NHTSA Complaint #11469750 — 2002 FORD F-150

1. Coils on top of spark plug get moisture in them when there is just the right kind of rain storm. This makes the coil or coils fail until the dry out. This seems to make the coil eventually go bad. Yes, it is available for inspection. 2. Not sure if its a combination of heat and moisture but sometime right away and sometimes a few minutes into driving the coil or coils fail and the engine loses power. Then if seems to be a random, unpredictable occurrence until it dries out, Very Unsafe. If one coil fails it loses just a little power, but if more than one fails it loses a lot of power and stalls at times. This is why I am writing it up. A few time now, I have gone to pull into traffic and then I lose power and either have to run off the road or just upset the car behind me if they are not too close. 3 & 4. I have advise all the Ford dealerships in my area trying to find one that has a fix yet. The only fix Ford has, is a new designed coil, which does not appear to be any better. The dealership just replaces the coil. I have had all my coils replaced, some 2 or 3 times. 5. It depends, sometime the engine light will come on and advise which coil is misfiring and sometimes if does not. Right now my engine light is on and it displays the #6 coil misfire. Then the engine light will go out after it dries out and stops failing or it will stay off if the coil had gone bad again. I am sure its not just the F 150, but the 4.6 liter engine that is in other vehicles. I started keeping track in 2012. I wrote a letter to Ford in 2015 and they replied, there was no recall. I have several repair receipts and the letter from Ford if you need that. Just search on your site and you will see many complaints. One example Manufacturer Communication number: 041601. If you google "ford fix for moisture in coils" you will see many forums trying to figure out a fix and just complaining.
