i had this same issue, about a month and a half into my purchase for my 2013 titanium. It occurred approximately every two weeks, and most often as i was in my own driveway! After getting an oil change and having them look into it, they couldn't find anything. They placed a call/ticket with Ford, and no resolution. I still get the error occasionally, maybe every 6 weeks or so? it seems to be related to when my vehicle is dirty, or if there is a wind or rain...i suspect it sends a false read to the sensor. i now have about 25,000 km on my vehicle and no issues.
