New cars, trucks, SUVs, and motorcycles sold or leased in California with a manufacturer's warranty qualify. CPO and dealer demo vehicles with an active manufacturer's warranty also qualify. Standard used car purchases generally do not.
One of the most common questions consumers ask after experiencing repeated car problems is whether their vehicle qualifies for protection under California’s lemon law. The Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) covers a broad range of motor vehicles, but there are specific requirements a vehicle must meet. Understanding those requirements helps you determine whether you have a viable claim before you ever contact an attorney.
California’s lemon law protects buyers and lessees of new motor vehicles that are covered by a manufacturer’s express warranty at the time of purchase or lease. The word “new” here is important — it refers to the vehicle’s condition at the time of sale, not necessarily its model year. A vehicle that has never been titled to a consumer is new for lemon law purposes, even if it sat on a dealer lot for some time.
The warranty requirement is equally important. Song-Beverly is triggered when defects arise during the term of the manufacturer’s express warranty, which typically includes a bumper-to-bumper limited warranty (commonly three years or 36,000 miles) and a powertrain warranty (often five years or 60,000 miles or longer). If the defect first appears after all applicable warranties have expired, lemon law protection generally does not apply — though other claims may still be available.
The statute uses the broad term “new motor vehicle,” which California courts and the legislature have interpreted to include:
Used vehicles generally do not qualify for protection under the traditional Song-Beverly new vehicle provisions. However, there is an important exception: if a used vehicle was sold with a manufacturer’s new vehicle warranty still in effect — as is common with certified pre-owned (CPO) programs — then the buyer may assert lemon law rights for defects that arise during the remainder of that original warranty period. The key is whether a manufacturer’s express warranty (not just a dealer warranty) still covers the vehicle at the time of the used sale.
California also has a separate used vehicle lemon law (Cal. Civ. Code § 1793.02) that covers some used vehicle purchases made with an implied warranty, though this applies primarily to vehicles sold by dealers to consumers and has more limited remedies.
For full Song-Beverly protection, the vehicle must be purchased or used primarily for personal, family, or household purposes. Vehicles purchased exclusively for commercial or business use are generally not covered by the statute’s strongest provisions, though they may still have warranty rights under other laws.
Vehicles that are used for both personal and business purposes — a very common scenario — are generally still covered as long as personal use is the primary purpose. If you drive your truck to work and use it on weekends, it likely qualifies. If a corporation owns the vehicle and it is driven solely by employees for business deliveries, it may not qualify for individual consumer protections.
There is a limited exception for small businesses: companies that purchase up to five vehicles per year can assert some lemon law rights under Song-Beverly, though their remedies may be somewhat more limited than those available to individual consumers.
Song-Beverly applies to vehicles registered in California and used primarily in the state. The vehicle does not have to have been purchased from a California dealer — if you bought a car out of state but registered it in California and drive it here, you may still be able to assert California lemon law rights. This is particularly important for consumers who purchase vehicles online or while traveling.
A common misconception is that lemon law only applies within the first year or the first 12,000 miles. In fact, coverage is tied to the manufacturer’s warranty period, not a fixed mileage or age limit. If your powertrain warranty covers five years or 60,000 miles and a defect in your transmission first appears at 55,000 miles, you are within the warranty period and may have a claim. The defect and all repair attempts must occur within the warranty period, but there is no additional mileage restriction imposed by the lemon law itself.
Even if your vehicle type qualifies, the defect itself must meet a threshold: it must substantially impair the vehicle’s use, value, or safety. Minor annoyances — a small rattle that does not affect driving, a cosmetic blemish the dealership quickly fixes — typically do not rise to this level. However, recurring defects in core systems (engine, transmission, brakes, steering, electrical systems, software), persistent warning lights, significant fluid leaks, or safety-related issues like unintended acceleration or brake failure almost always qualify.
The vehicle must have been subject to a reasonable number of repair attempts without the defect being resolved. California law creates a presumption of lemon status after four or more attempts to fix the same defect, or after 30 or more cumulative days out of service. Two attempts are sufficient if the defect could cause death or serious bodily injury. Even outside these presumption thresholds, a vehicle may still qualify based on the totality of circumstances.
If your vehicle has been back to the dealer three or more times for the same issue, or has spent two weeks or more in the shop, it is time to speak with a lemon law attorney. The consultation is free, the firm handles your case at no cost to you, and the manufacturer pays attorney fees if you win. You have nothing to lose by making the call — and potentially thousands of dollars to recover.
Under California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8), a vehicle may qualify as a lemon when the manufacturer or an authorized dealer has been given a reasonable number of attempts to repair a defect, and that defect substantially impairs the vehicle’s use, value, or safety. The law does not require any specific number of repair attempts to prove a case — but it does create a legal presumption once certain thresholds are met.
