Lemon Lawyers Explain: Arbitration Panel Decision Factors

Arbitration can feel like a black box when your vehicle keeps breaking down and you’re trying to figure out what comes next. At ZapLemon, we help Californians understand how lemon law arbitration works and what arbitration panels typically look at when deciding a case. Below, our lemon lawyers explain key decision factors in plain English so you can prepare, protect your rights, and make informed choices about your next steps.

What California Lemon Arbitration Panels Consider

Arbitration panels start by asking a basic question: Is there a defect that substantially impairs the vehicle’s use, value, or safety, and did it arise during the manufacturer’s warranty? Under California’s Song-Beverly Consumer Warranty Act (the “lemon law”), panels commonly examine whether the manufacturer—or its authorized dealer—had a reasonable number of chances to fix the issue. They also look at time in the shop, the severity of the problem (especially safety risks like stalling, brake failures, or airbag warnings), and whether the defect is repeatable.

Evidence is crucial. Panels weigh repair orders, dealer notes, diagnostic codes, warranty records, recall and technical service bulletin (TSB) information, and your own documentation, such as photos, videos, and a log of dates, mileage, and symptoms. They may consider test-drive results, whether the dealer could duplicate the concern, and whether you consistently reported the same problem. They also check for red flags like modifications, misuse, or skipped maintenance that could affect coverage.

California’s lemon law includes a “presumption” that can help consumers within the first 18 months or 18,000 miles if certain thresholds are met—such as two or more repair attempts for a defect that could cause death or serious injury, four or more attempts for the same non-safety defect, or 30 or more cumulative days out of service. Panels often reference these benchmarks, but they are not the only path to relief. Every case is fact-specific. Arbitration decisions are typically not a court judgment, and in many California programs they are not binding on the consumer—but program rules vary, so always review them before you opt in.

How Panels Weigh Repair Attempts and Warranty

When it comes to repair attempts, panels look beyond the raw count. They examine whether the attempts were for the same issue, how serious the problem is, and whether the dealer had a fair chance to diagnose and fix it. “Could not duplicate” visits and software updates can still count as attempts if they address the same recurring defect—think repeated transmission shudder, EV charging failures, or an infotainment system that reboots and disables the backup camera.

Days out of service matter, too. A vehicle spending 30 or more cumulative days in the shop—whether during one long visit or across multiple visits—can support a claim that the manufacturer had a reasonable chance to fix the problem. Panels also consider timing: Was the issue first reported during the warranty period? Did you bring the vehicle to an authorized dealer? Did the problem return after a “fix”? A pattern of recurring symptoms after multiple dealer visits can weigh in the consumer’s favor.

Warranty coverage is central. Panels typically ask whether the defect appeared and was reported while the express warranty was active, and whether any exclusions apply. Aftermarket modifications, racing, off-road misuse, or neglecting basic maintenance can undermine coverage. Certified pre-owned and extended warranties can be relevant, but they don’t always cover the same components as the original warranty—EV battery warranties, for example, may have special terms. Keep your warranty booklet handy, and be prepared to show that you followed the maintenance schedule and used authorized repair channels.
