What to Know About Lemon Law Arbitration Hearings

If you’re dealing with repeat car problems and endless trips to the dealer, you may have heard about “lemon law arbitration.” In California, arbitration is a faster, more informal way to resolve warranty disputes with your vehicle’s manufacturer. This article explains how California lemon law arbitration works and what to bring and expect at your hearing, so you can feel prepared and informed before you take the next step.

California Lemon Law Arbitration: How It Works

California’s lemon law (the Song-Beverly Consumer Warranty Act) protects consumers when a warrantied vehicle has substantial defects that the manufacturer or its dealers can’t fix after a reasonable number of attempts. Arbitration is one way to resolve these disputes without going to court. Many manufacturers offer programs that are certified by the California Department of Consumer Affairs’ Arbitration Certification Program (ACP). These programs are designed to be free to consumers, faster than litigation, and conducted by a neutral arbitrator.

The process typically starts when you file a claim with the manufacturer’s arbitration program, explaining the problems with your vehicle, the repair history, and what outcome you’re seeking (such as a repurchase, replacement, or reimbursement for certain expenses). The manufacturer responds, the program schedules a hearing (often by phone or video), and a neutral arbitrator hears both sides. After the hearing, the arbitrator issues a written decision. If it’s a state-certified program, the manufacturer is usually bound if you accept the decision; you, as the consumer, can decline the decision and consider other options.

Arbitration can be a good fit if you want a quicker answer and minimal red tape, but it has limits. The rules of evidence are relaxed, there’s no formal discovery, and awards may vary between programs. Arbitration is generally voluntary in California—you are not required to arbitrate before filing a lawsuit—but participating in a certified program can sometimes help clarify the issues or prompt a resolution. No matter what path you choose, keep thorough repair records, confirm your warranty coverage, and know that each case turns on its specific facts.

What to Bring and Expect at Your Arbitration Hearing

Bring organized, easy-to-read proof of your vehicle’s problems and your repair efforts. That usually includes: your purchase or lease agreement, warranty booklet, current registration, all repair orders and invoices, repair estimates, and any towing, rental car, or rideshare receipts. Photos or short videos that show the issue (for example, dashboard warning lights, infotainment reboots, stalling, or transmission shudder) can be helpful. Print out any emails or messages with the dealer or manufacturer and prepare a simple timeline showing dates, mileage, and what happened at each visit.

Most hearings are informal and last about an hour, sometimes longer for complex cases. The arbitrator will confirm everyone’s roles, ask you to explain the problem, and may ask follow-up questions. You’ll have a chance to present your documents and describe how the defect affects safety, use, or value—such as brake failures, power loss, repeated battery drains, water leaks, or air-conditioning that won’t cool. The manufacturer’s representative will present their side as well. You can attend by phone or video in many programs, and you can request an interpreter or reasonable accommodations if needed.

After the hearing, you’ll receive the arbitrator’s written decision by mail or email. If the decision offers a remedy—like a repurchase (buyback), a replacement vehicle, or reimbursement of certain costs—read it carefully, including how mileage offsets and incidental expenses are handled. Pay attention to any deadlines for accepting or rejecting the decision. If the result doesn’t resolve your concerns, or if you have questions about next steps, consider speaking with a lemon law attorney to understand your options.
