Start with the records. Repair orders, warranty documents, mileage, and days out of service are more useful than general assumptions about whether a vehicle qualifies.
When your car keeps going back to the shop for the same problem, it’s frustrating—and it can also be a sign that California’s lemon law might apply. At ZapLemon, our lemon law attorneys regularly hear from drivers who’ve done “everything right” but still can’t get a lasting fix. Below, we explain how California defines a failed repair and share practical documentation tips so you can better understand your options. This article is for general information only and isn’t legal advice; if you want guidance about your specific situation, please contact us for a consultation.
What Counts as a Failed Repair Under CA Law
Under California’s Song-Beverly Consumer Warranty Act (often called the California Lemon Law), a “failed repair” generally means a defect covered by your warranty persists after the manufacturer or its authorized dealer has had a reasonable number of chances to fix it. The issue must substantially impair the vehicle’s use, value, or safety. This applies to new vehicles and many used vehicles that are sold or leased with a manufacturer’s warranty still in effect.
California provides a helpful “presumption” period: within the first 18 months or 18,000 miles (whichever comes first), the law presumes the manufacturer had a reasonable number of attempts if certain thresholds are met. As a rule of thumb, that can mean 2 or more repair attempts for a defect that’s likely to cause death or serious bodily injury, 4 or more attempts for other recurring defects, or the vehicle being in the shop for repair for a total of more than 30 days. Even if you’re outside that presumption window, you may still have a claim; it just won’t be presumed and will depend on the full set of facts and records.
What does this look like in real life? Think of brakes that intermittently fail, a transmission that slips under normal driving, power steering that cuts out, an electrical system that drains the battery overnight, or a persistent check-engine light tied to drivability issues. Intermittent problems still count if they impair use, value, or safety—so mention any patterns you notice (e.g., “after highway driving,” “in hot weather,” or “after refueling”). Keep in mind that misuse, aftermarket modifications, or lack of maintenance may affect coverage, so always consult your warranty and ask questions at the service desk.
Documentation Tips to Strengthen Your Claim
Your paperwork is your proof. Each time you visit the dealer, ask for a detailed repair order (also called a work order or RO) that shows your exact complaint in your own words, the technician’s diagnosis, what parts were replaced, and the mileage in and out. Confirm that the dates reflect when you dropped off and picked up the vehicle—these dates help show total days out of service. Before leaving, read the RO; if the description is vague or incomplete, politely ask the service advisor to update it.
Keep a repair timeline. Create a simple log with dates, mileage, symptoms, weather/conditions, warning lights, and any photos or short videos that capture the problem. Save tow receipts, rental or loaner agreements, and any out-of-pocket expenses related to the defect. If the issue happens sporadically, note the frequency and triggers (“stalling after cold start,” “hesitates around 35 mph,” “burning smell after 20 minutes of driving”).
Preserve your communications with the dealer and manufacturer. Save emails, texts, and call notes—especially anything about “no trouble found,” backordered parts, or software updates. If your warranty requires notifying the manufacturer for a final repair attempt, follow those steps as outlined in your warranty booklet. Don’t clear diagnostic codes on your own, and avoid making modifications while the issue is being evaluated. If you’re unsure what to do next, a consultation with a lemon law attorney can help you understand your options before you escalate.
