Understanding Lemon Cars: Your Rights Under Australian Consumer Law (ACL)
Buying a new car is a significant event for many Australians—often second only to purchasing a home. It’s an investment fuelled by both need and desire. Whether you choose a family SUV, a luxury sedan, or a robust ute, you expect reliability, value for money, and peace of mind. But ending up with a so-called ‘lemon car’ can undermine those expectations.
But what happens when that dream vehicle turns out to be a lemon—spending more time in the workshop than on the road?
And what can you do if the dealership insists there is ‘nothing more’ they can do about your lemon car?
Unfortunately, many consumers are unaware of their rights when problems arise with a new ‘lemon’ vehicle. Dealers and manufacturers often focus on the length of the manufacturer’s warranty – whether it is three, seven, or even ten years – as if the warranty period alone determines whether a consumer is entitled to a remedy under Australian Consumer Law.
That is not the case.
The Australian Consumer Law Offers Protections Beyond the Warranty
The Australian Consumer Law (ACL), contained in Schedule 2 of the Competition and Consumer Act 2010 (Cth), provides consumers with powerful statutory guarantees whenever they purchase goods—including motor vehicles, and especially new lemon cars.
Importantly, these ACL rights exist independently of any manufacturer’s warranty and cannot be excluded, limited or contracted out of by dealers or manufacturers. This applies even after multiple unsuccessful attempts to fix a lemon car.
Many consumers are surprised to learn that their rights do not necessarily end when the manufacturer’s warranty expires. In fact, even if your new car becomes a lemon after the warranty period ends, you may still be entitled to a remedy under the ACL months or even years later.
The key question is not whether the manufacturer’s warranty has expired. The critical issue is whether the vehicle has failed to comply with one or more of the consumer guarantees under the ACL, thus making it a lemon.
What Are Consumer Guarantees?
When a consumer purchases a vehicle, the ACL guarantees that it will be:
-
- of acceptable quality;
-
- fit for any disclosed purpose;
-
- free from defects;
-
- safe;
-
- durable; and
-
- consistent with any description or representation made about it, so you don’t get stuck with a lemon.
A vehicle that develops significant defects, experiences repeated failures, or requires ongoing repairs may be considered a lemon and may fail to meet these guarantees. The legal focus is not merely on the mechanical fault itself, but whether that fault results in a breach of a consumer guarantee. Where a consumer guarantee has been breached, the consumer may be entitled to a remedy under the ACL, targeting lemon car scenarios.
Minor Failures versus Major Failures
The remedy available to a consumer depends on whether the failure is characterised as a minor failure or a major failure.
Minor Failures
A minor failure is a problem that can be repaired within a reasonable time.
Where the failure is minor, the supplier is generally entitled to choose the remedy. This will usually involve repairing the vehicle, although replacement or refund may also be offered.
Examples may include:
-
- replacement of a faulty sensor;
-
- repair of a defective electrical component;
-
- rectification of a manufacturing defect that can be repaired within a reasonable time.
The important consideration is whether the problem can be remedied within a reasonable period and without causing substantial inconvenience to the consumer.
Major Failures

- Case Study: Land Rover Lemon Law Decision (2024)
In a widely publicised 2024 Australian case, the owner of a new Range Rover endured persistent mechanical problems that repeated attempts at repair failed to fix. The court ultimately determined these ongoing faults constituted a ‘major failure’ under the Australian Consumer Law (ACL), requiring Land Rover to compensate the buyer. This case highlights that, even if a manufacturer resists or the vehicle has left the warranty period, Australian consumers can enforce their rights when faced with a genuine lemon car. The court’s decision gives practical effect to the ACL’s consumer guarantees, demonstrating that real remedies are available to Australians left with a defective ‘lemon’ vehicle.

