Do you support mandatory three-day return policies for used vehicle purchases?

Starting October 1, 2026, California will implement the Combating Auto Retail Scams Act, a new law requiring transparent vehicle pricing and clearer disclosure of optional features. The mandate covers light-duty vehicles under 10,000 pounds, including both new and used inventory.

Why it matters

The legislation aims to eliminate hidden fees and deceptive sales tactics that have historically complicated the car-buying process for consumers. By mandating full price transparency, the state seeks to standardize financial expectations across all dealership transactions.

The law applies to light-duty vehicles weighing less than 10,000 pounds and includes a mandatory 3-day right-to-cancel period for used vehicle transactions under $50,000.

The players

Gavin Newsom

He is the current Governor of California who signed the Combating Auto Retail Scams Act into law.

The details

Dealers must now explicitly identify which add-ons are optional and are prohibited from charging for items that provide no benefit to the buyer. While the law grants consumers the right to return used vehicles, dealers retain the ability to charge a restocking fee for processed returns.

Governor Gavin Newsom signed the legislation into law in October 2025.
The new regulatory requirements will take effect on October 1, 2026.

Roadmap

This legislation reflects a growing trend of state-level intervention to modernize retail protections in an increasingly complex automotive market. By formalizing disclosure requirements, California is shifting the balance of power from dealership add-on models toward standardized consumer rights.

Buyers will benefit from mandatory price transparency that prevents hidden costs during the negotiation process. Additionally, the new 3-day return policy for used cars provides a significant financial safety net for those purchasing vehicles under the $50,000 threshold.

The takeaway

Consumers should review their purchase contracts closely to differentiate between mandatory and optional add-on features before the new law takes effect. Maintaining organized documentation of all transaction terms will be essential for utilizing the new return protections after October 2026.
