I had two related problems
I had two related problems with my 2020 CRV: the car locking itself randomly, often overnight, in my garage; and all four windows opening by themselves. Fortunately, Avalon Honda has a great service manager who does not see it as his mission to blame the customer or save Honda money. To the contrary, he took the problem seriously, put the car through two diagnostics, could not find a problem, so he replaced the car's computer for free (I was within the warranty period).
