Buying Tips for the Hyundai Ioniq (Hybrid/PHEV)

  • ✓Check for the "Battery Reset" button on 2019+ facelift models, which allows self-jump-starting from the hybrid battery
  • ✓Verify all recalls (Main Power Relay and Clutch Actuator) have been completed by a dealer
  • ✓Test the DCT for smoothness at low speeds; it should be more direct than a Prius CVT but can be jerky if cold
  • ✓Inspect the boot for dampness, which can affect the 12V battery or hybrid modules
