So today my moms car when making a left turn to turn from one street onto another it just shut off. No stumble just off. So we had a few minutes before my doctors appointment so we drove around and when turning left into the parking lot at the doctors it died again. Then in the way home the idle when sitting would surge a little. Finally it through a pending code p0300. So I looked over everything obvious. There's no vacuum leaks spark plugs are 6 months old she always get gas at the same bp station. The throttle body had very little carbon as well. I know some of the older focuses had fuel pump issues not sure if this year still does. I can't easily check fuel pressure as there is no shrader valve so I haven't gotten a chance to do that yet. But when it's fine it's fine . She drove it about 10 miles home and said it never acted up. Any thoughts? Or anything in general I should check?

I don't think it's electric assist. It's when turning left while driving. If it's parked it doesn't affect it to turn. As far as what could get touched or shorted I didn't observe anything out of place or that could be a problem. It did surge and run rough while sitting at my house but when she drove home she said it did fine.

Try cleaning the throttle body. I dont know if its related, but the Mazda 3s with the smaller engine around this time had issue with random shut downs.

Heavy key chain? Have seen this MANY times. Weight of the keychain is enough to shut off the car.

Isn't there some sort of sensor that increases idle when steering, so that it doesn't stall? Can't think of the name.

Po300 is misfires. Start looking for a wire touching or vacuum hose leak opening when the engine is moved by turning.

There is on some cars Im not sure about this one. But it was surging in park in the driveway and running rough . When the pending code came up on the scanner the live data showed short term fuel trim at +25

Look around closer for vacuum leak, loose connections, etc. Check every hose, don't assume if its connected its okay.
