When a new motorhome spends its first season at the dealer instead of on the road, owners want to know whether California's motorhome and RV lemon law applies. It does, in two pieces. The part of the coach that moves you down the highway is treated as a "new motor vehicle." The part you live in is treated as a consumer product. Both can lead to a refund, but the rules and the companies responsible differ.
Our guide to what vehicles the lemon law covers gives the short version. This page goes deeper: the statutory split, the two warranties, travel trailers, Indiana forum clauses and how to document repairs on a vehicle that barely fits in a service bay. General information as of October 2026, not legal advice.
The statutory split: propulsion versus habitation
California's buyback rule for vehicles, Civil Code § 1793.2(d)(2), applies to a "new motor vehicle" as defined in Civil Code § 1793.22(e)(2). That definition includes "the chassis, chassis cab, and that portion of a motor home devoted to its propulsion," and leaves out any portion "designed, used, or maintained primarily for human habitation." The same section, in subdivision (e)(3), defines a motor home as a vehicular unit built on or permanently attached to a self-propelled chassis, chassis cab or van, which becomes an integral part of the completed vehicle and is designed for human habitation for recreational or emergency occupancy.
That covers Class A coaches, Class C motorhomes and Class B camper vans. The Department of Consumer Affairs lists "the chassis, chassis cab, and drive train of a motor home" as covered. Think of two zones:
- Propulsion zone: engine, transmission, drive axle, steering, brakes, suspension, frame, the chassis electrical system and the dashboard. Defects here can support a vehicle lemon law claim, with the 18-month presumption and the vehicle restitution formula.
- Habitation zone: roof, walls and seals, slide-outs, leveling jacks, plumbing and tanks, the house battery and converter, generator, furnace, roof air conditioning, refrigerator and cabinetry. Defects here fall outside the "new motor vehicle" definition, but they are not unprotected.
Some defects sit on the line, such as a coach-installed component that drains the engine battery. Where a problem falls is a factual question, and the repair orders usually decide it.
Living-quarters defects: the consumer goods route
The living quarters are "consumer goods" under the Song-Beverly Consumer Warranty Act. Civil Code § 1791(a) defines consumer goods as "any new product or part thereof" used, bought or leased primarily for personal, family or household purposes. For goods like these, § 1793.2(d)(1) says that if the manufacturer or its representative in California cannot conform them to the express warranty after a reasonable number of attempts, the manufacturer must replace the goods or reimburse the purchase price, less an amount directly attributable to use "prior to the discovery of the nonconformity."
The same subdivision adds a rule written for RV owners. For a travel trailer or "a portion of a motor home designed, used, or maintained for human habitation," the buyer is free to elect reimbursement instead of a replacement. In other words, the coach maker cannot insist on handing you another coach.
A California appellate court applied this route in National R.V., Inc. v. Foreman (1995). The buyers reported 25 defects, including a failing electrical converter, a water pump problem and stalling that cut power steering and braking. The Court of Appeal held that the coach is a consumer good subject to the Act's general replace-or-refund rule, even though it is excluded from the vehicle lemon law provision. The jury had awarded $96,000 in damages and a $115,200 civil penalty against the coach maker, and the judgment was affirmed. Every case is different, and past results do not predict the outcome of any other case.
This route does not give you the Tanner Act presumption or the vehicle restitution formula with its 120,000-mile offset. The question is simply whether the manufacturer had a reasonable number of attempts. The penalty and fee provisions of Civil Code § 1794 still apply: a buyer who prevails may recover attorney's fees and costs, and a willful violation can support a civil penalty of up to two times actual damages.
Two manufacturers, two warranties
Most motorhomes arrive with at least two written warranties. The chassis maker warrants the chassis and powertrain. The coach maker warrants what it built. A Thor Motor Coach limited warranty filed with NHTSA in a 2024 investigation, a 2016 edition, shows how this works in practice: it ran 12 months or 15,000 miles, a separate structural warranty ran 24 months or 24,000 miles, and it excluded "the automotive chassis and power train," which the chassis manufacturer covers under its own warranty (NHTSA file PE24023). Your booklets may differ, so read both.
Three consequences follow:
- The right defendant depends on the defect. A chassis buyback claim runs against the chassis maker. A coach claim runs against the coach maker. Defects in both can involve both.
- The clocks differ. A coach warranty can be much shorter than a chassis warranty. Report coach defects in writing early and keep proof.
- The repair shops differ. Chassis work is often done by the chassis brand's truck dealer, coach work by an RV dealer. Both records count.
Indiana forum clauses in RV warranties
Many RVs are built in Indiana, and some RV warranties say any lawsuit must be filed there under Indiana law. In Lathrop v. Thor Motor Coach, published October 7, 2024, involving a motorhome bought in Santa Fe Springs, the Court of Appeal held that the company enforcing the clause had to show that litigating in Indiana would not diminish the buyers' unwaivable California rights, and that the company's offer to apply California law in Indiana did not meet that burden. The clause was not enforced.
The California Supreme Court agreed to review the case, and as of a July 2026 report by Consumer Watchdog it was still pending. If your warranty names another state's courts, do not assume you must sue there.
Travel trailers, fifth-wheels and other towables
A towable has no engine, so it is never a "new motor vehicle," but owners still have remedies. A new travel trailer bought for personal use is a consumer good, and § 1793.2(d)(1) names travel trailers specifically: if the manufacturer cannot fix a warranty defect after a reasonable number of attempts, you may choose a refund instead of a replacement. Whether a fifth-wheel or toy hauler is treated as a "travel trailer" under that sentence can depend on how it is classified, but the general replace-or-refund rule for consumer goods applies either way.
