The other day when I parked the RX and turned off the engine, I heard a strange bump and all the windows and the moonroof opened! I closed them, and when I opened my door I got a warning message on the center display "Moonroof opened."

The message would persist every time I opened the door. Finally, I cycled the moonroof open and closed, and that seemed to take care of the problem.

Has anyone else experienced this? A software burp, I imagine, but I have nightmares of this happening in the middle of a rainstorm.

 

I presume there was no way you could have accidentally pressed and held the unlock button on your keyfob - perhaps something in your pocket jamming against it or whatever

 

^^ yes, it is very possible for you to have acitavted the ventilation function for hot days

 

Yes, that evidently was it. I tried it just now from outside the car. I keep the keyfob in my left pants pocket, and it must have pressed against the door. Thanks.
