Auto Lemon Law California: Days in the Shop and the California Lemon Law

When your car keeps going back to the dealership, the “days in the shop” can quickly add up—and in California, those days matter. The California Lemon Law (part of the Song-Beverly Consumer Warranty Act) looks at how long a vehicle is out of service for warranty repairs, along with how many repair attempts have been made, to determine whether the manufacturer may owe a refund or replacement. This article explains how “days in the shop” are counted under California law, and how to track your repairs so you’re prepared to speak with a professional about your options.

How “Days in the Shop” Impact California Lemon Law

Under the California Lemon Law, “days in the shop” generally refers to the total number of days your vehicle is out of service for repair of warranty-covered defects. Those days are typically counted from the date you drop the vehicle off (or it is towed in) until the date the dealer says it’s ready for pickup. They’re calendar days, not business days, and they can be cumulative—meaning multiple repair visits for the same issue can be added together, even if they aren’t back-to-back.

This measure matters because California law uses days out of service as one way to show that a manufacturer has had a reasonable opportunity to fix a problem. The commonly cited benchmark is 30 or more total days out of service for warranty repairs within the warranty period. That’s not the only path to a potential lemon claim, though. The law also looks at the number of repair attempts: for example, two or more attempts for a defect that could cause serious injury or death (like brakes, steering, or airbag failures), or four or more attempts for other substantial defects that impair use, value, or safety. Each case depends on its facts.

A few practical points often surprise people. First, days can still count even if the dealer gives you a loaner car or rental—the focus is whether your vehicle is unavailable due to repair. Second, waiting on backordered parts can count toward the total out-of-service time. Third, you don’t need 30 consecutive days; cumulative days across several visits may qualify. On the other hand, problems caused by misuse, accidents, or unauthorized modifications typically aren’t covered, and you generally need to give the manufacturer or authorized dealer a reasonable chance to repair under the warranty.

How to Track Repairs for California Lemon Claims

Good documentation can make or break a potential lemon claim. Start a simple folder (paper or digital) and save every repair order, invoice, and work estimate. Each repair order should list the date in and date out, your exact complaint as you described it, the technician’s findings, the parts replaced, and the mileage in/mileage out. If a symptom is intermittent (for example, the engine stalls occasionally, the backup camera goes black, or the infotainment system reboots), note when it happens and under what conditions—temperature, speed, fuel level, or after software updates.

Keep a running “vehicle diary.” Record every day the car is unavailable for use, including tow dates, days waiting for parts, and the day you were notified it was ready. Save tow receipts, rental or loaner agreements, and any emails or texts with the dealer or manufacturer. Photos and short videos of the defect—like warning lights, leaking fluids, or dashboard error messages—can help show what you’re experiencing. If the vehicle returns with the same issue, reference the prior repair order number so the pattern is clear on the paperwork.

Make sure your warranty coverage is in your file too: the warranty booklet, purchase or lease agreement, and any extended or certified pre-owned warranty documents. If you receive a recall or technical service bulletin (TSB) letter, save it. When you drop off the car, describe the problem in plain terms and ask the service advisor to write your words on the repair order; avoid letting vague terms like “customer states vehicle fine” creep in if it’s not accurate. If you’re considering next steps, many manufacturers have internal claim or arbitration programs—documentation is essential there as well. Because the right path can vary, consider contacting ZapLemon to discuss your situation before making decisions.
