Car buyers often assume a new federal rule changes what happens at the finance desk the next day. The FTC's Combating Auto Retail Scams Rule, known as the CARS Rule, was meant to target deceptive pricing and unwanted add-on charges. It never became enforceable. Here is what that means for a buyer sitting down to sign loan papers.

What happened to the CARS Rule

According to the industry sources reviewed for this piece, the U.S. Court of Appeals for the Fifth Circuit set the rule aside on January 27, 2025. The same sources say the FTC withdrew it on February 12, 2026. Neither date was checked against a court or FTC document, so confirm them on the FTC website before citing them. Either way, no dealer was ever required to follow the rule's specific provisions.

The reported basis for the decision was procedural, meaning how the rule was issued, not whether its consumer protections were sound. That distinction matters. A rule thrown out on procedure is not a finding that deceptive sales practices are acceptable.

In practice, a buyer cannot point to the CARS Rule during a loan discussion. Other federal and state laws do the work.

Protections that still apply

Dealers remain subject to Section 5 of the Federal Trade Commission Act, which bars unfair or deceptive acts or practices. The sources indicate the court ruling did not reduce the FTC's authority to bring cases under that law. They also indicate it did not limit state regulators.

State attorneys general can act under their own consumer protection statutes. Trade commentary from Fullpath, a dealer software vendor, says pricing transparency, financing disclosure and truthful advertising duties have existed for decades. That is one vendor's view, so treat it as context rather than a legal reference.

The FTC also posted Price Transparency FAQs for auto dealers, dated September 2026 on its site. The page reviewed here showed only the title and date, so the content of the FAQs is not described in this article.

Conduct regulators target

The concerns behind the CARS Rule did not disappear. The sources list several practices that draw regulator attention:

  • Adding fees or products without the buyer's approval and clear disclosure.
  • Bait-and-switch advertising.
  • Selling add-ons that give the buyer little or no benefit.
  • Misstating vehicle prices or financing terms.
  • Advertising vehicles that are not available at the promoted price.

One source reports that the FTC and the Illinois Attorney General reached a $20 million settlement in late 2024 with a dealership group accused of advertising low prices while requiring extra purchases. The source text was cut off, so the full terms are not confirmed here. The same source says nineteen state attorneys general backed the FTC's position on the rule, citing complaints about hidden fees and forced add-ons.

State bills and what to watch

State legislatures are where new requirements are most likely to appear. California Senate Bill 766, introduced in early 2025, would give buyers a three-day right to cancel a used vehicle purchase priced at or below $50,000, with a return allowed within three days or 400 miles. One source gives an October 1, 2026 effective date. The sources do not confirm whether the bill passed, so check California's legislative records before relying on it.

Steps to take before you sign

The sources do not offer a buyer checklist, so these steps are general good practice, not claims drawn from them. Start with the price. Ask for an itemized out-the-door price in writing, listing the vehicle price, taxes, government fees, dealer fees and every add-on.

Next, decline optional products you do not want. Service contracts, accessories and insurance packages should be your choice, and each one should appear as its own line item.

Then read the loan disclosure. Federal Truth in Lending rules call for the annual percentage rate and the total finance charge to be stated in the credit paperwork. Compare those figures to what you were quoted. If they differ, stop and ask why before signing.

  1. Get the itemized price in writing.
  2. Strike add-ons you did not ask for.
  3. Check the APR and finance charge against the quote.
  4. Keep copies of ads, texts and signed documents.

If something goes wrong, you can report it to the FTC at ReportFraud.ftc.gov, to your state attorney general's consumer protection office, or to the Consumer Financial Protection Bureau. Bring your documents. A saved ad showing a price the dealer later refused to honor is the kind of detail that helps.
