Expert EV, PHEV & Hybrid Battery Diagnostics & Repairs in Sunshine North

As Electric Vehicles (EV), Plug-in Hybrids (PHEV), and standard Hybrids (HEV) become the new standard on Melbourne’s roads, the need for highly specialized automotive care has never been greater. At JustFix Automotive, located at 120 Munro Ave, Sunshine North, we are fully equipped and certified to handle the complex technology powering your modern vehicle.

Unlike traditional petrol or diesel engines, EV and Hybrid vehicles rely on complex high-voltage battery systems and advanced thermal management. Whether your hybrid battery is losing charge rapidly, your EV is displaying a high-voltage warning light, or you simply need a specialized logbook service, we provide dealership-level expertise with our signature zero-surprise upfront pricing.

The Warning: High-Voltage Repairs by Unqualified Mechanics are Illegal

Electric and Hybrid vehicle batteries operate at massive electrical capacities—often ranging from 200 to over 800 volts. Because of the extreme danger of electrocution and electrical fires, it is illegal for a non-qualified, unaccredited mechanic to perform work on High-Voltage (HV) systems.

  • Warranty Void Risk: Taking your EV or Hybrid to an uncertified workshop will instantly void your manufacturer’s new car and battery warranties.

  • The JustFix Advantage: You do not have to pay inflated dealership prices to stay safe. JustFix Automotive is fully accredited and legally qualified to safely isolate, diagnose, and repair high-voltage battery systems. We strictly follow manufacturer protocols, ensuring your statutory and battery warranties remain 100% intact.

Our Comprehensive EV & Hybrid Battery Services

We utilize state-of-the-art diagnostic software tailored specifically for high-voltage architectures, allowing us to service a wide range of brands including Toyota, Tesla, Hyundai, Nissan, BYD, and Mitsubishi.

High-Voltage Battery Diagnostics (State of Health)

Is your EV range dropping, or is your Hybrid petrol engine running constantly? We perform deep-dive ECU scans to determine your battery’s exact State of Health (SOH). We monitor the voltage of individual battery cells in real-time to pinpoint the exact point of degradation without unnecessary guesswork.

EV & Hybrid Cooling System Maintenance

High-voltage batteries generate immense heat and rely on specialized, non-conductive coolants to prevent thermal runaway. We inspect battery cooling fans (which frequently clog with dust in vehicles like the Toyota Prius and RAV4 Hybrid) and perform specialized coolant flushes to ensure your battery operates at the optimal temperature.

Safely Isolated Mechanical & Suspension Repairs

EVs are much heavier than standard cars, leading to faster wear on suspension components and tires. We safely isolate the high-voltage system to perform routine mechanical maintenance, including shock absorber replacement, heavy-duty brake servicing, and steering alignment.

Frequently asked

Expert EV, PHEV & Hybrid Battery Diagnostics & Repairs in Sunshine North — common questions

Can any local mechanic service my Hybrid or EV?

No. Servicing the high-voltage systems of an EV or PHEV requires specific safety accreditations, insulated tooling, and specialized diagnostic software. It is illegal and highly dangerous for an unaccredited mechanic to work on these systems. JustFix Automotive is fully accredited and trained to handle high-voltage repairs safely.

Will independent EV servicing void my battery warranty?

No. Under Australian Consumer Law, as long as the workshop is legally accredited, uses the correct OEM-equivalent parts, and follows the manufacturer's logbook schedule, your warranty remains fully protected.

Why is my Hybrid car using more petrol than it used to?

If your Hybrid is relying more heavily on its internal combustion engine, it usually indicates that the high-voltage battery is degraded, the hybrid cooling fan is blocked, or the battery cells are out of balance. Bring it in for a State of Health (SOH) diagnostic scan so we can pinpoint the exact cause.

12 Months / 20,000 km Warranty

Every repair is backed in writing. You don’t pay upfront — settle your bill only once you’ve reviewed the completed work and you’re happy.
