How Much Time Do You Have to Claim a Lemon?

If your new or used car keeps going back to the shop for the same problem, you may be wondering how much time you have to make a lemon law claim in California. The short answer: there are deadlines, but they aren’t always as simple as a single date circled on a calendar. Understanding the difference between warranty periods, legal filing windows, and the “presumption” rules can help you protect your rights and avoid missing your chance to pursue a buyback or other remedy.

California Lemon Law Deadlines: What to Know

In California, most lemon law claims arise under the Song-Beverly Consumer Warranty Act. A common deadline you’ll hear about is a four-year statute of limitations, often measured from when the manufacturer breached its warranty obligations (for example, after failing to fix a covered defect within a reasonable number of attempts). Separate from that filing deadline, the defect typically needs to appear and be reported while the vehicle is under the manufacturer’s warranty. That means even if your warranty later expires, you may still have a claim if the problem started during the warranty period and the maker had a fair chance to repair it.

California also has a helpful “presumption” that applies within the first 18 months or 18,000 miles, whichever comes first. If certain thresholds are met during that window—such as two or more repair attempts for a serious safety issue like brake failure, four or more attempts for a non-safety defect like a stalling issue, or 30+ cumulative days out of service—the law presumes the vehicle is a lemon. This presumption is not a deadline and you can still win a case without it, but meeting it can make a claim easier to prove. Think of it as a legal shortcut, not a timer that shuts off your rights on day 19 or mile 18,001.

Timelines can vary based on the type of warranty and the vehicle’s status. For example, implied warranty rights on new vehicles typically last up to one year from delivery, but related claims may still be governed by longer filing deadlines. Used cars, certified pre-owned vehicles, and service contracts can add another layer of nuance. Federal warranty law (the Magnuson-Moss Warranty Act) may also provide options, sometimes with similar limitation periods. Because the “clock” can start at different times depending on your facts, it’s wise to get a case-specific assessment before assuming you’re out of time.

What Records to Keep and When to Contact ZapLemon

Good documentation can make or break a lemon claim. Keep every repair order, invoice, and work log, even if the dealer writes “no problem found.” Save your purchase or lease agreement, warranty booklet, registration, and title documents. Photos, videos, and notes about symptoms—like dates when the transmission slipped, the infotainment screen froze, or the engine stalled—help show patterns. Emails or texts with the dealer or manufacturer, tow receipts, rental car bills, and roadside assistance records are also valuable.

Consider reaching out to ZapLemon if you’ve had repeated repairs for the same issue, experienced a serious safety defect, or your vehicle has been in the shop for 30 or more cumulative days. It’s also smart to contact us if your warranty is close to expiring, you’re getting the runaround with “could not duplicate” notes, or you’ve opened a case with the manufacturer but aren’t seeing progress. Talking to a professional early can help you understand your timeline and avoid steps that might unintentionally delay or complicate your claim.

While you’re gathering records, continue to report problems promptly and give the dealer a reasonable opportunity to fix them. Describe symptoms clearly, take test drives with the service advisor when possible, and make sure your repair orders accurately reflect your complaints, dates, and mileage. If you move or switch dealers, bring your paper trail with you. These simple steps can preserve your rights and keep your options open if you decide to pursue a claim.

Deadlines under California’s lemon law can be confusing because multiple clocks may be running at the same time. The sooner you understand which rules apply to your car, the easier it is to avoid missing a window that could affect your rights. If you think your vehicle might be a lemon—or you’re not sure how much time you have—ZapLemon can review your situation and explain your options.
