I think that the engine starts when you first start out so that it gets up to temperature. At least it seems that way from my observations.

My flat 12v battery problem seems to have gone away (touch wood). I have now done 14500 miles, so 3500 since the last flat battery. Don't think the dealer did anything to cure the problem, just disconnected the battery, presumably to measure the current. (The radio and satnav had both reset - that's how I know.)
The dealer never got back with any news from KIA technical - but then I didn't expect much.

Nothing to report. No more incidents. 15000 miles now, and I've had the car 11 months.
No word from the dealer, but I haven't been back to them so I guess they've just forgotten about it.

This has happened to me FOUR times in the last month. They have now concluded that it was (like two other cases on the forum) due to a faulty fuel pump not switching off. The amount of time and trouble it has taken to get this far is ridiculous. I hope they have finally found and corrected the correct problem??!!

The first two occasions were on the same day. KIA assist (RAC) concluded it was due to a dead cell in the battery. Took it into the KIA dealers who kept it for 24 hours and insisted the battery was fine (suggestions I must have failed to close the boot!!) or similar!!)

The third occasion was when we were away for a few days. This time KIA assist (RAC) concluded the boot light hadn't been switching off. We had already noticed that the boot needed a 'firm closure so were not convinced.

Booked car in for a check a week after our return and it failed again that morning at home. Thankfully the dealership sent out a couple of chaps who plugged in a terminal and confirmed the battery was 'faulty/dead'. They reported back to the dealership. I was then told I had to call out KIA assist (RAC) and get my car into the dealership. They agreed there was a battery fault but there was then a wait of 24 hours for a new one. In the meantime their checks indicated the faulty fuel pump - as I had mentioned to them the previous day courtesy of reading this forum.

So they have changed the fuel pump as that is what their checks show is broken. The new battery has been kept in stock.

If it happens again................................................................

One RAC man indicated that he had been called out to a NIro which had a flat battery where the boot had been left open whilst it was being packed to move house. Why doesn't the light switch off after a period?.

This has happened to me twice now. I've only had the car 2 months and done 2500 miles. First time called RAC out and he couldn't find a problem and jump started car and all was fine until today. I've left the car for 2 days and not used it and it's flat again. The dealer checked it over last month and didn't find anything so am going to jump it and take it back today. I will point out the fuel pump fault I've read about here and see what happens. This is totally unexceptible from a brand new car and am considering giving it back and cancelling my PCP deal....if I can. 🙄

there is issues arising from rear door lock catches causing a battery drain and your dealer should carry out a dark current check and follow the workshop manual to confirm the drain. as for the 12v battery charging that is the function of the DC DC converter As soon as the vehicle is EV ready the battery is being charged no need for the engine to be running
