is it or is it not dangerous?
I think you are more likely to be injured in the waiting room during the recall, than by a Takata airbag failure, but as it's a possible/forseeable/preventable event, they have to be replaced.
It's hot & humid conditions that
may have affected the chemical propellant where it's been mixed without a drying agent. When the airbag is triggered this
may cause an uneven production of gas resulting in bag inflation at a greater than designed rate or
may cause possible fracture of the chemical propellant capsule which has resulted in shrapnel injuries in a handful of people worldwide (over nearly two decades).
As the injuries stem from an airbag deployment the best course of action is not to crash, or keep your car in the tropics for many years.
