California's CARS Act Is Now in Effect: What Car Buyers Need to Know
Quick Answer: Senate Bill 766, the California Combating Auto Retail Scams Act, requires dealers to show the vehicle's full total price in advertisements and first written communications, label every add-on product as optional in writing, stop charging for add-ons that provide no real benefit to the buyer, and give purchasers of qualifying used vehicles priced at $50,000 or less a three-day right to cancel.
For anyone who has ever sat at a finance desk watching a monthly payment number shift while line items appeared from nowhere, this law addresses exactly that experience.
The California New Car Dealers Association called it the biggest change to how vehicles are sold in the state since 2005. What it actually requires, and what it does not cover, is worth understanding before your next dealership visit.
The law applies to all licensed California dealers selling or leasing new and used vehicles. It does not apply to private-party sales. And once you close the deal, the clock for transferring the title to your name through the California DMV starts immediately.
The Total Price Rule: What Dealers Must Show You Now
The most immediate change affects the number you see before you ever walk into a dealership.
Dealers must disclose a vehicle's total price in ads and in their first written response to a customer inquiry about a specific vehicle. That total price must include dealer price adjustments and any items already installed on the car.
It excludes taxes, government fees, and rebate deductions, which are genuinely variable and cannot always be fixed at the advertising stage.
This is a meaningful shift from how dealership advertising has historically worked in California. Advertised prices have often reflected a stripped base figure, with installed accessories, market adjustment markups, and dealer-added products folded in later at the negotiating table. Under the CARS Act, the total price must also appear in the dealer's first written response to a consumer inquiry for a specific vehicle, such as an email or text.
When monthly payment estimates are presented, sellers must simultaneously reveal the cumulative payoff amount over the loan term, alongside every financing assumption, such as required cash down or vehicle trade equity. The monthly payment has long been the figure dealers use to anchor negotiations because it obscures the total cost of the transaction.
The law now requires the total to be visible alongside it.
The practical implication: if a dealer sends you an email quoting a price on a specific vehicle, that price must already reflect any dealer markups and installed items. What you see in writing before you arrive should be what the vehicle actually costs at the dealership, before taxes and government fees.
Add-On Rules: Optional Means Optional Now
The add-on section of the CARS Act addresses one of the most consistent sources of buyer frustration at California dealerships: products that appear on a purchase contract without having been clearly presented as a choice.
Optional add-ons, including warranties, GAP coverage, and theft-protection products, must be clearly identified as optional before a buyer signs. The dealer must disclose in writing that the add-on is not required to complete the purchase or lease, list its price separately from the vehicle's total price, and confirm that declining it will not affect financing approval or the terms of the deal.
The law prohibits charging for add-on products that cannot deliver a meaningful benefit to the buyer, the vehicle, or the transaction. Specific examples now outlawed include maintenance or oil-change contracts sold on battery-electric vehicles, diluted nitrogen tire inflation that falls short of 95% chemical purity, and GAP policies that exclude the purchased vehicle model or fail California's statutory criteria.
Disclosure requirements that previously applied only to financed sales now extend to lease and cash deals as well, covering all dealer add-ons regardless of payment method. Whether you are financing, leasing, or paying cash, every add-on must be disclosed as optional before you sign.
Dealers are also required to pay third-party providers of add-on products within ten days of the sale. This rule addresses situations where a dealer collected payment for a product but never actually enrolled the buyer with the provider.
The Three-Day Cancellation Right for Used Car Buyers
Used vehicle buyers covered by the CARS Act are retail buyers and lessees of a used vehicle priced at $50,000 or less from a California dealer. For this group, the law creates a cancellation right that did not previously exist.
A buyer in this category has three days to return the vehicle and receive a full refund. If the buyer wants to cancel, the dealer has 48 hours to cancel the contract and issue the refund. The three-day window was explicitly designed to give buyers time to check for unrepaired safety recalls, which can only be verified after leaving the dealership.
Several conditions apply:
- Dealers may charge a stocking fee, and the vehicle cannot have been driven more than 400 miles before it is returned
- The cancellation right does not apply when a lessee already in possession buys out their own lease
- Motorcycles are not "used vehicles" for the purposes of this provision
- Used vehicles sold at auction are also excluded
SB 766 repeals certain older contract cancellation option requirements that existed for used vehicle sales, replacing them with the new three-day regime.
One important clarification: California does not have a cooling-off period for new vehicle purchases. The three-day cancellation right applies only to qualifying used vehicles priced at $50,000 or less. A new car purchase is final at signing.
Financing Disclosures: What Changed
The CARS Act prohibits dealers from making misrepresentations regarding material information about the costs or terms of purchasing, financing, or leasing a vehicle, including any costs, limitations, benefits, or any other aspect of an add-on product or service.
For buyers who finance through the dealership, this has several practical implications. The total amount you will pay over the life of the loan must be shown alongside any monthly payment quote. Financing preapproval or guarantees cannot be misrepresented. A dealer cannot tell you that a specific add-on is required for financing approval if it is not.
The law mandates a clear and conspicuous standard for disclosures, including written comparisons between payment options during negotiations, and mandates disclosure translation requirements for transactions negotiated primarily in a foreign language. Dealers are required to provide disclosures in the language used during negotiations if that language is Spanish, Chinese, Tagalog, Vietnamese, or Korean.
The CARS Act also affects indirect lenders, meaning banks and credit unions that purchase loan contracts from dealers. Because auto loan contracts are subject to California's Rees-Levering Act and the Federal Trade Commission's Holder Rule, compliance deficiencies or misrepresentations made during the dealer's sales process can carry over to the financial institution holding the loan paper. Lenders have been updating their dealer agreements to reflect these new obligations.
