What to Watch Out For

While these warranties offer great value, always check the fine print, such as:

• Required servicing intervals
• What’s excluded (e.g., wear-and-tear items)
• Warranty coverage on hybrid systems or EV batteries
• Conditions for transferability if you sell the car

Final Thoughts – Which Warranty Suits You Best?

• Want the most years with no fine print? Choose Kia, MG, or GWM/Haval.
• Planning to sell within 5 years? Most brands are transferable, but Toyota and Hyundai retain value best.
• Need a ute or 4WD with long coverage? Go for Mitsubishi Triton or GWM Cannon.
• Buying an EV or hybrid? Look closely at battery coverage—most offer 8 years.

In summary, warranty coverage in 2025 is more competitive than ever in Australia. Whether you're after value, peace of mind, or long-distance confidence, choosing a car with a top-notch warranty can protect your finances and make resale easier.
