I’ve got the same random stalling issue with my 2013 Focus ST. My car is completely stock and I don’t push it hard. I drive with both 87 octane (for long hwy trips) and 93 octane (all other times), and never had an issue up until now. I’m 55 and have been driving a stick for 40 years, so it’s not me.
3 weeks ago, after 1 year of ownership and ~10,000 miles and 1,000 miles from home (I was visiting NC, I live in VT), the car started randomly stalling when coming to a complete stop at a light or stop sign. But not always. Sometimes it will stall over and over 5 or 6 times, and then will behave perfectly for the next couple of days. Most of the time (like when I took it to the Heritage Ford dealer on July 3 to fix the problem) it behaves perfectly.
Other times the rpms will drop almost to zero, then the engine will catch itself and the rpms will fluctuate between 5k and 15k for a few seconds, and then settle down again. Other times the rpms drop completely to zero and the car needs to be restarted. I was almost broadsided two weeks ago because I was not aware that the car had stalled, and I was rolling into traffic. This stalling has happened at least 50 times in the past month. NOT ACCEPTABLE.
Most of the time, when it stalls, there is no engine warning notice. 3 times out of the probable 50 incidents the car told me “Engine Fault Service Now”, and the message disappears when I restart the car. Other times the car will tell me, "hill assist not available, service soon”. The Hill assist comes and goes randomly, just like the stalling. On one occasion the car was running awful for about 10 minutes: rough idle, sputtering and jerking like it had arcing wires or bad gas. I shut it off, restarted it, and it ran fine for the rest of the trip. These things are completely random and very frustrating.
Long story short, I took it to the dealer, and the car behaved perfectly for them. They said they cannot service a problem that they cannot observe. Now I have it home and it’s stalling on me. So what can an ST owner do?
Hey guys. FWIW I continued experiencing the CEL and lack of power/stalling issue. It was ridiculous.
I finally took it to the Better Business Bureau for arbitration and was awarded a replacement.
Let's just hope the next one behaves..
Wow ...good for you.

Hey guys...I'm another victim of this stalling issue. Just curious to know if the 02 sensor replacement is still doing the trick. I've a '13 ST2 with 80k on it.
I've been to the dealer 5 times over the past 18 months or so for this. The first time my local dealer said it was an outdated control module (PCM) so the flashed it. That lasted about a week. Then in the middle of all that, my gas tank collapsed - dealer said they were seeing a few of these issues coming in due to defective tanks produced by Ford's vendor - that was fixed and dandy now. I've had all the advisories and recalls done on it (including the wire splice recall). Last November, it got really bad so I took it back and 4 days later, they said it was fixed - bad electronics on the throttle body so the replaced it. It stalled 5 miles from the dealer the day I picked it up.
Two weeks ago, I decided to take it to the dealer that I bought it from. They still cannot reproduce the issue. I told them not to call me until it's fixed. I've offered them twice to go down and take the car for a 30 minute drive with their tech and any gadgets they need to hookup to take readings. I know the car has to run for 20-30 minutes before it misbehaves. They still haven't called me back.
Another ongoing issue is corrosion on the negative terminal - since day 1. I've replaced the battery once with Motorcraft and now with Odyssey. The first dealer keeps telling me my battery's are all bad. Yea right. I'm guessing there's some short somewhere and it could be related to the stalling but the o2 sensor makes sense too given that it takes 20 or so minutes to reproduce.
My ESP plan has paid for itself. It's what I get for buying a car the first year it hits the states.
I can do it cheap, fast or right. Pick two.
Update...tried twice for over 30 minutes each drive to reproduce the issue at dealer. Never happened.
They did reprogram the body control module due to an advisory and cleaned the negative terminal of corrosion (which I've done in the past) but i'm not convinced these were the cause.
UPDATE: BCM update appears to have resolved this. There is a recall labeled 16C13B (or without the B).
