California RV Lemon Law: Your Rights as a Motorhome, Trailer, or Fifth Wheel Owner

RVs are complicated machines — drivetrain, generator, plumbing, slide-outs, leveling systems, awnings, electrical, propane, and house batteries all in one rolling unit. When something keeps breaking and the dealer can't fix it, California's lemon law (the Song-Beverly Consumer Warranty Act, Cal. Civ. Code §§ 1790-1795.8) gives RV owners powerful rights most never hear about. This guide explains exactly how the law applies, what you can recover, and what to do today.

Does California's lemon law apply to RVs?

Yes — to the components covered by a written warranty. This is the part that surprises owners. An RV is treated as a hybrid: the chassis and drivetrain are usually warranted by one manufacturer (Ford, Freightliner, Mercedes Sprinter, Cummins), and the coach/house portion is warranted separately by the RV builder (Thor, Forest River, Winnebago, Tiffin, Newmar, Jayco, Grand Design, Keystone, etc.).

Song-Beverly applies to consumer goods sold with a written warranty in California, which covers:

• Class A, B, and C motorhomes — both gas and diesel
• Travel trailers and fifth wheels
• Toy haulers
• Camper vans and truck campers sold with a written warranty
• Slide-out, leveling, generator, inverter, refrigerator, A/C, and water system components when warranted

It does not apply to fully off-warranty private-party sales with no written warranty.

What problems qualify?

A defect qualifies when it substantially impairs the use, value, or safety of the RV and persists after a reasonable number of repair attempts. The most common qualifying issues we see:

• Slide-out failures — won't extend/retract, leaks, motor burnouts, repeated alignment problems
• Chassis and drivetrain — transmission slipping, engine stalling, DEF/regen failures on diesel pushers, no-starts
• House electrical — inverter failures, repeated battery drains, shore-power faults, generator that won't auto-start or fault-trips
• Plumbing and tanks — leaks, tank sensors that never read correctly, pump failures
• Leveling and jacks — jacks that won't retract, leveling that throws errors mid-trip
• Roof and delamination — sidewall flex, water intrusion, sealed seams that keep failing
• HVAC — A/C units that ice up or won't cool, furnace ignition failures
• Safety systems — brake faults, ABS warnings, ADAS faults on newer Class A and Super C units

If the dealer has tried 2+ times for a safety defect, 4+ times for a non-safety defect, or your rig has been out of service 30+ cumulative days, the Tanner Act presumption (Cal. Civ. Code § 1793.22(b)) likely applies.

What you can recover

You generally have two routes:

Buyback

The manufacturer refunds everything you paid — down payment, all monthly payments, sales tax, DMV fees, incidentals (towing, transport between dealerships, rental costs during long downtime) — minus a small mileage offset based on the miles at the first repair attempt. The manufacturer pays off your loan so it closes in good standing.

Cash-and-keep

Keep the RV and receive a lump-sum settlement. Common for owners who love the floorplan and can live with a defect that has been mostly resolved, or where the resale market is strong.

In both cases, attorney's fees are paid by the manufacturer under Cal. Civ. Code § 1794(d) — you owe nothing out of pocket. Willful violations open up a civil penalty of up to 2x your actual damages under § 1794(c), which gives manufacturers strong incentive to settle.

Your 5-step action plan

1. Stop guessing — start documenting

Every visit to the dealer or mobile tech must generate a written repair order (RO) describing the complaint, what was done, and the mileage/hour reading. Photograph each RO before you leave the lot. Photos and short videos of the defect (slide misalignment, generator fault codes, water intrusion) carry tremendous weight.

2. Pull the chain of warranties together

Identify the chassis manufacturer, the coach builder, and any separately-warranted appliances (Dometic, Norcold, Onan, Lippert, Cummins, Atwood). Each carries its own written warranty and each is a potential defendant. We sort this out for you — your job is just to keep paperwork.

3. Escalate through the right channels

Coach builders maintain customer-service escalation lines (Thor, Forest River, Winnebago, Tiffin, Newmar, etc.). Chassis issues should also be escalated to the chassis maker (Ford Customer Care, Freightliner, Mercedes). Polite written escalation creates a paper trail and sometimes triggers a free factory repair — but it does not reset your lemon law clock.

4. Get a free legal evaluation early

Most RV owners wait far too long. The earlier we engage, the easier it is to gather warranty-period ROs and the cleaner the legal posture. There is no cost to find out where you stand.

5. File the claim

If the case qualifies, we send a Song-Beverly demand to the manufacturer(s) and negotiate the buyback or settlement. RV cases tend to take 4-9 months because the defect chain is more complex than a passenger vehicle, but the recoveries are correspondingly larger — six-figure refunds are common on Class A diesel pushers.

Real examples

• 2023 Class A diesel pusher, $385,000 MSRP — repeated DEF/regen and air-suspension faults, 38 days out of service in year one. Full buyback, owner walked away with $58,000 net of payoff after 11 months of payments and a small mileage offset.
• 2022 fifth wheel, $98,000 — bedroom slide motor failed three times, sidewall delamination on the door side. Cash-and-keep settlement of $42,000; owner kept the trailer.
• 2024 Class B Sprinter conversion, $190,000 — DEF system stranded the owner twice on trips, dealer had it 47 days total. Buyback in 5 months.

Common misconceptions

• "My RV is too big for lemon law." No size cap exists. Class A motorhomes are explicitly covered.
• "I'm out of warranty." Coverage is determined by when the defect was first reported, not when you finally sue. If you reported it during the warranty period, you're protected.
• "The dealer told me it's normal RV stuff." Dealers say this constantly. It is rarely correct, and is never a legal defense to a Song-Beverly claim.
• "I bought it used." If the original factory warranty was still in effect when you bought it, or you received a written dealer warranty, you may still qualify.
