Very difficult to say as you give zero information about what type of driver you are. I'm a leisurely driver making rare motorway journeys, usually urban driving of sufficient distance to ensure the engine fully heats up, don't use Sport mode etc. My figures are a tad better than yours. Post a photo...

I don’t know if you've tried to use the webpage for which I provided a link, but it leads on to https://update.kia.com/EU/E1/updateNoticeView/624. Look at Notifications, read the latest May22 which seems to indicate that a maps update is available for most Niros.

Go to https://www.kia.com/uk/owners/navigatio ... re-update/ and follow the instructions. It's a complex process involving a PC and high capacity USB memory stick. I've not tried it myself yet, insofar as my car is recent and was updated when new. Good luck, let us all know how you get on.

I haven't experienced it, I don’t know if its simple to fix, but it's almost certainly covered by warranty.

Move the mirrors switch to either left or right and leave it there. The mirrors will now tilt when reversing.

It's in the User Settings "Other features" on the small screen above the steering wheel. You will have to scroll the options using the controls on the steering wheel. Page 5-50 in the manual.

The 12v battery is kept charged by the main HV battery if battery saver+ is enabled. So I can't see why you would want to bother, unless you rarely use the car and only charge it very infrequently. As to whether trickle charging would cause problems to the electronics, I don't know. Nor, I suspect, ...
