Wiring problems of the 2011 Ford Edge

Two weeks ago my Ford Edge limited (2011), which I had for less than 2 years and it had ~21000mi, started to have serious problems. While driving on one of the busiest highways in houston, the acceleration suddenly disappeared (gas pedal went limp) when I was going 65-70mph. The car still had power and I was able to break and steer to the emergency lane. While doing that, almost got hit from the back twice. After complete stop at emergency lane, I restarted the car. It started fine, and I was able to get home, though I was afraid to take a highway. Next day, same problem happened twice, and both times at about the same speed. These times, however, I felt strong vibrations when restarting the engine. All of the times, an orange wrench appeared on the dashboard indicating power train problems. After the second time, a light indicating that engine needs to be serviced soon also appeared. This light turned off on its own couple days later. I had plenty of problems with this car before. This was the last point when my patience with this car had ended. Besides, I could get into a serious accident. Luckily, all of the times I was driving after the rush hour and traffic was not too bad. Otherwise, I would be definitely be hit by someone. In any case, I brought the car to the dealership and traded it in. No wonder, I was told in the dealership that they are not aware of any problems like this and offered servicing the car. I refused it, because of multiple problems I had with this car before and just didn't want to keep it anymore. Ford definitely needs to recall 2011 Ford Edge with such problems. I will call them and complaint to them as well. For now, I would recommend people not to buy 2011 Ford Edge as it has so many issues, especially with electrical wiring/components and sync. This was the most expensive and most unreliable car I've ever had.