The Song-Beverly Act is widely considered one of the strongest consumer warranty laws in the United States. It applies to new and many used motor vehicles purchased or leased in California for personal, family, or household purposes. The manufacturer is responsible for ensuring its vehicles conform to the express warranty — and if it fails to do so after a reasonable number of attempts, the consumer is entitled to relief.
Importantly, the law places the burden on the manufacturer to rebut the presumption of lemon status once the statutory thresholds are met. This means that once you document enough repair attempts or enough days out of service, the manufacturer must prove your car is not a lemon — not the other way around.
California law establishes two separate statutory pathways under Civil Code § 1793.22 that trigger the lemon law presumption:
Pathway 1 — Number of Repair Attempts:
Pathway 2 — Days Out of Service:
The “warranty period” for purposes of the statutory presumption is generally 18 months from original delivery to the buyer or 18,000 miles, whichever comes first. However, you can still pursue a lemon law claim outside this window — it simply means the presumption does not automatically apply, and you will need to demonstrate a reasonable number of attempts based on the specific facts of your case.
Each repair visit counts as one attempt, even if the dealer says they “couldn’t duplicate the problem” or performed only a diagnostic check. You do not need a successful repair — you need documented visits for the same defect.
Not every car problem qualifies under lemon law — the defect must be covered by the manufacturer’s express written warranty at the time the repair attempts were made. Defects caused by accident, misuse, or unauthorized modifications are generally excluded.
Common defects that qualify include:
The key is consistency: the same defect or symptom must recur across multiple visits. If the dealer repairs one issue and a new, unrelated issue arises, those visits generally cannot be combined toward the repair attempt threshold — though they may each start their own separate count. An attorney can help you analyze your repair records to identify the strongest qualifying defect pattern.
Even if you meet the repair attempt or days-out-of-service threshold, the defect must substantially impair the vehicle’s use, value, or safety. This is a legal standard, and California courts have interpreted each prong broadly in favor of consumers.
Substantial impairment of use means the defect prevents or significantly limits your ability to drive and rely on the vehicle for its intended purpose. A car that stalls on the freeway, fails to start reliably, or requires frequent towing clearly meets this standard. A minor rattle that doesn’t affect driving generally does not.
Substantial impairment of value means a reasonable buyer in the secondary market would pay materially less for the vehicle knowing about the defect — even if the defect does not prevent driving. Persistent electrical gremlins, frame defects that have been repaired, or a vehicle with a documented history of repeated failures can all impair resale value substantially.
Substantial impairment of safety is the broadest prong and arguably the easiest to satisfy. If the defect poses a meaningful risk of injury — brake failure, sudden acceleration, airbag non-deployment, loss of steering — it qualifies, regardless of how many times it has been repaired or how infrequently it occurs. Under § 1793.22, a safety defect requires only two repair attempts to trigger the presumption.
Minor cosmetic issues — a small paint chip, a misaligned trim piece — typically do not qualify on their own. But repeated failures to fix even a cosmetic defect after four or more attempts can still trigger the presumption if the defect affects the vehicle’s value.
The Song-Beverly Act explicitly covers leased vehicles. If you leased a new vehicle and it has a defect covered by the manufacturer’s express warranty that cannot be repaired after a reasonable number of attempts, you have the same rights as a buyer. The manufacturer must either repurchase your lease (reimbursing your down payment, monthly payments, and any remaining lease obligation less the mileage offset) or provide a comparable replacement vehicle.
Used vehicles can also qualify, provided the vehicle is still within the original manufacturer’s express warranty at the time of the repair attempts. A used car sold with three years remaining on a five-year powertrain warranty, for example, is fully protected for those three years. Certified Pre-Owned (CPO) vehicles often come with extended manufacturer-backed warranties that can also qualify.
A few categories of vehicles have different rules or limitations:
If your vehicle qualifies under the Song-Beverly Act, the manufacturer must offer you one of two remedies — and the choice is yours, not the manufacturer’s:
Option 1 — Repurchase (Buyback): The manufacturer repurchases your vehicle. You receive a refund of your down payment, all monthly payments made, your remaining loan balance or lease obligation, taxes, registration fees, and incidental costs (such as rental car expenses and towing). The manufacturer may deduct a mileage offset for the miles you drove before the first repair attempt, calculated by a statutory formula.
Option 2 — Replacement: The manufacturer provides a comparable new vehicle — same make, model, and specifications where possible. You pay nothing for the replacement beyond the mileage offset.
In addition to the primary remedy, you may also be entitled to:
The process typically begins with sending a formal demand letter to the manufacturer. Many cases resolve within a few months through negotiation. If the manufacturer refuses or low-balls the offer, your attorney can file suit in California Superior Court, where juries are generally sympathetic to lemon law plaintiffs.
