I have a 2012 ford f-150 with the ecoboost engine. While slowly accelerating at higher speeds (generally around 50 to 70 mph), the engine misses terribly on multiple cylinders and the truck jerks and lunges violently all while losing power and speed. It happens frequently, but most often when slowly accelerating to maintain speed up a hill or pass another vehicle. The loss of power is extremely dangerous, especially…

In heavy rain conditions after driving for 2 hours in the pacific northwest here in the state of washington, the truck ecoboost turbo stalled and lost power during an acceleration onto a freeway on ramp. Intermittent check engine light and partial limp mode occurred. Dealer misdiagnosed the problem as a loose connection when in fact it was the known stall/shudder issue that multiple ecoboost motors on f150s are…

This happened two more times during the trip. The second time the check engine light began to…

However at about 11,500 miles driving in a rainy humid day on the highway i got in a spot where i had a rig going about 30mph and i was doing about 60mph having more than enough time to pass safely before the other rig coming up in the passing lane i decided to go around.. As soon as i pushed the pedal to the floor and got…

Noticeable lag during acceleration. Most noteworthy incident involved passing at freeway speeds, engine bogged down and car felt like it was about to stall. Have noticed this a few times since as well. We are in monsoon season, have had rain and higher than normal humidity. Have also noticed what feels like delayed and hard transmission shifting. Fuel consumption/mileage seems to be affected. (was getting 17-23mpg…

I was merging onto an interstate, accelerating from 20 mph to 65 mph to blend in with heavy traffic. The engine began to spit, sputter and shake and bogged down and wouldn't exceed 50mph. With a tractor trailer coming i had no other choice but to abort my merge and pull to the side of the road. I then waited for all traffic to subside before i made another attempt to pull onto the highway. I took the truck back to…
