A used car bought from a licensed dealer in most Australian states comes with a statutory dealer warranty — typically 3 months / 5,000 km, longer in some states for newer vehicles. That sits on top of the consumer guarantees in the Australian Consumer Law (ACL), which never expire and apply to every vehicle sold by a dealer regardless of age or kilometres.
If a fault appears within the warranty period and the dealer refuses to repair it, you have legal grounds to compel them to.
Common dealer pushbacks (and why most are wrong)
- “It was sold as-is.” Dealer warranties and the ACL can’t be excluded by an “as-is” or “no warranty” clause. Those clauses are unenforceable when the seller is a dealer.
- “You drove it 200km / drove it for two weeks before complaining.” Reasonable use doesn’t void the warranty. The dealer needs to point to specific damage YOU caused, not just normal use.
- “The warranty doesn’t cover that part.” The statutory warranty covers things that affect roadworthiness or major function — engine, transmission, brakes, electrical systems, body integrity. It’s broader than dealers usually claim.
- “You’ll have to pay diagnostic fees first.” If the fault is covered, diagnostic costs aren’t your problem.
The Notice to Remedy Breach
When the dealer is acting in breach of the warranty (or the ACL guarantees), the right opening move is a Notice to Remedy Breach. It’s stronger than a generic complaint letter because it:
- Identifies the specific contractual or statutory breach
- Cites the dealer warranty provisions and ACL sections
- Demands the breach be remedied (the car repaired or replaced) within a clear timeframe
- States what happens if the deadline isn’t met — typically tribunal action
- Establishes the formal record you’ll need at the tribunal stage
The dealer now knows you’ve identified the breach precisely and you’re prepared to escalate. Most repairs get done.
If the dealer still refuses
The next step depends on the value of the claim and your state. For amounts up to roughly $25,000–$100,000 (depending on state), your civil tribunal is the right venue: NCAT (NSW), QCAT (QLD), VCAT (VIC), SAT (WA), SACAT (SA), ACAT (ACT), NTCAT (NT), or the Magistrates Court (TAS).
