Transmission shifts erratically, jumping from lower to higher gears. While up to speed, immediately shifts to 1st causing redlining of rpms. Speedometer jumps erratically. Happened initially while accelerating from a stop. Caused loss of power and feeling of misfiring, then sudden surge forward. After getting up to approx. 40 MPH, transmission shifts to 1st and stays there. Could have easily caused a crash if this happened while cruising at highway speeds.

When attempting to accelerate from a complete stop the truck will only move forward when the pedal is fully depressed. When this is happening the truck barely moves then it will catch and lunge forward at break-neck speed. This same thing happens at approximately 30 MPH, will be accelerating normally when all the sudden the RPM and speed gauges completely drop the engine losses all power and if the pedal is continued to be pressed the truck will lunge forward, again at break-neck speed. In a 10 mile trip it can happen 3 or 4 times. Today we had a new experience where when decelerating to come to a complete stop the motor began revving to redline all while only the brake was depressed. On green light the acceleration again was limited to full petal and a limp till burst mode. These events all scare the family to the point of not riding in the vehicle.

Having issues with the ecoboost accelerating upon take off or getting on to road ways numerous times I have come close to getting hit because of no power upon accelerating now this has been going since purchase new with only 116 miles and purchase date 3-17-2013. The dealer says this is normal operating condition for the vehicle to have lag time before power.my feeling is if you are sitting at a light and you give the vehicle gas the vehicle will move slow and then do a sudden acceleration and could cause death or injury to someone unsafe truck. Now I'm having issues with the driver window not going down or when it is down will not go up they say this is normal operating procedure ford has some issue and they need to be corrected before someone gets killed or hurt bad.

2012 ford f150xl with 3.5l v6 ecoboost engine. Accelerating to merge onto highway with cruise control off and after successfully merging, vehicle expectantly lunged forward while foot was off gas. Engine kept accelerating for period of 5 seconds reaching 90mph. I was hitting the brake the entire time with no effect until heard a dull clunk or pop sound coming from the engine compartment and behind the steering wheel. After this sound, the engine stopped accelerating and I was able to regain control. If there was a motorcycle or car in front of me I would have run them over.
