I love the EVs both these companies produce.
Test drove them etc.
However, what about the 12v battery issue and the level 2 charging issue?
I still see a lot of people on this site leasing and buying them.
Also realize leasing reduces the risk as you can turn it in after your lease is up.
But leasing won’t prevent getting stranded due to a dead EV that can happen with a roll of the dice even with a new 12v battery.
Even worse, I would like to do level 2 home charging but not if it overheats the lithium ion batteries.
If not for these issues, I probably would have purchased one of those 3 already.
Are these issues fact, fiction or somewhere in between?
Is there any way to mitigate or resolve them?
Painful.
What is the story with overheating on level 2? I thought they made a software update that throttled charging as it got hot like pretty much every other ev?

I would love to know the answer to that.
Have you checked Kia/Hyundai forums?
Good idea. Stand by.
Yeah, but that’s not really a fix. It’s a work around. Owners want Hyundai to actually fix it so that it can charge at max speeds to the end. PGE has super off peak rates from 12am to 6am, so at 11kw, you should get 66kw, but people are getting like 50kw or less, so the vehicle isn’t fully charged in that time.
The 12v issue is common among all EVs, but Hyundai only charges the 12v from the traction battery once per day, but only if the traction battery is at 20% or more. Additionally since the 12v batteries are not deep cycle batteries, continuous discharge shortens their life. Hyundai has had this problem since the Kona, but hasn’t been fixed in the Ioniq. Maybe it’s a feature.

So The 12v issue is common among all EVs where your not getting peak charge, but the other car makers dont have the draining battery stranding issue correct?
I went to the Hyundai and Kia forums at the EV Insider website.
Found it surprising there was not much talk about it.
Today is Saturday and I need to make a decision.
My good car is a gas guzzler and my old truck is a hummer H3 that needs a new gearbox seal (steering), can drive it but just wears out tires faster and unevenly cuz u cant do an alignment till fixed.
And of course brakes and rotors.
I think other EV makers are just better at addressing problems. If you’re conscious about how an EV works, you mitigate the problems that some owners are facing. For example, ice cars charge the 12v when the car is on, so when your 12v is reading 11.5 volts, start the engine and let it charge. With the Hyundai EV, there is no way to explicitly charge the 12v from the traction battery, so whenever I’m in the car, I make sure the car is turned on, and I never let it sit at 20% or under. I would rather pay $0.84/kw hour at peak time than my battery go bad so I’ll override the schedule to charge at peak.
Most of the talk is on Reddit these days and there are so many posts that they get pushed.
So just like a regular non EV car, you sit in your car with the key set to ACC, to listen to radio etc etc etc u drain the 12v.
So in an EV, if you dont want to drain the 12V just start it up t charge the 12v and never let it sit overnight at 20% or less without charging?
Sound easy
