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.
A car can be “new” on paper and still feel like a lemon in your driveway. If your recently purchased or leased vehicle spends more time at the dealership than with you, California’s lemon law may offer protections. Below, ZapLemon’s team explains how California defines a lemon under warranty and what to document to protect your rights.
How California Defines a Lemon Under Warranty
California’s lemon law, part of the Song-Beverly Consumer Warranty Act, generally covers new vehicles (and some used or leased vehicles still under the manufacturer’s new-car warranty) that have defects the manufacturer can’t fix within a reasonable number of attempts. The defect must substantially impair the vehicle’s use, value, or safety, and it must arise during the warranty period. Think issues like repeated loss of power, transmission shuddering, brake failures, persistent electrical glitches, or steering defects—not just a squeaky seat.
The law includes a helpful “presumption” during the first 18 months or 18,000 miles, whichever comes first. During that window, a vehicle may be presumed to be a lemon if: the dealer has made at least two repair attempts for a serious safety defect, four or more for the same non-safety defect, or the vehicle has been out of service for warranty repairs for 30 or more cumulative days. These are guidelines, not hard limits—cases outside these numbers can still qualify depending on the facts.
If a vehicle meets the legal standard, the manufacturer may be required to offer a repurchase or replacement, plus certain incidental costs. Which remedy is available and what it includes depends on many factors, such as mileage, the nature of the defect, and your repair history. Every situation is unique, so understanding how the law applies to your specific facts is key—and why a consultation can be helpful before you make big decisions.
What to Document: Repairs, Days Out of Service
Your paperwork can make or break a lemon law claim. Always ask the dealership for a detailed repair order each time you bring the car in, and each time you pick it up. Make sure it lists the date in and date out, odometer readings, your exact complaint in your own words, and the technician’s findings and repairs performed. If a symptom is intermittent, ask the advisor to note that. Keep all invoices, warranty receipts, tow records, and loaner/rental agreements.
Track “days out of service.” California looks at the total number of days your vehicle is unavailable for use due to warranty repairs, including when the dealer is waiting for parts. Keep a simple log at home with dates the car is at the shop. Save emails, texts, and voicemails with the dealer or manufacturer, and take photos or short videos showing warning lights, leaks, or noises. Screenshots of dashboard messages, service app notices, recalls, and technical service bulletins can also be helpful.
Give the manufacturer a fair opportunity to fix the problem by using an authorized dealership for warranty repairs. If you pay for a repair, keep that receipt too—sometimes warranty coverage is disputed and those records matter. Avoid modifications that could complicate diagnosis or give the manufacturer a reason to deny coverage. If you open a case with the manufacturer, keep the case number handy. And if the issues continue, consider a consultation to review your repair history and warranty terms before deciding next steps.
