California Lemon Law: Protecting California Drivers From Defects

When a new or used car keeps breaking down, it can feel like you’re throwing time and money into a problem that never gets fixed. California’s Lemon Law exists to protect consumers in exactly these situations. Below, ZapLemon explains in plain language what the law generally covers, who may qualify, the kinds of defects we see most often, and the practical steps you can take to protect your rights.

What California Lemon Law Covers and Who Qualifies

California’s Lemon Law (part of the Song-Beverly Consumer Warranty Act) generally covers vehicles sold or leased with a manufacturer’s warranty in California. That includes most new cars, trucks, SUVs, vans, and many used or certified pre-owned vehicles that are still under the original manufacturer’s warranty. Leased vehicles can qualify too. The law also extends to electric vehicles, plug-in hybrids, motorcycles, and certain motorhome components. Some small-business vehicles may be covered as well when they meet specific limits, such as a gross vehicle weight rating and fleet size threshold.

To qualify, the problem must be a defect covered by the manufacturer’s warranty that substantially impairs the vehicle’s use, value, or safety—and the manufacturer or its authorized dealer must get a reasonable number of chances to fix it. There isn’t a one-size-fits-all number, but California has helpful “presumptions.” For example, a vehicle may be presumed a lemon if, within the first 18 months or 18,000 miles, the dealer tried to fix the same issue multiple times without success, or the vehicle was out of service for 30 or more cumulative days for warranty repairs. The law can still apply even if your situation falls outside those presumptions; they simply make a claim easier to prove.

Timing and paperwork matter. The defect generally needs to arise during the warranty period, and repairs should be performed by an authorized dealer. Always keep copies of repair orders, work summaries, and communication with the dealership and manufacturer. Because every case is unique and facts matter, it’s wise to talk with a professional. ZapLemon can review your documents and help you understand your options—no promises or guarantees, just clarity about potential next steps.

Common Defects, Repair Attempts, and Next Steps

We regularly hear about recurring problems such as engine stalling, rough shifting or transmission shudder, power loss, brake pulsation, steering pull, recurring “check engine” lights, and electrical gremlins that drain batteries or cause infotainment screens to freeze. For EVs and plug-in hybrids, concerns might include battery range loss outside normal expectations, charging system failures, or software glitches that limit driveability. Safety-related defects—like airbag warning lights, brake system faults, steering issues, or sudden loss of power—can be especially urgent.

A “reasonable number” of repair attempts depends on the defect’s severity and safety implications. As a general guide, California’s presumption may be triggered by two or more attempts for a serious safety defect, four or more attempts for the same non-safety defect, or 30 cumulative days out of service for warranty repairs within the first 18 months or 18,000 miles. But even if you’re outside those numbers or timeframes, you may still have a claim. The key is to give the authorized dealer fair opportunities to fix the problem and to document each visit with a detailed repair order that accurately describes your complaints.

If you’re dealing with repeat defects, here are prudent steps you can take: keep all repair records and notes of what happened, when it happened, and who you spoke with; make sure the dealer writes your exact complaint on the repair order; avoid aftermarket modifications that could complicate coverage; and check your warranty booklet for procedures. Consider contacting a California lemon law professional to discuss your situation and deadlines—California has statutes of limitations that can bar claims if you wait too long. ZapLemon can evaluate your documents, explain potential paths such as repurchase, replacement, or other resolutions, and help you decide whether arbitration or a legal claim makes sense for your situation.
