I have had this problem twice now on my 2017 CMAX Energi. The "fuel door opening" message comes up on the dash as it should when I press the fuel door release button, but about twelve seconds later, the "Refueling error: see manual" message is displayed. First time it was fixed under warranty. Now, a year and a half later I have to pull the emergency door release (behind the black plastic panel) every time I need to fuel up. The Ford dealer says it is fuel tank pressure problem. FTP reads 1.37 when it should be between 1.40 and 1.50. They want $835 + tax to fix. Too much in my view, especially as it was already "fixed" once... Did you find a fix? Please let me know what it was and cost if you could. Thanks!
