Which vehicles does California's lemon law actually cover?

Before you count repair visits or days in the shop, there is a simpler question: is your vehicle the kind California's lemon law covers? The answer decides whether the strongest remedy, a manufacturer buyback or replacement, is even on the table. It turns on a handful of definitions in the Song-Beverly Consumer Warranty Act, and most of them are clearer than people expect.

This guide walks through what vehicles are covered by the lemon law in California, one category at a time: new cars, demonstrators and dealer cars, certified pre-owned and other used cars, leases, business and fleet vehicles, motorhomes, motorcycles and off-road vehicles, and cars bought by members of the military outside California. It is general information as of October 2026, not legal advice about your vehicle.

The basic test: a "new motor vehicle" bought or leased in California

The lemon law's buyback rule in Civil Code § 1793.2(d)(2) applies to a "new motor vehicle." That term is defined in Civil Code § 1793.22(e)(2), the Tanner Consumer Protection Act. In plain terms, it covers a new vehicle that was bought or used mainly for personal, family or household purposes, plus some vehicles used for business, which we explain below.

Three more conditions sit around that definition:

• It must have a manufacturer's express warranty. The claim is that the manufacturer could not make the vehicle match its own written warranty after a reasonable number of tries.
• The defect must matter. The statute calls it a "nonconformity": a problem that substantially impairs the vehicle's use, value or safety.
• It must have been bought in California, with one exception for service members. In Cummins, Inc. v. Superior Court (2005), the California Supreme Court held that the Act's refund-or-replace provisions do not reach a vehicle bought outside California, even when the owner lives here and the repairs happened here.

Cars, trucks, SUVs and vans for personal use

This is the core of the law. A new car, pickup, SUV or van that you bought or leased mainly for personal or family use is covered. The Department of Consumer Affairs' lemon law Q&A lists "cars, pickup trucks, vans, and SUVs" as covered.

If your vehicle fits here, the next questions are about the repair history. Our guide on how many repair attempts make a car a lemon covers the presumption: within 18 months or 18,000 miles, two attempts for a defect likely to cause death or serious bodily injury, four attempts for the same problem, or more than 30 days out of service. Direct notice to the manufacturer is required for the first two only when the warranty materials clearly disclose that requirement.

Demonstrators and dealer-owned cars

Section 1793.22(e)(2) goes on to name "a dealer-owned vehicle and a 'demonstrator' or other motor vehicle sold with a manufacturer's new car warranty." A demonstrator is a vehicle a dealer used to show customers how the model drives.

In Rodriguez v. FCA US, decided October 31, 2024, the California Supreme Court read that phrase as referring to vehicles like these, which get a new car warranty when they are sold, rather than every used car with warranty time left. If you bought a "demo" or a dealer-registered car, keep the window sticker and ask a dealer to print the warranty start date for your VIN. If the warranty began on your purchase date, that is strong evidence your vehicle qualifies.

Certified pre-owned and other used cars

Used cars are where many websites are now out of date. Before Rodriguez, many buyers of used cars that still had factory warranty time left were treated as covered by the buyback rule. The Supreme Court rejected that reading. Most used cars, including many sold with time left on the original warranty, are now outside the buyback remedy unless a manufacturer's new car warranty was issued with your sale.

That does not mean used car buyers have no rights. A dealer that gives its own written warranty on a used car carries implied warranty duties under Civil Code § 1795.5, the remaining factory warranty is still a promise to repair, and the federal Magnuson-Moss Warranty Act lets buyers sue for breach of a written warranty and recover attorney's fees. Certified pre-owned warranties need a close look, because the answer can turn on the exact warranty booklet. Our used car lemon law guide covers all of this, including the new three-day right to cancel for used cars priced at $50,000 or less that took effect October 1, 2026.

Leased vehicles

A lease counts. The Song-Beverly Act defines a "lessee" as an individual who leases consumer goods under a lease, and the Department of Consumer Affairs lists vehicles "purchased or leased" for personal or business use as covered. When a leased vehicle is bought back, the refund is figured differently, because you did not pay the full price: it generally covers what you paid under the lease, and the manufacturer pays off the leasing company. Our leased car lemon law guide explains the math and what to do before your lease ends.

Business and fleet vehicles: the five-vehicle, 10,000-pound rule

Section 1793.22(e)(2) also covers a new motor vehicle with a gross vehicle weight under 10,000 pounds that is bought or used primarily for business purposes by a person or entity, including a partnership, LLC or corporation, to which not more than five motor vehicles are registered in California.

