Song-Beverly Consumer Warranty Act: California's Lemon Law Explained

The Foundation of California Consumer Protection

The Song-Beverly Consumer Warranty Act is the official name of California’s Lemon Law. Codified in California Civil Code Sections 1790 through 1795.8, it is widely regarded as one of the strongest consumer protection statutes in the United States. While most people associate it exclusively with defective cars, the Song-Beverly Act actually provides far broader protection, covering virtually any consumer product sold with a warranty in California.

Named after its legislative sponsors — California State Senator Alfred Song and Assemblyman Lou Beverly — the Act was first enacted in 1970 and has been amended multiple times since. Its purpose, as stated in the statute, is to ensure that manufacturers and sellers of consumer goods maintain adequate service and repair facilities and honor the warranties they provide.

This guide provides a comprehensive explanation of the Song-Beverly Act: its history, what it covers, how it works, and why it gives California consumers more power than consumers in almost any other state.

A Brief History of the Song-Beverly Act

Before 1970, California consumers who purchased defective products had limited recourse. Warranty disputes were governed primarily by the Uniform Commercial Code (UCC), which required consumers to prove complex breach-of-contract claims and offered limited remedies. Manufacturers could — and frequently did — stonewall consumers by providing inadequate repairs, imposing unreasonable conditions, or simply ignoring warranty obligations.

The Song-Beverly Act changed the landscape dramatically. Key milestones include:

1970: The original Act was signed into law, establishing basic warranty obligations for manufacturers and sellers of consumer goods in California.
1982: Major amendments strengthened the Act, particularly for motor vehicles. The Tanner Consumer Protection Act (California Civil Code Section 1793.22) was added, creating the lemon law presumption — a rebuttable presumption that a vehicle is defective if repair attempts exceed specific thresholds.
1990s–2000s: Additional amendments clarified the Act’s application to leased vehicles, refined the remedies available to consumers, and addressed the growing complexity of modern consumer products.
2000s–Present: Courts have continued to interpret and expand the Act’s protections through case law, addressing issues like electronic vehicles, software-driven defects, and the scope of implied warranties.

Today, the Song-Beverly Act stands as a model for consumer protection legislation nationwide.

What Does the Song-Beverly Act Cover?

Consumer Goods — Not Just Vehicles

While the Song-Beverly Act is best known for its application to vehicles (the “lemon law”), it covers any new consumer good sold at retail in California that comes with an express warranty. Under California Civil Code Section 1791(a), “consumer goods” include:

Motor vehicles — cars, trucks, SUVs, vans, motorcycles, and RVs
Electronics — computers, televisions, smartphones, and tablets
Appliances — refrigerators, washing machines, dishwashers, and HVAC systems
Furniture — items sold with a manufacturer’s warranty
Medical devices — wheelchairs, hearing aids, and other warranted medical equipment
Any other tangible good sold at retail with a manufacturer’s warranty

This broad coverage means that if you purchased a warranted product in California and the manufacturer cannot fix it, the Song-Beverly Act may entitle you to a refund, replacement, or damages — regardless of whether the product is a vehicle.

That said, the Act’s most powerful provisions — particularly the lemon law presumption under Section 1793.22 — apply specifically to motor vehicles. For non-vehicle consumer goods, the general warranty obligations still apply, but the specific repair-attempt thresholds and presumptions differ.

Vehicles Covered Under the Lemon Law Provisions

For purposes of the motor vehicle lemon law provisions, the Song-Beverly Act covers:

New vehicles purchased or leased in California with a manufacturer’s warranty
Leased vehicles — the Act explicitly protects lessees (see our guide on lemon law for leased vehicles)
Certified pre-owned (CPO) vehicles — if sold with a new manufacturer’s warranty
Used vehicles — if still covered by the original manufacturer’s warranty at the time the defect first appeared (for more, see lemon law vs. used car warranty)
Dealer-owned vehicles (demos) — if sold with a warranty
Electric vehicles — fully covered, including battery and software defects

The Act applies to vehicles from all manufacturers, whether domestic or foreign. Whether you drive a Toyota, Honda, Ford, Chevrolet, Tesla, BMW, Hyundai, Kia, or any other brand, the Song-Beverly Act has you covered.

Express Warranties vs. Implied Warranties

One of the Song-Beverly Act’s most important features is its treatment of both express and implied warranties.

Express Warranties

An express warranty is a written promise by the manufacturer that the product will meet certain standards or will be free from defects for a specified period. For vehicles, the most common express warranties are:

Bumper-to-bumper warranty — typically 3 years/36,000 miles (varies by manufacturer)
Powertrain warranty — typically 5 years/60,000 miles (some manufacturers offer 10 years/100,000 miles)
Battery warranty (EVs) — typically 8 years/100,000 miles
Corrosion/rust warranty — varies by manufacturer

Under the Song-Beverly Act (California Civil Code Section 1793.2), if a manufacturer provides an express warranty, it must:

Maintain sufficient service and repair facilities in California to carry out the warranty terms
Repair defects that impair the use, value, or safety of the product within a reasonable time
Replace or refund the product if it cannot be repaired after a reasonable number of attempts

Implied Warranties

Implied warranties are not written promises — they are legal obligations that arise automatically by operation of law whenever consumer goods are sold in California. The Song-Beverly Act recognizes two types:

Implied Warranty of Merchantability (California Civil Code Section 1791.1) This warranty guarantees that the product is fit for its ordinary purpose. A car must be able to transport you safely and reliably. A refrigerator must keep food cold. A laptop must function as a computer. If a product fails at its basic intended purpose, the implied warranty of merchantability has been breached.

Implied Warranty of Fitness for a Particular Purpose (California Civil Code Section 1791.1) If a seller knows that the buyer is purchasing a product for a specific purpose and the buyer relies on the seller’s expertise, there is an implied warranty that the product will be suitable for that purpose. For example, if you told a dealer you needed a truck capable of towing 10,000 pounds and they sold you a model rated for only 5,000 pounds, the implied warranty of fitness may be breached.

Why Implied Warranties Matter

Implied warranties are critical because they cannot be waived or disclaimed under the Song-Beverly Act. California Civil Code Section 1793 prohibits manufacturers and sellers from disclaiming implied warranties on consumer goods sold with an express warranty. This means that even if the manufacturer’s written warranty has expired, the implied warranty may still provide protection.

The duration of the implied warranty runs concurrently with the express warranty but lasts for a minimum of 60 days after delivery for new goods, and up to one year for used goods sold with a written warranty. Courts have interpreted these provisions to extend implied warranty protection for a reasonable period, even beyond the express warranty term in some cases.

The Lemon Law Presumption (Section 1793.22)

The Tanner Consumer Protection Act, incorporated into the Song-Beverly Act as California Civil Code Section 1793.22, creates a rebuttable presumption that a vehicle is a lemon if certain conditions are met. This presumption is the most powerful tool available to California consumers with defective vehicles.

When the Presumption Applies

The presumption arises if, within the earlier of 18 months from delivery or 18,000 miles, any of the following occurs:

Two or more repair attempts for a defect that could cause death or serious bodily injury
Four or more repair attempts for any other defect that substantially impairs the vehicle’s use, value, or safety
30 or more cumulative calendar days out of service for warranty repairs

What the Presumption Does

When the presumption applies, the burden of proof shifts to the manufacturer. Instead of you having to prove your vehicle is a lemon, the manufacturer must prove it is not. This is an enormously advantageous position for consumers because it forces the manufacturer to come forward with evidence that the repairs were adequate or that the defect does not substantially impair the vehicle.

Beyond the Presumption

It is important to understand that the presumption is not a prerequisite for a lemon law claim. You can still bring a claim under the Song-Beverly Act even if your repair attempts fall outside the 18-month/18,000-mile window. The claim just proceeds without the benefit of the presumption, meaning you bear the burden of proving the vehicle qualifies. For a deeper discussion of the overall claims process, see our California Lemon Law guide.

Remedies Under the Song-Beverly Act

The Act provides several remedies for consumers whose vehicles or other products qualify:

Refund (Buyback)

Under California Civil Code Section 1793.2(d)(2), the manufacturer must refund:

The full purchase or lease price (or all lease payments for leased vehicles)
Collateral charges — taxes, registration, finance charges, and incidental costs
A mileage offset is deducted for miles driven before the first repair attempt

For a detailed breakdown of how the mileage offset is calculated, see our guide on how the mileage offset works.

Replacement

The manufacturer must provide a new vehicle that is substantially identical to the defective vehicle. The consumer should not have to pay anything additional for the replacement.

Cash-and-Keep Settlement

While not explicitly prescribed by the statute, cash-and-keep settlements are a common negotiated outcome where the consumer receives a cash payment and retains the vehicle.

Incidental and Consequential Damages

Consumers can recover all reasonable costs incurred as a result of the defect, including towing, rental cars, ride-share expenses, lost wages, and repair costs.

Civil Penalties: The Manufacturer’s Worst Nightmare

One of the Song-Beverly Act’s most powerful provisions is its civil penalty clause. Under California Civil Code Section 1794(c):

If the buyer establishes that the failure to comply was willful, the judgment may include a civil penalty which shall not exceed two times the amount of actual damages.

This means that if a manufacturer willfully refuses to repurchase or replace a vehicle that qualifies as a lemon, the consumer can recover up to three times their actual damages (the actual damages plus a penalty of up to two times the actual damages).

What Constitutes “Willful” Failure?

Courts have interpreted “willful” to mean that the manufacturer knew or should have known the vehicle qualified for repurchase but refused to act. Evidence of willfulness may include:

The manufacturer received written notice of the defect and repair attempts but did not initiate a buyback
Internal manufacturer documents showing awareness of a widespread defect
The manufacturer’s own repair records confirming the repair-attempt thresholds were met
The manufacturer offering a lowball settlement far below the vehicle’s value

Civil penalties are a powerful deterrent and a significant motivator in settlement negotiations. When a manufacturer knows it faces potential triple damages, it is far more likely to offer a fair settlement.

Attorney’s Fees: Why Hiring a Lawyer Costs You Nothing

California Civil Code Section 1794(d) provides that a prevailing buyer in a Song-Beverly Act case is entitled to recover reasonable attorney’s fees and costs. This provision is what makes the entire lemon law system work for consumers.

Because the manufacturer must pay your attorney’s fees if you win, you can hire a qualified lemon law attorney at no out-of-pocket cost. At Lion Lemon, we work on this basis — you pay nothing unless we recover compensation for you, and even then, the manufacturer pays our fees separately.

This fee-shifting provision also levels the playing field. Without it, manufacturers could simply outspend consumers in litigation, knowing that the cost of hiring an attorney would exceed the value of most claims. By requiring the manufacturer to pay attorney’s fees, the Act ensures that every consumer can afford to enforce their rights.

The Song-Beverly Act vs. Federal Lemon Law (Magnuson-Moss)

California consumers have protection under both the state Song-Beverly Act and the federal Magnuson-Moss Warranty Act (15 U.S.C. Sections 2301–2312). While both laws address warranty issues, the Song-Beverly Act is generally stronger and more consumer-friendly:

Feature	Song-Beverly Act	Magnuson-Moss Act
Scope	California purchases/leases	Nationwide
Civil penalties	Up to 2x actual damages	Not available
Attorney’s fees	Yes, for prevailing buyer	Yes, for prevailing consumer
Lemon law presumption	Yes (Section 1793.22)	No
Implied warranty protection	Cannot be disclaimed	Limited disclaimers allowed
Filing in state court	Yes	Yes, but must meet federal requirements for federal court

In practice, California lemon law attorneys often assert claims under both the Song-Beverly Act and the Magnuson-Moss Act. This provides maximum leverage and ensures all available remedies are preserved.

