Private-Sale Defective Motor Vehicle Claims: Twining v Mazda Australia Pty Limited [2022] NSWCATCD 39
Buying a used motor vehicle through a private sale can significantly restrict the remedies available to the purchaser. The consumer guarantees in the Australian Consumer Law (ACL) generally regulate supplies made in trade or commerce. A genuine private seller will therefore not ordinarily be liable under the ACL merely because the vehicle later develops a defect.
That does not necessarily mean that the purchaser has no rights against the vehicle’s manufacturer or Australian importer. In some circumstances, a later owner may be an “affected person” who can pursue a manufacturer under ss 271 and 272 of the ACL. Establishing such a claim requires proof of the original consumer supply, the claimant’s place in the chain of acquisition, a failure to comply with an applicable consumer guarantee, causation and recoverable loss.
In Twining v Mazda Australia Pty Limited [2022] NSWCATCD 39, NCAT initially found that it had jurisdiction to determine a manufacturer claim brought by a person who had acquired a used vehicle privately. The claim was nevertheless dismissed because the applicant did not prove an essential element of his entitlement to claim as an affected person.
The jurisdictional aspect of Twining should now be treated with considerable caution. It does not appear to have been cited or followed in any later published NCAT decision. More importantly, the Appeal Panel subsequently held in Pellatt v Ford Motor Company of Australia Pty Ltd [2025] NSWCATAP 276 that a purchaser who acquired a vehicle through a genuinely private sale was not a “consumer” for the purposes of Part 6A of the Fair Trading Act 1987 (NSW). NCAT therefore lacked jurisdiction, even though the proceeding was directed against the manufacturer.
A purchaser may consequently have to pursue any available ACL or warranty claim in a court with jurisdiction rather than NCAT.

Table of Contents
Key Takeaways
-
The ACL consumer guarantees will not ordinarily apply to the transaction between a buyer and a genuine private seller because the sale is not made in trade or commerce.
-
The description “private sale” is not conclusive. If the seller was in fact selling vehicles in the course of a business, different rights and remedies may arise.
-
A later owner may still have a substantive ACL claim against a manufacturer or importer as an affected person, but the claimant must prove that the statutory requirements are satisfied.
-
NCAT jurisdiction is a separate question from whether a claimant may have rights under the ACL. A valid cause of action does not itself confer jurisdiction on NCAT.
-
Although Twining found that NCAT had jurisdiction over a manufacturer claim following a private sale, the later Appeal Panel decision in Pellatt reached the contrary conclusion on the relevant statutory gateway.
-
Twining remains useful as an illustration of the evidence required in a manufacturer claim, but it should not be relied on as current authority that NCAT can hear a claim arising from a genuinely private acquisition.
-
Mechanical opinion evidence, the vehicle’s ownership and supply history, maintenance records and proof of loss should be compiled before proceedings are commenced.
Background to Twining v Mazda
The applicant acquired a used Mazda BT-50 from its previous owner in a private sale. After the vehicle suffered engine problems, he alleged that a defective exhaust gas recirculation cooler, commonly known as an EGR cooler, had caused or contributed to the engine failure.
His case was directed against Mazda Australia as the vehicle’s Australian importer or manufacturer, rather than against the private seller.
The applicant relied on the ACL, including the statutory guarantee of acceptable quality and the remedies available against a manufacturer. The case raised two distinct questions:
-
Did NCAT have jurisdiction under Part 6A of the Fair Trading Act 1987 (NSW) to determine the claim when the applicant had acquired the vehicle privately?
-
Had the applicant proved the elements required to recover damages from Mazda under the ACL?
NCAT answered the first question in the applicant’s favour but ultimately dismissed the claim on the evidence.
Private sales and the ACL
The ACL applies to supplies of goods and services in trade or commerce. A person selling their own vehicle on a genuinely private, one-off basis will not ordinarily be acting in trade or commerce or in the course of carrying on a business.
The statutory consumer guarantees therefore generally do not apply to that private seller.