What the CARS Act Does Not Cover
The CARS Act applies to licensed California motor vehicle dealers. It does not apply to private-party sales between individuals, which continue to operate under general consumer protection law and the existing framework of the California Vehicle Code.
For a private-party purchase, the buyer retains no three-day cancellation right, add-on disclosures are not required, and total price transparency is not mandated. These are transactions where buyers carry more due-diligence responsibility: a vehicle history report, an independent pre-purchase inspection, and a verification of the seller's identity against the title remain as important as ever.
The CARS Act is enforceable by the California Attorney General, local district attorneys, and the DMV. Dealers are required to keep records of pricing, contracts, and complaints for at least two years. The recordkeeping requirement gives enforcement agencies the documentation needed to pursue violations after the fact.
After the Purchase: Title Transfer and the 10-Day Deadline
Whether you bought from a dealer or a private seller, completing the title transfer is your legal obligation once the purchase closes.
Under California Vehicle Code Section 5600, any change in ownership must be reported to the DMV within 10 days of the sale date. Late transfer penalties start at $15 on day 11 and increase based on additional days past the deadline.
For dealer purchases, the dealership typically handles the title transfer as part of the closing process and submits the paperwork to the DMV on the buyer's behalf. Confirm before leaving the dealership that this has been initiated.
For private-party purchases, the title transfer is entirely the buyer's responsibility, and the 10-day clock runs from the date on the bill of sale.
If you exercised the three-day cancellation right and returned a qualifying used vehicle, the title transfer obligation does not arise because the sale was unwound before the 10-day window closed. But once that window passes and you have decided to keep the vehicle, the title transfer must be completed.

Frequently Asked Questions
What is California's CARS Act?
The California Combating Auto Retail Scams Act, Senate Bill 766, took effect October 1, 2026. It requires licensed California car dealers to disclose a vehicle's total price in advertisements and first written communications, label all add-on products as optional in writing, stop charging for add-ons that provide no meaningful benefit, and give buyers of qualifying used vehicles priced at $50,000 or less a three-day right to cancel.
Does the CARS Act apply to new car purchases?
The pricing, add-on, and financing disclosure rules apply to both new and used vehicle sales and leases at licensed California dealerships. The three-day cancellation right applies only to used vehicles priced at $50,000 or less. New vehicle purchases remain final at signing.
What is included in the "total price" under the CARS Act?
The total price must include dealer price adjustments and any items already installed on the vehicle. It does not include taxes, government fees, or rebate deductions, which are variable and cannot always be fixed at the advertising stage. The total price must be shown in any advertisement referencing a specific vehicle and in the dealer's first written response to a customer inquiry.
Can a dealer still charge for add-ons under the CARS Act?
Yes, but only with specific conditions. The dealer must disclose each add-on in writing as optional, list its price separately from the vehicle total, confirm that declining it will not affect financing approval or deal terms, and pay the third-party provider within 10 days of the sale. Dealers are prohibited from charging for add-ons that provide no meaningful benefit to the buyer, the vehicle, or the transaction.
What are examples of add-ons that are now prohibited?
The law specifically identifies maintenance or oil-change contracts sold on battery-electric vehicles, diluted nitrogen tire inflation that does not meet the 95% purity threshold, and GAP insurance policies that exclude the specific vehicle being purchased or fail California's statutory criteria for such products.
I bought a used car under $50,000 from a dealer. What is my three-day cancellation right?
You have three calendar days from the date of purchase to cancel and receive a full refund. If you decide to cancel, notify the dealer, and they have 48 hours to cancel the contract and issue the refund. Conditions apply: a stocking fee may be charged, and the vehicle cannot have been driven more than 400 miles before return. The right does not apply to motorcycles, vehicles sold at auction, or lessees buying out their own lease.
Does the CARS Act apply if I buy a car from a private seller?
No. The CARS Act applies only to licensed California motor vehicle dealers. Private-party sales between individuals are not covered. For private-party purchases, buyers should conduct their own due diligence, including a vehicle history report and a pre-purchase mechanical inspection.
How long do I have to transfer the title after buying a car in California?
Under California Vehicle Code Section 5600, the title transfer must be filed with the DMV within 10 days of the sale date. For dealer purchases, the dealer typically handles this. For private-party purchases, the buyer is responsible. Late transfer penalties start at $15 on day 11 and increase from there.

Yes. For private-party purchases, Xtreet.com's title transfer service handles the application and DMV submission online as a licensed California DMV partner, without requiring a DMV office visit. The platform covers the filing, tracks the status, and handles supporting documentation.
Does the CARS Act affect how financing is presented at the dealership?
Yes. When a dealer presents monthly payment figures, they must simultaneously show the total cumulative payoff amount over the loan term and all financing assumptions, such as the required down payment or trade-in equity. Dealers cannot misrepresent financing preapproval, guarantee approval, or claim that any add-on product is required for financing when it is not.
Conclusion
The California CARS Act changes three things that have frustrated car buyers in the state for years:
- the total price is now required upfront rather than revealed at the finance desk
- every add-on must be labeled "optional" in writing before you sign
- buyers of qualifying used vehicles have three days to reconsider a purchase before it becomes permanent
Economists project the law will save California car buyers $234 million and 8.5 million hours of time each year.
The law covers what happens at the dealership. What happens after the purchase, transferring the title to your name and completing the registration, remains the buyer's responsibility and operates on the DMV's 10-day deadline regardless of where the car was purchased.
