Prado 120 Dashboard Cracks

Further to the bullbar question is the concern being expressed about the cracks in the dash of 120 Prado's built from 2003 to about 2006.
Some individuals have been getting them fixed under an Out Of Warranty claim plus $300 payment.
Many of not most have cracks across the passenger air bag container with a suspected danger from flying plastic debris when it is activated.
With no publicity or a factory recall, how many vehicles will be repaired? With the consequent drop in resale value not to mention the danger.
Some people have said that a crack in the air bag zone could be a roadworthy concern.
How do we get Toyota to make a move on this and similar problems?
