From what I can glean from the 'net it would appear that humidity/corrosion is the culprit over many years. Corrodes metal components of the airbags.
My missus has a 2012 Nissan Navara D22 2.5TD. She/we have been PESTERED by Nissan of late to take the car in to the supplying dealer for "airbag replacement".
Phone calls/emails/direct mail incessantly. So I book the car in , make arrangements to swap work shifts etc etc , real pain in the arse actually.
So I rocks up on the appointed day roughly 3 weeks ago , to be told "we are ripping the dash apart to replace JUST THE PASSENGER airbag."
The driver one will be recalled later WTF ? So 2 journeys/ 2 times pain in the arse and the dash opened up TWICE ? Can you imagine the dash rattles after that lot ?
So the bold me says " Are ye fuck" and I drive away from the workshop.
Today we get a registered post letter from Nissan and I refuse delivery from the postie ( nice guy). He says " I'm seeing a lot of this folks are well pissed off about it"
Perth WA has extremely low humidity and there has/have been no airbag problems here apparently. NT and Sydney , both older cars 2002/2003.
I think it's all part hype meself...
It is indeed a hassle and an inconvenience. doubled in this case ! If the airbags are fugged they are both fugged why not both being replaced at the same time ?
I worked for GM for 15 years , and have quite some experience with Hyundai and Daihatsu as well so I understand car makers and dealers.
Personal experience of many manufacturer recalls over the years. For absolute fact many cars have had the exact same aged "new" airbags installed into them !
I repeat the local area humidity is a major cause of "the problem" , and that is not a problem in Perth WA.
There is no doubt that I am at far more personal risk every time I ride my Harley than I ever will be driving this 2012 Navara.
Once Nissan Australia can do both airbags at the same time they can disembowel the dashboard ONCE only.
