Interesting, as there must be a lot of elderly people who have moved from diesels to hybrids to do their short journeys. There could be some attempted resurrections when the garden centres reopen (they're about to in Wales, although Boris, who has possibly never been to one, has said nothing about them in England).
My wife's sister had a similar problem with an Auris hybrid a few years ago: but that's a 12-registered car and I thought there had been a modification since then which had solved the problem, which was something about a slow discharge of the 12v 'starting battery' when the car was idle.
The 12v battery seems to be the weak link. Possibly whatever charges it in normal driving isn't as effective as the good old alternator?
(Edit - I was posting at the same time as Mcintosh, who has an answer that makes sense. Anyone know if all Hyundai and Kia hybrids use the same system?)

I’ve never had a problem with my 14 plate Auris so they must have fixed in production or a recall. That said, longest I’ve ever left it undriven is a week and I deactivate the keyless entry system if the car is not being used much, as at present.
Apologies, I was wrong about the IONiQ - it has a 12v Li ion battery which is charged by the hybrid system when driving and, crucially, a button you can press to charge the 12 V battery off the hybrid battery if the 12v is out of juice. See here for more info: https://www.caranddriver.com/news/a15341302/how-the-hyundai-ioniq-ditched-its-traditional-12v-lead-acid-starter-battery/
Sorry, shouldn’t rely on my faulty memory.

Amazing really, the brains dedication know how and millions of miles and hours of testing that must have gone into making their hybrids leaders (so far) in their field, yet Toyota engineers missed this now blindingly obvious fault, maybe the engineer's answer to this lack of enough typical use issue was overruled.

I can understand it might be a bit complicated on a car like the Auris which was originally petrol or diesel-engined, but the Prius has the same issue. I suspect it’s down to saving a few quid. It’s a bit like the lack of spare wheels nowadays - a small convenience for the manufacturer but potentially a large inconvenience for the owner.

I have a Lexus NX300h hybrid that was left for 3-4 weeks last year without being started and had no problems starting.
I would have thought (guessing here) while driving if the cars ICU detected the 12 volt battery needed charging the ICE would cut in until charged.

Yep. In fact, you don't even need the petrol engine running so long as there is sufficient charge in the hybrid battery. The petrol engine will cut in if the hybrid battery is running low.
The stop-start system on the Auris is meant to deactivate if the 12V battery gets low so I probably don't actually need to actually deactivate it manually, but I like to play it safe.

Hyundai manufacture lots of electrical products, fan heaters, toasters, kettles and batteries, so may well have more experience and foresight than other car makers.

Good point, I hadn't thought of that. According to the link I posted earlier the Kia Niro uses similar battery hardware so it may find its way to all Kia/Hyundai hybrids eventually. Certainly a useful feature to have.

Except Hyundai don't do consumer electronics anymore...they just licence out their brand name.

Exactly why they would take an interest n the design and quality control standards of the licensee, given the potential damage to their brand of dud products

It will be up to the licensee to ensure the standards are kept up...Hyundai would have no involvement - why would they as a car company it's not something that have knowledge in.
I expect the licensee won't make the items either as they will be farmed out to 3rd part companies. Many home electronic companies have 3rd parties make a lot or all of their products - even very large names like Sony and t***iba.

Among other courses the company sent me on I was Six-Sigma trained, this involved detailed work on Quality Control and process improvement, Our company had also adopted the continuous improvement methods as used by Toyota and other far Eastern manufacturers.
Any supplier or subcontractor to these companies is, as you say, responsible for the quality of what they manufacture but they are monitored very closely by the end user whose brand name is on the finished product.
Note also that Hyundai is not solely a car company, they also build the world's largest ships. (I believe their plant 5 is the largest car plant, their shipyard is also one of the world's biggest).

I suspect like good engineers, they took a rival's design, studied it, took note of all the significant defects in the design and made sure their version didn't have them. They appear to have done a similar job with their dual clutch transmissions - I don't recall any posts here or news stories about faulty units.
