I have the same problem. This started back in February for me.

sometimes it is the "handicap man" other times the passenger sensor is off with no one in the passenger seat.

There is a Technical Service Bulletin out there for this issue, but when I took it to the dealer for inspection I informed them of this and wanted it taken care of. They did "$90 worth of checking" before calling to say that my car didn't fall under this Technical Service and it would involve taking apart the entire console to check.

I said eff that, Ill wait until I decide to get an AC unit for it.

I do have a theory though: Does anyone with this problem have the Aveo 5 SVM or an aftermarket radio?
