There have been several threads discussing this, with some seeing days pass.

The OTA updates on older models were limited to the infotainment and nav systems, so probably less data to download. These updates continued when the car was off...

ccNC models can update more of the modules in the system, so it can take longer, and might only download while the car is in range of an internet connection (Verizon in the US), and while the car is on.

It might speed up if you leave the car parked outside (better signal) and running for a long period. Just speculating, but perhaps the 2 days is limited operating time and delaying while the car is off?

There could be enough ccNC model owners on the forum who have experienced updates, so maybe they can shed more light?

 

Hm interesting. I've got a brand spanking new 2025 model. I'll try turning it on (which I can do remotely!) and see what happens.

 

what is ccNC model ?

 

Infotainment OS. Older models used the 5W operating system, 2025 have the newer ccNC system.

 

Pages 257-259 in the 2025 Ioniq 5 owner manual list all the do-or-die steps for OTA software updates...who knew..?..

 

Well I got an alert yesterday that the download was complete. Now I have to wait for it to be installed, we'll see if that happened overnight. I'm a bit surprised that there isn't an option to connect to the car to external WiFi for things like this - our Bolt has it as an option (oh and walk away door lock by default too!)

 

There are a lot of great features on the Bolt. Kind of amazing in such a budget econobox!

But Bolt OTA updates are infotainment only, and extremely rare. My Bolt went 7 years with a single OTA update to the infotainment system...and it basically just removed the ability to watch videos on the Car Play/AA screens when parked.

 

No joy still waiting for the install

 

Mine has said "Update in Progress" since I picked it up from the dealer five days ago. Sigh.

 

Once downloaded, my update took 10 minutes to install.

 

I wish I lived in your world it’s been days since it downloaded for me. The screen just says preparing to install.

 

Took days for my 2025 Ioniq 6 to download this. but finally did and I got this version:

 

I can't find it on the update website, but the car gives me a link to:
