What voids a caravan warranty
The conditions written in your own booklet.
The conditions that appear most often are the scheduled services, the van's ratings, modifications, and the maintenance the booklet puts on you.

Your own warranty booklet sets the conditions, and the ones that appear most often are the services, the van's ratings and modifications.
Your consumer guarantees under Australian Consumer Law are separate, automatic, and can apply after a warranty expires.
- Services - on time, at your booklet's interval, and recorded (the condition worth finding first in your own warranty booklet)
- Ratings - load and tow inside what the van is built for (weights are checkable after the fact, so keep a weighbridge ticket)
- Modifications - ask the manufacturer in writing, before anything is fitted (then keep the reply, the invoice and every compliance certificate)
The three covers on a caravan
A caravan carries three separate covers: the builder's warranty, the appliance warranties, and your consumer guarantees under the Australian Consumer Law. They have different owners and they fail in different ways.
The manufacturer's warranty
This is the builder's own promise, written in the warranty booklet that came with the van. It sets what is covered, for how long, what you have to do to keep it, and how a claim is made. Two vans in the same yard can carry very different versions of it. The booklet in your own folder is the one that describes your van.
The appliance warranties
The fridge, the air conditioner, the hot water system, the washing machine and the electronics carry their own warranties from the companies that made them. Each has its own terms and often its own registration. That is why a fault inside the van sometimes gets handled by a different business from the one that built it.
Your consumer guarantees
These come from the Australian Consumer Law rather than from anyone's booklet. The ACCC states that consumer guarantees apply to caravans and other recreational vehicles. They are separate to any manufacturer's warranty, and they may still apply after it has expired. They are automatic and cannot be taken away by a warranty term or a sign on a wall.
What the ACCC says, in its own words
Consumer guarantees are automatic and cannot be taken away, and a warranty is an extra promise a business chooses to make on top of them. Consumer guarantees apply to caravans, they are separate to any manufacturer's warranty, and they may still apply once that warranty has expired. A supplier cannot avoid responsibility by pointing at a third party's warranty instead.

