Deadlines matter in lemon law. If your car keeps breaking down and the dealer can’t fix it, California’s lemon law may offer a way out—but only if you act within certain time limits. Below, we explain how long you generally have to file a lemon law claim in California, how the “clock” starts, and what steps you can take now to protect your rights, all in plain language.
California Lemon Law Deadlines: What to Know
In California, most lemon law claims under the Song-Beverly Consumer Warranty Act are subject to a four-year statute of limitations. That four-year period typically runs from when your claim “accrues,” which means when you have a legally recognized reason to sue—not necessarily the date you bought the car. Other related claims (like fraud or deceptive practices) may have different deadlines, often shorter, which is why getting individualized guidance is important.
Don’t confuse the filing deadline with the “lemon law presumption.” California presumes a vehicle is a lemon if, within the first 18 months or 18,000 miles, it meets certain repair thresholds (for example, multiple unsuccessful repair attempts for the same problem or 30 total days out of service). That presumption helps prove your case but it is not the deadline to file. You can still pursue a claim after that window if your warranty problem began during coverage and the manufacturer failed to fix it within a reasonable number of attempts.
Used and certified pre-owned vehicles can also qualify if they were sold with a manufacturer or dealer warranty and the defect arose during that warranty period. Even if your written warranty has expired today, you may still bring a claim if the defect and repair attempts happened while coverage was active. Keep every repair order, warranty booklet, recall notice, and email with the dealer or manufacturer—those documents are often critical in showing when the problem started and how many times you asked for a fix.
How the Statute of Limitations Clock Starts
When does the four-year “clock” start? In many California lemon law cases, a claim accrues when the manufacturer (or its authorized dealer) fails to repair the defect after a reasonable number of attempts during the warranty period, and you knew or should have known the problem wasn’t going to be fixed. That moment can be different from the purchase date and can differ from case to case. Because “accrual” is fact-specific, getting a case review can help you avoid cutting it too close.
Consider a common scenario: you buy a new SUV, and within the first year the transmission slips. You take it in three times; each time the dealer says “cannot duplicate.” On the fourth visit, the issue persists, and the vehicle has now been out of service for over 30 days combined. Your claim may accrue around this point—when it’s clear reasonable repair efforts failed. Contrast that with an implied warranty claim (the basic promise that the vehicle is fit to drive), where legal timelines can be tied more closely to the delivery date. Different legal theories can have different clocks.
Some events can pause or extend the filing deadline, a concept known as “tolling.” Examples may include certain consumer-protection class actions, military service protections, or exceptional circumstances recognized by courts. However, back-and-forth with the dealer or waiting for parts usually does not automatically stop the clock. Practical tips: schedule repairs promptly, document every visit, ask for detailed repair descriptions on invoices, and consider a consultation sooner rather than later so you understand your specific timeline.
