My XC60 regularly unlocks and send the “Your Volvo is unlocked” message.
I have locked using the remote/key and using touch on the door handle.
It happens in my underground garage and équido in open parking lots.
Any ideas?

 

Same with my 2020. No real ideas unfortunately… Best guess is either a SW/HW interface bug or literal bug (some critter walks under the handle in the right spot and the sensor picks it up for some reason). My account does not seem to be compromised.
