Repeated service appointments with “No Trouble Found” on the repair order can be maddening—especially when your car keeps stalling, shuddering, or throwing intermittent warning lights. If you’re in California, you may still have protections under the state’s lemon law even when the dealer can’t “duplicate” the problem. This article explains, in plain language, how the law treats repeated visits without a diagnosis and what practical steps you can take to document your situation and explore your options with a professional.
Repeated Dealer Visits With No Diagnosis? Your Rights
When a vehicle is under the manufacturer’s warranty, California’s Song-Beverly Consumer Warranty Act requires the manufacturer (through its authorized dealers) to repair defects that substantially impair the use, value, or safety of the car. The law doesn’t require you to know the exact cause of the problem—only that you present the vehicle for repair while the warranty is in effect. Intermittent problems are common with modern vehicles, and “unable to verify concern” does not erase the fact that you reported a real issue.
Importantly, many consumers don’t realize that repair visits still count even if the dealer writes “No Trouble Found.” Your service history shows that you gave the manufacturer reasonable opportunities to fix the defect. Time out of service matters too—days your car sits at the shop awaiting diagnosis or parts can add up, regardless of whether a technician pinpoints the fault. Safety-related issues (like sudden loss of power, braking inconsistencies, or airbag warnings) can elevate the urgency and reduce how many attempts are considered “reasonable.”
You can protect yourself by documenting every visit. Always request a printed repair order that lists your symptoms in your own words (“customer states: vehicle stalls when slowing to a stop,” “transmission shudders at 25–35 mph,” or “screen reboots randomly”). Bring photos or short videos capturing the issue, note dates, mileage, and weather conditions, and ask whether any Technical Service Bulletins (TSBs) or software updates apply. If the problem persists, consider asking the dealer to open a case with the manufacturer and request a field technician evaluation.
California Lemon Law When Shops Can’t Diagnose It
California’s lemon law can apply when a defect is covered by warranty and the manufacturer cannot repair it after a reasonable number of attempts, or when the vehicle is out of service for an extended period for warranty repairs. A “reasonable number” isn’t a fixed number and depends on the severity and safety risk of the issue. Even when the work order says “no fault found,” those visits typically count as repair attempts because you presented the vehicle for the same recurring problem.
If your issue is intermittent—like a transmission that occasionally slips, a power steering assist that cuts out randomly, or a camera system that fails unpredictably—clear records are crucial. Keep every repair order, parts list, and software update note. When possible, capture the symptom on video, and be specific about conditions (speed, temperature, incline, fuel level). Ask the service advisor to check for TSBs or known concerns and to include your detailed description on each repair order. Used and certified pre-owned vehicles may also be protected if the defect occurs within the applicable warranty period.
If the problem continues after multiple visits or extended time in the shop, you can explore options such as a manufacturer repurchase (buyback), replacement, or a cash-and-keep settlement—outcomes depend on the facts and the law. Some programs offer arbitration, and, in many cases, California law allows consumers who prevail to seek recovery of reasonable attorney’s fees from the manufacturer. Deadlines can apply, so it can be helpful to speak with a California lemon law attorney who can evaluate your records and explain your options.
