There is no buyer’s remorse, cooling-off, or right-to-rescind law that requires the seller of a new or used car to cancel the sale or accept the return of the car. When you sign the contract for the purchase or lease of the car, you are legally obligated to the purchase or lease. Because of the finality of the lease or purchase agreement, it is important to carefully read and understand the agreement before you sign it—and to determine whether buying or leasing the car is a good financial decision for you. Some state laws require car dealers to offer extra protections for buyers of used cars—such as a contract cancellation option agreement that the buyer may purchase for an additional fee, and that will allow the buyer to return the car and cancel the contract within a short period of time (2 days).

In Hawaii, there is no specific buyer's remorse, cooling-off, or right-to-rescind law that obligates a car dealer to cancel a car sale or accept a return once the contract for the purchase or lease of a new or used car is signed. Once you sign a vehicle purchase or lease agreement in Hawaii, you are legally bound to the terms of that contract. It is crucial to thoroughly review and understand the contract before signing it, and to ensure that the financial commitment of buying or leasing the vehicle aligns with your financial situation. While some states may have laws that require car dealers to offer additional protections, such as a contract cancellation option for used cars, Hawaii does not mandate such protections. Therefore, consumers in Hawaii should exercise due diligence and consider all aspects of the transaction before finalizing a car purchase or lease.
