Lemon Law Deadline vs Warranty Expiration: What's the Difference?

Is my lemon law deadline the same as the date my warranty expires?

Side-by-Side Comparison

What Warranty Expiration Means

Your warranty has an end date, usually stated in years and miles, whichever comes first. After that point, the manufacturer generally stops covering new defects under that warranty.

Many cars have more than one warranty, each with its own end point. The basic warranty, the powertrain warranty and any emissions or battery coverage may all expire at different times. Check your booklet for each one.

Warranty expiration is about repair coverage. It tells you whether the manufacturer has to pay to fix a newly discovered problem. It does not, by itself, end your legal rights for problems that started earlier.

If a defect first showed up during the warranty, the manufacturer's duties for that defect do not simply vanish on the expiration date. That is why the expiration date and the lemon law deadline should be kept separate in your mind.

Some warranty coverage starts before you take delivery. If you bought a demo or dealer-owned car, the warranty may have started when the car was first put into service. Ask the dealer for the warranty start date for your VIN so you know your real end date.

Leased vehicles follow the same idea. The warranty runs with the car, and California's lemon law covers leases too.

What the Lemon Law Deadline Means

The lemon law deadline is the time limit to bring a legal claim. In California, warranty claims generally have a four-year statute of limitations under Commercial Code 2725.

The timing rules are technical. When the clock starts can depend on the type of claim and the facts of your case. That is why this page does not try to calculate your deadline for you.

A claim filed too late can be barred, even if it was otherwise strong. Missing the deadline is one of the few mistakes that cannot be fixed later.

The safest approach is to talk to a lemon law attorney as soon as a problem keeps coming back. An early review costs nothing and lets the attorney check your dates while there is still time.

Do not rely on internet calculators or general rules of thumb for your deadline. Your attorney will look at your purchase date, your first repair date and other facts to see which timing rules apply.

If you are close to four years from your purchase or from your first repair for the defect, treat that as urgent. Call an attorney that week rather than waiting for the next problem.

• Generally four years for warranty claims
• Start date depends on the facts
• A late claim can be barred
• Get dates checked early

Why a Claim Can Outlast the Warranty

Many drivers are surprised to learn that a lemon law claim can continue after the warranty ends. The key is when the defect first showed up.

A claim is not limited to 18 months or 18,000 miles; it can still succeed if the defect first appeared during the warranty. The Tanner Act presumption in Civil Code 1793.22(b) is limited to that window, but the general rule in Civil Code 1793.2(d)(2) is not.

For example, a defect that first appeared and was repaired during the warranty may keep returning after the warranty ends. The later repair visits can still be part of the history, because the defect began while it was covered.

This is one reason to report every symptom while the car is under warranty, even small ones. A repair order from the warranty period can be the proof that the defect started in time.

Keep in mind that a car does not need to be out of warranty to qualify. Many claims are brought while the car is still covered. If the problem keeps returning now, there is no benefit to waiting for the warranty to run out.

The remedy is the same either way. Under Civil Code 1793.2(d)(2), if the defect was not fixed after a reasonable number of attempts, the manufacturer must replace or repurchase the vehicle.

AB 1755 and SB 26 Timing Steps

California added new process steps for lemon law cases in 2025. California changed the process in 2025. Where the manufacturer opted in, AB 1755 (Code of Civil Procedure 871.20 and following) and SB 26 now call for written notice before suit, an early swap of documents and a mediation for many claims.

These steps have their own deadlines. They are separate from the statute of limitations and separate from your warranty dates. Missing one can affect how your case moves forward.

Not every manufacturer opted in, and the rules apply to many claims, not all. Your attorney will check whether your manufacturer is covered and which steps apply.

Because of these steps, the time between deciding to bring a claim and actually filing a lawsuit may be longer than you expect. That is another reason not to wait until the last minute.

If you receive a letter from the manufacturer about the claim, keep the envelope and note the date you received it. Dates matter under these steps, and your attorney may need to know exactly when each document arrived.

Your attorney will tell you which steps apply and what you need to do, if anything. In many cases, the attorney handles the notices and document exchange for you.

