Key facts that matter before you write

  • Defect impairs use, value, or safety.
  • Vehicle was presented to an authorized dealer for repair.
  • Problem persists after reasonable repair attempts.
  • Repairs happened while the warranty was in effect.

How California law impacts your letter

Song-Beverly basics for demand letters

The law presumes a reasonable number of repair attempts if, within 18 months or 18,000 miles, the vehicle had two or more repairs for a serious safety defect, four or more for other defects, or 30+ total days out of service.

You can request repurchase or replacement, plus taxes, fees, and incidental damages. A usage deduction may apply based on miles before the first repair for the defect.

  • Not required to arbitrate in California before filing suit.
  • Usage deduction estimate: price × (miles at first repair ÷ 120,000).
  • Typical deadline in a letter: give at least 10–15 business days to respond.
  • Statute of limitations is often four years from when you knew of the breach.
  1. Identify the legal basis: California Song-Beverly Consumer Warranty Act.
  2. State the defect and repair history clearly and chronologically.

Step-by-step: write and send your demand letter

Use a clear subject line: California Lemon Law Demand – VIN [your VIN].

Keep the tone factual and professional, and attach copies of key records.

  • Attach repair orders, invoices, and towing/rental receipts.
  • Include photos or videos if they help show the defect.
  1. Gather records: contract, warranty booklet, registration, repair orders.
  2. Create a timeline of each visit with dates, mileage in/out, and results.
  3. Describe the defect and safety impacts in plain language.
  4. State your requested remedy: repurchase or replacement.
  5. Estimate the usage deduction if seeking a buyback.
  6. Set a response deadline (e.g., 15 business days).
  7. Send the letter to the manufacturer’s address in the warranty booklet via certified mail, return receipt requested.
  8. Keep copies of everything and the mailing proof.

Common mistakes to avoid

Small errors can delay or weaken your claim.

Double-check your facts, attachments, and where you send the letter.

  • Sending only to the dealer instead of the manufacturer.
  • Leaving out repair orders or mileage details.
  • Setting an unreasonably short deadline.
  • Using vague descriptions like “car is bad” instead of specific symptoms.
  • Admitting misuse or poor maintenance in writing.
  • Waiting too long and risking deadlines.
  1. Verify the manufacturer’s designated notice address.
  2. Proofread names, VIN, dates, and mileage for accuracy.
