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 a California dealer writes “No Problem Found,” “Cannot Duplicate,” or “Operating as Designed” on your repair order, it can be frustrating—especially if the defect keeps coming back. California Lemon Law firms like ZapLemon see these notes all the time. Below, we explain what those phrases mean under California law and how to document your visits so your warranty concerns are taken seriously. This article is for general information only and is not legal advice.
What “No Problem Found” Means Under CA Lemon Law
Dealerships often use “No Problem Found” when a technician can’t reproduce your complaint on a short test drive or during a brief inspection. It’s common with intermittent issues like a transmission shudder that happens once the car is hot, an infotainment screen that freezes after an hour, a hard-start when parked overnight, or a steering pull that shows up only at highway speeds. The note doesn’t mean you imagined the problem—it means the shop didn’t capture it during that visit.
Under California’s Song-Beverly Consumer Warranty Act (the California Lemon Law), your rights do not vanish because a dealer wrote “No Problem Found.” What matters is whether the vehicle has a defect covered by warranty that substantially impairs use, value, or safety—and whether the manufacturer had a reasonable number of opportunities to fix it. A visit where the dealer tries and fails to verify or repair the concern can still count as an attempt under many circumstances, even if the invoice says “cannot duplicate.”
Manufacturers sometimes argue that “No Problem Found” means there was no repair attempt, but lemon law claims are fact-specific. Patterns matter: repeat visits for the same issue, days out of service, and consistent complaints can show an ongoing problem that hasn’t been resolved. California law includes a presumption that may apply when problems persist within the warranty period and after multiple tries or extended time in the shop, but whether that presumption fits your situation requires a legal evaluation. A consultation with a California lemon law attorney can help you understand how these notes may affect your potential claim.
How to Document Dealer Visits and Repair Attempts
Be specific when describing the problem. Note times, conditions, and triggers: “Transmission shudders between 25–35 mph after 15 minutes of city driving,” “Screen goes black after using CarPlay for 30 minutes,” or “Vehicle drifts right at 65–70 mph on smooth freeway.” Ask the service advisor to include your exact words on the repair order, and request a test drive with a technician if the issue is intermittent. The more precisely you narrow the conditions, the better the odds the shop can reproduce it.
Save everything. Keep copies of all repair orders, invoices (even if marked “No Problem Found”), warranty repair codes, parts orders, towing receipts, and loaner or rental agreements. Maintain a simple log with dates, mileage in/out, and days your vehicle is unavailable. If safe, capture short videos or photos of warning lights, error messages, or the behavior you’re reporting. Document environmental factors (weather, fuel level, battery charge on EVs, cargo load) that might help a technician pinpoint the problem.
When the issue recurs, reference the prior visits and ask the advisor to link the concern to the same warranty complaint line. If the dealership road-tests the vehicle with you, note who was present and what happened. Ask whether the dealer checked for technical service bulletins (TSBs), software updates, or recalls, and request that any updates performed are listed on the invoice. If a manufacturer customer-care case is opened, write down the case number and any communications. Consistent, organized documentation helps show that the manufacturer had repeated opportunities to repair the vehicle and that the problem persists despite those opportunities.
“No Problem Found” is not the end of the road. Clear descriptions, thorough records, and persistence can help you demonstrate a pattern of unresolved defects under California Lemon Law.
