Battery Recall 196 - Dead after recharging

Thanks for all information here, is difficult to find information my own language, and our local Hyundai dealer or service centers. I feel that many electric car systems are new and not knowing... I have a 12V battery problem before Christmas and wait four weeks Hyundai brand battery and when replacing the 12V battery, next trip happens same again and now wait for high voltage battery the first week, hope that the battery coming soon and I get my Kona witch stop working about 300 km from my home. Both times same error message by a fast-charging station. Check vehicle electric system and gear not connect. Both times Kona transport towing track to a service place.

 

Yes, it is always "why me"?
My car was ready last Friday, after 3 months , charged up, ready to go. But I loaned it to them car for over the weekend use. Call me crazy but I wanted to make sure she will charge up again, not falter in my garage as apparently happened to some on this board. The sales manager put on it about 40 km. I picked up my car last night, it was charged to 100% and had a guesstimated range of 448 km. Mind you it was -10C.
While I was separated from my Kona I had a Sonata, a loaded Tuscon and a fully loaded gasoline Kona as loaners. For me, neither was as enjoyable as the Kona EV. Boy I love to drive my car! We did a 115km tour around on nice country roads today to celebrate.

The service manager told me that beside the new battery they also installed three recalls/updates. They did not get all the paperwork from Hyundai so I don't know the details. I am supposed to get a copy, describing all the work done, once all completed.

I did notice some changes on the user interface. So far I noticed the following changes/new stuff:
1. 'Energy Flow' image which reminded me to my Prius and
2. The 'Auto Regeneration' notice below the ODO. This is a strange one. Since I like one pedal driving, I set all three drive modes to Level 3 Regen. Still this Auto Regeneration message shows up. Not particularly upsetting but I would like to know Auto Regeneration really is. So far I did not figure out how to show Regen 3.
3. I was looking for the much discussed 'Winter Mode' setting, but so far I could not find it. I think they got rid of it. If so, it was smart move!

 

I know I can manipulate some of the display elements with the steering wheel buttons. The "Energy Flow" image is an add-on to the exiting list you can pick to display. I am rather interested to see the power used kWh/100km.
I sent a note to the service manager asking for ROM/battery info info. As far as I know the bad battery is still at the dealer. The label on new battery now may be hidden. I was told previously that they had to remove the battery to get to that label. I don't know. In any case I will send you a copy of the paperwork when I get it.

I never use the 'granny charger'. It is in the car for extreme emergencies. I do have a Clipper Creek L2 charger on the top of it with a NEMA 14-50 plug. They both fit nicely in the little bag supplied for the granny charger.
I will check if granny has a rubber sock tomorrow. Why?

 

Auto-Regeneration seems to me only when you brake by holding down the left paddle. Above approx. 87% charge, a warning signal will sound and a message that the battery is too full for recuperation. I have the impression that the most enjoyable ride is when you turn off the recuperation (you are sailing) and if you need to brake, hold the left paddle shorter or longer. You can easily feel the moment when the engine braking becomes too hard and release the pressure. I still have the Winter Mode option, but I have not noticed that it works at all, even despite the negative temperatures (° C), maybe the updates are removing it.

 

When you set the regen level to 0 in Kona, it still has some regen: you're not fully sailing.
As I was told, in Ioniq 28 kWh, Level 0 really was/is no regen at all, that is pure sailing like in Neutral.
I would like to do the same in my Kona

 

Well, you are probably right. It is enough to take a look at the screen that settles energy consumption, which even when sailing shows a low energy recovery of <2kW. It's a bit weak and unreasonable.

 

I don't have access to the car right now, so I won't give you the verbatim wording of the message, but the thing is that when braking with the left paddle, it squeaks and shows a warning that auto-recuperation is not working due to the battery charge level being too high. But of course the recuperation works normally, which you can see on the central screen in the window showing where our hardly loaded kilowatts are going, and the car slows down as always. The warning appears each time you brake the paddle until the battery charge level drops below approx. 85-87%. It surprised me a bit at first, but it didn't bother me that much, so I stopped paying attention. Next time I will try to take a picture, or look at the manual, maybe there will be something there.

 

First I never use the paddle. I LOVE "one pedal driving". It is the most energy efficient way to drive an electric car. (Even if Volkswagen disagrees.) We got used to drive without the clutch pedal, no we should get use to drop, well not quite, the break pedal.
On the new software you can't set Level 0 Regen on Kona. There are options 1; 2 or 3 only. See the image below. The other pictures show the 'Eco Potential' at various regen settings.
At regen = 0 the Eco Potential would be 0. Nil, Nada.
Regen is an EV thing, it has environmental and $$ (saves on breaks!) benefits. Get used to it.

 

This is nuts! This car, all cars today, are full of computers. They should automatically set the regen rate when the battery is "too full". Now that I think about it! Maybe they fixed this in the new software and that is the reason I for the 'Automatic' regen display under my ODO. Now I recall when I picked up the car on Monday, Feb 1, it was charged to 100%. I stopped on the way home and set the regen mode to 3 and still noticed the Auto regen display. which was unexpected. BUT regen still worked. I did pretty good with one pedal driving all the way home. Go figure.

 

First my granny charger has a rubber underwear.
Second, are you ready? My dealer called me today that I should stop driving the car immediately because the battery should have been mounted with new mounting bolts. Hyundai Canada told the dealer that the battery mounting bolts are "one time use" bolts. They took the car back, gave me an other loaner. Of course they don't not have these bolts and their ETA is about a week.
I was promised that they will try to read the info you are interested in.

 

I am, grounded once more! Please read my notes below. More details there. Here is the label info from my old HV battery.

 

I noted my experience with the 'Auto Regeneration' display after software upgrade. See items #51&52 above. On the picture my battery was at ~80%. The temp was ~-3C. Surely there is some sort of solution to apply regen when needed and protect the battery from overcharging by somehow 'burning off' the excess power. Is this the function of the 'Auto Regeneration' in the new software? Would this theory make sense? It would also eliminate the need for the confusing messages.

 

Auto Regen gets shut off with a software update. Happened every time I took it in. But simple to turn on again on the steering wheel dash settings. Then the Auto Regeneration display will turn blue when you come up behind another car, and will slow the car with regen if you get too close.

This Auto Regen is not to be confused with the paddles or the regen settings for each Drive mode which are set up on the big HU screen on the right. There I set my ECO mode to regen level 3. The amount of regen applied when slowing/braking by paddle, by brakes, or by just letting off on the throttle is displayed on the bottom left side of the dash. Since I have my ECO regen set to 3, I will see 3 bars light up when I let off the throttle.

My apologies if this is not news to you. But I did not quite understand your discussion about auto regen.

 

No need to apologize, we are all learning here. Before I left my car at the dealer in October I never noticed 'Auto Regen' on my display. God, that was three months ago. So I admit it is possible that it was there. From some reason it just struck me after I regained ownership of my car - if only for a couple of days
However, after the upgrade I noticed that, as you said, the Auto Regen message did turn green from time to time. It seemed to turn green when I was letting off the throttle to slow down. Which intuitively made sense to me. I wish I could experiment but I lost may car again, waiting for screws!

Not sure where I lost you with my discussion. Let me know.

 

I asked if they could possibly read the label from the new battery. If it is indeed covered now, we are out of luck.
