severe misfiring from one or more ignition coils

A PCM failure leads to melt down (literally) of one or more ignition coils. Essentially the car computer can fail and overcharge the coils causing them to melt and fail.

I started my car up one day to a severe misfiring that was causing the entire engine and car to shake. After I limped it over to Autozone, they came back with a few codes indicating two of my ignition coils were having a malfunction. They were P0351 and P0354, ignition coil A and D respectively; however, this issue can cause any and all of your ignition coils to fail so if you are experiencing this problem you may get any codes between P0351 and P0356. After replacing the gasket on my valve rear valve cover as well as the ignition coil (A) that had melted, I started the car to find the problem had returned within a short period of time. I took out the less than 24 hour old ignition coil to find it too had melted (pictured).

NGK Technical Training on YouTube has a great video explaining this problem and how to repair it (search 'Ford's Fusion/Escape 3.0L Misfire Diag & Repair! What Killed The PCM? P0300-P0306': https://youtu.be/ypp_P9GeeIw

This is a known issue common among Fusions between years 2006 and 2009 that my local Ford was aware of.

The repair requires replacement of your PCM, all six ignition coils, and all six spark plugs for good measure. This can cost well into the thousands of dollars in repairs and labor including the cost of reprogramming a new computer to work with your current keys.

CircuitBoardMedics (google them) provide a service to repair your current PCM for ~$300 which won't require a reprogramming. I haven't gone this route (yet) so I cannot tell you how reliable this is but I've seen testimonies on forums saying that it is legit.

Some people have reported that their emissions warranty (up to 80k miles) covered the full repair of this issue. I'm just about to pass my 100k miles mark.
