Awhile back the car started making strange noises, that came from the fuel inlet behind the gas door, sounding like pressure escaping. Pressing the door in (capless fuel tank) confirms this, as the vacuum is released. Car idles rough, and in some cases, after refueling, it will immediately stall. Upon further research, it seems to happen to quite a few Fusion owners, with videos and forums posts to verify. Ford claims to not know of the issue, but just today issued a recall for a similar problem for the focus model cars. It is the 2. 0l turbo or naturally aspirated engines, and I have the 2. 0l turbo. There have also been reports of cars stalling while in motion. Check engine light came on today, with a p1450 code.
