While driving down the highway, vehicle will go into "limp" mode. Power reduces on vehicle and will not allow to maintain highway speeds. This has happened many times during a trip especially in humid and cold conditions. The scariest situation has been while towing a trailer. Truck went into the reduced power limp mode and was almost run into by a semi truck. I have had the truck into the dealership several times…

While traveling at highway speed (cold winter morning), with cruise control on, started to climb hill, engine began to throttle up, then the truck began to shake violently, engine lost power. Shut off cruise control and coasted onto shoulder. Was able to slowly engage throttle and continue, but any increase in throttle above "gentle" would bring on the shudder and power loss. Engine light flashed and stayed lit for…

This write up is for a 2012 ford f-150 truck with the 3.5l ecoboost v-6 installed. Jan, 2013-while driving on i-24e, i was pulling out from the rest stop, just north west of exit 1. I went to pass a 18 wheeler and my truck came "unglued". It practically died in the passing lane when i pressed the gas peddle. It shuddered so hard; i didn't think i would be able to get off of the road before it died. It was missing…

The truck started shaking violently while trying to pass a truck on the two lane highway. There was a huge loss in power and couldn't complete passing the truck. Extremely unsafe to have to slow down while still shaking and bucking to get back behind the truck that i was trying to pass. This violent shaking and loss of power has happened many times even after the many trips to the ford service department's. None of…

While entering the highway from the ramp i pulled into the first lane and tried to accelerate. The truck started to miss and buck and would not increase in speed causing me to pull off the roadway. I shut the truck off and restarted it. The truck will only run if you accelerate very slowly. Any attempt to gain speed is met with the same response. I took the vehicle to the ford dealer where they cleared the codes and…

While driving at highway speeds, after accelerating to pass another vehicle, the truck suddenly shuddered and there was significant power loss. So much so, it was dangerous to get over to the side of the road to see what was wrong. The vehicle continued acting like this throughout the day. I took it into a ford dealership who 'resolved' the issue. 1.5 years layer, the same exact thing started occurring again…
