I was joining the highway and went to accelerate and my truck fell on its face, slowed to 20kms and I had to pull on the shoulder to avoid being hit from the rear by a transport truck. After months on waiting for parts, Ford replaced the CAC and reprogrammed my truck, Now it is wait and see if it does it again.

Update from Jun 22, 2013: Had the E.C.U. reflashed because the truck had a shudder/vibration under hard acceleration after the C.A.C. replacement and reflash. Dealer says it is a new calibration so I will try it and see if it improved any thing, also the dealer said it may be a slight detune/lower horse power. From what the dealer says is that the Eco-Boost fusions do not have the same problem because the C.A.C. is closer to the heat of the engine, there for less efficient at cooling the compressed air from the turbo so less condensation. What they are saying is that it is water that condenses in the C.A.C. being sucked into the engine causing a misfire.

This problem occured four times in two consecutive days early August 2012. The temperature was very hot and the humidity was high. I had been driving for about six hours. On two occasions accelerating to merge to the interstate and two other occasions changing lanes to pass another vehicle the motor almost stalled. Some complaints refer to that as limp mode. I was lucky as oncoming vehicles used their brakes to avoid a collision otherwise my vehicle would have been struck in the rear. My reaction was to put the pedal to the metal but it seemed to make it worse. The solution was to let-up on the gas and accelerate slowly to to a proper speed.

Ford new about this problem. They issued a service bulletin TSB 12-6-4 dated June 7, 2012 with a solution but they never notified me or issued a recall about this dangerous situation. My near collisions happened almost two months later.
