First time this has happened. Drove into my garage. Tried to insert charger and found the locking pin was still lowered so couldn't put the charger plug in. Car was unlocked. Charger door unlocked obviously. Had to lock/unlock multiple times, unlock button twice a couple times...finally it retracted. Seems to have sorted itself out. Mechanical malfunction or transient electrical/software thing like screens not booting up? Maybe I should lubricate the locking pin area - first time I've seen the mechanism - I guess normally it wouldn't be visible.
