Default you need to scan your airbag control module to find the root cause...

but there is a known problem with the driver's side thorax bag (in seat). It has to do with a bad connector.

You can tweak the connectors. Dielectric grease and Zip-tie them tight.

Default I had that problem.(and fixed)

It was a bad seat beal pretensioner for one of the rear seats. When your 3rd passenger buckles in, the computer checks that seatbelt and you get an airbag light. They replaced the seatbelt tensioner under warranty.
