    I commute about 40 miles on freeways each way. When the car really gets FUBAR, it only happens on the freeway... I have to hope and pray there is a shoulder I can pull off on when it does happen!

    It seems like the more I narrow down my parameters on the Car Scanner app, the less this issue happens? It also seems to clear the low voltage error faster if I turn the car off and back on again. To me it seems more like a BMS issue more than an actual cell issue?

    I'm having the same problem or one similar. It happens at random intervals and and lasts between 10 and 30 seconds.

    Mine is a 2020 Kia Niro EV EX Premium, bought "Certified Pre-owned" which apparently means nothing of substance. It currently has 42k miles. I have replaced the 12v battery with no improvement.

    City Kia of Greater Orlando refuses to give me a loaner vehicle despite the safety concerns, and refuses to put that in writing, because they lack the spine to stand by their reckless decisions.

    I have a case open with Kia Corporate, but they deferred to the dealership and said to give them 7 days to reply.

    Any and all advice is appreciated.

    So after dealing with this for a while and trying to narrow down any direct causes for the faults, I finally gave in and took it to the dealer. Initially the dealer came back and said it needed a new HV battery but is now saying that KIA wants them to exchange a wiring harness. Harness is supposed to be installed today- has anyone else had a wiring harness actually be the cause of these issues?

    Any updates Merrick?

    Until very recently the issue had vanished. It happened again the other day in the rain. I'm glad to hear that others are getting work done about it, no dealer within 100 miles of me will even try to diagnose it. With no stored error codes and no official communication from Kia they pretend like there's nothing they can do.
