This vehicle has an "integrated" gas cap where the fuel filler door acts as the gas cap. I can't believe Honda engineering did ANY testing with this system since about 75% of the time when I fuel the vehicle, the nozzle gets stuck in the filler neck & the neck usually comes off the vehicle entirely when attempting to remove the fuel nozzle. This problem has been well documented on Honda/Acura forums for some time and I CANNOT BELIEVE Honda has not issued a recall as this represents a significant safety risk, not to mention potential emissions issues.
"fuel door stuck," "no manual override," "can't refuel." As per Acura manual there is way to open a gas/fuel door/cap/lid when actual way of opening through electronically fails due actuators or some other reasons. There is a manual release pull cable behind a removable access panel in the driver's side of the cargo area trim, near or behind the wheel well lining. manual fuel door release is inside the trunk (cargo area) in case the electronic fuel door release fails.