The federal Magnuson-Moss Warranty Act is a second route for any towable or motorhome sold with a written warranty. It lets a consumer sue for breach of the warranty and recover attorney's fees if the consumer finally prevails. Its refund-or-replace rule in 15 U.S.C. § 2304 applies only to warranties labeled "full," and many RV warranties are labeled "limited."
Recalls on motorhomes
The coach builder usually files its own recall reports with NHTSA, separate from the chassis maker. Two examples:
- Recall 22V-094 (Thor Motor Coach). Covered 731 gas-powered 2020–2021 Omni and Magnitude motorhomes. The report says propane lines were routed through the rear suspension leaf springs, where they could rub and leak. Dealers re-routed them (NHTSA recall report).
- Investigation PE24023 (Thor and Lippert). NHTSA looked into hitch receivers that may crack on an estimated 3,091 2016–2022 motorhomes. It closed the probe in January 2026 after a free inspection-and-repair campaign, without finding a defect (opening resume; closing resume).
Search your own coach and chassis with our recall and complaint lookup. A recall alone does not make an RV a lemon, but repeated recall repairs that do not fix the problem belong in your repair history.
Building an RV repair record that holds up
RV cases often turn on paperwork, because repair delays are long and work is split across shops.
- Get a repair order every time. Under § 1793.2(b), warranty repairs must be completed within 30 days unless you agree otherwise in writing, with extensions for delays beyond the manufacturer's control. Each order should show dates in and out, mileage, your complaint and what was done.
- Separate chassis and coach complaints. Ask the shop to list each problem on its own line. Chassis days out of service matter for the vehicle presumption, and the chassis maker may argue that time spent fixing the coach does not count toward its 30 days.
- Use the "too big to deliver" rule. Section 1793.2(c) says that when goods cannot reasonably be delivered to a repair facility "due to reasons of size and weight, or method of attachment," or the nature of the defect, written notice to the manufacturer counts as delivery. The manufacturer then chooses to repair at your location, pick the goods up or arrange transport, and generally pays reasonable transport costs. If no shop near you can take a large coach, put that in writing.
- Write to both manufacturers. List the defects and repair dates in a short letter to each, and keep proof of delivery.
- Photograph and film. Date-stamped video is often the best proof of an intermittent problem.
- Keep the purchase file together. Contract, both warranty booklets, window sticker, service contract and receipts for trips cut short. Our lemon law documents checklist has a printable list.
For a chassis claim, our guide on how many repair attempts make a vehicle a lemon explains the presumption in detail.
Deadlines and where you bought it
First, purchase location: in Cummins, Inc. v. Superior Court (2005), the California Supreme Court held that the vehicle refund-or-replace rules did not apply to a motorhome California residents bought in Idaho. Service members have a separate rule under Civil Code § 1795.8.
Second, the filing deadline. If the chassis maker opted in to California's 2025 lemon law procedures, a vehicle buyback claim may face a shorter deadline, generally one year after the warranty expires, as our AB 1755 guide explains. Otherwise, warranty claims are generally subject to the Commercial Code's four-year warranty statute of limitations, and tolling rules can apply. Because coach warranties are short, call promptly.
How LaCour reviews motorhome cases
We start by sorting your repair orders into chassis and coach problems and matching each to the right warranty. Our California lemon law team reviews RV and motorhome cases for free, in English or Spanish, and the Song-Beverly Act lets a buyer who prevails recover attorney's fees and costs from the manufacturer.
Frequently asked questions
Does California's lemon law cover motorhomes?
Yes, in part. The chassis, chassis cab and the part of a motorhome devoted to propulsion count as a "new motor vehicle" under Civil Code § 1793.22(e)(2). The living quarters are excluded from that definition, but they are consumer goods covered by the Song-Beverly Act's general replace-or-refund rule.
Can I get a refund if my RV's slide-outs and roof keep failing?
Possibly. Under Civil Code § 1793.2(d)(1), if the coach maker cannot fix a warranty defect after a reasonable number of attempts, it must replace the goods or reimburse the price less a use deduction. For the living portion of a motorhome, the buyer may choose reimbursement instead of a replacement.
Is a travel trailer covered by the lemon law in California?
A travel trailer is not a motor vehicle, but a new one bought for personal use is a consumer good under the Song-Beverly Act. Section 1793.2(d)(1) names travel trailers and lets the buyer elect a refund instead of a replacement when a warranty defect cannot be fixed after a reasonable number of attempts.
Who do I sue, the chassis maker or the motorhome maker?
It depends on the defect. Engine, transmission, steering and brake problems generally run to the chassis manufacturer's warranty. Living-area problems run to the coach maker. Keep repair orders that describe each problem separately.
My RV warranty says I have to sue in Indiana. Is that true?
Not necessarily. In Lathrop v. Thor Motor Coach (2024), a California Court of Appeal refused to enforce an Indiana forum clause because the manufacturer did not show California buyers' unwaivable rights would be protected. The California Supreme Court is reviewing that decision.
What if no repair shop can fit my motorhome?
Civil Code § 1793.2(c) covers goods that cannot reasonably be delivered because of size, weight or the nature of the defect. Written notice to the manufacturer then counts as delivery, and the manufacturer must repair on site, pick up the goods or arrange transport.
