Lemon law arbitration or a lawsuit: which path fits your case?

When a manufacturer cannot fix your vehicle, someone usually mentions arbitration. Customer service may point you to BBB AUTO LINE. Your warranty booklet may describe a "dispute settlement program." Your dealer contract may have an arbitration clause in fine print. These are three different things, and in California they have very different effects on your rights. Choosing between lemon law arbitration and a lawsuit is easier once you know which one you are looking at.

This guide explains the manufacturer dispute programs certified by the State of California, what happens to the lemon law presumption and civil penalties if you use one or skip it, how binding arbitration clauses in dealer contracts fit in after a 2025 California Supreme Court decision, and how to decide. It is general information as of October 2026, not legal advice.

Three kinds of "arbitration" you may hear about

• A manufacturer's dispute program. An informal, free process run by an outside organization such as BBB AUTO LINE. In California, a program that meets the state's standards is certified by the Department of Consumer Affairs. The decision binds the manufacturer only if you accept it. You are not bound.
• A binding arbitration clause. A term in a contract, often the dealer's retail installment sales contract, that says disputes go to a private arbitrator instead of a court. This is a different question, covered below.
• Fee arbitration under the 2025 procedures. For manufacturers that opted in to AB 1755 and SB 26, disputes over attorney's fees after a pre-suit offer go to binding arbitration. Our AB 1755 guide covers that narrow step.

Which programs are state-certified, and for which brands

The Department of Consumer Affairs' Arbitration Certification Program lists three certified programs as of October 2026:

The list changes, so confirm it on the DCA page before you file. If your manufacturer has no certified program, the DCA says you can go to court or try mediation through the New Motor Vehicle Board at (916) 445-1888.

How a state-certified program works

According to the DCA, certified arbitration is free, and decisions "usually come within 40 days" after the program gets your application. A federal rule sets the same 40-day target: the Federal Trade Commission's warranty guide says a qualifying program must decide within 40 days of receiving notice of a dispute and must issue decisions that are not binding on the consumer.

California adds its own requirements in Civil Code § 1793.22(d). Among them, a qualified program must:

• issue decisions that are "binding on the manufacturer if the buyer elects to accept the decision";
• give the manufacturer a deadline of no more than 30 days after you accept to carry the decision out;
• be able to order a replacement (if you consent) or restitution;
• provide, on request, an inspection and written report by an independent automotive expert at no cost to you;
• keep the manufacturer from taking part in the decision unless you can take part equally; and
• be certified by the Department of Consumer Affairs.

The same subdivision says the program does not have to award punitive damages, multiple damages, attorney's fees, or consequential damages beyond those in Civil Code § 1794(a) and (b). That is the main trade-off: a program can order a buyback, but it is not built to award the civil penalty or your lawyer's fees.

Do you have to arbitrate before suing?

No. Nothing in California's lemon law requires you to use a manufacturer's program before filing a lawsuit. The DCA describes arbitration as optional: the manufacturer may offer to settle, and you decide whether to accept, go to arbitration, or pursue other options. But skipping a certified program has two consequences worth understanding.

1. The presumption waits until you have used the program

The Tanner Act presumption in § 1793.22(b) says a manufacturer has had a reasonable number of repair attempts if, within 18 months or 18,000 miles, a serious safety defect was subject to repair two or more times, the same defect four or more times, or the vehicle was out of service more than 30 days. Under § 1793.22(c), if the manufacturer has a qualified program and you received timely written notice of it, "the presumption in subdivision (b) may not be asserted by the buyer until after the buyer has initially resorted" to the program. If you are dissatisfied with the decision, you can then assert the presumption in court.

The presumption is a shortcut, not a requirement. You can still prove in court that the manufacturer had a reasonable number of attempts without it, and many claims fall outside the 18-month window anyway. Our guide on how many repair attempts it takes explains how that proof works.

2. One of the civil penalties is off the table, but not the other

Civil Code § 1794 has two civil penalty routes, each up to two times your actual damages:

• Section 1794(c) allows a penalty when the manufacturer's failure to comply was willful.
• Section 1794(e)(1) allows a penalty for a violation of the new-vehicle buyback rule without a willfulness finding, but § 1794(e)(2) says that if the manufacturer maintains a qualified dispute program that substantially complies with § 1793.22, it "shall not be liable for any civil penalty pursuant to this subdivision." That penalty also requires a written notice to the manufacturer under § 1794(e)(3).

So a manufacturer with a certified program avoids the (e) penalty whether or not you use the program. The willful penalty under § 1794(c) remains available in court. For manufacturers that opted in to the 2025 procedures, a separate pre-suit notice under Code of Civil Procedure § 871.24 controls whether you can seek a civil penalty at all; see our AB 1755 guide.

What happens to your deadline

Section 1793.22(c) extends any period of limitation under federal or California law for the time a complaint is pending with a third-party program. For opted-in manufacturers, Code of Civil Procedure § 871.21 also pauses the one-year-after-warranty deadline while a qualified program handles the claim.

What the decision is worth later

If you reject the decision and sue, § 1793.22(c) makes the program's findings and decision "admissible in evidence in the action without further foundation." So prepare a program claim as carefully as a lawsuit.

Program or lawsuit: a side-by-side

How often do people use these programs? The DCA's most recent biennial report found in our research, covering 2021 and 2022, reported 2,201 total disputes across the three certified programs in 2022: 1,778 at BBB AUTO LINE, 409 at CDSP and 14 at CAP-Motors, according to the DCA report published in June 2024. For comparison, the Assembly Judiciary Committee's analysis of AB 1755 reported 14,892 lemon law filings in California courts that year.

Arbitration clauses in dealer sales contracts

Many California dealer financing contracts include a clause requiring arbitration. Manufacturers argued they could use the dealer's clause, though they did not sign the contract, under a doctrine called equitable estoppel.

The California Supreme Court rejected that argument in the Ford Motor Warranty Cases in July 2025. In a unanimous opinion, the court held that Ford could not compel arbitration of buyers' lemon law and fraud claims based on the dealers' sales contracts, because the claims arose from the manufacturer's warranty and statutory duties and were "not intimately founded in or intertwined with the sales contracts," as the Berkeley Center for Consumer Law & Economic Justice summarized. Our Ford lemon law guide lists the case among reported California rulings.

Two limits matter. The ruling addressed a manufacturer trying to use a dealer's contract. A claim against the dealer itself, which did sign the contract, can raise a different question. And some manufacturers sell directly to buyers under their own purchase agreements, which may contain their own arbitration terms. If you signed anything with an arbitration clause, have a lawyer read it before you file anywhere.

Federal law: Magnuson-Moss and "prior resort"

The federal Magnuson-Moss Warranty Act allows a manufacturer to require, in its written warranty, that you try its informal dispute program before suing under that federal Act. According to the FTC, such a program must follow the FTC's Dispute Resolution Rule, and its decisions cannot bind the consumer. This matters most when the federal Act is a main claim, as it can be for used cars.

How to decide

1. Check for a binding arbitration clause in every document you signed. It changes the analysis more than anything else.
2. Check whether your manufacturer has a certified program on the DCA list, and whether your warranty booklet disclosed it.
3. Look at your repair history. A short, clean record within 18 months may do well in a program. A long, disputed history, or evidence the manufacturer ignored clear duties, usually belongs in court, where a civil penalty and fees are available.
4. Look at your deadline. For opted-in manufacturers it can be one year after the warranty expires. For others it is generally four years under the Commercial Code's warranty statute of limitations, and tolling rules can apply. Either way, call promptly.
