How to File a California Lemon Law Claim
Nobody wants to deal with a vehicle that is a “lemon.” It can be frustrating and time consuming. The good news is that California’s Lemon Law is favorable to consumers and helps hold vehicle manufacturers liable. Formally known as the Song-Beverly Consumer Warranty Act, it gives buyers and lessees of defective vehicles the right to a refund or replacement when a manufacturer cannot fix a substantial problem after a reasonable number of attempts.
Having an experienced lemon law attorney on your side is one of the most important things in recovering the money you are owed. There are several hoops that must be jumped through in order to obtain a successful result. Even with California law on your side, most manufacturers will not easily refund the purchase price of your defective car. Below, we walk through how the process works, step by step.
Step 1: Confirm Your Vehicle Has a Substantial Defect
Not every problem qualifies. The Lemon Law applies to a substantial defect — one that impairs the vehicle’s use, value, or safety and is covered by the manufacturer’s warranty. A transmission that won’t shift, brakes that fail, or an engine that repeatedly stalls will generally qualify. Minor cosmetic issues, such as a small rattle or a blemish in the paint, usually will not. The defect must also arise during the warranty period, not from your own misuse or an accident.
Step 2: Give the Manufacturer a Reasonable Number of Repair Attempts
You must take your vehicle in to be repaired a “reasonable number” of times before it is considered a lemon. It is very important that you use a repair facility authorized by the manufacturer to perform the work under warranty. You don’t want the manufacturer to be able to argue that a local, non-certified mechanic caused or worsened the problem.
So what counts as a “reasonable number”? The standard is somewhat subjective, but California law provides a helpful shortcut called the lemon law presumption, codified in the Tanner Consumer Protection Act at California Civil Code § 1793.22. A reasonable number of attempts is presumed if, within the first 18 months after delivery or 18,000 miles (whichever comes first), any of the following occurs:
- Two or more repair attempts for a defect that is likely to cause death or serious bodily injury (a safety defect); or
- Four or more repair attempts for the same non-safety defect; or
- The vehicle has been out of service for repair for more than 30 cumulative days (the days do not need to be consecutive).
When the presumption applies, the burden shifts to the manufacturer to prove your vehicle is not a lemon — a significant advantage for you. Importantly, these thresholds are guideposts, not hard limits. You may still qualify outside the 18-month/18,000-mile window by showing the manufacturer had a reasonable opportunity to repair a persistent defect and failed. If the manufacturer refuses to attempt a repair at all, courts generally treat the repair requirement as satisfied.
Step 3: Collect and Organize Your Documentation
If you believe your car is a lemon, start collecting your paperwork — this is often what makes or breaks a claim. Gather documentation from every repair attempt, including each repair order or invoice detailing the issues you reported, the work performed, and the outcome. These records also capture the dates, mileage, and other details that establish whether you meet the presumption above.
Other important items to collect include your purchase or lease contract, the warranty booklet, your own written notes, photos or videos of the defect, and your vehicle’s service history. The more complete your records, the stronger your position when your attorney negotiates with the manufacturer.
Step 4: Understand What You May Be Entitled To
Under Civil Code § 1793.2, if your vehicle qualifies, the manufacturer must either replace it with a substantially identical vehicle or repurchase it. Most consumers choose the refund. A buyback generally includes the purchase price you paid — vehicle price, sales tax, registration, and finance charges — plus incidental costs such as towing and rental cars, minus a mileage offset for the use you got before the first repair attempt.
The offset is set by statute: (miles at the first repair attempt ÷ 120,000) × purchase price. For example, a $40,000 car with 6,000 miles at the first repair visit would carry an offset of about $2,000. Note that the offset is based on the mileage at the first repair attempt — not your current mileage — a detail some manufacturers get wrong to your disadvantage.
Where a manufacturer willfully refuses to honor its obligations, Civil Code § 1794 allows a civil penalty of up to two times your actual damages, on top of the buyback. California law also requires the manufacturer to pay your attorney’s fees and costs when you prevail, which is why most lemon law attorneys — including our firm — handle these cases with no upfront cost to you.
Step 5: Know the Recent Rule Changes Before You File
Two developments in 2025 changed how claims proceed. First, a 2024 California Supreme Court decision narrowed protections for many used-vehicle buyers. Second, procedural reforms added new pre-litigation notice requirements, deadlines, and in some cases mandatory mediation — and which rules apply can depend on whether your vehicle’s manufacturer has opted in, a list the California Department of Consumer Affairs publishes. We break these down in detail in our guide to the recent changes to California’s Lemon Law for used vehicles. Because these deadlines are strict, acting promptly is more important than ever.

Frequently Asked Questions
How many repair attempts does it take to qualify as a lemon in California?
There is no single magic number, but the lemon law presumption generally applies after four attempts for the same non-safety defect, two attempts for a serious safety defect, or more than 30 cumulative days out of service — all within the first 18 months or 18,000 miles. You can also qualify outside these thresholds by proving the manufacturer had a reasonable opportunity to repair and failed.
Does the California Lemon Law cover used cars?
It can, but the rules tightened in 2025. A used vehicle generally needs to still carry a manufacturer’s warranty, and a recent California Supreme Court ruling narrowed the refund-or-replace remedy for many used-car buyers. Certified Pre-Owned vehicles sold with a new warranty are more likely to qualify. See our guide to the 2025 used-vehicle changes for the full picture, and consider speaking with an attorney about your specific vehicle.
How much money can I recover?
A typical buyback returns what you paid for the vehicle (price, taxes, fees, and finance charges) plus incidental costs, minus a mileage offset for pre-defect use. If the manufacturer’s conduct was willful, Civil Code § 1794 permits a civil penalty of up to two times your actual damages. The exact figure depends on your facts, so a case-specific review is the only way to know.
Do I have to pay for a lemon law attorney out of pocket?
Generally, no. Under the Song-Beverly Act, a prevailing consumer’s reasonable attorney’s fees and costs are paid by the manufacturer. As a result, most lemon law cases — including ours — are handled on a contingency basis with no upfront cost to you.
Does the vehicle have to be repaired by the dealer?
For warranty repairs that count toward a lemon law claim, yes — use a manufacturer-authorized repair facility. Repairs by an independent, non-certified mechanic may not count and can give the manufacturer an argument that outside work caused the problem.
What if my car has been in the shop many days but only for one or two visits?
Days out of service is an independent pathway to the presumption. If your vehicle has been unavailable for warranty repairs for more than 30 cumulative days within the first 18 months or 18,000 miles, it may qualify even without four separate repair visits.
Is there a deadline to file?
Yes, and the 2025 procedural reforms added new pre-litigation notice steps and timelines. Because missing a deadline can jeopardize an otherwise strong claim, it’s best to consult an attorney as soon as you suspect your vehicle is a lemon rather than waiting.
