The rollover protection headrest will deploy sitting still!!! Sometimes after cornering they will deploy. Today, I parked at the credit union and about 2-3 minutes AFTER stopping (normal, smooth stop from 25 mph!!), they deployed! Last year after having been in storage, the dealer charged the battery and I had no more problems. Got NO idea why that matters...the car starts, runs, fine, no apparent low battery indications like blower slowing down when turning headlights on, etc! Weird!
Mine is a 2005.
My local gas station mechanic can fix this... especially when the top is already down. He simply inserts a long screw driver next to the rear headrests and hits a release that lets each headrest go back down, ready for the next time.
