I purchased my f-150 ecoboost, on july 28, 2012. Almost immediately after purchasing it, i have had issues with the engine.

The engine boggs down, to an idle. The truck has left me stranded numerous times. I took my family on a…

While driving on an interstate with two motorcycles in the bed of the trucks, the truck started to shake and vibrate. Have since seen this referred to as the shudder that sometimes precedes the limp mode which results in power failure. After changing lanes and monitoring tires on nearby vehicles in motion we confirmed it was not the road. I have since experienced it again but cannot recreate the behavior on demand…

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…
