The competition watchdog is taking 11 Harvey Norman franchisees to the Federal Court for allegedly misrepresenting consumer rights.
The ACCC alleges the franchisees of the stores misled and deceived customers by making false claims about warranties and refunds.
As part of the action, the ACCC is seeking penalties, declarations, injunctions and costs.
It is part of the commission's campaign on consumer guarantees and it says it is investigating other large companies for similar breaches.
ACCC chairman Rod Sims said in a statement that consumers had the right to certain remedies when goods were not of acceptable quality nor fit for the purpose for which they were sold.
"These rights cannot be excluded, restricted or modified," he said.
"For example, if an item purchased breaks down within a short time of being purchased, the consumer may be entitled to a refund or a replacement item."
The ACCC says in some cases the franchisees said they had no obligation to provide remedies unless the store was notified within a specific period of time on particular items such as large appliances or items priced below a certain amount, or if the goods were still covered by the manufacturer's warranty.
The ACCC also alleges some consumers were told they must pay a fee for the repair and return of faulty products.