Example: A Warranty That Ends Mid-Problem

This is a made-up example. Olivia buys a new SUV. In its second year, the infotainment and backup camera start shutting off while she drives. The dealer works on it three times before her basic warranty ends.

A month after the warranty ends, the screen goes dark again. The dealer says the repair is no longer covered. Olivia assumes her rights ended with the warranty, but a friend suggests a free case review.

Her attorney looks at the dates. The defect first showed up and was repaired during the warranty, so the attorney treats the later failure as part of the same defect's history. The attorney also checks the four-year limitations period under Commercial Code 2725 and whether her manufacturer opted in under AB 1755.

In this example, the warranty expiration and the legal deadline turned out to be very different dates. The example shows how an attorney reviews timing, not what any case will result in.

Olivia also keeps making her loan payments and keeps the SUV, rather than trading it in, so it remains available for inspection. Those choices protect her options while the attorney reviews the claim.

She also gathers every repair order from the warranty period, including the very first visit, because that first visit shows when the defect began. Her attorney uses it as the starting point for the timeline.

Common Timing Mistakes

Timing mistakes are some of the most costly in lemon law cases, and they are often avoidable. Most come from mixing up the warranty date with the legal deadline.

Another mistake is ignoring letters from the manufacturer. If you receive a formal settlement offer under Code of Civil Procedure 998, there are consequences for rejecting it and not doing better at trial, including possibly losing post-offer costs. Always review a 998 offer with your attorney before the deadline in the offer.

Trading in or selling the car before getting advice is another common mistake. It does not automatically end a claim, but it can make the claim harder to prove and change how it works.

Finally, do not assume a manufacturer's statement that you are too late is correct. Manufacturers have their own interests. Have your dates checked by your own attorney.

A related mistake is assuming that a manufacturer's goodwill repair or extended coverage offer resets the clock. It may not. Ask your attorney before you rely on any offer.

• Assuming the claim ended when the warranty ended
• Letting years pass between the first repair and a call to an attorney
• Not reporting small symptoms during the warranty
• Trading in the car before getting advice
• Ignoring AB 1755 notice or mediation dates
• Letting a manufacturer offer expire without review

Step-by-Step: Protect Your Timeline

You can protect yourself with a few simple steps. None of them commit you to a lawsuit. They simply keep your options open.

A free case review costs nothing. Under Civil Code 1794(d), the manufacturer pays your attorney fees, costs and expenses when you win, so you pay $0 out of pocket. Call 877-536-6620.

If you are unsure where to find your repair orders, ask the dealer's service department for a printout of your vehicle's service history. Dealers keep records of warranty work and can usually print them for you.

Write the dates on a single page and bring it to the review. A simple timeline helps the attorney spot the earliest repair visit and check each deadline quickly.

Avoid signing any release or settlement while you wait. Releases can end your claim, so have them reviewed first.

• Find your warranty booklet and write down each coverage end date
• Find the repair order for the first visit for the defect
• List every later visit with date and mileage
• Keep making your loan or lease payments
• Get a free case review before the warranty or deadline passes

When Lemon law deadline Is the Better Choice

• The defect first showed up while the warranty was active
• Your warranty recently expired but the problem was reported before then
• You are close to four years from your purchase or first repair

When Warranty expiration Is the Better Choice

• Your warranty is still active and the dealer can keep trying to repair it
• The problem is new and has had only one repair visit
• You want to use remaining coverage for a covered repair

Key Facts (as of October 2026)

• Warranty claims generally have a four-year statute of limitations (Commercial Code 2725), and timing rules are technical, so talk to an attorney early.
• Claims can still succeed outside 18 months or 18,000 miles if the defect first showed up under warranty.
• For manufacturers that opted in, AB 1755 and SB 26 added pre-lawsuit written notice, early document exchange and mediation steps and deadlines.

What Our Clients Say on Google

“Even after multiple PCM software updates and the service center telling me it was just 'adaptive learning,' the car was still lunging and hesitating at highway speeds. I paid no out-of-pocket legal fees because the law requires the manufacturer to pay them.”
