If a used car has turned bad, your options depend on whether you bought from a dealer or privately. Here is what the law actually gives you, how to escalate step by step, and the evidence that wins.
Australia has no single "lemon law" that lets you simply hand a car back. What you have instead is the Australian Consumer Law, the NSW dealer statutory warranty, and, for serious cases, NSW Fair Trading and NCAT. How much protection you have depends heavily on whether you bought from a licensed dealer or a private seller. This page is general information, not legal advice; for your specific situation, contact NSW Fair Trading.
A dealer purchase comes with real, enforceable rights. A private "as-is" purchase comes with almost none unless you can prove the seller actively misrepresented the car. Know which one you are in before you spend energy.
When you buy from a business (a dealer), the car comes with automatic consumer guarantees that cannot be signed away.
A fault so serious you would not have bought the car had you known, or that makes it unsafe. For a major failure you can choose a refund or replacement, not just a repair.
A fault the business is entitled to fix within a reasonable time. If they refuse or take too long, it can escalate to a major-failure remedy.
The car must be safe, durable, and free from defects given its age, km, and price. A 2012 car with 180,000 km is held to a different standard than a 2022 car, but it still must be roadworthy and as described.
The car must match how it was advertised and described, "one owner", "no accidents", "full service history". If those claims are false, that is a breach.
Most used cars sold by a licensed NSW dealer that are under 10 years old and under 160,000 km at sale.
Defects present at the time of sale, for 3 months or 5,000 km, whichever comes first.
You generally need to show the seller misrepresented the car: lied about km, hid a known major fault, or sold a stolen or written-off car as clean.
A wound-back odometer or an undisclosed written-off history are the strongest cases, because they are documentable. Your inspection report, PPSR certificate, and the advert are your evidence.
Without misrepresentation, a private sale is final the moment you pay. There is no warranty, no cooling-off, and no Fair Trading remedy for ordinary faults. This is precisely why an inspection before you pay matters most on private sales.
State the fault, the remedy you want, and a deadline. Keep it factual. Email or text creates a record.
If they do not resolve it, lodge a complaint. Fair Trading can help with dispute resolution between you and the dealer.
If Fair Trading cannot resolve it, apply to the NSW Civil and Administrative Tribunal for a binding decision.
For matters outside NCAT's scope, the Local Court is the last resort. Most cases never get here.
"The buyers who win at NCAT are the ones with documents. A dated independent inspection report is the strongest one you can bring."
Lead Mechanic, Sydney Mobile Car InspectionsTalking to the seller and Fair Trading can take a few weeks. From an NCAT lodgement to a hearing is often a couple of months, and many matters settle once evidence is exchanged. Outcomes range from a repair order to a refund or compensation. Be patient, stay organised, and keep everything in writing.
The cars that end up at NCAT are almost always the ones bought without an inspection. A pre-purchase inspection before you pay catches most of these problems while you can still walk away, and if you do end up in a dispute, the report becomes your evidence.

Get in touch ›There is no general 7-day return right. A 1-business-day cooling-off applies only to dealer finance contracts. Otherwise your rights come from the statutory warranty and the Australian Consumer Law, not an automatic return window.
Enforcing a statutory warranty against a dealer that has stopped trading is very hard. You may have limited options through the Motor Dealers compensation arrangements; Fair Trading can advise. It is a key reason to inspect before buying.
NCAT lodgement fees are modest, typically a small filing fee that varies by claim amount, far less than court. Check the current NCAT fee schedule when you apply.
From lodgement to a hearing is often a couple of months, sometimes longer. Many matters settle at or before the first hearing once both sides exchange evidence.
Only if you can show misrepresentation, such as a wound-back odometer or a hidden written-off history sold as clean. As-is private sales are otherwise very hard to unwind.
