Is the Renault Austral Reliable?

So far, the Renault Austral is showing promising build quality, especially in terms of its hybrid system and structural reliability. Most reported issues are related to early software, sensors and electronic glitches rather than major mechanical problems. Regular software updates and proper dealer servicing are key to avoiding most faults.

If buying used, it’s vital to inspect all the electronics, sensors and hybrid drive to make sure everything works as expected.

How to Avoid Costly Repairs

  • Keep the system software updated regularly
  • Use the car weekly to avoid battery drain
  • Wash sensors and camera lenses to avoid false alerts
  • Book annual dealer diagnostics
  • Get an independent inspection before buying used
