I was driving our 2020 Ascent and the SRS Air Bag red light came on in the center display. Called the dealer and the earliest appointment I could make was for a week from today. If it is the sensor like you mentioned, I assume I should not drive it.
Maybe stop by the dealer or even some auto parts stores can read the srs codes. That would give you a better idea if it’s safe to drive or not.
My e39 has had an airbag light on for about 6 months but I know the sensor that tripped it. Not a concern to me.
