the truck has been acting up for several months now. it has been throwing out strange codes when attempting to start {parking brake malfunction, oil light, power train system default, ect} and often times it WILL NOT CRANK unless we hook it up to a battery charger for just a bit of time. The truck has a new battery that was installed by autozone, where it was bought {6 months ago}. Since we were in town, we stopped by autozone to get them to attach the code reader. {power train system and ABS malfunction} while driving, later in the day, the trucks auto start/stop system turns itself on and stops the truck dead in its spot.(danger: we were pulling onto the road {fm 2100} during rush hour traffic, when the trucks system went haywire and stopped us dead in our tracks in the center of both turn lanes and two of the main lanes.) there was no restarting, nor were we able to get the gear to change into neutral in order for us to be able to move it out of the main roadway. when we were finally able to move it, we hooked a fully charged jump box {one rated for up to semi truck sized vehicles} to it to get it started, and it simply would not crank for quite a while. at this time, we took the opportunity to recheck the oil level, which was set at full. After several minutes of begging "the truck" to just start so we could just take her home, it finally cranked up and home is where we took her. the truck has 19771 original miles on it. it was drove off of the show room floor, back in 2015, with 6 miles on it, and has had absolute regular maintenance and has only had one owner.

Auto start/stop causing wrench to come up. Seems like transmission has issue keeping proper fuel level to restart at red lights. Causes a hard start. Also driver door does not lock and unlock with the other 3 doors.

Truck shudders as transmission torque converter clutch attempts to lock up in third and fifth gear at light throttle position when shifting upward. This vehicle has the 2.7l engine with the auto stop/start feature. With this feature disabled the engine attempts to stall after stopping as if the feature is trying to override the off switch. After coming to a rolling stop and then trying to accelerate into traffic the engine will bog down and then a split second later feel as if it is going to full throttle without me depressing the throttle further. The engine speed surges when attempting to lightly accelerate and maintain speed with the flow of traffic. -ford needs to give owners the option to turn off the auto stop/start permanently. I was not informed this feature could not be removed when I purchased this vehicle. The dealer attempted to shut it off and only succeeded in disabling the remote start feature. I will never buy another vehicle with the auto stop/start annoyance.

This vehicle has the 'stop/start feature;' which actually shuts off the engine when at a stop and is supposed to 'restart' when the gas pedal is depressed; the 'electrical systems' are supposed to be operative; how power brakes are 'electrically operated' is beyond my comprehension; however, a few days after purchase I was at a stop lite when the engine shut off, and eventually re-started' by itself; the dealer sales staff never informed me of this 'feature,' and also did not tell me there was an 'override switch on the dash; the fact that I did not override it, and that the engine did not restart when the gas pedal was depressed, to me means that this 'feature' is, on this vehicle, inoperative, and therefore inherently dangerous and life threatening; my wife refuses to drive it, and it was towed in to the dealer on 12/21/15, where it remains; I refuse to drive it as well; lastly, the vehicle exhibited no 'stop/start feature' upon a pre-purchase test drive with the salesman in which we made numerous 'stops' and a friend of mine was with me on that test drive, who will attest to this fact; likewise, it did not have any 'problems' until almost three weeks later, during which time I drove the vehicle daily.
