I have a 2016 new FiST and I have this issue as well. It is very annoying. I don't know if it is related to the alarm, I have the KARR alarm system installed from the dealer and it is very sensitive. The car alarm goes off at least a few times per week when other people with really loud car exhaust drive by. Does nobody have a solution for this?
I found pulling the battery for about 30 seconds fixed it for me. In about 700 miles since, only came back once and went away on its own.
