I would push for no cost replacement under the consumer laws in Australia.
It should be covered under "reasonable durability" under the Australian consumer law.
The following was the extract from the "AutoExpert.com.au" web site:
"THE BASICS: YOUR RIGHTS AND REASONABLE DURABILITY
It is illegal for a dealer to brush you off onto the manufacturer. They are specifically not allowed to fob you off in this way. Holden should take urgent action to educate its arsehole dealer network, in my view. Especially as Holden is under the ACCC’s microscope following its own illegal consumer conduct.
There is a legislated consumer guarantee for
Reasonable Durability under Australian Consumer Law. This means that, regardless of the warranty status, goods and services are required to meet the durability expectations of a reasonable consumer.
I’m no lawyer but I am certain a reasonable person would expect a properly maintained car to last more than 49,000 kilometres. So it seems to me there are excellent grounds for a successful claim here."
