How long do I have to file a lemon law claim in California?

Generally four years from the date of the breach of warranty under the statute governing written and implied warranties. California courts apply the discovery rule and may toll the period during ongoing repair attempts.

Does the warranty expiring start the clock?

No. The warranty ending does not start the statute of limitations. What matters is when the breach was reasonably discoverable, which usually means when a reasonable consumer would have concluded the manufacturer could not or would not fix the defect.

What is equitable tolling in California lemon law?

When the manufacturer continues to attempt repairs, courts often toll the statute of limitations during the repair period. The rationale: a consumer pursuing warranty repairs is acting diligently and should not lose rights because the manufacturer kept trying.

Can I file after four years?

Usually no, unless tolling or the discovery rule delayed accrual. Close cases require immediate action. Call the same day you suspect you are near the deadline.

Does Magnuson-Moss have a different deadline?

Magnuson-Moss borrows the state statute of limitations, so California claims under both statutes generally share the four-year period.

California Lemon Law Statute of Limitations

Q: When does the clock start?

Typically when the defect was first reasonably discoverable, often the first repair attempt where the defect was documented. Equitable tolling may preserve the claim while repairs continue.

The Four-Year Statutory Period

California Commercial Code section 2725 sets a four-year statute of limitations for breach of any warranty claim, and California courts apply that four-year period to Song-Beverly breach of express warranty and implied warranty of merchantability claims. The text of the Song-Beverly Act itself, at Civil Code sections 1791.1 and 1794, does not specify a different period.

When Does the Clock Start?

Three possibilities, each heavily litigated:

Date of delivery: the default rule under Commercial Code 2725 is that breach of warranty claims accrue upon tender of delivery, unless the warranty extends to future performance.
Date of discovery of the defect: when the warranty extends to future performance, meaning a warranty that promises repair or performance during a defined period, the cause of action accrues when the breach is or should have been discovered. A manufacturer's written warranty covering repairs for 3 years or 36,000 miles is an extension to future performance.
Date of final failure of repair: some California courts treat the breach as occurring when the manufacturer fails a reasonable final repair attempt, particularly when repair attempts are ongoing.

Equitable Tolling During Repair

When a manufacturer continues to accept the vehicle for repair, pulling the vehicle into warranty service and making promises of future fixes, California courts have tolled the statute of limitations. The reasoning: a consumer pursuing warranty repairs is the consumer the statute is designed to protect, and the law does not punish diligence. Aryeh v. Canon Business Solutions, Inc. (2013) 55 Cal.4th 1185 and subsequent cases outline the doctrine.

Practical Application

For a new vehicle delivered in May 2022 with a defect first reported in August 2022 and repair attempts continuing through 2024, a 2026 lawsuit is typically well within the four-year window under any reasonable accrual theory. For a vehicle purchased in 2020 with a final repair attempt in 2022 and no attempts since, 2026 is right at the edge. Paper dates become dispositive.

Near the Deadline? Do Not Wait.

Statutes of limitation are rarely forgiving. If your first repair attempt is approaching four years old, call today. A same-day case assessment costs you nothing and preserves options.

Statute of Limitations for Specific Claim Types

Express warranty breach (Song-Beverly): 4 years, Commercial Code 2725.
Implied warranty of merchantability: 4 years.
Civil penalty claim under 1794(c): travels with the underlying warranty claim.

Common-law fraud: 3 years from discovery.
Negligent misrepresentation: 2 years.

What Preserves the Claim

Filing a BBB Auto Line or manufacturer arbitration demand preserves the substantive claim during the arbitration period.
A written demand to the manufacturer can toll if the manufacturer's response requests additional time.
Continuing repair attempts may support equitable tolling.
Filing the complaint stops the clock as of the filing date.

What Does Not Preserve the Claim

Oral conversations with the dealer.
Ignoring the issue for years after repair attempts stop.
Trading the vehicle in without pursuing the claim first (see Niedermeier v. FCA US LLC (2024) for mileage offset implications on post-sale claims).
Selling the vehicle to a private party without preserving documentation.

Special Cases

Latent defects: defects that could not reasonably be discovered at delivery, such as a hidden chassis defect or an intermittent software fault, may accrue on discovery under the delayed discovery rule.

Rebranded or lemon-resold vehicles: when a dealer sells a prior lemon buyback without disclosure in violation of Civil Code 1793.23, the fraud claim accrues when the consumer discovers the undisclosed history.

Ongoing warranty: a powertrain warranty or EV battery warranty extending 8 to 10 years keeps the future-performance exception active longer than the standard 3/36 warranty, often extending effective accrual.

Frequently Asked Questions

Does selling the car restart anything?
No. Selling can complicate mileage offsets under Niedermeier, but it does not restart the statute.

Can a manufacturer promise to cure in a way that tolls?
Yes, written promises to continue repair or specific offers of cure can support tolling. Save the correspondence.

What if I am outside 4 years but have a strong fraud claim?
CLRA and fraud claims have different limits. A delayed-discovery case may still be viable; call to have the dates reviewed.
