The ACCC are not going to want to know about this and besides if you go through their record of taking action against companies they lose the vast majority of cases. Lawyers will cost money and you will ultimately lose.
Best course of action is to negotiate an outcome but knowing Ford doubt they will.

OP but have played and payed myself. I had a clutch explode at Sandown with just 5k on it.
If you want to test these cars out please do it at the track. Yes it voids warranty but its far safer than on public roads. And if you do you can't expect that issues won't crop up they most definitely do.
You play you pay.
