It is the question we get asked more than any other, usually in a slightly worried voice. No, we will not void your warranty. Here is why, and who says so.
Somewhere along the way, a very effective idea took hold: that a new car has to go back to the dealer for every service or the warranty disappears. It is repeated so often that most people simply accept it. Plenty of drivers spend years and a fair bit of money acting on it.
It is not true, and it has not been true for a long time. You are free to have your car serviced by any qualified, licensed workshop you choose, and the competition regulator has said so in writing. What follows is the real position, what does put a warranty at risk, and the part almost nobody explains, which is that your rights do not end even if a warranty is voided.
The short version
- No. Servicing at a qualified, licensed independent workshop does not void your new car warranty.
- The manufacturer’s schedule has to be followed and genuine or equivalent quality parts used.
- Even if a warranty is voided, your consumer guarantees under Australian Consumer Law still apply.

Does servicing at an independent mechanic void your new car warranty?
No. In Australia, having your vehicle serviced by a qualified, licensed independent workshop does not void your manufacturer’s warranty, provided the manufacturer’s service schedule is followed and genuine or equivalent quality parts are used.
This is the most persistent myth in the trade, and it is worth being clear about where the answer comes from. It is not a workshop’s opinion. It is the position of the Australian Competition and Consumer Commission.
What the ACCC actually says
The ACCC’s industry guidance on the Australian Consumer Law puts it plainly: “there is no requirement under the ACL for a vehicle to be serviced by a dealer for the consumer guarantees to apply”. The same guidance warns businesses off implying otherwise, telling them to “avoid misleading statements that consumers are required to service their vehicles at a dealer or they will void their rights”.
It goes further. The guidance notes that a manufacturer’s warranty which requires servicing at a dealer “may constitute anti-competitive conduct under the Competition and Consumer Act 2010”.
Separately, the ACCC confirms that consumers “can choose an independent repairer to service and repair their vehicle knowing it’s mandatory for car manufacturers to make service and repair information available”. That last point matters more than it sounds. Under the mandatory information sharing scheme, manufacturers have to make the same service and repair information available to independent workshops that they give their own dealers.
The four things that have to be right
Choosing your own workshop is your right. Keeping your warranty intact still depends on the work being done properly.
- The manufacturer’s schedule is followed for that specific vehicle and that specific interval, not a generic service package.
- The right parts go in, meaning genuine parts or parts built to the manufacturer’s specification.
- The service is recorded properly, in the physical logbook or the manufacturer’s digital service record.
- The workshop is properly licensed. In NSW, anyone running a vehicle repair business needs a motor vehicle repairer licence, and anyone carrying out the repair work needs a current motor vehicle tradesperson certificate.
That is the whole test. If you want to see what it looks like in practice, our general servicing page sets out what a service covers.
Warranty and consumer guarantees are two different things
A manufacturer’s warranty is a voluntary promise from the manufacturer with conditions attached. Consumer guarantees are automatic rights under Australian Consumer Law that apply no matter what any warranty says.
Most arguments about warranties happen because people do not know the second one exists. It is the single most useful thing to understand about new car warranty laws in Australia.
| Manufacturer’s warranty | Consumer guarantees | |
|---|---|---|
| Where it comes from | The manufacturer, voluntarily | Australian Consumer Law |
| Can it have conditions | Yes, and you have to meet them | No, they apply automatically |
| Can it be taken away | Yes, if you break the conditions | No, they cannot be negotiated away |
| How long it lasts | The stated term, for example five or seven years | A reasonable period, based on the price and what the vehicle should be capable of |
| Who you deal with | The manufacturer or dealer | The manufacturer or the business that sold you the vehicle |
Why this matters if you are ever told your warranty is void
The ACCC is explicit that even where a warranty has been voided, “the consumer still has their basic consumer guarantee rights, and can still ask the business to provide a remedy for a problem”.
In plain terms, “your warranty is void” is not the end of the conversation. It means one avenue has closed. A vehicle still has to be of acceptable quality, fit for purpose and free from defects for a reasonable time, and that obligation does not disappear because a service was late or an accessory was fitted.
What actually voids a new car warranty in Australia?
A warranty is put at risk when a condition of it is broken and a fault can be traced back to that. The usual culprits are servicing the vehicle yourself, letting service intervals slide badly, using the wrong parts or oil, and modifications that cause a failure.
Servicing it yourself
This is the quickest way to create a problem. Doing your own oil changes might satisfy the mechanical side, but there is no licensed workshop and no verifiable record standing behind the work. When a claim gets examined, that is exactly what gets asked for.
