- ✓For the Niro EV, confirm the ICCU (Integrated Charging Control Unit) service campaign has been completed
- ✓Check for 12V battery health; if the car has the "12V Reset" button, use it sparingly as frequent use can damage the main battery cells
- ✓On HEV/PHEV models, test the 6-speed DCT for smooth shifting, especially when transitioning from electric to petrol power
- ✓Inspect the "Aero C-Pillar" (if fitted) for any rattles or loose trim at motorway speeds