This is why buying privately carries different legal risks from buying from a licensed motor dealer. A private purchaser should not assume that dealer-style remedies, statutory warranties or ACL consumer guarantees can be enforced against the seller.
There may still be other causes of action depending on the facts. For example, an express contractual promise or a false statement made by the seller may require separate consideration. Those claims are fact-sensitive and should not be confused with a consumer-guarantee claim against a supplier or manufacturer.
The label attached to the transaction is not necessarily decisive. Someone who regularly buys and sells vehicles for profit may be acting in the course of a business even if the advertisement or contract describes the transaction as a private sale. The substance of the seller’s activities must be examined.
The guarantee of acceptable quality
Section 54 of the ACL provides that goods supplied to a consumer in trade or commerce are guaranteed to be of acceptable quality.
Broadly, goods are of acceptable quality if they are:
-
fit for all purposes for which goods of that kind are commonly supplied;
-
acceptable in appearance and finish;
-
free from defects;
-
safe; and
-
durable.
The assessment is objective and takes account of matters including the nature and price of the goods, statements made about them, their age and condition, and all other relevant circumstances.
A used vehicle is not judged as though it were new. Equally, age or mileage does not automatically excuse a serious latent defect or a lack of reasonable durability. The question is what a reasonable consumer, fully acquainted with the vehicle’s condition, would regard as acceptable in the circumstances.
Claims against a manufacturer or importer
The ACL gives an affected person a direct right to recover damages from a manufacturer where goods fail to comply with certain consumer guarantees. Depending on the circumstances, an Australian importer can be treated as a manufacturer for ACL purposes.
Under s 271, an affected person may recover damages from a manufacturer for a failure to comply with an applicable guarantee. Section 272 addresses the measure of damages, which may include the reduction in the value of the goods and other reasonably foreseeable loss or damage caused by the failure.
Section 273 imposes a specific limitation period for an action for damages against a manufacturer.
These provisions can potentially benefit a later owner who did not buy directly from the manufacturer or an authorised dealer. However, the later owner must prove the statutory chain. It is not enough to prove only that the vehicle is now defective.
Relevant questions can include:
-
Was the vehicle originally supplied in trade or commerce?
-
Was the person involved in the original supply a “consumer” for ACL purposes?
-
Did the later owner acquire the vehicle from that consumer, or through a chain recognised by the ACL?
-
Was the later owner an affected person rather than someone who acquired the vehicle for resupply?
-
Did the relevant defect amount to a failure to comply with an applicable guarantee?
-
Did that failure cause the loss being claimed?
Substantive rights and forum jurisdiction are different
The ACL is Commonwealth legislation applied as a law of each state and territory. NCAT, however, is a statutory tribunal. It can determine only matters that NSW legislation authorises it to determine.
For a consumer claim under Part 6A of the Fair Trading Act, the claimant must satisfy the definitions and jurisdictional requirements in that Part. Those requirements are not necessarily identical to the broader class of people who may possess a substantive right under the ACL.
The distinction is central to understanding the effect of Twining and the later decision in Pellatt.
A person may potentially have an enforceable ACL or express-warranty claim but still be unable to bring that claim in NCAT. In that situation, the issue is not necessarily whether the legal right exists. The issue is whether NCAT has been given statutory power to determine it.
Why NCAT considered that it had jurisdiction in Twining
In Twining, NCAT considered the definitions of “consumer”, “supplier” and “consumer claim” in ss 79D and 79E of the Fair Trading Act.
Section 79E(2) extends the concept of a consumer claim to certain claims against a manufacturer where the direct supplier is not a party to the proceeding.
The Tribunal concluded that it had jurisdiction. It reasoned that the reference to a “direct supplier” in s 79E(2) did not require the person who sold the vehicle directly to the applicant to have supplied it in the course of a business.
On that construction, the private sale did not prevent NCAT from hearing the applicant’s manufacturer claim.
That finding was important because the private seller was not the respondent and the applicant was attempting to rely on rights said to arise against Mazda as manufacturer or importer.
