What Australian Consumer Law actually says.
Under the Australian Consumer Law, a new vehicle comes with statutory consumer guarantees that exist independently of any dealer service agreement. The ACCC has stated plainly that manufacturers and dealers cannot refuse a warranty claim simply because the vehicle was serviced by an independent workshop, as long as the servicing was carried out according to the manufacturer's specification, at the specified intervals, by a qualified person, using appropriate parts and fluids.
That is the entire test. Not who owns the workshop, not whether the sign out the front carries the manufacturer's badge. Specification, interval, qualification, documentation.
Where owners do run into trouble is when servicing has been done cheaply and vaguely: an unspecified oil grade, an interval stretched past the schedule, or an invoice that says 'service' and nothing more. Those cases are avoidable, and they are the reason our invoices read the way they do.
