Lemon Car Law and Manufacturer Responsibilities

If your car keeps breaking down and the dealer can’t seem to fix it, you may be wondering whether California’s lemon car law applies. The short answer: it might, depending on your warranty and what’s happened with your repair attempts. Below, ZapLemon explains the basics of the California Lemon Law and what manufacturers are required to do when a vehicle doesn’t live up to its warranty—so you can make informed decisions about next steps.

California Lemon Law: What It Is and How It Works

California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act—protects buyers and lessees of vehicles covered by a manufacturer’s warranty. It can apply to new cars, and, in many cases, to used or certified pre-owned cars that are still under the original factory warranty. Personal, family, or household use vehicles are covered, and certain small-business vehicles may be covered too, depending on weight and fleet size limits.

A vehicle may qualify as a “lemon” when the manufacturer (through its authorized dealer) can’t fix a defect that substantially impairs the use, value, or safety of the vehicle after a reasonable number of repair attempts. California law includes guidelines: for example, two or more repair attempts for a serious safety defect, four or more attempts for the same non-safety issue, or the vehicle being out of service for repairs for more than 30 total days—if these happen within the first 18 months or 18,000 miles from delivery. Even if you’re outside those specific milestones, you may still have rights under the law based on the broader warranty obligations.

If a vehicle qualifies, the manufacturer must generally offer a repurchase (buyback) or replacement, with a mileage offset for the time you used the vehicle before the first repair attempt. Incidental expenses related to the defect—like towing or rental cars—may also be addressed, depending on the facts and the law. Each situation is unique, so it’s wise to gather your records and speak with a professional about your options.

Manufacturer Duties and Your Warranty Rights

Manufacturers must honor their written warranties, which typically promise that covered defects will be repaired free of charge within the warranty period. That means providing parts and labor at authorized dealerships and making timely, competent repair attempts. If the manufacturer can’t fix a covered defect after a reasonable number of tries, California law requires them to move toward a replacement or repurchase—rather than leaving you with a chronically defective vehicle.

Your rights start with your warranty booklet: it explains what’s covered, for how long, and any steps you may need to take (such as contacting the manufacturer directly). Keep every repair order, invoice, and diagnostic report—these documents often show the dates, mileage, and descriptions of recurring issues. If your vehicle is in the shop for multiple days or for repeat visits, ask the dealer to note the specific symptoms you report, and save any towing or rental receipts in case you seek reimbursement later.

Practical tips can help your claim stay on track. Use authorized dealers for warranty repairs, avoid modifications that could void coverage, and ask the service advisor to reference any technical service bulletins (TSBs) relevant to your symptoms. Track days out of service and the number of attempts for the same problem, and consider notifying the manufacturer in writing if problems persist. If you’re unsure whether your situation meets California’s lemon standards, a consultation can clarify your rights and the next steps.
