The California CARS Act (SB 766) takes effect October 1, 2026. And while the statute covers a lot of ground, one requirement should stop every dealer in the state: the total price has to be disclosed in the first written communication to a potential purchaser.

Read that again and think about what your first written communication actually is.

The price lives wherever your systems say it does

In the showroom, the price is on the windshield. Over text, email, and chat, the price is whatever the system sending the message says it is.

That’s the whole problem. Your customers aren’t standing on your lot when the conversation starts. They’re texting at 11 p.m., clicking a VDP from a paid ad, calling the service line on a lunch break, replying to an email three days after they opened it. One of those is your first written communication. Probably an automated one.

A compliant website and a compliant window sticker don’t help you if the number a customer gets over SMS came from a different source of truth. Consistency across channels isn’t a nice-to-have anymore. It’s the requirement.

The Act is broader than pricing

Worth being clear: disclosure is one piece. The CARS Act also creates a mandatory three-day right to return for used vehicles priced at $50,000 or less, with a required document titled “3-Day Right to Cancel Used Car Purchase or Lease”, and it prohibits misrepresentations across costs and terms, add-on products, credit applications, and vehicle availability at the advertised total price.

No technology platform addresses all of that. Cancellation paperwork, F&I product substantiation, and staff training are process and legal work. What technology can address is the conversation layer: what gets said about price, in writing, at first contact, and whether you can produce it later.

Where stores tend to get caught

Four patterns show up again and again, and none of them are about bad intent:

Multiple sources of truth. The price on the VDP, the price in the CRM template, and the price a BDC rep quotes over text all trace back to different places. One goes stale and nobody notices until a customer does.

Channel gaps. The website gets a compliance review. Email templates get a compliance review. Outbound SMS often doesn’t, even though it’s where the highest-velocity pricing conversations happen, and often where the first written communication lands.

Store-by-store drift. A group rolls out one disclosure standard, then individual franchises adjust it locally. Twelve stores, nine versions.

No retrieval path. The first written communication containing the price disclosure has to be retained for at least two years and made available to the consumer on written demand. If something gets questioned in month eighteen, can you produce the actual message? Worth confirming that every message your platform sends is logged and auditable.

Getting ready: a four-item checklist

Whatever systems you run, the prep work is roughly the same. Work through these with your vendors and your own legal counsel:

1. Build a total price field. Make sure your inventory feed or website carries a total price constructed the way the statute requires for your operation, including pre-installed add-ons and market adjustments. This is the foundation. Everything downstream reads from it.
2. Verify ingestion end to end. Confirm that every system touching a customer, including your chat, SMS, and email platforms, actually pulls from that field and maps it correctly. Test it, don’t assume it. Then set a recurring audit so a feed change six months from now doesn’t quietly break what you just fixed.
3. Finalize your disclosure language. Write it once, then check that it’s configured in every channel and at every store. If your platform supports store-level settings, set them deliberately rather than inheriting defaults.
4. Review with counsel. Walk your total price construction, your disclosure language, and your retention approach through your attorney. The liability under this law sits with the dealership. The Act already makes you keep two years of records, so add one more: if a disclosure gets challenged in month eighteen, “our counsel reviewed and approved this approach” is a far better position than “we thought we were fine.”

What to ask your technology vendors

If a platform is talking to your customers about price, it’s part of your compliance picture. Five questions worth asking every vendor in your stack:

• Where does the price in a customer-facing message come from, and how often does it refresh?
• Can disclosure language be configured per store, or is it one global setting?
• Does that configuration apply to SMS and email, or only to the website?
• What keeps the AI or template from answering a pricing question it shouldn’t?
• How long are conversation records retained, and how quickly can you produce a specific message?

Every vague answer is a gap you inherit, because the disclosure goes out under your name, not theirs.

How Impel approaches it

Impel’s AI Operating System was built with regulatory awareness in the architecture, not bolted on after the fact. 

When a vehicle comes up in conversation, Impel surfaces your total price, pulled from your website or live inventory feed, with disclosure language configured to your specifications. Pricing behavior and disclosure language are set at the store level, including a dealer-defined Pricing Disclosure field for email and SMS. Our models run on automotive-specific guardrails designed to keep conversations on topic and reduce the risk of inaccurate responses, with particular attention to pricing, financing, credit, deal structure, and trade-in. And Impel retains conversation records for two years, available on request.

The platform carries and discloses the pricing and policy information you provide. That’s the division of labor, and it’s worth being clear about it.

California is first, not last

The federal picture makes this point better than we could. When the Fifth Circuit vacated the FTC’s nationwide CARS Rule on January 27, 2025, a rule that never actually took effect, many dealers assumed the threat of heavy-handed pricing regulation had quietly disappeared. That relief proved premature. California picked up the framework, added strict used-car parameters, and passed SB 766.

Federal rulemaking stalled. State legislatures didn’t. And many of the FTC’s other advertising expectations were already required under California law, which is the pattern worth watching: the obligations arrive whether or not a single national rule survives.

California is the first state to put this into law. It won’t be the last. The stores in the best shape when the next one passes will be the ones running on a platform where new disclosure rules are a configuration change, not a fire drill.

Frequently asked questions

When does the California CARS Act take effect?	The California CARS Act (SB 766) takes effect October 1, 2026. Governor Newsom signed it on October 6, 2025.
What does the CARS Act require dealers to disclose?	Dealers must disclose a vehicle’s price in any advertisement referencing a specific vehicle, in any advertisement representing a monetary amount or financing term, in the first written communication to a potential purchaser, and must disclose how any down payment or trade-in will be applied. The disclosure requirements are codified at Cal. Civ. Code § 1784.41 and § 1784.42.
Does the CARS Act apply to AI chat and SMS conversations?	Any channel where you discuss price with a customer is part of your disclosure picture, and an automated text or email is often the first written communication a customer receives. Ask each vendor in your stack where its pricing data comes from and whether disclosure language is configurable for SMS and email, not just the website.
What has to be included in the total price?	Pre-installed add-ons and dealer-applied market adjustments must be included. The document processing charge remains a separately disclosed item excluded from the total price. Confirm your construction with counsel.
How long do records have to be retained?	Two years from the date of record creation, covering advertisements, communications, contracts, cancellation requests, and written complaints. The first written communication containing the price disclosure must be available to the consumer on written demand.
Is there a right to cancel under the CARS Act?	Yes. Buyers of used vehicles priced at $50,000 or less have three business days to return the vehicle, documented with the required statutory language. The option must be exercised within 400 miles of purchase, and if the vehicle is driven more than 250 miles the dealer may charge $1 per mile, capped at $150.
What should a dealership do to prepare for the CARS Act?	Build a total price field constructed per the statute, verify every customer-facing system ingests and maps it correctly, finalize and configure disclosure language across every channel and store, and review your approach with qualified legal counsel.
