What are the Lemon Laws in Australia Under the ACL?

In Short

  • Australia has no specific lemon laws, but the Australian Consumer Law provides remedies for goods with major failures, including cars.
  • For a major failure, consumers can choose a repair, replacement, or refund, plus claim compensation.
  • Keep detailed records of defects, repairs, and communications to strengthen your claim.

Tips for Businesses

Clearly understand your obligations under the ACL and avoid misleading refund policies. If a product has a major failure, promptly offer the consumer their choice of remedy. Good record keeping, transparency, and proactive resolution can help prevent disputes and reduce the risk of heavy penalties.

If you have ever purchased a new car and discovered that something was faulty, whether the brakes fail, the steering malfunctions or strange noises emerge under the hood, you may have bought what is commonly known as a ‘lemon’. However, unlike the USA, Australia’s national consumer law framework does not include a specific lemon law. Instead, the Australian Consumer Law (ACL) core guarantees protect consumers. This article outlines the current consumer guarantees for lemons and explains what remedies you can access if you have purchased a lemon.

What is a Lemon?

According to the Commonwealth Consumer Affairs Advisory Council, a ‘lemon’ is a product that ‘simply will not function as intended, for reasons that are beyond the expertise of a reasonable repairer to remedy’. While people typically apply the term to motor vehicles, a ‘lemon’ encompasses any product or good that does not function. Under the ACL, where a major failure has occurred, consumers have several options. They can choose between a repair, refund or replacement and receive compensation equal to the value of the good. 

Common Types of Vehicle Defects

Lemon vehicles typically exhibit recurring problems that significantly impair functionality. Engine failures, transmission defects, electrical system malfunctions, and persistent brake issues represent the most common categories. Paint defects, air conditioning failures, and recurring mechanical breakdowns also qualify as major failures under the ACL when repair attempts prove unsuccessful or the defects substantially affect vehicle safety and performance.

Current Consumer Law Protections: ‘Repair, Replace, Refund’

Currently, core consumer guarantees apply under the ACL for ‘major failures’. Major failures occur when the good meets any of these criteria:

  • differs significantly from the sample or description;
  • proves substantially unfit for the purpose for which the provider commonly supplies the same good and cannot be remedied within a reasonable time; 
  • unfit for the purpose disclosed to the consumer, or for the purpose the consumer requested, and cannot be remedied within a reasonable time;
  • fails to the extent that a reasonable consumer would not have purchased the good had they understood the nature and extent of the failure; or 
  • demonstrates unacceptable quality because it is unsafe.

Where the failure constitutes a ‘major failure’, consumers can request a remedy. The ACL allows consumers to choose between a repair, replacement or refund and receive compensation for their loss. Businesses face penalties when they falsely represent that core guarantees are unavailable.

Generally, signs such as ‘No refund’, ‘No refunds on sale items’ and ‘No refunds after seven days’ are contraventions of the ACL. Companies displaying these signs face fines up to $10 million, while individuals face penalties up to $500,000.

Documentation and Evidence

When dealing with a potential lemon, you should maintain detailed records of all defects, repair attempts, and communications with suppliers. Record dates, symptoms, repair costs, and the time you spend without the vehicle. This evidence becomes essential when you pursue remedies under the ACL and strengthens your position during negotiations with manufacturers or dealers.

Law Reform and Specific Lemon Laws 

Australia currently lacks specific lemon laws. However, any future legislation should address the high monetary and emotional cost of obtaining legal redress by incorporating:

While no federal lemon laws exist yet, some states have taken proactive steps towards increasing consumer protections. For example, Queensland has made it easier for buyers of defective vehicles to pursue claims by changing procedural rules surrounding jurisdictional limits. 

Queensland lifted the jurisdictional limit for motor vehicle disputes from $25,000 to $100,000 in the Queensland Civil and Administrative Tribunal. This enables purchasers of new or used cars to pursue claims without facing costly litigation through Queensland’s court system.

Prevention Tips

You can reduce lemon risks by conducting thorough pre-purchase inspections and obtaining independent mechanical assessments. Research vehicle reliability ratings, request comprehensive service histories, and verify warranty coverage before you purchase. Understanding your ACL rights before problems arise enables you to respond more effectively to defects. Consider purchasing from reputable dealers who demonstrate a willingness to honour consumer guarantees.

Key Takeaways

While the ACL does not have any specifically drafted lemon laws, consumers maintain certain guarantees. When you purchase goods that fail to function as intended and providers cannot easily repair them within a reasonable timeframe, you can receive a refund, exchange or compensation. Remember that suppliers cannot override your ACL rights through contract terms or store policies that attempt to limit your remedies.
