Automatic Transmission Control Module problems of the 2015 Ford Fusion

The car recently misfired 3 times. I took into get oil change and have the misfire checked into. The misfires started 11/4/21. Car would run rough and then stall out. It would sit for a minute or two and start and run fine. There were no check engine lights or gage to show the car was running hot. I never dreamed it was a cracked cylinder. The dealer performed eec test diagnosis and found previous misfies in cylinder 1 in mode 6 of pcm. Found coolant level low, pressure tested cooling system and found that cylinder 1 with coolant intrusion. Short block replacement. I see online that there have been recalls on 2013 -2014 Ford Fusion and other 2013-2015 vehicles for this exact problem of a lack of coolant circulation causing an engine to overheat resulting in a crack in the cylinder head. In these models dealers were installing a coolant level sensor with supporting hardware and software at not charge to customer. Ford dealer is charging me $5,000 for short block replacement, which I feel is a defect of the Ford engine design. I purchased by car in Nov. 2014 so it only makes sense that this engine had the 2014 design problem. I declined repairs at that moment, to investigate the problem and asked for my car. The dealer stated they had to put my car back together so it would be about 20 mins. When I got the car back it seems to be running normal like when I took it in, but down the road about 3 miles the car started to sputter and stalled. After sitting a few minutes with flasher on in traffic on a major road, the car would start up and wouldn't go over 15 mph and continued to stall. I called dealer and they gave me the number to the towing company they use. The car was towed back to dealership. The Ford dealer is charing me $5,000 for short block replacement. They did file a complaint with Ford motor CO. Customer relationship center and they stated the dealer had opened a case by no programs in place for assistance.

The contact owns a 2015 Ford Fusion. The contact stated that while at stop, the vehicle would independently shift into neutral without warning. The contact had to restart the vehicle in to resume normal driving functionality. The contact had linked the failure to a defective powertrain control module (pcm). The contact had notified a dealer of the failure and was informed that there would be a three week wait for an appointment to have the vehicle diagnosed. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 70,000.
