It seems a dead 12v battery is a common problem with this model. I had to be rescued by the AA with a dead battery. 2 days later it died again, despite being 2 yrs and only 14,000 miles old. Does anyone know of a way to access the battery in the boot/tailgate when it's dead? Surely Hyundai...

I've been reading on this forum about troubles with dead 12V batteries, and am thinking about getting a jump starter -- basically, a self-contained battery-operated product designed to safely start vehicles having sick 12V batteries. On Amazon this one is the only one of several I looked at...

I've read lots of posts about 12V batteries (this forum is how I learned of Battery Saver+) but didn't see anything on this specific issue. TLDR: My 2020 Ioniq Limited Plug-in eats 12v batteries for lunch. Hyundai acknowledged the issue with the battery management system (Battery Saver doesn't...

Up front, I know the 12v drain issue has too many threads started. however, this is new info which probably should not be buried. I do ask that you take all you specific 12V issues to one of the many existing threads. This thread should be only about the tech call upcoming. 1. This call is...

Hi all. The title says it all really. I recently had RAC out to replace the 12v battery which went dead, and since that I've had a message on the dash saying "Check Smart Cruise Control System" and another icon indicating that it is disabled. Authorised Hyundai dealer wants £95 for the...

Hi everyone. I am desperate with the Hyundai technical service and I am here to share with you the technical problem to see if it has happened to any of you. I have an IONIQ 38kWh Klass (lowest trim level in Spain) from October 2020. Since November 2021 I started to notice that the auxiliary...

Hi, My Ioniq has a dead 12 V battery. It's under warranty, and I've been chasing the dealer for over a month, but they're saying they can't get a replacement. I've been to the local auto electrician and had the roadside assistance people look at it, but they are both saying "it's not in our...

I decided from reading other's experiences that it won't hurt to charge the 12v battery manually. Can anyone see a potential issue with doing this? The reason I ask is maybe that's why my climate system is only blowing outside air. Perhaps the IONIQ 5 finicky "automated" system doesn't like...

I’m stuck at the parking lot right now. Ionic 5 can not be set to Drive mode. And also can not be switched off or locked. Called the service and it looks like 12v battery is depleted. Strange is I was charging car yesterday and used blue link app to check the progress. Is it possible that app...

Hi! yesterday I had a warning on Bluelink app about the 12V battery (red icon and warning text) Early in the morning I started the vehicle without problems and the warning is gone. Did you have a similar issue? Is it an app bug? IONIQ5 RWD 73,2kWh

Hello Every one I got this problem almost a month, I am using JuiceBox L2 charger at my home. I have to charge every day because I have to run around 120-150km daliy, but from Septermber x day, as usual unplug L2 charger and try to turn on a car for work, and car won't start all lights not on...

I’ve been having issues with my 12v battery draining. Since I bought the car, I often see the ‘aux battery saver has been used while parked’ message come up - maybe twice a week. That’s telling me that it gave the 12v battery a boost from the high voltage battery. Now that I’m driving less...
