How to File a California Lemon Law Claim

Filing a California lemon law claim under the Song-Beverly Consumer Warranty Act follows a six-step process: (1) document every repair attempt with repair orders; (2) confirm the manufacturer’s written warranty was in effect; (3) serve the manufacturer with written notice under Civil Code § 1793.2(d)(2); (4) submit a demand for buyback, replacement, or cash settlement; (5) pursue manufacturer-required arbitration where applicable; and (6) file civil litigation if the claim is unresolved. Under § 1794(d), the manufacturer pays the prevailing consumer’s attorney’s fees — which is why nearly every California lemon law claim is filed with attorney representation.

 

 

Step 1: Document Every Repair Attempt

Repair orders are the single most important evidence in a California lemon law case. Every visit to an authorized service facility — including visits where the dealer could not reproduce the defect — should produce a repair order with:

  • Date of drop-off and pickup
  • Mileage at drop-off
  • Consumer’s complaint in the consumer’s own words (“vehicle stalls at highway speed,” not “customer states intermittent issue”)
  • Technician findings and parts replaced
  • Days the vehicle was out of service

Insist on a written repair order at every visit, even diagnostic-only visits. Review the language before leaving — service writers sometimes summarize complaints in ways that minimize the defect. For specifics on what to ask for, see documenting defects.

 

 

Step 2: Confirm Warranty Status

The Song-Beverly Act covers defects that occur while the manufacturer’s written warranty is in effect — including the new vehicle limited warranty, powertrain warranty, hybrid/EV battery warranty, and certified pre-owned warranty. The defect must first manifest during the warranty period; repair efforts that continue after warranty expiration still support the claim.

If your warranty has expired but the defect first appeared during coverage, you may still have a claim. See filing after warranty expiration and statute of limitations.

 

 

Step 3: Serve Statutory Notice

Civil Code § 1793.2(d)(2) requires that the manufacturer — not just the dealer — be given the opportunity to repair the defect after notice. The notice serves two functions: it triggers the manufacturer’s obligation to repurchase or replace, and it satisfies the procedural prerequisite for the lemon law presumption.

A proper notice includes:

  • Identification of the vehicle (year, make, model, VIN)
  • Summary of the defect and repair history
  • Citation to Song-Beverly and request for repurchase or replacement
  • Reasonable time for the manufacturer’s response

A California lemon law attorney drafts and serves the notice. Consumer-served notices through manufacturer consumer-affairs lines are often misrouted or treated as informal complaints rather than statutory demands.

 

 

Step 4: Submit the Demand

After notice, the consumer (typically through counsel) submits a written demand specifying:

The majority of cases settle at the demand stage. Manufacturers with sophisticated lemon law defense operations recognize when the evidence supports liability and prefer to resolve before litigation costs accrue.

 

 

Step 5: Manufacturer Arbitration (When Required)

Some manufacturers — particularly Ford, GM, BMW, and brands using BBB Auto Line — require that consumers participate in informal dispute resolution before filing suit. The arbitration program must be qualified under California’s specific statutory requirements (Civil Code § 1793.22(d)).

Arbitration is non-binding on the consumer — you can reject an unfavorable award and proceed to civil suit. Arbitration is a procedural detour, not a substitute for legal representation.

 

 

Step 6: Civil Litigation

If the demand and arbitration fail to produce an acceptable resolution, the consumer files suit in California Superior Court. Most cases settle in the first 6–9 months of litigation; few reach trial because the § 1794(d) fee-shifting makes prolonged defense expensive for the manufacturer.

See civil litigation for what happens after suit is filed, and case timeline for realistic schedules.

 

 

Why Filing With an Attorney Costs You Nothing

Civil Code § 1794(d) shifts the prevailing consumer’s attorney’s fees onto the manufacturer. McMillan Law Group represents California lemon law clients on a contingency basis — no retainer, no hourly billing, no fee unless we win. Your recovery is not reduced by attorney’s fees; the manufacturer pays them separately.

Frequently Asked Questions

How do I start a California lemon law claim?

Document every repair attempt, confirm warranty status, and get a free case review from a California lemon law attorney. The attorney handles statutory notice, demand, and litigation.

Do I need to go through arbitration first?

Only if the manufacturer’s program is qualified under California’s statutory requirements. Even then, arbitration is non-binding — you can reject an unfavorable award and sue.

How long does it take from filing notice to recovery?

Most cases resolve in 3–9 months from notice. See case timeline.

What if the manufacturer ignores my notice?

Failure to respond is a willful violation under § 1794(c) and exposes the manufacturer to a civil penalty of up to twice damages.

Can I file a claim without an attorney?

You can, but represented consumers settle for substantially more. Because the manufacturer pays your attorney’s fees under § 1794(d), there is no downside to representation.