How the Song-Beverly Act Applies to Specific Situations

Used Vehicles

The Song-Beverly Act can protect used vehicle buyers if the vehicle was still covered by the original manufacturer’s warranty when the defect first appeared. Vehicles sold “as-is” without any warranty are generally not covered unless the seller is a dealer and implied warranty protections apply. For a complete analysis, see our guide on lemon law vs. used car warranty protections.

Leased Vehicles

The Act applies equally to purchased and leased vehicles. Lessees have the same rights to a refund (of lease payments), replacement, or cash settlement. See our detailed guide on lemon law for leased vehicles.

Electric and Hybrid Vehicles

EVs and hybrids are fully covered. Common qualifying defects include battery degradation, charging system failures, electric motor issues, and software glitches. Manufacturers like Tesla, Nissan (Leaf), Chevrolet (Bolt), and Hyundai (Ioniq) have all faced lemon law claims related to EV-specific defects.

Motorcycles and RVs

The Song-Beverly Act covers motorcycles and recreational vehicles sold with a manufacturer’s warranty. The same repair-attempt thresholds and remedies apply.

Non-Vehicle Consumer Goods

For consumer goods other than vehicles (appliances, electronics, etc.), the Song-Beverly Act requires the manufacturer to repair defects within 30 days of the consumer’s request. If the repair is not completed within 30 days, the consumer may return the product for a refund or replacement (California Civil Code Section 1793.2(d)(1)). Civil penalties and attorney’s fees are available for these claims as well.

Manufacturer Obligations Under the Act

The Song-Beverly Act imposes several affirmative obligations on manufacturers selling products in California:

Service and Repair Facilities

Manufacturers must maintain sufficient service and repair facilities reasonably close to all areas where their products are sold (California Civil Code Section 1793.2(a)(1)). If they choose not to maintain their own facilities, they must contract with independent repair providers.

Parts Availability

Manufacturers must make replacement parts available to authorized service facilities for a reasonable period after the product is sold. A repair should not be delayed because the manufacturer failed to stock parts.

Written Warranty Requirements

All express warranties must clearly disclose:

What is covered and what is excluded
The duration of the warranty
The procedure for obtaining warranty service
The identity of the warrantor

Disclosure of Known Defects

While the Song-Beverly Act does not explicitly require manufacturers to disclose all known defects, failure to do so can support a claim of willful noncompliance, triggering the civil penalty provision.

Filing Deadlines and the Statute of Limitations

Claims under the Song-Beverly Act are subject to a four-year statute of limitations under California Code of Civil Procedure Section 337 (for breach of written warranty) or Section 338 (for breach of implied warranty). The clock starts when the breach occurs — typically when the manufacturer fails to repair the defect after a reasonable number of attempts.

How to Enforce Your Rights Under the Song-Beverly Act

Step 1: Document Everything

Keep repair orders, communication records, photos, and financial records. Our documentation guide provides a step-by-step checklist.

Step 2: Consult a Lemon Law Attorney

An experienced attorney can evaluate your case, determine which provisions of the Act apply, and calculate your potential recovery — including civil penalties.

Step 3: Demand Letter

Your attorney sends a formal demand to the manufacturer, citing the specific Song-Beverly Act provisions that have been violated.

Step 4: Negotiation or Litigation

Most cases resolve through negotiation. If the manufacturer refuses to offer fair compensation, your attorney files a lawsuit. The manufacturer pays your attorney’s fees if you prevail.

Why the Song-Beverly Act Matters

The Song-Beverly Consumer Warranty Act represents California’s commitment to protecting consumers against manufacturers who sell defective products and refuse to stand behind their warranties. Its combination of mandatory repair obligations, strong remedies (refund, replacement, or cash settlement), civil penalties for willful violations, and attorney’s fees for prevailing consumers creates a system where manufacturers have every incentive to resolve legitimate claims quickly and fairly.

Without the Song-Beverly Act, consumers would be left with expensive, slow breach-of-contract claims under the UCC — a system that overwhelmingly favors manufacturers. The Act levels the playing field and ensures that every California consumer, regardless of income or legal sophistication, can enforce their warranty rights.
