Buying Tips for 2023 Genesis G70

  • ✓Check the operation of the infotainment system and digital dials; ensure the latest OTA updates have been applied.
  • ✓Inspect the large, intricate alloy wheels for curbing, as they are very prone to damage on narrow roads.
  • ✓Test the Advanced Driver Assistance Systems (ADAS), particularly the lane-keep assist, to ensure smooth operation.
  • ✓Verify the service history; the Genesis 5-year Care Plan requires strict adherence to maintain the warranty and concierge benefits.
  • ✓On diesel models, ensure the car has been used for longer journeys to prevent DPF (Diesel Particulate Filter) blockages.
  • ✓Listen for wind noise around the frameless doors (on Shooting Brake models) at motorway speeds.
