I have a 2012 Fusion 2.5l. About 3 years ago I have had this problem with it that once stopped, say at a stop sign, it really hesitates and lurches upon resuming travel. Periodically when slowing down, such as making a turn or in stop and go traffic, the car will just quit. It starts right back up like nothing is wrong. Never get a check engine light or any code to go along with this behavior. Throttle body was the first thing that was replaced but the problem never stopped. PCM replacement was suggested next by my dealer and that was changed out. The problem still persists and the only solution that I'm given is replace the PCM again, a mere month after it was replaced. Other shops are just at a loss as the Ford service center is. The other odd thing about this is that it is an April through Oct problem. In winter my car runs great, no hesitation, no suddenly dying while slowing down. Now that it is April it quit already turning into work.
While service dept has been able to duplicate the problem, they have never found anything wrong. Has anyone else had similar problems or come up with solutions to this?
I'm frustrated too that this problem started under warranty but I am not outside of the warranty even though the issue was never resolved.
