2024 Hyundai kona has similar problems with the 12v battery

I have two Bolts, but recognize the weakness of our 12 Volt batteries. Both of my bolts have a small "plug in" battery volt monitor, which I always keep an eye on. I'll replace the 12 volts at the drop of a hat when their capacities start showing degradation. I've already replaced each once.

Excellent useful video.

You saved me today brother. And you saved a meal I was bringing to a nursing mother in need and her 4 other children. Words cannot express my thanks adequately

Great review of the HUD system, can’t wait until I get my Ionic 5 sometime this December. Until then I’ll keep watching your channel for anymore nuggets of information about this amazing vehicle

You must always remember unless you are a magician, please do not turn your car into a pole.

Mines didn't come with that

That's exactly what I'm doing right now but was curious if there was any other easier way..idk using the tiny black little hair bands though, it's still easier and faster than filling 100 of these individually

Nice one. Just discovered your channel. I'm looking forward to my first Ioniq 5 in a couple of months time. Subscribed.

Thanks

Good

also you can unlock the port from AVN unit, the problem was in the set up in the AVN unit, its in unlock after finish charge.

It would be logical to drop the change threshold to 12.3V when the HV battery is below 20% and only stop charging the 12V when it's below 5%. I think if they allowed the 12V too charge permanently it could damage the high voltage battery which is about 300x more expensive to replace.

Mine died dyed today. My battery was at 23% when I parked it yesterday evening, and today it was all dead. Truly feels as the limit for when it stops charging the 12v should be a fair amount lower as it has very little effect on the main battery. In such a modern car I think you should be able to set that limit yourself even.

Hey lemon,where are you mate,we miss your videos!!!

Think the white looks stunning my preferred choice

Interesting that at "100%" you had 38.4 kWh capacity. That's more than I expected (36kWh). kzbin.info/www/bejne/nIDHhYeQaLKHeK8si=eyUnyTvdWLFL4BKa&t=168

you couldve used the cabin climate to test this...

Would be interesting to get another update if your family still own the Leaf?

Thank you!

Just realised dis video is 10 yr old

Thxxx. So mush broh

Scotland is beautiful

Thank you SO much for this video!! You saved me being stuck !

What is the input power it takes like 12v how many amps???

Hi James - just an update on things - over the past three months I've had one of the automatic air vents on the front of the IONIQ 5 replaced because it became intermittent and recently the Integrated Charge Control Unit which is a large liquid cooled box of electronics under the back seat replaced as the car stopped charging on AC. My car is a March 22 RWD so probably made late 2021. The dealer said they had done a few ICCUs. How has yours been?

Thank you so much for this video. It's happened to me twice now and not sure how I got around it before finding this fix

I'd read that there was a problem with the bluelink app accessing the car way too many times, the car would wake up then go back to sleep repeatedly causing the 12v battery drain

Super video

Tu peux parler ma belle ,pourquoi tu fais pas ettendre ta jolie voix? 😊

Waste of money! I bought three of these BM2 Battery Voltage Monitors so that I can check on my batteries of my stored/parked vehicles as well as my daily driver in my garage and driveway and I wanted to be able to check them while sitting in my home. The range is about 12 feet as I have to be at my front door to get a signal. This is typical of Bluetooth devices where they state 10 meters or 33 feet but in unobstructed view, but not under a hood shrouded in metal. If I need to be that close to a vehicle, I might as well pop the hood and take a DMM meter to the battery.

Okay! So avoid letting the car sit at less that 13%, or the 12V risks dying without being topped up from the HV battery. Good to know!

Was this video made before the brake light fix? The reason I ask, is a couple days ago on the hightway I saw another Ioniq 5 (probably an SEL) had two levels of brake light brightness, one low and other full on. I was wondering if the low brake light level was activated by regen and then the full brake light either by manual braking or the sensors sensing the car's deceleration? Thoughts?

hmm its works but its still jitterung movin around whitout my head moving and it has some jump flassh all the time fells like a bit of jitter and it jumps to the center evrytime for a split second Edit 1: i got the flashing away now its really woobly but i think its not the comfig its the cam resolution only 720 P HD 2MP i think i need one whit more pixels that its more accurate Edit 2: on movin my cam from top on monitor to under it so the cam dosnt need to look down oj me anymore it look from bootum up to my faceit works really finne it just woobbles 1 cm around

Thanks for taking the trouble to video your experiment. Very worthwhile! I'd expect that, if in Auto Mode there's a slow vehicle close ahead which requires your car to slow down, the lights would illuminate automatically. Mine is a 2024 Ioniq 5, which I really like.

I use the adaptive cruise, normal mode and auto regen all the time (well, most of the time). Works for me. Normal mode only uses RWD unless extra power/acceleration is required, auto regen applies level 3 regen when not in cruise mode and a full stop (without creep) is merely a matter of applying the left paddle for max regen retardation and it stays stationary once speed drops to zero (when the paddle can be released). Simple driving only affected when the steering wheel is well off centre. I don’t drive particularly fast but do occasionally enjoy the sport mode performance. 3.7m/kWh over the last 5k miles is OK for me - I don’t expect to achieve the economy of the RWD models on smaller wheels and quite a lot less available power.

this happened to me. 2 yrs and 72000 miles. hyundai said battery was fine as the large battery was powering it so it always showed 100 percent. the battery was bad and i bought a new battery for 250 at orielly and installed myself as they wont do electric cars . and i bought this jump starter also if it happens again. so if you get 12 volt battery mesage low, just get a new battery and stop going to dealer three times and playing games.

Excellent commentary and advice James….Thank you.

My Ionic 5 did this today at the most inconvenient time. My mileage was 210 miles to go. I never let my car go below 40 percent. Something else is causing this problem. Hyundai needs to fix this problem. It's to dangerous

This was perfect. It is just a hard car to figure out how big it is. I guess the width is huge. I could watch another video like this just comparing it to 400 more cars.

Ioniq 5 is also not charging 12V when charging cable from wallbox is connected (even if it is not charging)... Got 90% in 800V battery, connected to wallbox, and Got dead 12V 😂

This is absolutely fascinating and very informative. I wonder if there are some sort of awnings already being developed to fit on to the ioniq 5.

Many thanks and may all your chargers be super henceforth

Exactly what I was looking for. Thanks for making this!

Hello. Can these obds change the language?

Hey James,hope everything is ok,missed your videos lately,are you planning some more,i always enjoy watching them,informative and interesting

It's the same on ioniq 38... it's a known issue and the root cause is the short charging period (the spikes). A proper charging would be around 6h.

Apparently these's been a BMS update to fix this problem.

Flippin' beautiful car. Love mine, same color
