There isn’t one california lemon law time limit that applies to every owner. Since 2025, California runs two separate deadline tracks, and which one applies to you depends on a decision your manufacturer made, often without telling you. One track caps your filing window at six years from delivery. The other runs on a longer clock tied to when you discovered the defect.
If you’ve been putting off a call because you assumed the deadline already passed, don’t assume anything yet. The track that applies to your car changes the math, and in some cases it changes it in your favor.
For the broader rules on repurchases, replacements, and cash settlements, our complete guide to Song-Beverly protections covers the full picture. This post focuses on the one question that gets owners stuck: how much time is actually left.
Why California Now Has Two Deadline Clocks
For decades, one set of rules governed every lemon law claim under the Song-Beverly Consumer Warranty Act. That changed with Assembly Bill 1755, signed in September 2024 and effective January 1, 2025. It introduced new pre-suit procedures for handling claims.
Senate Bill 26, signed in April 2025, turned those procedures into a choice. Manufacturers now elect whether to be governed by the new framework, and the text of both bills lives on the California Legislative Information site if you want to read the source material yourself. Once a manufacturer opts in, that election locks in for five years. The result is a split system: some manufacturers operate on the new track, others still run on the older one, and the difference determines your filing window.
The California Department of Consumer Affairs publishes the current list of opted-in manufacturers each year. Checking that list is the first real step in figuring out your own california lemon law time limit, not guessing based on what you read online. The list changes annually, so the answer for your specific vehicle can shift year to year even if the brand name stays the same.
If Your Manufacturer Opted In
Manufacturers that elected into the new framework follow a structured, faster-moving process:
- A written demand to the manufacturer, sent at least 30 days before you can file suit
- A manufacturer response, offering restitution or replacement within 30 days of that demand
- Completion of that offer within 60 days
- Mandatory mediation early in the case, generally before litigation goes further (exact scheduling varies by court and case, so treat it as a phase, not a fixed number of days)
- A filing window capped at one year after your vehicle’s express warranty expires, or six years from the original delivery date, whichever comes first
That six-year outer boundary sounds generous. It isn’t always. If your warranty expired early and you sat on the problem, the one-year clock inside that boundary can run out well before year six. This is the version of the california lemon law time limit that catches owners off guard most often: the deadline that matters in practice is usually the shorter one-year window, not the six-year cap most people assume they have.
If Your Manufacturer Didn’t Opt In
Not every manufacturer has opted in, and some vehicles fall outside the scope of an election even when the brand has. If yours hasn’t, your claim proceeds under the older Song-Beverly framework. That track generally runs on a longer limitations period, typically counted from when you discovered, or reasonably should have discovered, the defect rather than from the sale date itself.
This is where owners talk themselves out of a claim too early. A car that’s been in the shop for two years on the same transmission problem may still be well within the window, because the clock started running from discovery, not delivery.
What Extends or Shortens Your Window
A few facts move the deadline in either direction:
- Discovery timing. If a defect wasn’t apparent until well after purchase, the clock on the older track may start later than you’d expect.
- Warranty expiration date. On the new track, this date, not your purchase date, sets the one-year countdown.
- Opt-in status changes. A manufacturer’s election is locked for five years, but the list changes annually, so a car bought two years ago and a car bought today from the same brand may sit on different tracks.
- Repair history gaps. A long stretch without a documented repair attempt doesn’t erase your claim, but it does make the timeline harder to prove later.
None of these facts substitute for a records check. They’re reasons to get one, not conclusions to draw on your own.
Common Mistakes Manufacturers Count On
“We’re still working on it.” Manufacturers can stretch informal repair attempts for months, hoping the reader assumes the clock isn’t running yet. It usually is, and every unresolved visit is evidence for your file, not a reason to keep waiting indefinitely.
“You waited too long.” This is often the first line in a denial letter, and it’s an argument, not a ruling. Whether you’re actually outside your window depends on which track applies and when the defect was discoverable, questions a denial letter doesn’t answer for you.
Owners who read our breakdown of the repair and mileage thresholds that trigger a claim already know that manufacturers lean on technicalities. The deadline is no different. It’s a fact to verify, not a reason to give up before checking.
“Your warranty already expired.” Warranty expiration and deadline expiration are not the same event. On the opt-in track, warranty expiration starts the one-year clock. It doesn’t end your rights the moment it happens. Treating those two dates as identical is how owners walk away from claims that are still very much alive.
When to Bring in an Attorney
Figuring out which track applies, what your warranty expiration date actually is, and how much runway you have left is not a quick internet search. It’s a records review.
That review costs you nothing upfront. Under California law, when a lemon law claim succeeds, the manufacturer pays the attorney’s fees, not you. That’s the mechanical reason a $0-unless-we-win model works here: the incentive to move quickly and get it right sits with the firm, not with your wallet.

Frequently Asked Questions
Does the clock start on the day I bought the car? Not always. On the newer opt-in track, the countdown ties to your warranty’s expiration date. On the older track, it generally ties to when the defect was discovered or reasonably should have been. Purchase date alone rarely settles the question.
How do I find out if my manufacturer opted in? The Department of Consumer Affairs maintains a public list of participating manufacturers, updated annually. A quick check against that list, paired with your delivery date, narrows down which set of rules applies to your car.
What if I’m past the 18-month or 18,000-mile mark? That window only affects a legal presumption about repair attempts. It has nothing to do with your filing deadline. Claims filed well past 18 months or 18,000 miles succeed regularly when the repair record supports them.
What happens if I’ve genuinely missed the deadline? It depends on the facts of your case and which track applied. Some owners assume they’re too late based on an outdated rule of thumb, when a records review shows otherwise. That’s worth confirming before you accept a denial as final.
Talk to the Duo Before You Assume It’s Too Late
If you’re not sure whether your window closed, don’t take a guess, and don’t take the manufacturer’s word for it either. A free case review takes about fifteen minutes, and it starts with the two questions that actually matter: which track your manufacturer is on, and what your repair history shows. You can also see how the full process works from first call to resolution before you pick up the phone. Mathew or Eli will look at your records and tell you plainly where you stand. You pay nothing unless we win, and under California law, the manufacturer covers our fees.
