When was the EcoBoost F-150 made? How many miles on the truck? The EcoBoost F150's produced from the original until January 2013 had a Technical Service Bulletin (TSB) for an Intercooler design issue (condensation formed and made the engine misfire or flat line. The truck computer will spit out a code for a misfire on cylinder #4.
Yes, we encountered the engine misfire when trying to pass a car while in a heavy rain. The truck accelerated to 3000 RPM's and started missing, took foot off throttle for a second and it recovered. No we were not towing the TT. It happened 4 times on our first 500 mile engine break-in. I thought Oh Crap, what did I decide to buy... We took the truck into the dealer upon returning home, the dealer put in on the computer and it showed cylinder #4 had misfired, and the engine code. After researching and calling Ford, they told us that there was a TSB to replace the Intercooler. Called the dealer, he just received the first ones and they replaced it. Since then, no engine problems.
This only seems to happen in high humidity areas (Florida). I believe that they started installing the new redesigned intercoolers in January of 2013.
Not everyone encountered this problem, but if you do and the intercooler has not been replaced FORD will replace it.
So, would I purchase a 2012, knowing that there may be a slight chance of this happening, YES, I would!!! as I know FORD will take care of the problem (TSB)
As far as the trans shifting up and down problems, not a single issue and we have put on 45K so far. We love the way it goes through the gears both up shifting and down shifting. There were some complaints (Ford F150 forum) of towing with gear ratios not intended for towing (other than the 3:73 or 4:11) where the trans would constantly up and down shift when small inclines were encountered on the highways.
No carbon buildup issues...
So after all of this, you ask, would I do it again... you bet I would... love blowing the doors off of other TV's towing up the mountains, smokin' the tires at the stop lights, and still getting over 20+mpg on the highways (without TT), and this is on the 157" frame with the LT tires. Heck my '69 Old's W30 442 only got 5mpg going downhill with a strong wind behind me.
Do your home work to see if the 2012 will be a good fit for your TT.
Are you purchasing from a dealer or is it a private seller?
What I would recommend is get the VIN and see if all the TSB's have been cared for. Check car fax for any accidents. You can check at the Ford dealer to see what maintenance has been done there.
