Also, right when this happen the passenger air bag off light came on, it stays on for about 1 min also and goes off when the dinging stopped, yet the dash light stayed on.
My guess, it is the sensor that detects if weight of the passenger is enough to use the air bag is malfunctioning due to the heat in the seat.
It never errors unless the heated seat is on. I have not used my heated seat yet to find out if it happens to the drivers side.
Does anyone know how much weight I need to put in the seat to trigger the airbag so I can confirm the issue with out having to make someone suffer a heated seat in the summer?

Funny you bring this up. Here in PHX when the temp rises above 110, even touching the seat with your hand will trigger the seat belt chime in my car. I have a habit of having my finger touch the seat while driving with one hand and lo and behold the seat belt warning starts chiming though no passenger is in the seat! Definitely a combo of heat and some sensor not agreeing. BTW, I also have heated seats..
