This article is provided for general information and does not constitute legal advice. Lemon law procedures changed significantly in 2025 — if you’re dealing with a defective vehicle, consider speaking with a licensed California attorney about how the current rules apply to your specific case.
Realizing your car is a lemon is stressful before you even get to the legal part — you’re stuck making payments on a vehicle you can’t fully use, and possibly one that isn’t safe to drive. The good news is that California has some of the strongest consumer protections in the country for exactly this situation. The rules changed in meaningful ways in 2025, though, so a lot of what’s written about California lemon law online — including older guides — is now out of date. Here’s where things actually stand.
What Makes a Vehicle a “Lemon” Under California Law
California’s lemon law lives inside the Song-Beverly Consumer Warranty Act (Civil Code §§ 1790–1795.8). In plain terms: if a manufacturer can’t repair a defect covered by your warranty after a reasonable number of attempts, it has to replace the vehicle or refund what you paid for it.
“Reasonable number of attempts” isn’t defined by a hard rule, but the Tanner Consumer Protection Act creates a legal presumption that helps consumers avoid arguing about it case by case. Under Civil Code § 1793.22, a defect is presumed to have had a reasonable number of repair attempts if, within the first 18 months or 18,000 miles (whichever comes first):
- The same problem has been through 4 or more repair attempts, or
- A safety-related defect has been through 2 or more repair attempts, or
- The vehicle has been out of service for repairs a cumulative 30 days or more
Meeting this presumption makes your case stronger, but it isn’t the only way to qualify — cases outside these thresholds can still succeed if the defect substantially impairs the vehicle’s use, value, or safety.
What Changed in 2025: AB 1755 and SB 26
This is the part most older lemon law guides haven’t caught up to yet. Assembly Bill 1755, signed in September 2024 and phased in through 2025 (with cleanup amendments from Senate Bill 26), rewrote the procedural side of how lemon law claims move through the system:
- A real statute of limitations now exists. You must file a lawsuit within one year after your vehicle’s express warranty expires, and no later than six years after the vehicle’s original delivery date, whichever comes first. Before 2025, this ran on the more flexible four-year general warranty statute.
- Pre-suit notice is now required (effective July 1, 2025) before you can sue for civil penalties — you have to formally notify the manufacturer in writing first.
- Mandatory mediation applies before full litigation for manufacturers that have opted into the new process.
- The opt-in framework matters: AB 1755’s streamlined procedures only apply to manufacturers that have chosen to participate for a five-year term. If your manufacturer hasn’t opted in, your claim proceeds under the prior rules.
The practical upshot is that the clock on your claim is tighter and less forgiving than it used to be, and it now depends partly on which manufacturer you’re dealing with. Given how manufacturer-specific this has gotten, it’s worth having someone check where your specific case stands before you assume you have more time than you do.
Does It Cover Used Cars, Leases, and Business Vehicles?
Yes to all three, with some conditions:
- Used vehicles are covered as long as there’s still time remaining on the manufacturer’s original written warranty — including many manufacturer Certified Pre-Owned vehicles under their own CPO warranty terms.
- Leased vehicles are covered the same as purchased ones; the remedy is calculated against your lease payments and remaining obligations rather than a purchase price.
- Business-use vehicles are covered too, as long as the business registers five or fewer vehicles and the vehicle’s gross weight is under 10,000 pounds.
It’s a common misconception that lemon law protection disappears the moment a car changes hands. In reality, the warranty travels with the vehicle, not the original owner — a used car with a manufacturer notice history on the same defect can sometimes be one of the stronger cases to bring.
What Compensation Can You Actually Recover?
There are three possible remedies, and which one applies depends on your situation and your preference:
Refund (repurchase). This is the most common outcome. If you purchased the vehicle, the refund includes your down payment, monthly payments, sales tax, prorated registration, and finance charges, plus the manufacturer pays off any remaining loan balance and covers your reasonable attorney’s fees. If you leased, the equivalent applies to your lease payments, down payment, and remaining lease obligations. In both cases, the manufacturer is entitled to deduct a mileage offset — roughly the purchase price multiplied by the mileage at your first repair visit, divided by 120,000 miles — to account for trouble-free use before the defect appeared.