Where a claim is usually decided
These are the mechanics an owner controls. Each one comes with the same two jobs: read what your booklet asks, and keep the evidence that you did it.
1. Services missed, late, or done and never recorded
Warranties often depend on the scheduled services being done and recorded. That makes the service history the first thing anyone looks at in a claim. Builders commonly set the first service at 1,000km or three months, whichever comes first, then annually or every 10,000km. The interval in your own booklet is the one that binds you.
Check: Find the interval, whether a particular kind of workshop must do the work, and what evidence the booklet asks for.
Keep: The stamped logbook and the itemised invoice for every service, including the ones you paid for yourself.
2. Using the van beyond what it is rated for
Every caravan is built to a set of numbers: an ATM, a tow ball mass, an axle load and, on a lot of vans, a description of the surfaces it is designed for. Loading past those numbers, or towing the van somewhere it was not built to go, causes damage that shows afterwards. This is also the point where a warranty question and an insurance question arrive together, because both contracts care about the same weights.
Check: Read what the booklet says about loading, about tow vehicle requirements and about any restriction on where the van may be taken.
Keep: A weighbridge ticket for the van loaded the way you really load it, so the weights are a fact rather than an opinion.
3. Modifications, and who fitted them
Solar, lithium, inverters, suspension changes, chassis work, extra water tanks and bull bars all change the van from what left the factory. Before anything is fitted, ask the manufacturer in writing what that modification does to your warranty, and keep the answer. Gas and 240 volt work is a separate matter. By law it must be done and certified by the appropriately licensed trade.
Check: Ask, in writing, before the work is booked. A written answer costs nothing and settles the question.
Keep: The manufacturer's reply, the installer's invoice, the specification of what was fitted, and every gas and electrical compliance certificate.
4. Water, and the maintenance that turns out to be yours
Water getting into the structure is one of the costliest faults a caravan can have. It is slow and easy to miss until a floor feels soft. Sealant around windows, hatches, the roof joins and the awning rail wears out over time. A booklet will usually say how often it wants the seals checked, and by whom.
Check: Find the sealant and roof inspection interval, and whether a particular kind of workshop must do or sign off the work.
Keep: A dated record of every seal inspection and every reseal, with photos, the same way you keep service invoices.
5. The jobs owners do not know are theirs
A caravan needs a handful of owner tasks that a car never does. Wheel nuts need re-tightening after a wheel has been fitted, and the published schedules treat that as a sequence rather than a single job. Wheel bearings want inspecting and repacking on an interval. Tyres age on the calendar. Brakes need adjusting. None of it is difficult, and a technician can see when it was not done.
Check: Read the maintenance schedule in the booklet from front to back once, and diarise anything with an interval on it.
Keep: A single notebook or note on your phone with the date of every check you do yourself.
A warranty claim and an insurance claim are different contracts
They care about some of the same things, weights especially. But different businesses answer them under different rules, and one saying no tells you nothing about the other. What voids an insurance claim is a separate subject, covered in our caravan insurance guide.
What to find in your own warranty booklet
Do this once, before anything goes wrong, and write the answers on the inside cover. Every one of them is a line in the document you already own.
- The start date, and exactly what event started it.
- Whether the van has to be registered with the builder for the cover to run, and whether that was done.
- What is covered structurally, and what sits outside it.
- The service interval, and what evidence of servicing is required.
- Who may carry out the scheduled work.
- The maintenance the booklet puts on you, especially sealant and roof inspections, and how often.
- What has to be disclosed or approved before a modification is fitted.
- How a claim is made, who it goes to first, and how long they have to respond.
- Whether the cover transfers if you sell the van, and what has to happen for it to.
If you are buying used and expect the balance of a warranty to come with the van, ask the manufacturer, not the seller. Get the answer in writing before you pay, as covered in buying privately against buying from a dealer.
If a claim is knocked back
Get everything into writing, including the refusal and the reason given for it. A phone call that nobody wrote down is the weakest position to argue from, and an email costs nothing.
Gather what you already have: the booklet, the service invoices, the compliance certificates, the dated photographs and the weighbridge ticket. Most warranty disputes are decided by which side can show what happened and when.
Then look at the problem again under the Australian Consumer Law. Those rights are separate from the warranty and do not depend on the booklet. If it is still not resolved, take it to your state or territory consumer protection agency. The ACCC publishes what the guarantees cover.
General information, not legal advice
This page shows where the conditions sit, so you can read your own paperwork with the right questions. Your warranty booklet governs your warranty, and the Australian Consumer Law governs your guarantees. For a dispute over real money, talk to your state or territory consumer protection agency or a qualified adviser.
If the builder goes bust
If you bought the van from a dealer or another business, your consumer guarantees are with that business. They still apply if the builder goes into administration or liquidation. That business answers for the van being of acceptable quality, but not for the builder's own warranty.
If you bought the van straight from the builder, the builder was the seller. A claim then goes to its administrator or liquidator.
The builder's warranty is a promise from that company. If the company goes into administration or liquidation, an administrator or liquidator is appointed. They decide whether warranty work continues. You usually lodge a warranty claim with them. Read their notices and ask them your questions in writing.
Appliances such as the fridge, air conditioner and hot water system may carry their own maker's warranty. Some parts, such as the suspension and brakes, may too. Check each booklet for how to claim. Keep the booklets with the list of what was fitted to your van.

Caravan warranty questions, answered
What voids a caravan warranty in Australia?
The conditions in your warranty booklet decide it, most often recorded services, staying within the ratings, approved modifications and owner maintenance. Your consumer guarantees under the Australian Consumer Law are separate and automatic.
Does modifying a caravan void the warranty?
Your booklet and the manufacturer decide that for each modification. Ask in writing before the work is booked, and keep the reply with the installer's invoice.
Do I have to service my caravan at the dealer I bought it from?
Check the booklet, because this condition differs a lot from builder to builder. If it is not clear, ask the manufacturer in writing and keep the answer with the logbook.
Is a caravan warranty transferable to the next owner?
Some transfer, some transfer with conditions and some do not. Ask the builder directly, in writing, before you pay.
What can I do if a warranty claim is refused?
Put the claim and the refusal in writing, and gather the booklet, service invoices, photographs and dates. Then check your consumer guarantees under the Australian Consumer Law, and take any unresolved claim to your state or territory consumer protection agency.
What happens to my caravan warranty if the builder goes bust?
The builder's warranty is a promise from that company. If the company goes into administration or liquidation, an administrator or liquidator decides whether warranty work continues. If you bought from a dealer or another business, your consumer guarantees are with that business and still apply. That business answers for the van being of acceptable quality, but not for the builder's own warranty.
Does water damage get covered by a caravan warranty?
The cause decides it, along with the sealant maintenance your booklet puts on you. Keep dated records of every seal check and reseal as evidence.
Read the booklet before you need it
An hour with your own warranty document, a diary entry for the service, and a folder for the invoices is the whole job.
