2019 Ford Fusion: hesitation when accelerating

Filed Oct 6, 2025 · Engine, Fuel system · NY

According to Auto Zone, after being placed on scanner, the power train system (P0456) has a evaporative emissions system leak (very small leak) diagnosed at 76,919miles. Ford dealership says they cannot find a problem. When I put gas in the car I have to sit and wait at least 10 minutes before my car will start again. It takes a couple of tries and much hesitation, but it will start. Once you get started it has difficulty accelerating or may slow down on its own. Again, Ford dealership reports they can't seem to find a problem. When I told them the problem, they came up with a price to charge me to fix something they could not find. Ridiculous!! My ford app clearly states check engine problem detected, but nooooo they cannot find anything wrong. Two different dealerships. Thank God I keep my paperwork because others are complaining of the same thing. They have to put the pen to the paper or we will never get a recall.