Letting service intervals slide
One service a little late is usually not fatal. A visible pattern of missed or badly overdue services is a different conversation, and it gives a manufacturer something concrete to point at. If you are behind, the fix is to get back on schedule and have it recorded rather than hope nobody notices.
The wrong parts or the wrong oil
Cheap servicing often means the wrong oil specification, and modern engines are far less forgiving about that than they used to be. Parts that do not meet the manufacturer’s specification sit in the same category. This is a legitimate warranty risk and it is entirely avoidable.
Bull bars, GVM upgrades and catch cans: where modifications sit
A modification does not automatically void your entire warranty. What it can do is affect the parts of the vehicle it relates to, if the manufacturer can show the modification caused the failure.
That distinction is where most of the fear comes from, and it is worth holding onto.
The accessories that come up most often out here in the Central West
Three come up repeatedly, and if you drive a ute or a 4WD around the Central West there is a fair chance you are running at least one of them:
- Bull bars. In some cases these can affect suspension warranty, because of the additional weight sitting out over the front axle.
- GVM upgrades. These commonly affect suspension warranty, since the upgrade changes the load the vehicle was designed and warranted to carry.
- Catch cans. A popular addition on diesels, and one that sits squarely in the aftermarket category unless the manufacturer offers its own.
Manufacturer branded accessories are usually the safe path
Most manufacturers sell their own accessory range, and those are generally covered and will not affect your warranty. If you want the modification and you want the certainty, that is the version to ask about. If you are going aftermarket, keep the paperwork showing what was fitted and who fitted it.
How a manufacturer decides a claim
The deciding question is whether the fault is connected to whatever the manufacturer is pointing at. A missed service or a fitted accessory only matters to a claim if it caused, or contributed to, the failure being claimed.
That is why blanket statements about warranties being void are so often wrong. If a trim clip lets go or a headrest is not bolted down properly, a late service six months ago has nothing to do with it. If a component failed in a way that a service would have caught and prevented, that is a different discussion and a much harder one to win.
It is decided case by case, by the manufacturer or the dealer, not by your workshop. What you can control is the quality of the record you can put in front of them.
What to keep on file
Keep three things, and keep them for as long as you own the vehicle.
- Your complete service record, either the stamped logbook or your manufacturer’s digital service record.
- Invoices for every service, showing what was done and which parts and oil went in. This is what proves the specification was met.
- Records of anything fitted to the vehicle, including who fitted it and when. If a modification ever comes up in a claim, the paperwork is what turns an argument into a fact.
Drivers who keep these rarely have trouble. Drivers who cannot produce any of them are negotiating from a much weaker position, whoever serviced the car. If you are not sure what state your records are in, send us an enquiry and we will take a look at your logbook with you.

FAQs
Does Australian Consumer Law override a manufacturer’s warranty?
It sits alongside it rather than overriding it. The practical difference most people miss is duration. A manufacturer’s warranty runs for a fixed term, while consumer guarantees run for whatever period is reasonable given what you paid and what that vehicle should be capable of. On an expensive vehicle that can stretch beyond the written warranty, which is why a fault that appears just outside the warranty term is still worth raising.
Does my warranty transfer if I sell the car?
Usually yes. Most manufacturer warranties in Australia run with the vehicle rather than the owner, so the balance of the term passes to the next buyer. Terms vary, so check your own warranty booklet, and note that some are conditional on the service history being complete. One more reason to keep the record straight even when you are close to selling.
Does a bull bar void my warranty?
Not the whole warranty. It can affect warranty on related components, most often suspension, if the manufacturer can show the extra weight caused the failure. Your engine, transmission and electronics are not affected by a bull bar sitting on the front of the vehicle.
Does tuning a car void the warranty?
It can affect the powertrain warranty specifically, if the manufacturer proves the tune caused the failure. It does not wipe out the warranty on the rest of the vehicle, and it does not affect your consumer guarantees. Reputable tuning keeps the factory software backed up so the vehicle can be returned to standard.
Do I have to use genuine parts to keep my warranty?
Not necessarily. Parts that meet or exceed the manufacturer’s specification are generally acceptable, which is a wider field than the genuine range. Where a genuine part is available and sensible, it removes the argument entirely, which is why plenty of workshops default to it on vehicles still under warranty.
What if my warranty claim is knocked back?
Ask for the decision and the reason in writing, then gather your service records and invoices. If the reason is simply that you used an independent workshop, or the fault has no real connection to what they are pointing at, you have grounds to push back. NSW Fair Trading runs a free dispute resolution service for problems with a licensed repairer or dealer, and that is the practical place to start. The ACCC does not resolve individual disputes, but it does take reports, and those reports shape what it investigates and acts on.