A major failure is significantly more serious—and is often at the heart of ‘lemon’ car disputes.
Under the ACL, a vehicle may suffer a major failure—and potentially be classified as a lemon—where:
-
- a reasonable consumer would not have purchased the vehicle had they known about the problem;
-
- the vehicle is substantially unfit for its normal purpose and cannot be easily remedied within a reasonable time;
-
- the vehicle is unsafe; or the vehicle departs significantly from its description or demonstration model
Where there is a major failure (for example, a new car being declared a lemon), it is the consumer—not the supplier—who chooses the remedy.
The consumer may elect to:
-
- reject the vehicle and obtain a refund; or
-
- reject the vehicle and receive a replacement vehicle of the same type.
In some cases, consumers may also be entitled to recover reasonably foreseeable losses arising from the failure. These may include rental cars and more importantly, legal fees.
Don’t Be Misled About Your Rights
A common misconception is that a consumer can only obtain a refund or replacement if a vehicle has suffered a catastrophic mechanical failure.
That is simply not correct.
The ACL does not require an engine to explode or a transmission to completely fail before a consumer can establish a major failure. In appropriate circumstances, repeated defects, persistent faults, ongoing safety concerns or unsuccessful repair attempts may collectively amount to a major failure under the legislation.
Consumers should also be cautious of statements suggesting that their rights end when the manufacturer’s warranty expires.
In many cases, they do not.
When the New Car Warranty Expires: Are You Really Out of Options?
When purchasing a new vehicle, the warranty period often plays a significant role in the decision-making process. A seven-year unlimited kilometre warranty may appear far more attractive than a three-year limited warranty and can influence which brand a consumer ultimately chooses.
However, what happens when the warranty expires and a significant problem emerges shortly afterwards?
Many consumers are told they are “out of warranty” and therefore have no entitlement to assistance.
That advice is not always correct.
Consumer Guarantees Continue to Apply
The ACL provides protections that are separate from, and additional to, any manufacturer’s warranty.
A vehicle’s warranty period does not determine the lifespan of the consumer guarantees.
Instead, the law asks what a reasonable consumer would expect from a vehicle of that type, taking into account factors such as:
-
- the purchase price;
-
- the age of the vehicle;
-
- the vehicle’s nature and purpose;
-
- any representations made by the manufacturer or dealer; and
-
- the circumstances of the sale.
For example, a consumer who purchases a new vehicle for $80,000 may reasonably expect the engine and drivetrain to last significantly longer than the manufacturer’s warranty period, especially if that period is 3 years.
If a major component fails shortly after the warranty expires because of an underlying manufacturing defect or quality issue, the consumer may still have rights under the ACL.
Every case turns on its own facts and determining whether a consumer guarantee has been breached requires careful consideration of the vehicle’s history, the nature of the defect and the surrounding circumstances.
Know Your Rights
The reality is that many motorists incorrectly assume they have no options once their warranty has expired. Equally, some dealers and manufacturers do not always provide consumers with a complete explanation of their rights under the ACL.
Understanding the distinction between a manufacturer’s warranty and statutory consumer guarantees can be the difference between being left with a costly repair bill and obtaining the remedy to which you are legally entitled.
If your vehicle has experienced significant defects, repeated repairs or a major mechanical failure, it is important to obtain legal advice regarding your rights under the Australian Consumer Law, and we encourage you to contact us so we can assess your case individually.

Frequently Asked Questions (FAQs)
What is a ‘lemon car’ under Australian law?
A ‘lemon car’ is a vehicle that has one or more significant defects or repeated problems that substantially reduce its value, safety, or usability. Under the Australian Consumer Law (ACL), a car may be declared a lemon if it fails to meet the required consumer guarantees, such as being of acceptable quality or fit for its intended purpose.
Can I get a refund or replacement after the manufacturer’s warranty ends?
Yes, consumer guarantees under the ACL apply independently of the manufacturer’s warranty. Even after your warranty period has expired, you may still be entitled to a remedy—such as repair, refund, or replacement—if your car is a lemon due to a major failure.
What should I do if I think I’ve bought a lemon car?
Gather all documentation including your purchase contract, service and repair records, and any communications with the dealer or manufacturer. Seek tailored legal advice to understand your options and enforce your rights under the ACL.
