   The 2015 ford fusion are very known for this issue with coolant lost and more recently I was driving and a warning popped up saying my coolant was over temps so I pulled over and turned the car off next thing you know my coolant was gone and I just filled it up. To make it even worse my mechanic told me it’s a known issue and ford doesn’t even cover it because it isn’t a recall

   Engine warning display came on with "cylinder over temperature" immediately after temperature gauge went from normal (slightly under 1/2 way) to "Hot" immediately. Shut off engine - opened hood, coolant was noticed on passenger side just below coolant bottle. After waiting a little bit the tempature on the gauge hadn't dropped any & the radiator was cool to the touch. The day before washer fluid was added, while there the other levels were checked after sitting all night,…

   I bought the 2015 ford fusion for my son as a graduation present as he headed off to college on his own. The car started misfiring upon cold start for about 5-10 seconds. Eventually the car started misfiring while driving. He frequently had to pull over on the side of the road while driving to make it to his destination. I had him take the car to a ford dealership to be inspected. To my surprise, Ford Parks of Wesley Chapel told me that the 2015 Ford Fusion 1.5L ecoboost has…

   I own a 2015 Ford Fusion SE. I bought it used when it only had 47,000 miles on it. Over the course of time since buying it in DEC 2022 until now, it has had low coolant that I have had to address but no visible leaks. Current mileage now is 87,100 and just recently the coolant was low again and the check engine light came on for DTC P0301 -Cylinder 1 misfiring. It has had rough start ups, rough idle, decreased acceleration, and poor fuel efficiency. I have found the problem…

   While driving at 30MPH, vehicle lost power without any notice/warnings. Had the vehicle towed to dealer who misdiagnosed as transmission problem (quoted $8000 to swap). Had a second opinion and indeed it was the dreaded coolant intrusion in the engine, catalytic convertor which cause the loss of acceleration and the transmission was completely fine. This is a ridiculously common issue with the 1.5L engine and Ford has not offered any support other than "oh well" mentality.…
