Several times now. while driving the car (ac normally on), we will get to a full stop from driving (over ~40 min trips)... whether in traffic on a freeway or stop sign... the cars check brake system light will flash & beep, and the car will not accelerate. neither the electric motor nor the gas/hybrid engine will engage and drive. turning off and on the car does not reset it... it takes repeat effort and several minutes (once over 10 minutes) to be able to start up. can't imagine if it were to happen on a freeway again with a child or my other half in the car! scary! took it to the dealership several times without any luck diagnosing or fixing the issue... we need a reliable vehicle this is insane. now the car is out of warranty and doing it again. ford nor any dealer shop can help fix this. they can't reproduce it, the issue is sporadic which makes it worse & more terrifying to experience. so far 4 occurrences within the last 4 months. about 10 + over the 3 years since we purchased the car new. the lights always reset by the time we make it to a dealer lot. their systems cannot trouble shoot anything at that point! it happened again recently when parked for over an hour, after a 80 mile drive. when we went to drive home, it would not drive/accelerate. same brake system light issue was popping up again. almost had to get a tow, then all of a sudden it started back up again as the driver got to us.
While driving down a city street my car had a complete loss of power, with multiple warning lights and alarms going off. there was no warning of this failure prior as the car was operating normally. associated with this loss of power was a loss of steering and a loss of power assist braking, which resulted in the car came to a stop in the middle of the street. once in park it would not allow changing gears. a tow truck required the use of tire dolly's to load the vehicle, which was taken to the dealer for diagnosis. the dealer maintenance department was unable to diagnose a cause, and used the analogy that the car had an "electrical seizure," which i interpret as a catastrophic electrical system failure. they were able to make the car operable by rebooting, and reinstalling software, to the car's computer. *tr
