I was surprised that the airbags don’t deploy if the engine somehow is shut off. I thought they deployed on impact. That sounds like something drivers should know.
Back when I worked for a company that made interior Cadillac door skins we had some 60,000 doors come back to replace studs inside the doors.
Seems that the studs were too long and snagged the air bags when they deployed.

I will bet that is by design. The sensors certainly would consume SOME power; and the risk of the bags going off accidentally while parked/engine off might be greater than having the capability of having airbags go off while parked with the engine off (having an airbag go off while you are not entirely in the car seat can definitely kill you). The only people who might be in this sort of situation would be in police cars, and they always keep the engines running anyway.
