I took my Ioniq BV in for its 3 year 30000 mile checkup. I was surprised that there are is no traction battery checkup. The garage says that they only did what Hyundai tell them to do, and the test system can’t do any more unless there is a fault condition. Since the state of the battery is hidden from the owner because of the 4kWh headroom, I would expect to be told at the service. Has anyone got any more knowledge about this? There was much more information available on my previous Nissan Leaf.
