Hey all, I've had my 2013 fusion for just over a year now (2nd owner) and it's just about to be at 40k miles. Maybe 3.5k miles ago the P144C error code came on, but I didn't see any issues with the performance and MPG then just last week I started hearing an intermittent buzzing noise coming from the gas cap and then spluttering and stalling after filling up with gas. I checked my bluetooth ODB sensor and I got P0456, P144C, and P1450 showing up. I'm going to make an appointment for my car at my local dealer ship, but I'd like to know if I'm in for some big fixes. Thanks,
