Must have been accidentally triggered by the remote button inside my pocket. I tried it again this evening and it is back to normal. Just odd that it happened 3 times in succession, with me getting in and out of the car each time (and an extra time to get out and shut the charging door), and it still triggered in the same fashion. Two and half years of driving it daily and it didn't ever happen until today x3. Odd luck.
I did investigate the manual trigger and my foot doesn't come close to triggering it and I'm sure I would have felt it anyway.
