On 29 may, 2013 my family and I were driving on the highway when the car stalled. The rpms went up and the car just kept losing speed until it would no longer go with no trouble lights, which it gave the impression the car had slipped into neutral. A tow truck came and brought the car to the nearest Ford dealership. The dealership service representative started the car as soon as it arrived and it started up right away and stated since there were no trouble lights that they could not properly diagnose the car so they returned the car to us. On 5 June, 2013 my family and I were driving on the highway when it stalled again, but we turned off the car and let it sit, then restarted it and it was able to make it to another Ford dealership where they did an inspection. They drove the vehicle for 27 miles and could not recreate the issue and no trouble codes were present so they could not diagnose it. They gave us back our car and on our way home it stalled four more times nearly causing accidents with a semi-truck. It was brought back to the first Ford dealership where it was kept from the 7th-11th. The problem could not be created and the car was released back. On the way home it stalled again. On the 14th it stalled again while waiting at the right turn lane at an intersection and I brought it to the dealership where it was kept from the 14th-19th for further diagnosis. They were finally able to get a code that required the powertrain control module (pcm) to be updated and recalibrated. On the 20th it would not start and a tow truck was called and they gave it a jump start. I then took it to auto zone and the battery tested fine and the dealership later had the same results. A pen light tester showed power was being drained from the battery. The car stalled again on the 22nd requiring it to be pushed off the road twice. Now the dealership says the battery is bad. Recall?.
