Buying Tips for the Hyundai Ioniq 5

  • CRITICAL: Verify Recall 272 (ICCU) has been performed; this includes a software update and potential ICCU/fuse replacement.
  • Check for the "Stop vehicle and check power supply" warning history, as this indicates a near-total 12V depletion.
  • Listen for a "clunk" or "knock" through the steering wheel at low speeds or when parking.
  • Ask if third-party apps (e.g., Optiwatt) have been used, as these can trigger 12V drain by repeatedly waking the car.
