Lemon Law Attorneys Explain: Arbitration Packets

If you’re dealing with a stubborn car defect in California, you’ll eventually hear about manufacturer “arbitration” and the packet of documents you’re expected to submit. Think of the arbitration packet as the story of your vehicle told through paperwork: how you bought it, what went wrong, and what the dealership or manufacturer did to fix it. Below, ZapLemon’s lemon law team explains, in plain language, what typically goes into a California lemon law arbitration packet and how to put yours together so an arbitrator can easily understand your case. This article is for general information only and isn’t legal advice.

What’s Inside a California Lemon Law Arbitration Packet

In California, arbitration is often run through a manufacturer-sponsored program (for example, programs similar to BBB AUTO LINE or brand-specific panels). While you are not required to arbitrate before pursuing your rights under the Song-Beverly Consumer Warranty Act (the California lemon law), some consumers try arbitration first because it can be quicker and free. Your arbitration packet is the complete file the arbitrator will review—so clarity, completeness, and organization matter.

At its core, the packet usually includes: your purchase or lease agreement, any warranty booklet or service contract, vehicle registration, and proof of ownership or lease. Just as important are the repair orders and invoices for each visit to the dealership, showing the date, mileage, your complaint (“customer states”), the cause found, and the correction attempted. Add communications with the dealer or manufacturer—emails, texts, photos, videos of the defect, case numbers, recall notices, and any written “we can’t replicate” responses—and include towing or rental receipts tied to the repair visits.

Many programs also invite a brief personal statement: a summary of the defect, how it affects safety or use, and how many times repairs were attempted. A timeline that lists each repair visit in date order is helpful, as are records of diagnostic codes if you received them. You may see references to a “mileage offset” in California (often calculated using a 120,000-mile divisor); if the program asks for numbers you don’t know, it’s okay to leave them blank and focus on accurate documents. Remember to omit or redact sensitive information like your Social Security number. The goal is to present a factual, easy-to-follow record of ongoing problems under the original warranty.

How to Prepare and Organize Your Packet for Review

Start by gathering every document related to the vehicle: sales or lease paperwork, warranty booklets, service records, emails with the service advisor, and photos or videos of the symptoms. Create a one-page cover sheet with your name, contact information, VIN, make and model, and the arbitration case number. Then write a short, neutral summary (five to eight sentences) describing when the problems began, how often the vehicle has been in for repairs, and how the issue affects safety, value, or daily use—for example, stalling at intersections, repeated check-engine lights, hard shifting, brake pulsation, or electrical shutdowns.

Next, build a simple chronology. List each repair visit with its date, mileage, and concern-cause-correction notes copied from the repair orders. If you experienced the same defect multiple times—say, transmission shuddering at 35–45 mph—make that pattern obvious by describing each attempt consistently. Place the repair orders directly behind the chronology, in the same order, and make sure every page is legible. If a page is hard to read, add a small note: “Copy is faint; original was light.”

Finish by creating sections and page numbers: Section A (Vehicle and Warranty), Section B (Chronology), Section C (Repair Orders), Section D (Communications), Section E (Expenses), Section F (Photos/Videos). Add a simple index at the front so the arbitrator can find things fast. Scan the full packet into a single PDF, name it clearly (e.g., “Smith_VIN1234_ArbPacket.pdf”), and keep a backup. Check the program’s deadline and submission instructions; some require online upload, others want hard copies. Don’t include private, attorney-client communications or make promises about outcomes. If you’re missing repair records, request printouts from the dealership’s service department or the manufacturer’s customer care—dealers can often reprint your warranty repair history.
