California used-car buyers get a 3-day return right starting October 1
Starting October 1, dealers must disclose total prices upfront and let buyers return used vehicles priced at $50,000 or less within three days for any reason.
California's Combating Auto Retail Scams (CARS) Act took effect October 1, 2026, requiring California dealers to disclose total prices upfront and restricting misleading add-on charges, while also giving buyers of used vehicles priced at $50,000 or less a three-day right to return the vehicle for any reason. The three-day return right applies to retail purchases and leases from California dealers but excludes new cars, fleet sales, lease buyouts, auctions, and motorcycles.
The act targets deceptive pricing practices common in used-car sales. Dealerships must now show buyers the complete price in advertisements and initial communications, clearly mark optional add-ons as non-required in writing, and refrain from charging for products that provide no consumer benefit, such as oil-change plans for electric vehicles. All records must be kept for two years.
The deceptive practices the law prevents
Before the CARS Act, dealers commonly advertised artificially low base prices and then added substantial fees during negotiation—a practice known as bait-and-switch pricing. Dealers would list a vehicle at one price in an advertisement, then reveal during the sales process that market adjustments, dealer prep charges, pre-fitted accessories, and mandatory add-ons pushed the actual cost significantly higher. The law now requires dealers to show the "true cash price required to complete the transaction" upfront in all advertisements and written communications, eliminating the gap between advertised and actual cost.
Dealers also profited from selling add-on products with little or no benefit to consumers. The law specifically bans services like oil-change contracts on battery-electric vehicles and diluted nitrogen tire inflation that fails purity standards. Worthless GAP insurance policies that exclude the purchased vehicle or fail to meet California requirements are also prohibited. The law requires dealers to pay vendors for legitimate service contracts within 10 days, ensuring consumers' coverage activates promptly rather than being delayed by dealers withholding payment.
Total price and add-on disclosure requirements
Dealers must display the total price of a vehicle in every advertisement and the first written communication about that specific car, whether by email, text, or printout. The total price includes the dealer's asking price, any markups, and installed options—but excludes only taxes, title, registration, and license fees. Mandatory charges such as dealer prep and market adjustments must be folded into the advertised price rather than hidden as surprise charges during negotiation. Dealers must also state the complete amount buyers will pay over a loan term if financing the purchase, not just the monthly payment.
Add-on products such as extended warranties, GAP insurance, paint protection, theft-recovery systems, and service contracts must be clearly marked as optional in writing before any purchase. Dealers cannot bundle them into quoted prices or condition the sale on purchasing them. The law specifically prohibits charging for add-ons with no consumer benefit. Dealers must pay vendors for add-ons within ten days of purchase and retain all advertising, pricing communications, purchase agreements, add-on consents, and cancellation notices for two years to prove compliance.
The 3-day return window
Buyers of used vehicles priced at $50,000 or less can cancel purchases and return cars within three calendar days of signing for any reason. The clock starts the day after the contract is signed; if the third day falls on a day the dealership is closed, the deadline extends to the next day it is open. The return right ends once a vehicle exceeds 400 miles of driving.
To return a vehicle, buyers must bring it in during business hours in the same condition with normal wear and tear accepted, along with everything else they received in the deal. Dealers must cancel the contract and refund the buyer within 48 hours. If the buyer traded in a vehicle, the dealer must return it, or if already sold, pay the buyer the greatest of its contract value, sale price, or fair market value, minus any loan still owed on it.
“Dealers must mark add-ons as optional in writing and cannot charge for products providing no consumer benefit, such as oil-change plans for electric vehicles.”
Restocking and mileage fees
When returning a vehicle, dealers may charge a restocking fee calculated at 1.5 percent of the sale price, with a minimum of $200 and a maximum of $600. If a buyer drove the car more than 250 miles, dealers can add $1 per mile over 250, capped at an additional $150. Both fees are deducted from the refund. A buyer who drove 320 miles would face $70 in mileage charges plus the restocking fee.
Before signing, check the advertised price against the purchase agreement and confirm taxes and fees are listed separately. Ask about any add-ons and verify they are marked as optional in writing. Note the odometer reading and take photos before leaving the lot. Consider an independent mechanical inspection within the three days if concerned about defects. Complaints about violations can be filed with the California Attorney General at 1-800-952-5225, or buyers can pursue small claims court or civil litigation.
