Traveling home at 35mph, vehicle lurched and lost power - was able to drive 15 mph max speed the 3 miles home, but vehicle barely accelerated after slowing or stopping. Power train light and airbag light came on. As vehicle driven into garage, dashboard lighting went off suddenly, but vehicle accelerated with effort into garage. Four hours later at 10pm, started vehicle, no warning lights came on dash. Morning of December 10, called dealership. They advised if the light did not come on this morning, then they would not be able to diagnose problem. Vehicle drove normally to work with no warning lights. Dealership said there was low voltage on the accelerator causing problem and they ordered parts and "fixed" it on December 18th, but on December 24th, I was on interstate at 55 mph, vehicle on cruise control. Speed limit increased to 60mph, began adjusting cruise control speed via thumb button on steering wheel column. After three thumb "clicks" to 58mph, vehicle lurched and lost power and began immediately decelerating. Power train light and airbag light came on. Pulled to right berm and shut off engine. Over the next 37 minutes, attempted to start vehicle every 5-6 minutes. On six different attempts, the vehicle revved as accelerator applied but the engine never "caught" or turned over, it would die as soon as the accelerator pedal released. On 7th attempt, the vehicle turned over, and I was able to proceed to the next exit. Since the car seemed to be running normally, I risked it and tried to get the vehicle home, knowing that a tow at 8pm on christmas eve would be expensive and timely. The power train light and airbag light remained on for the 8 mile trip home. The next day, vehicle operated "normally" with no power train light or airbag light. Second occurrence.

I drive a 2013 Ford Fusion, which I purchased new from an authorized Ford dealership. By 3772 miles, the car began to downshift violently, upshift around 6 or 7 thousand rpms, not shift at all, the heated seat would come on by themselves with no indicator lights, the transmission gear indicator light stays on when the car is off and no key inside, the radio turns on and off at will when the car is parked and locked up, a severe odor of mildew comes from the A/C when first comes on, the trim molding keeps coming off, the car has lost a significant amount of power, the led lights in the tail lights stay on all night even after the car is turned off, and etc. These problems are inconsistent in nature with no identifiable conditions causing the series of non-conformities. Ford Motor Company hasn't been able to fix the car after numerous attempts. I am currently in arbitration.

I was driving to an appointment, and ran late because of the failure. I stopped at a stoplight, and tried to take off, but then the car went into "limp home" mode. I hobbled the car across the intersection, and then began to use my obd II code reader that I purchased for a different vehicle, and read the code. It was P2011, and cleared it the car ran fine for a while, but the problem was still there. I went to the Ford dealership the next day, purchased the new "updated" throttle body. I got it over to my uncle's shop, were I replaced the old throttle body with the new one. I have been driving with the new throttle body, and have not had any problems since.

While driving on a city road with my foot on the gas at 35-40mph, the transmission erratically shifted into a lower gear on the transmission, causing the engine rpms to near instantaneously to go from 1750-2000rpms to just over 4000rpms. Through the RPM increase the vehicle maintained the previous 35-40mph speed. Ultimately, was forced to brake to bring the engine rpms down.
