record on the gauge a full tank.
