r/Ioniq9

We recently had a poor experience at Jim Ellis Hyundai in Atlanta. In the process of replacing our Ioniq 9’s floor harness (airbag light was on) the technician drained our 12V battery by leaving the door open for too long (never got an answer on how long).

Then, after we picked it up, we noticed that it couldn’t connect to Weather, Sports, navigation, or the mobile app.

We took it back and they had to replace the Data Connectivity Unit. I asked repeatedly if something happened to it because of the 12V battery drainage. Never got a straight answer from them.

Does anyone know if the Data Connectivity Unit is powered by the vehicle’s 12V battery? Google Gemini indicates yes but the sources it references don’t explicitly state that.

Thankfully everything is under warranty but it’s been frustrating to not get clear answers from the dealership/service center.

My electricity rates are different during weekdays and weekends. Is there a way to make different charging schedule per day like climate schedule? Thanks in advance

Anyone finding their 2nd row doors needing more force to close properly? I'm thinking that this needs to be broken in but a month in and i'ts still the same.

Numerous Reddit posts and even a couple of online EV mags have referenced an extended 15-year 290,000 km extension of the Ioniq warranty being applied retrospectively (and pro-actively) as pertains to affected ICCU units. Given that Hyundai and KIA don’t seem to have solved the ICCU problem (someone please correct me if I’m wrong) this warranty extension could be a deal-maker for us. We are strongly considering an EV9 but are scared silly by the ICCU problem, particularly the possibility that it makes the vehicle untenable after the basic 5-year warranty (or is it the 8 year?) runs out.
FWIW, the salesman at our local dealership in Ontario says he hasn’t heard anything from head office yet about an extended warranty for ICCU’s.
Has anyone seen official literature about this? Or are we all just bandying around the same rumours …

Anyone hear an occasional rattling noise from around the headliner? Since it’s intermittent, it has been hard to figure out exactly where it is coming from.

Looking for a Limited. Dealer says none around, only SEL. Is this the case everywhere?

I prefer to keep the recirculating on most of the time to avoid getting smells from the outside into the car. But it keeps randomly turning it off. Any idea how I can force it to stay on?

Updated the car last night. Wish I didn't. Update was for live maps and more but I use carplay so it doesn't matter much to me. Anyways, after the update, there is now an added step to the getting into the cars system. So now we get a drive safe warning/profile page, and a new start page with the weather. I just cant... Coming from Tesla's get in and go functions to this 30 second wait is so annoying. I don't need to select a profile every time. I know to be safe. I don't need to select start to get into carplay...

I wish the software would get out of the way and just let me use it and drive... First world problem I know.

So there is an old thread about this but it's almost a year old now and there has to be some good options/opinions now.

Hyundai doesn't seem to sell there own and just re-sells the Weathertech one. The weathertech one looks like the super cheap ones from Amazon but they want over $100CAD. And another $40 for the bag.

Any recommendations?

I am considering the 2026 Ioniq 9 with the NACS charge port, but I’m looking for clarification about where it can charge.

I read something about older Tesla charging stations (Gen 2 or less, I think?) only being able to work with Tesla’s.

Is this accurate? Could I pull an NACS Ioniq up to a Tesla station and it not charge?

Sorry, I am very new to EVs and am trying to understand

On older cars this is usually related to power steering fluid or pumps but has anyone heard the groaning noise when turning into or out of a parking spot at very low speeds? We are at 3k miles and the noise is inconsistent

There is a piece of plastic that is installed on the Ioniq 9's large display that looks like its a screen protector. I am not sure if it is removable (was it supposed to taken off by dealership?) -or- it is supposed to be there (part of the display). It does not have any remove tabs.

I am looking to put on an anti-glare screen to my display because I am tired of looking an my reflection in the display. It is difficult to see the turn signal image, etc. due to the reflection.

I purchased an anti-glare screen protector from Photodon [Hyundai Ioniq 9 2026 12.3-inch Infotainment / Instrument Display Screen Protector (SKU: 4152-01-MXT)(Film Type: MXT - Anti-Glare 50%)] and it seems to be larger than the plastic film that is there already.

Has anyone had success in finding an anti-glare screen that actually fits and works? It seems that the film needs to be curved to fit the shape of the screen. When you dry fit the Screen Protector from Photodon, it doesn't follow the shape of the display.

What is this film on the display? has anyone here remove it? Is it not supposed to be touched? Is it the protective film that is supposed to be removed by the dealer?

Lastly, and I am not really expecting an answer.... Why would Hyundai make the display that you need to operate the car so reflective that it becomes an distraction?

due to the screen's curvature, the Photodon screen doesn't fit

Anyone else have any CarPlay issues? Mine suddenly stopped working after a week and the fix so far is to restart my iPhone.

My new Ioniq 9 SEL is less than a month old, and I’m finally getting through all the documentation. Noticed that the “warranty” on the tires does not cover tread wear. I have Kumho 20” Crugen EV tires.

Defects in materials and workmanship are covered only up to the point I have 2/32 inch (1.6 mm) tread remaining (regardless of the mileage). No warranty for tread wear. Is this common? This is my first EV and I’m used to tread warranties (like 50,000 miles).
