Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
The reason why dealers don't readily offer these updates is because they usually cost the dealer money. With warranty claims Holden will pay the dealer for like 15 or 20 minutes for a job that takes 40 minutes plus.
They also won't pay for warranty unless the explanation of the complaint is within guidelines, this is why they're saying that phone issues were causing problems, otherwise the updates can't be applied under warranty. The warranty auditor will check all the claims and if it looks like there has been a lot of claims for the same thing on a lot of cars, they can void the claim and not pay the dealer.....
