This happened to me two days ago! I have noticed some quirks, or maybe normal things that I'm not yet familiar with as we just purchased our Niro EX mid July. When you start the car in ACC mode only, NO engine, NO hybrid start, just ACC (accessory) mode to run radio etc. you get the intermittent warning regarding starting the car to prevent battery discharge...... (12v lithium portion battery that is, not hybrid battery), well, when driving, if you pull into a parking space, turn off the car, but do NOT exit the vehicle, it's like it goes into this ACC mode because the battery warning starts showing up on the dash screen (same screen as backup cam), opening and closing the driver side door while remaining in the driver seat solves this. I suspect that actually exiting the vehicle fully turns it off, but when I got back in the vehicle, I pressed start, with foot on brake, and everything lit up, I was on an upcline so rolled back while shifted into reverse but noticed the steering wheel was tight, the car was NOT on in drive mode!! I don't think this is actually a software bug with the vehicle but a sequencing error on my part. So far everything has worked great 99% of the time......... I may just have to get out the manual and read the basics lol, like how to start/stop the vehicle and what various deviations may trigger various issues. Also, it would be a good idea for those of us experiencing this quirk to be sure to look just under the gas/hybrid battery gauge on the dash behind the steering wheel, the little car icon, if it is lit up, the car is read to drive, if it's not on the car is NOT correctly started and/or ready to drive.
