If you’re considering an auto electric tailgate upgrade for your vehicle, one of the most common concerns is:
👉 “Will this void my car warranty?”
It’s a fair question—and one that often gets confusing answers.
Let’s break it down clearly for Australian drivers so you can make the right decision with confidence.
The Short Answer
No — installing an electric tailgate will NOT automatically void your car warranty in Australia.
But there are some important conditions you need to understand.
What Australian Law Actually Says
Under the Australian Consumer Law (ACL), manufacturers and dealerships cannot void your entire vehicle warranty simply because you install an aftermarket accessory.
This applies to upgrades like:
- Electric tailgates
- Towbars
- Bull bars
- Infotainment systems
In other words, adding an accessory does not cancel your warranty outright.
When a Warranty Claim Can Be Rejected
Here’s the key point most people miss:
A manufacturer can deny a specific warranty claim if they can prove:
👉 The aftermarket modification caused the issue
Example scenarios:
- If an electric tailgate is poorly installed and damages your vehicle’s wiring → that repair may not be covered
- If your engine or gearbox fails → your warranty remains valid (because it’s unrelated)
So your warranty is not “void”—it’s just limited where the modification is directly responsible.
How This Applies to Electric Tailgate Upgrades
For an auto electric tailgate retrofit, here’s what you can expect:
✅ Still Covered Under Warranty
- Engine and transmission
- Suspension and steering
- Air conditioning system
- Most factory electronics unrelated to the tailgate
⚠️ Potentially Not Covered
- Tailgate motor or struts (aftermarket parts)
- Electrical issues caused by the installation
- Any damage linked directly to the upgrade
The Real Risk: Poor Installation
In reality, most warranty problems don’t come from the product—they come from how it’s installed.
Common issues from low-quality installations:
- Incorrect wiring connections
- Cutting into factory harnesses
- Water leaks from poor sealing
- Misaligned tailgate operation
This is usually when dealerships push back on warranty claims.
How to Protect Your Warranty
If you want peace of mind, follow these best practices:
1. Choose a Vehicle-Specific Kit
Avoid universal kits. Use systems designed specifically for your car model.
2. Get Professional Installation
Experienced installers like Auto Retrofit ensure proper integration and reduce risk.
3. Keep All Documentation
Save your:
- Installation invoice
- Product details
- Installer warranty
4. Use Plug-and-Play Systems Where Possible
These minimise interference with factory wiring.
What Dealerships Don’t Always Tell You
Some dealerships may suggest that any modification will void your warranty—but legally, that’s not accurate.
They must:
- Prove the modification caused the issue
- Assess claims on a case-by-case basis
If unsure, ask the dealership to put their statement in writing.
Is an Electric Tailgate Upgrade Worth It?
For most Australian drivers, the answer is yes—when done properly.
This upgrade offers:
- Hands-free convenience
- Improved safety features
- Reduced physical effort
- A more premium driving experience
It’s especially popular in cities like Melbourne, Sydney, Brisbane, and Perth, where daily convenience makes a real difference.
Final Verdict
✔ An electric tailgate upgrade will NOT void your entire warranty
✔ Specific issues may not be covered if caused by the upgrade
✔ Quality installation is the most important factor
Conclusion
Retrofitting an electric tailgate is a smart and practical upgrade—but like any modification, it needs to be done right.
With the right product and professional installation, you can enjoy the benefits without compromising your warranty.