Important caution: later authority on NCAT jurisdiction
Twining should be treated with caution on the question of NCAT’s jurisdiction. It was a first-instance decision and does not appear to have been cited or followed in any subsequent published NCAT decision.
More importantly, the Appeal Panel subsequently held in Pellatt v Ford Motor Company of Australia Pty Ltd [2025] NSWCATAP 276 that a purchaser acquiring a vehicle through a genuinely private sale is not a “consumer” under s 79D of the Fair Trading Act, because the vehicle was not supplied by someone carrying on a business.
Section 79E(2) did not overcome that jurisdictional requirement merely because the claim was brought against the manufacturer.
Accordingly, although Twining found that NCAT had jurisdiction over a manufacturer claim arising after a private sale, that reasoning is difficult to reconcile with the later Appeal Panel authority and should not be relied upon as establishing that NCAT can determine such claims.
A private purchaser may instead need to pursue any available manufacturer, warranty or ACL remedy in a court of competent jurisdiction.
In reaching its conclusion, the Appeal Panel in Pellatt agreed that the private supply lacked the necessary element of a supply by a person carrying on, or purporting to carry on, a business. It also held that s 79E(2) expands the kinds of claims that a qualifying consumer can bring against a manufacturer; it does not expand the statutory definitions of “consumer” or “supplier”.
That approach is consistent with Leach v Toyota Motor Corporation Australia Limited [2022] NSWCATCD 92, where the vehicle had been transferred by way of a private gift and the necessary supply by a business supplier was absent.
The practical position is therefore:
-
Twining records that NCAT accepted jurisdiction on the construction adopted in that case;
-
the later and more authoritative Appeal Panel reasoning in Pellatt rejects the essential basis of that construction; and
-
a claimant whose own acquisition was genuinely private should not assume that NCAT can determine a claim against the manufacturer, even if the claimant may possess a substantive ACL or express-warranty claim capable of being brought elsewhere.
NCAT’s monetary and time limits must also be considered in any matter that otherwise falls within its jurisdiction. Those limits do not cure the absence of the threshold jurisdictional relationship required by Part 6A.
The evidence required in a manufacturer claim
Twining demonstrates that a claimant must prove each element of the statutory cause of action. A serious mechanical failure and a plausible theory about a known defect do not, without more, establish liability.
A properly prepared claim may require:
-
the original contract, tax invoice or dealer records showing the first supply of the vehicle;
-
evidence identifying the original purchaser and the capacity in which that person acquired the vehicle;
-
documents tracing each later transfer of ownership;
-
the vehicle’s service, repair, recall and warranty history;
-
diagnostic records, photographs and retained components;
-
an independent expert report identifying the defect and explaining when and why it arose;
-
evidence distinguishing a manufacturing or durability problem from wear, misuse, modification or inadequate maintenance; and
-
invoices, valuations and other documents proving the amount and cause of each claimed loss.
Obtaining these materials can be more difficult after a private sale because the current owner may not have the original purchase documents or complete service history. That evidentiary gap should be investigated before a claim is filed.
The affected-person issue in Twining
The applicant needed to establish that he was entitled to invoke the manufacturer-remedy provisions as an affected person. That depended, in part, on proving that the relevant earlier acquisition was a consumer acquisition to which the statutory guarantee applied.
The Tribunal found that the applicant had not proved that the previous owner was a consumer.
The careful way to state the result is not that NCAT positively found that the applicant was not an affected person. Rather, he failed to prove an essential element grounding his right to bring a claim as an affected person under s 271.
This distinction matters. A claimant bears the burden of proving entitlement to the statutory remedy. If the evidence does not establish the character of the original supply or acquisition, the claim may fail even though the manufacturer cannot affirmatively prove that the earlier purchaser was not a consumer.
In practical terms, a later owner may need documents or evidence from a transaction to which they were not a party. That can include the original dealer invoice, finance records, evidence about the original purchaser’s intended use and information about whether the vehicle was acquired for resupply or business purposes.
Section 54 and acceptable quality
A vehicle’s mechanical failure is relevant evidence, but it does not automatically establish that the vehicle failed the guarantee of acceptable quality when it was supplied.
