What's wrong, in plain English

Mazda says the wiring harness on some CX-9 SUVs can disrupt electrical connections. This may stop the passenger-side front airbag from working, cause the turn signals to fail, or prevent the engine from starting. These are separate possible effects of the same wiring problem, not something you would notice unless one of them happens on your vehicle.