Replacement. The manufacturer provides a comparable new vehicle. It has to be substantially similar to your original — if you want upgraded trim or features, that difference comes out of your own pocket.
Cash-and-keep. If your car’s problems don’t rise to the level of a full “lemon” but still meaningfully reduce its value, manufacturers will sometimes offer a cash settlement while you keep the vehicle, with the rest of the warranty remaining in effect.
You generally get to choose between a refund and a replacement if you win your case — the manufacturer doesn’t get to pick for you.
Is Arbitration Required?
No — and this trips people up. California does not require you to go through arbitration before pursuing a lemon law claim; you can go straight to state court, including a jury trial, if that’s the better path for your case.
That said, many manufacturers offer their own informal, manufacturer-sponsored arbitration program, and it’s often faster: these typically cost the consumer nothing, and cases are usually decided within about 40 days, sometimes sooner. You’re not required to have an attorney represent you at arbitration, but having one generally improves outcomes — and note that attorney’s fees aren’t automatically awarded through arbitration unless the manufacturer has agreed to include them in the arbitrator’s decision. That’s one of several reasons many consumers skip arbitration and go directly to a lawsuit, where fee-shifting is more reliably available.
Building a Strong Claim: What to Document
Whether you end up in arbitration or litigation, the strength of your case usually comes down to your paper trail:
- Take your vehicle in for every issue, even minor ones, and make sure it’s formally logged.
- Report your concerns precisely, and confirm the service advisor recorded exactly what you said — vague repair orders are a common weak point in otherwise strong cases.
- Keep copies of every repair order and invoice.
- Note the names of the service advisors and technicians who worked on the vehicle.
- Once a pattern of repeat repairs is clear, don’t wait — reach out to an attorney given the tighter filing deadlines under AB 1755.
Which Vehicles Get Flagged Most Often?
Almost any make or model can turn out to be a lemon, and manufacturer defect patterns shift from year to year as new models and software systems roll out. Rather than rely on a static list of past problem vehicles, it’s more useful to check a source that’s kept current — Lemon Law Experts maintains an updated manufacturer-by-manufacturer complaint tracker covering everything from transmission and battery issues to advanced driver-assistance system defects.
Should You Hire a Lemon Law Attorney?
You’re not required to have one, particularly for informal arbitration, but the manufacturer is legally required to cover your reasonable attorney’s fees if you win — meaning representation typically costs you nothing out of pocket regardless of the outcome. Look specifically for an attorney whose practice is concentrated in lemon law rather than one who handles it occasionally alongside other consumer matters; the claims process, the new AB 1755 deadlines, and manufacturer-specific opt-in status all take specialized, current knowledge to navigate well.
What Results Look Like
Lemon Law Experts publishes its verdict and settlement history, and the range gives a sense of what different vehicle types have recovered: recent results include a $335,000+ truck settlement, a $280,000+ SUV settlement, a $236,000+ sedan settlement, a $215,000+ convertible settlement, a $201,000+ motorcycle settlement, and a $170,000+ minivan settlement. As with any legal outcome, every case is different and results aren’t guaranteed — the full, ongoing list is available on the firm’s case results page.
Quick Answers
How long am I protected? For the entire duration of the manufacturer’s warranty, and now, under AB 1755, for up to one year after that warranty expires (six years absolute maximum from delivery).
Do I have to pay for arbitration? No — manufacturer-sponsored arbitration in California is free to the consumer.
How long does arbitration take? Typically up to about 40 days, though many cases resolve faster.
Can I pick between a refund and a replacement? Yes, if you win, the choice is generally yours.
The Bottom Line
If your vehicle has been through repeat repairs for the same problem, start documenting everything now, understand that the timeline to act is shorter than it used to be under AB 1755, and get an early read from an attorney who focuses specifically on California lemon law — it won’t cost you anything out of pocket if your case succeeds.
