What I've been told by insiders at one Sydney dealer would get my post deleted under the name and shame rule.
Suffice to say if you take a car to a dealer when it is still under warranty, name every little fault (if/any) you know of and ask for a summary of any fault identified by the diagnostic computer and by mechanics undertaking the work. If it subsequently fails you have a documantary record the fault was present in the warranty period.
