Stuck in "Park"

Drove our 2015 Prius Four into the car wash today, somehow got it into "Park" instead of "Neutral," and had a difficult time getting it out of
Holding the shift lever to the left accomplished nothing, nor did powering off and on again. Couldn't get it into "D" or "R" either. I can't even tell you precisely what I did to get it out of "Park," unless it was leaving it powered off for longer than previously before powering it on again.
Is this a known problem?
