Fuel tank: Tank leaked when it was filled. Most of the time in my driveway but occasionally in parking lots unstil the tank level was reduced to approximately 3/4 filled. In addition fumes would fill the air surrounding the car. The automobile is being currently repaired at an independent repair facility. No other inspection other than repair facility. Initially no warning light but as it progressed the "check engine light" lit. Inspected the removed gas tank at repair facility and the caused of the problem may be a design flaw. the tank design on my vehicle (all wheel drive) is such that it has two zones and each zone has a fuel pump. The retaining plates on the tank are made of metal and therefore due to New England winters and the position of the tank and the location of the tank the retaining plates rust. …

Codes P0300 P0301 P0316 - My son was driving and approached a red light - his car began to idle rough and check engine light came on. Instructed him to park the car and we towed to a local mechanic. Cylinder 1 was misfiring and also had a mix of oil, fuel and possibly coolant in Cylinder 1. Apparently this is a defective issue with a 2014 Ford Fusion with a 2.0 Ecoboost Engine and also lawsuits regarding this. Ford dealership confirmed this is a sore issue with Ford and referred to Ford Customer Service --- no assistance and just advised to hold onto receipts in case it is a recall issue -- this is not okay at all. Ford has had plenty of opportunities to correct this with Ford Fusions but still have not!!!!! Very very very upset!!!
My engine light came on. Code is PP0456 - evap leak. Dealer found that gromet/seal on tank is failing. This part is not serviceable, so the entire fuel tank needed to be replaced. After dealer discount, the cost was $2242.24. Dealer is Larry H. Miller Ford, Mesa, AZ, phone [phone]. I have owned many Ford vehicles since 1978 and never experienced such an expense. In my opinion, this is a design issue since the rubber seal is not serviceable. This experience is causing me to lose faith in the Ford brand. Is FMC willing to assist with this expense? Please note - this vehicle has only been serviced at the dealership.
The flex plate on my vehicle was cracked. Which damaged the transmission pump. We heard what sounded like a box of rocks which quickly got louder and louder we took the car to the dealer the next day. We had no other warnings something was wrong no engine light or anything. Had this plate broken completely we likely would have crashed and our small children could have been hurt. We took it to our local Ford dealer who diagnosed the issue, but would want over $6000 to fix the issue, on top of the $225 we paid to get the issue diagnosed. So for the forseable future we have no safe vehicle.
