California Car Dealers Face an Oct. 1 Deadline — Or Risk Lawsuits and Refunds

If you sell cars in California, the way you advertise, price, and close deals is about to change for good. The Combating Auto Retail Scams Act — SB 766 — takes effect October 1, 2026, and it rewrites the rules for nearly every step of the sales process, from the first ad a customer sees to the paperwork they sign at delivery. Dealers who haven't updated their systems by then are exposed to consumer lawsuits, DMV scrutiny, and forced refunds on deals already closed.

Gov. Gavin Newsom signed the bill in October 2025, giving dealerships roughly a year to prepare. For many independent and small franchise dealers, that runway is closing fast — and the law's first-contact requirement means the exposure starts the moment a customer sees an ad, not just when they sit down at the desk.

The Core Requirement: One "Total Price," Everywhere

The centerpiece of the CARS Act is a legally defined "total price" that must appear on every advertisement or listing referencing a specific vehicle — whether that's your own website, a listing on AutoTrader or Cars.com, a printed flyer, or a showroom display. That price has to reflect what a customer would actually pay, with three specific practices now banned:

• Concealed markups added after the advertised price
• Mandatory dealer add-ons bundled in but presented as if they were optional or separate
• Rebates baked into the advertised price that most shoppers wouldn't actually qualify for

In practice, that means the number a customer sees online has to be close to the number on the final bill of sale — not a lowball figure designed to get them in the door before the "market adjustment" and dealer fees get added back in.

The First-Contact Rule Is the Real Trap

Compliance specialists tracking the law point to one requirement as the biggest liability risk for dealers: initial customer contact — whether that's a phone call, a text, a chat widget response, or a walk-in greeting — has to include the required disclosures before the conversation moves to talking about a specific vehicle. A salesperson who dives straight into "let's talk numbers on that truck" before those disclosures happen is creating a compliance gap, even if the eventual paperwork is clean.

That puts pressure on training, not just paperwork. Every salesperson, every lead-response text template, and every chatbot script now needs to route through the disclosure requirement before pricing talk begins.

A New Three-Day Cancellation Window

The law also hands buyers new leverage after the sale. For used vehicles priced at $50,000 or less, customers now get a mandatory three-day window to cancel the deal. For a dealer, that means a completed sale isn't necessarily final — inventory that's already been reconditioned, detailed, and delivered can come back, and the transaction has to be unwound within that window if the buyer exercises the right.

What Records You Now Have to Keep

The Act also raises the bar on documentation. Dealers must retain advertisements and price communications — and, depending on which compliance guidance you follow, potentially all customer communications — for at least two years, with some compliance vendors recommending four years of automatic capture to be safe. That covers digital ads, print materials, text and email threads with customers, and in-store pricing sheets. If a dispute arises months after a sale, the burden falls on the dealer to produce the record showing what was actually disclosed and when.

What to Do Before October 1

1. Rewrite your advertising and listing templates now

Every channel — your website, third-party marketplace listings, printed materials, and in-store signage — needs to show the same total price, calculated the same way. Inconsistency between platforms is one of the easiest violations for a regulator or plaintiff's attorney to spot, since it's a simple side-by-side comparison.

2. Rebuild your first-contact scripts

Whatever generates your first response to a lead — a human salesperson, a CRM auto-reply, or a chat tool — needs the required disclosures built in before pricing discussion starts. This is as much a sales-process change as a legal one.

3. Get written consent for every add-on

Extended warranties, paint protection, VIN etching, and similar products now require express written consent and separate, transparent pricing. If your F&I process still bundles these by default and lets customers opt out, that workflow needs to flip to opt-in.

4. Build the three-day cancellation window into your operations

Reconditioning, financing paperwork, and delivery timelines may need adjusting so a canceled deal doesn't leave you holding a vehicle that's already been altered in ways that are hard to unwind.

5. Revisit your business structure and coverage

A law with new consumer lawsuit exposure is a good trigger to have your attorney or accountant review whether your dealership's entity structure and business insurance — particularly errors-and-omissions or general liability coverage — are set up to handle the increased legal risk. If you're still operating without a formal LLC shielding your personal assets, this is the kind of regulatory shift that makes that gap expensive.

The Bottom Line

The CARS Act isn't a minor paperwork update — it touches advertising, sales scripts, F&I add-ons, record-keeping, and post-sale rights all at once. For a large franchise store with a compliance department, that's a project. For a small independent lot running on a handful of staff and a shared listing template, it's a much heavier lift with the same October 1 deadline. Dealers who wait until the effective date to start adjusting are likely to be mid-transition exactly when the first customer complaint tests the new rules.
