Tl the contact owns a 2012 Ford F-150. While driving 75 mph in fog, the contact attempted to pass a tractor trailer. The vehicle hesitated, failed to accelerate, and decelerated to 60 mph. In addition, the check engine warning indicator illuminated, the rpms fluctuated between 2000-4000, and the gear shifted from fourth to sixth gear. The local dealer and manufacturer were not contacted. The failure mileage was 51,000.
I was traveling on a 4-lane, 65mph highway when I floored the gas pedal. The truck failed to accelerate as it should have. Instead, it acted as if it was coasting. There was no power for several seconds even when I moved the gas pedal to different positions. When the truck finally seemed to resume power, it started to shake violently. The shocked passenger and I looked at each other, then I checked to see if there were parts strewn on the road behind me. Suddenly, it smoothed out and there were no more issues on that trip. I had been driving that truck for about 10 hours with various forms of precipitation at the time. This was December 21, 2013. The second incident was on December 28, 2013. Weather conditions were sunny and dry. I had been driving about 50 minutes. I floored the gas pedal again to overtake a vehicle and was barely able to overtake due to no power. Again, I worked the throttle to no avail. The truck finally recovered but started shaking violently again. As before, it smoothed out. I took my truck to a local Ford dealership where they told me it was showing no codes and that their techs could not reproduce the symptoms I had mentioned. I checked on NHTSA website and found this issue is under investigation. I do not agree with the service bulletins. My theory is that there is a computer programming problem specific to this direct-injection, turbo gasoline engine. I plan on trading for something other than an ecoboost engine, as this problem is dangerous.