The Tribunal or court must consider the vehicle’s age, mileage, purchase price, maintenance, use and the nature of the alleged defect.
For a manufacturer claim, the applicant must connect the alleged condition of the goods with the guarantee that applied to the original consumer supply. In a used-vehicle case, expert evidence will often be required to address:
-
the precise component that failed;
-
whether the failure resulted from an inherent defect or inadequate durability;
-
whether the defect was present, developing or latent at the relevant time;
-
whether servicing, later repairs, modifications or use contributed to the failure; and
-
what repair was reasonably required.
General assertions that a model has a “common problem”, online discussions, or the fact that other vehicles have experienced similar failures may identify an issue for investigation. They will rarely substitute for admissible evidence about the particular vehicle.
The expert should ideally identify the material considered, the inspections conducted, the applicable technical principles and the reasoning connecting the alleged defect to the failure. A bare conclusion that a component was defective may carry limited weight if the report does not explain how that conclusion was reached.
Causation and damages
Section 272 does not make the manufacturer liable for every expense incurred after a breakdown. The claimant must establish a sufficient causal connection between the failure to comply with the guarantee and the loss claimed.
For example, the evidence may need to show that the alleged EGR cooler problem caused the engine damage, rather than merely existing at the same time.
The claimant must also prove the reasonable cost of repair, any reduction in value and any consequential losses. Claimed expenses should be supported by invoices, expert opinion and evidence showing that they were reasonably foreseeable consequences of the established failure.
The manufacturer may dispute:
-
the existence of a defect;
-
the cause of the mechanical failure;
-
the condition of the vehicle when originally supplied;
-
the adequacy of its service history;
-
the effect of later repairs or modifications;
-
the reasonableness of the proposed repair; and
-
the amount and foreseeability of the claimed loss.
A persuasive claim should address those issues directly.
A claimant must also take reasonable steps to avoid unnecessary loss. Continuing to drive a vehicle after warning signs or a diagnosis may create disputes about whether some of the later damage could have been avoided.
The Tribunal’s decision
NCAT dismissed the application.
Although the Tribunal held that it had jurisdiction on its construction of the Fair Trading Act 1987 (NSW), the applicant did not prove the statutory foundation necessary to recover damages from Mazda.
In particular, the Tribunal held that the applicant did not establish that the previous owner was a consumer for the purpose of the affected-person claim.
The result illustrates two separate barriers:
-
Jurisdiction: Can the chosen forum lawfully determine the dispute?
-
Merits: Can the claimant prove every element of the cause of action and the loss claimed?
Twining passed the first barrier on the reasoning adopted by the first-instance Tribunal but failed on the second.
After Pellatt, a comparable private-sale claimant is likely to encounter the jurisdictional barrier in NCAT before the merits are considered.
Why the case remains significant
Twining remains useful because it shows how a person who bought a vehicle privately may attempt to frame a direct claim against a manufacturer or importer.
It also demonstrates why the vehicle’s history and the status of earlier purchasers can be decisive. A claimant who cannot prove the original consumer supply may be unable to establish standing as an affected person, regardless of the seriousness of the mechanical failure.
Its significance on NCAT jurisdiction is now primarily cautionary. The later Appeal Panel decision in Pellatt makes it unsafe to present Twining as authority that NCAT can hear manufacturer claims following a private acquisition.
The case also highlights a broader procedural lesson: choosing the wrong forum can cause delay, additional cost and limitation risk. The appropriate court or tribunal should be identified before proceedings are commenced, particularly where the claimant acquired the goods through a private sale, gift or other non-business transaction.
Practical lessons for purchasers of privately sold vehicles
Before purchasing
-
Arrange an independent mechanical inspection and written report.
-
Obtain the vehicle identification number, service history, repair invoices and recall information.
-
Ask for the original purchase invoice and any remaining manufacturer-warranty documents.
-
Conduct the appropriate registration, encumbrance and written-off vehicle checks.
