While it may be reassuring to some extent, it is also zero information about the real longevity of the car with a hidden buffer. Out of sight, out of mind is Hyundai's strategy. One has to wonder why. I think it is just marketing - a bit subtle perhaps to increase customer satisfaction and retention. But no questions have been answered about Hyundai's battery performance versus other makers.yeah this is reassuring for future long time holders of this car.

The above two comments are spot on. Another factor that affects battery degradation is extreme heat (and to a lesser extent cold). So trying to avoid battery temps of 40 Deg C or more or -20 Deg C or less (especially with high loads at those times, will help). The active battery temperature management system on the IONIQ is very effective under normal conditions and covers this off nicely.
Lastly, lithium batteries will degrade over time even without use, there is a sort of slow baseline degradation - it's just part of the chemistry. All the other factors discussed above just add to that. That said, evidence suggests that there is no reason your IONIQ battery shouldn't last 10 years or 200,000 km (or more) with only minor noticeable degradation losses.
I can't speak directly to the 38 kWh IONIQ, but I can tell you that the 28 kWh IONIQ classic battery, will take on ambient temps quit quickly when left alone - usually within an hour or two, unless you had it much (+/- 10 Deg C) warmer or cooler than ambient. If you will not be driving your vehicle and it will be left for an extended period in summer heat of about 30 Deg C, then I'd recommend trying to maintain a battery SoC of between 50% and 70%. Under those conditions, I do not believe that you will incur any additional degradation over if your were using the vehicle normally. From what I've read, the battery doesn't like temps over 40 Deg C, so 30 Deg C should be fine.Do you have any idea about how the battery is warming up if the car is in no use? We bought a New Ioniq and it will stay under the sun for about two months (we applied for gov subsidy and it takes a while).Summer is just starting with above 30 C degs (hopefully less Than 40 C degs). I appreciate any answer. Thanks.
Don't judge by the screen. As another user said, it was only an estimation based on recent driving. If you want to see the actual state of your battery, you have to bring it to an official car sevice. Most likely it is 100%. In the unlikely case if there is an issue, you still have the guarantee.I have a 2020 38kw Ioniq.
and have had a startling depreciation in my battery range. This is going by what the screen tells me. As I don't often charge my car to 100%. When I did yesterday I got rather a shock. When new at 100% my display said I could go 400km now it tells me 272km !!! the car is 6 months old and has done 21000km. I thought at first that the heater was on but it wasn't.
