California Lemon Law for New Car Buyers: A Starter Guide

Buying a new car should bring peace of mind—not repeat trips to the dealership. If your brand‑new vehicle keeps having the same problems, California’s Lemon Law may offer important protections. This starter guide from ZapLemon explains the basics in plain language, outlines common scenarios new car buyers face, and shares practical steps you can take to protect your rights without offering legal advice or guarantees.

California Lemon Law Basics for New Car Buyers

California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act—helps consumers when a new vehicle has significant defects that the manufacturer can’t fix within a reasonable number of attempts. It generally applies to new cars, SUVs, pickup trucks, and vans purchased or leased in California for personal, family, or household use, and in some cases for small business use. The key is that the problem is covered by the manufacturer’s warranty and substantially impairs the vehicle’s use, value, or safety.

How many repair tries count as “reasonable”? California has a legal “presumption” that may apply if issues occur within the first 18 months or 18,000 miles, whichever comes first. While every case is different, guidance often cited includes: two or more repair attempts for a serious safety defect, four or more for other substantial defects, or the vehicle being out of service for repairs for a total of 30 or more days. You don’t have to meet the presumption to pursue a claim—it just makes certain parts of a case easier to prove.

If a vehicle qualifies under the law, typical remedies can include a manufacturer repurchase (commonly called a “buyback”) or a replacement vehicle, plus certain incidental expenses like towing or rental car costs. A mileage offset for your use of the car before the first repair attempt may apply, and processes can differ based on your warranty and facts. Some manufacturers offer arbitration programs, which are optional. Consumers who prevail may be entitled to recover reasonable attorney’s fees under the statute, but outcomes depend on the specifics of each case.

Steps to Take: Repairs, Records, and Warranty

Start by taking the vehicle to an authorized dealership as soon as a problem appears. Clearly describe the symptoms (for example, “transmission hesitates when accelerating,” “check engine light with rough idle,” or “brakes squeal and pull left at highway speed”). Ask the service advisor to write your complaint exactly as you state it on the repair order, and request a copy each time—whether or not they find or fix the issue. If the defect is safety-related, note that on the repair order and follow the dealer’s guidance on safe operation.

Keep a complete paper trail. Save every repair order, invoice, and diagnostic sheet. Track dates in and out of service, mileage at drop-off and pick-up, and any towing or rental expenses. Photos, short videos, or dashboard warning light pictures can help document intermittent problems. If you contact the manufacturer’s customer care line, follow up in writing (email works) and keep copies. Maintain your regular maintenance per the owner’s manual and keep those receipts too.

Know your warranty and your options. Read your warranty booklet to see what’s covered and for how long—bumper‑to‑bumper coverage can differ from powertrain or emissions warranties. If repeated repairs aren’t resolving the issue, consider sending a written notice to the manufacturer and asking about repurchase or replacement procedures. Strict deadlines can apply under California law, so acting promptly is important. For guidance tailored to your situation, consider scheduling a consultation with a California lemon law attorney.
