Lemon Law for New Vehicle Owners in California

Buying a brand-new car should feel exciting, not stressful. If your new vehicle is spending more time at the dealership than in your driveway, you may be wondering whether California’s Lemon Law can help. This article explains the basics in plain language so you can recognize potential lemon law issues early, protect your warranty rights, and decide whether it’s time to speak with a professional about your options.

What California’s Lemon Law Means for New Owners

California’s Lemon Law, part of the Song-Beverly Consumer Warranty Act, protects new vehicle owners when a covered defect cannot be fixed after a reasonable number of repair attempts. In everyday terms, if your new car has a substantial problem that the manufacturer or its authorized dealership can’t repair within the warranty period, you may be entitled to a refund or a replacement. The law typically applies to new vehicles bought or leased in California that are primarily used for personal, family, or household purposes.

Coverage is grounded in the manufacturer’s warranty. The problem must arise during the warranty period, and you should give the automaker a fair shot to repair it through an authorized dealer. California also has a guideline often called the “presumption”: during the first 18 months or 18,000 miles (whichever comes first), the law presumes your car is a lemon if certain thresholds are met, such as multiple unsuccessful repair attempts for the same issue or extended time in the shop. This presumption isn’t the only way to qualify—it’s just a helpful shortcut in some cases.

If your vehicle qualifies, the manufacturer may be required to repurchase or replace it, and sometimes reimburse certain incidental expenses like towing or rental cars related to the defect. A repurchase usually includes a “mileage offset,” which is a deduction based on how many miles you drove before the problem first appeared. Every situation is different, so the best next step is to understand your warranty, gather your records, and consider consulting with a professional who can evaluate your specific facts.

Common Defects, Repair Attempts, and Your Rights

Defects that commonly lead to lemon law questions include persistent transmission shuddering or hard shifts, engine stalling or loss of power, repeated check-engine or warning lights, electrical gremlins that drain the battery, malfunctioning infotainment or backup cameras, and safety-related issues like brake failures, steering problems, or airbag warnings. Modern vehicles also rely on advanced driver assistance systems (ADAS), and recurring malfunctions there—such as lane-keep or adaptive cruise control failures—can be significant. What matters most is whether the defect substantially impairs the use, value, or safety of your vehicle.

You’ll typically need to show that the manufacturer had a reasonable number of chances to fix the problem. As a general guideline, California’s presumption looks at things like two or more repair attempts for a serious safety defect, four or more for a non-safety problem, or the vehicle being in the shop for a total of 30+ days for repairs during the first 18 months/18,000 miles. These are not hard-and-fast rules for every case, but they illustrate the kinds of patterns that raise lemon law concerns. Always take your car to an authorized dealership for warranty repairs, and ask for a detailed repair order each time.

Practical steps can strengthen your position. Keep a folder with all repair orders, dates, mileage at drop-off and pick-up, and a simple log of symptoms (what happened, when, and under what conditions). If a warning light appears, take a photo or video when safe to do so. Check your warranty booklet to confirm what’s covered and for how long. If you’ve had repeat problems, consider asking the service advisor whether the manufacturer will review the case for a buyback or replacement. And if you think you’re dealing with a lemon, contact a qualified lemon law attorney to discuss options specific to your situation.