-
Record representations about the vehicle’s condition, history, mileage and known faults in writing.
-
Do not assume that ACL guarantees applying to dealer sales will apply against a private seller.
After discovering a defect
-
Stop using the vehicle if continued operation could worsen the damage or create a safety risk.
-
Notify the seller and any relevant manufacturer or warranty provider promptly and in writing.
-
Preserve replaced parts and request complete diagnostic records.
-
Obtain an independent opinion addressing defect, causation, durability and repair cost.
-
Collect evidence of the original consumer supply and subsequent ownership chain.
-
Retain invoices, towing records, hire-car expenses and other evidence of loss.
-
Check the applicable limitation periods before extended negotiations or repairs cause delay.
-
Obtain advice about the correct forum. Following Pellatt, NCAT should not be assumed to have jurisdiction where the vehicle was acquired in a genuinely private sale.
How Arida Lawyers can assist

Frequently Asked Questions
Q1. Does the Australian Consumer Law apply when I buy a car privately?
The ACL consumer guarantees will not ordinarily apply against a genuine private seller because that person is not supplying the vehicle in trade or commerce.
The position may differ if the seller was actually trading in vehicles, despite describing the transaction as private. Contractual or misrepresentation remedies may also arise depending on what was said and agreed.
Q.2 Can I bring an ACL claim against the manufacturer if I bought the vehicle privately?
Potentially. A later owner may qualify as an affected person and may have a direct damages claim against a manufacturer or qualifying importer under ss 271 and 272.
The claimant must prove the original consumer supply, the chain of acquisition, the relevant guarantee failure, causation and loss. A private purchase does not itself prove or disprove those elements.
Q3. Can NCAT hear my claim against the manufacturer?
Following Pellatt v Ford Motor Company of Australia Pty Ltd [2025] NSWCATAP 276, NCAT should not be assumed to have jurisdiction where the claimant acquired the vehicle through a genuinely private sale.
The Appeal Panel held that the claimant was not a “consumer” under s 79D of the Fair Trading Act because the immediate supply was not made by a supplier carrying on a business. Section 79E(2) did not change that result merely because the respondent was the manufacturer.
Q4. Did Twining v Mazda decide that NCAT has jurisdiction over private-sale vehicle claims?
The first-instance Tribunal in Twining accepted jurisdiction over the manufacturer claim.
However, Twining does not appear to have been cited or followed in subsequent published decisions, and its jurisdictional reasoning is difficult to reconcile with the later Appeal Panel decision in Pellatt. It should therefore be treated with caution and not relied upon as establishing current NCAT jurisdiction.
Q5. Does Pellatt mean that I have no claim at all?
Not necessarily. Pellatt concerned NCAT’s statutory jurisdiction.
The Appeal Panel acknowledged that a claimant might be entitled to enforce an express manufacturer warranty in another jurisdiction. Whether an ACL, warranty, contractual or other claim exists, and which court can determine it, depends on the particular facts.
Q.6 What evidence is most important in a defective vehicle claim?
The key materials commonly include:
-
the original purchase documents;
-
the ownership chain;
-
service and repair records;
-
diagnostic results;
-
warranty communications;
-
an independent expert report;
-
photographs or retained parts; and
-
proof of the loss claimed.
The expert evidence should explain not only what failed, but why it failed and how that failure caused the claimed damage.
Q7. Is a manufacturer responsible for every major failure in a used vehicle?
No. Liability depends on whether an applicable consumer guarantee was breached and whether that breach caused the loss.
The vehicle’s age, mileage, price, maintenance, use and condition are relevant. Ordinary wear, misuse, modifications or inadequate servicing may affect the outcome.
Q8. How long do I have to bring a manufacturer claim?
Section 273 of the ACL contains a specific limitation period for damages claims against manufacturers. It runs by reference to when the affected person became aware, or ought reasonably to have become aware, of the loss and the identity of the manufacturer.
Other claims and forums can have different time limits. Advice should be obtained promptly because using the wrong forum does not necessarily protect a claimant from an expiring limitation period.
