F-150

  • 2,000 miles
After using cruise control for 1 hour on a 4 lane highway at 70 mph during high humidity early in the morning I try to accelerate and the motor loses all power. I had tsb 12-6-4 applied to the vehicle Friday, three days ago, and though it may reduce the likelihood of this situation, it does not overcome what appears to be a design flaw with the intercooler in this ecoboost motor. This flaw allows for condensated water to be sucked into the motor and causing the misfire during hard accelerations after long periods of using cruise control in high humidity situation. The impact of losing power will be a fatal accident for a customer at some point in time if it has not already occurred.

F-150 6-cyl

  • 800 miles
While driving a brand new 2012 Ford F-150 w/ 3.5L V6 eco-boost I was attempting to merge onto interstate while towing a small boat trailer when I lost towing power (RPM dropped instantly from ~4000 to ~2000 RPM despite having accelerator depressed) and the entire truck started violently shaking. This continued until I completely let off the gas for a few seconds. I then pressed down on the accelerator and things were back to normal. I could have easily lost control during the rapid deceleration had the roads been wet or if a big ole 18-wheeler had been behind me things could have ended poorly.

F-150 6-cyl

I was driving in a light rain when I gently pressed the accelerator and the engine started vibrating excessively making the whole truck vibrate like the wheels were falling off. The incident lasted about 10 seconds before it returned to acting normally.

F-150 6-cyl

  • 2,200 miles
While merging into traffic and accelerating, the engine stalled and the truck engine almost died. This has happened numerous times since, mainly when I accelerate quickly as in trying to pass a car. It could easily get someone killed. The dealer cannot duplicate the problem or come up with a fix because there are no codes showing even though the check engine light comes on when this happens I have checked the F150forum.com and its evident that this problem is rampant with this engine..
