Lemon Law Attorneys Discuss: Preparing for Manufacturer Arbitration

Manufacturer arbitration can feel intimidating, especially when you’re already frustrated with a vehicle that keeps breaking down. At ZapLemon, our lemon law attorneys regularly guide California consumers through the process so they understand what to expect and how to present their story clearly. Below, we explain how California lemon law manufacturer arbitration works and what to gather so you’re prepared for your hearing—strictly for informational purposes.

How California Lemon Law Manufacturer Arbitration Works

In California, many automakers participate in state-certified manufacturer arbitration programs for warranty disputes under the Song-Beverly Consumer Warranty Act (the “California Lemon Law”). These programs—monitored by the state’s Arbitration Certification Program (ACP)—are typically free to consumers and are designed to resolve disputes faster than court. Importantly, you are generally not required to use arbitration before filing a lawsuit in California, but some consumers choose it because it can be quicker and less formal.

Arbitration is not a courtroom trial. A neutral arbitrator reviews your documents, listens to both sides (often by phone or video), and issues a written decision. If you prevail and accept the decision, the manufacturer is usually bound to follow it. If you lose, you typically aren’t bound and can still consult an attorney about your options, including possibly filing a lawsuit, subject to any applicable deadlines.

The arbitrator can consider remedies like repurchase (“buyback”), replacement, or additional repairs, as well as certain incidental expenses authorized by the program, such as towing or rental car costs. Outcomes depend on the facts, including whether the defect is covered by warranty, how many repair attempts were made, and how long the vehicle was out of service. California law also uses a mileage offset when calculating a buyback; the deduction accounts for the miles driven before the first repair attempt for the defect at issue.

What to Gather Before Your Arbitration Hearing

Strong documentation is the foundation of a clear, persuasive presentation. Gather all repair orders, work orders, and invoices for each visit—including dates, mileage, the complaint you reported, and what the dealer did. Add supporting paperwork such as your purchase or lease agreement, warranty booklet, owner’s manual, vehicle registration, odometer statements, and any relevant recall or Technical Service Bulletin (TSB) notices.

Create a simple timeline of the problem: when it started, every repair attempt, how the vehicle performed afterward, and any safety concerns or breakdowns. Include photos or short videos if they help show the defect (for example, dashboard warning lights, leaking fluid, or intermittent screen blackouts). Keep receipts for out-of-pocket expenses like towing, rideshares, hotels, or rental cars tied to the defect—arbitration programs sometimes consider these incidental costs.

Before the hearing, practice a concise summary: what the defect is, how it affects safety or use, the repair history, and what remedy you’re requesting. Be consistent with your documents, avoid speculation, and stick to facts in plain language. Finally, check your warranty coverage and any deadlines, and consider speaking with a lemon law attorney to understand your rights and strategy for presenting your case; a consultation can help you avoid common pitfalls.