Two numbers do the work:

• Weight. The test is gross vehicle weight under 10,000 pounds. Some heavy-duty trucks exceed it. Check the weight rating on the label in the driver's door jamb, not the curb weight.
• Fleet size. The business, counted as the person or entity the vehicles are registered to, can have no more than five motor vehicles registered in California. A contractor with three trucks qualifies; a company with twelve generally does not.

A vehicle bought for personal use does not have to meet these limits, even if you sometimes use it for work. And a sole proprietor who buys a truck mainly for personal use may fit the personal-use definition instead. Who the vehicle is registered to can decide the question.

Motorhomes: the chassis is covered, the living quarters are not

A motorhome is two products built by two companies: a chassis (engine, transmission, frame, steering, brakes) from one manufacturer, and the coach or "house" built on top by another. The lemon law treats them differently. Section 1793.22(e)(2) includes "the chassis, chassis cab, and that portion of a motor home devoted to its propulsion," but not any portion designed, used or maintained primarily for human habitation.

So a transmission that keeps failing or a steering defect may support a motor-vehicle lemon claim against the chassis manufacturer. A leaking roof, slide-outs that will not retract, or a refrigerator that keeps failing are not part of the "new motor vehicle." Those parts are often covered by the coach manufacturer's separate warranty, and claims about them may proceed under other warranty laws, such as the Song-Beverly Act's general rules for consumer goods or federal warranty law, without the motor-vehicle presumption.

The out-of-state purchase rule matters here too. The Cummins case involved a motorhome that California residents bought while visiting Idaho, and the Supreme Court held the refund-or-replace provisions did not apply.

Motorcycles and off-road vehicles

The definition expressly excludes them. Section 1793.22(e)(2) "does not include a motorcycle" or a motor vehicle that is not registered under the Vehicle Code because it is to be operated or used "exclusively off the highways." That covers many dirt bikes, off-road side-by-sides and similar machines.

Exclusion from the motor-vehicle definition does not mean a motorcycle or off-road vehicle has no warranty protection. The Song-Beverly Act also has general rules for "consumer goods," meaning new products bought primarily for personal, family or household use, and the federal Magnuson-Moss Warranty Act applies to written warranties on consumer products. Those routes do not carry the 18-month presumption or the vehicle-specific restitution formula, so the claim looks different.

Bought outside California while serving in the military

Service members get a specific exception to the in-state purchase rule. Under Civil Code § 1795.8, the lemon law can apply to a member of the Armed Forces who buys a motor vehicle with a manufacturer's express warranty in the United States, from a manufacturer that sells motor vehicles in California or its agent or representative, if the service member was stationed in or a resident of California either when the vehicle was bought or when the lawsuit is filed.

Three points are worth noting. The text says "member of the Armed Forces"; it does not use the words "active duty." Either timing works: stationed or resident here at purchase, or at filing. And the vehicle still has to meet the "new motor vehicle" definition. If you bought a car at a dealer near a base in another state and were then stationed in California, keep your orders and your purchase contract.

Quick checklist: is your vehicle covered?

1. Was it bought or leased in California, or are you a service member who fits § 1795.8?
2. Was it new, a demonstrator or dealer-owned car, or a vehicle sold with a manufacturer's new car warranty starting at your sale?
3. Was it bought mainly for personal or family use, or by a business with five or fewer vehicles registered in California and a gross vehicle weight under 10,000 pounds?
4. Is the problem in a covered part (for a motorhome, the chassis or drivetrain rather than the living area)?
5. Did the problem start while the manufacturer's warranty was in effect?

If you answered yes to all five, the next questions are repair history and timing. Try our "does my car qualify" tool, and check the filing deadline: for manufacturers that opted in to the 2025 procedures it can be as short as one year after the warranty expires, as our AB 1755 guide explains. For manufacturers that did not opt in, the deadline is generally four years under the Commercial Code's warranty statute of limitations, and tolling rules can apply. Either way, call promptly.

How LaCour reviews coverage questions

Coverage is often the first thing a manufacturer contests, especially for demos, business trucks and motorhomes. Our California lemon law team reads the paperwork first: purchase contract, registration, warranty booklet and repair orders. We will tell you plainly if your vehicle falls outside the buyback rule, and what other warranty claims remain. Reviews are free, in English or Spanish, and when a lemon law claim succeeds the manufacturer pays the attorney's fees.
