How Long Do I Have to File a California Lemon Law Claim?

The short answer: California’s lemon-law statute of limitations is four years from the date of delivery under California Commercial Code § 2725. But several practical timing considerations matter beyond the statute itself.

The default rule: four years from delivery

For Song-Beverly Act claims, California courts apply the four-year limitations period for written-warranty breach under California Commercial Code § 2725. The clock generally starts on the date of delivery (the date you took possession of the vehicle), not the date the defect first appeared.

This is broader than buyers often realize. A car delivered in 2022 with a transmission defect that didn’t manifest until 2025 can still be the subject of a lawsuit filed in 2026 — well within the four years from delivery.

The future-performance exception

Section 2725(2) of the Commercial Code carves out an exception when a warranty explicitly extends to future performance of the goods and discovery of the breach must await the time of such performance. In this case, the four-year clock runs from the date the breach is or should have been discovered.

California courts have applied this exception unevenly. The leading case is Mexia v. Rinker Boat Co. (2009), which held that the implied warranty of merchantability can extend to future performance under Song-Beverly. Other appellate panels have read Mexia narrowly. The practical effect: if your defect manifested late in the four-year window, an experienced attorney may still have viable arguments.

See our detailed statute of limitations article for the full analysis.

When does the clock actually start?

For most cases, the clock starts on delivery date — the day you took possession of the vehicle. Specifically:

New-vehicle purchase: delivery date is the day you drove off the lot.
Used-vehicle purchase with original warranty active: delivery date for warranty purposes is generally the original new-vehicle delivery date; for your lemon-law claim, the relevant date is when you bought it.
Lease: delivery date is when you took possession.
CPO: same as used-vehicle.

What can restart or extend the clock?

Several events can effectively restart or toll the limitations period:

Each new repair attempt

Each repair attempt can be argued as a new breach if the manufacturer’s failure to fix is the actual violation under § 1793.2(d)(2). This argument is fact-specific and not always successful, but it’s available.

Written acknowledgment of defect

A manufacturer letter accepting responsibility for a particular defect — common in TSB or extended-warranty situations — can extend the limitations period.

Equitable tolling

If the manufacturer concealed the defect or its cause (rare, but it happens), the clock may pause until discovery.

Pending arbitration

Manufacturer-sponsored arbitration programs (BBB Auto Line, etc.) may toll the statute while arbitration is active.

Magnuson-Moss limitations

The federal Magnuson-Moss Act has no independent statute of limitations. Courts apply the most analogous state-law period — which in California means four years under Commercial Code § 2725, the same period as Song-Beverly. Pleading Magnuson-Moss alongside Song-Beverly does not extend the deadline.

Implied warranty timing

The implied warranty of merchantability under Song-Beverly attaches at delivery and runs for at least 60 days but not more than one year (§ 1791.1(c)). The breach of the implied warranty is still subject to the four-year statute of limitations from delivery. See our implied vs. express warranties article for the framework.

The practical timeline

Beyond the statute of limitations, several practical timing factors matter:

Mileage offset increases with time

The mileage offset under § 1793.2(d)(2)(C) is calculated based on miles driven before the first repair attempt. The offset doesn’t grow just because you wait to file — but if the defect didn’t manifest until you’d already driven 30,000 miles, that’s the offset you’ll see.

The longer you wait after the first repair attempt to actually file a claim, the more your case fades in the records but the offset doesn’t grow.

Warranty period vs. statute of limitations

The defect must have manifested during the warranty period (e.g., the 5-year/60,000-mile powertrain warranty). But you don’t have to file the lawsuit during the warranty period — the four-year statute of limitations from delivery generally controls the lawsuit deadline.

So: a defect that emerged at year 4 of a 5-year warranty can be the subject of a lawsuit filed in year 4 — well after the warranty has expired by year 6 or 7. The defect’s manifestation during warranty matters; the lawsuit’s filing date is controlled by the limitations period.

Documentation degradation

Repair orders get lost. Service advisors leave dealerships. Records get harder to gather as time passes. While the legal deadline may be 4+ years, the practical case quality degrades the longer you wait.

Manufacturer’s settlement posture

Manufacturers’ settlement values can shift based on the timeline. Cases filed promptly after the manufacturer recognizes its exposure tend to settle at fuller value than cases filed years later.

What if you’re past four years?

If your vehicle was delivered more than four years ago:

Future-performance exception arguments may apply.
Repair-attempt-as-new-breach theory may apply.
Equitable tolling may apply if the manufacturer concealed.
Magnuson-Moss claims are likely also time-barred (same four-year period).

The analysis is harder past four years but not always hopeless. Get a free case review to know.

What if you’re past five or six years?

Beyond six years, viable Song-Beverly claims are uncommon. The combination of:

Statute of limitations past four years.
Future-performance exception arguments weakening.
Documentation degradation.
Case quality issues.

…makes representation harder. Most California lemon-law attorneys won’t take cases beyond five or six years from delivery without specific extenuating circumstances.

The takeaway

File promptly. If you suspect you have a lemon-law claim, get a free case review early in the timeline. The closer to the defect manifestation and the active warranty period, the cleaner the case. The longer you wait, the harder it becomes to win — even if you’re technically within the four-year window.

If you’re worried about a deadline, the answer to “do I have time?” is almost always “yes, but don’t wait.” A California lemon-law attorney will tell you whether your case is viable and what the realistic timeline looks like.
