Performax Warranty Policy

Performax International offers an industry exclusive four year/120,000km factory backed new car warranty with 24 hour Road Side Assist. This is backed 100% by our factory; it is not an after-market new car warranty or mechanical warranty as favoured by most companies.

A Performax Warranty is all about looking after the customer, not looking for reasons to decline a claim. The customer doesn’t call an office in a major city and talk to an operator that knows nothing about the vehicle, and only thinks of them as a number; they call their Performax Dealer or Head Office and deal direct with an employee that usually knows what they are talking about.

Performax dealership network

Performax International operates the only original equipment manufacturer (OEM) style dealership network in Australia, with dealers throughout the country stocking and servicing our vehicles. Customers often question the ability to get help when travelling in remote areas; it’s no different to any other modern vehicle.

Basic repairs can be done anywhere by any competent mechanic, and Performax is happy to offer them assistance over the phone. Most common parts are carried in Australia and can be despatched same day, just like a Toyota. And just like a Toyota if it’s not a common replacement part it gets flown in from overseas usually within seven to 10 days.

Performax parts

Performax International carries an extensive range or spare parts, genuine and aftermarket accessories. Customers have the ability to customise their vehicles to suit the application, whether it be outback touring, heavy duty towing, or a show pony we can accommodate.


Brought your own vehicle in to Australia for us to convert it? Your conversion has its own 12 month / 20,000km warranty.
