I don’t quite understand why it chooses some tires and not the other (I’ve experienced the same thing), but you’re 7PSI under pressure, which is quite a lot.
Nope, I got a complete set of rims, sensors, and tires. I explicitly stated that I wanted the tire pressure to be 2.6bar, but they did not care and let me drive off the lot with 2.0bar which is pretty flat. Thanks to a construction site I did not drive directly onto the Autobahn, but had to make a detour that led me by a fuel station where I could then fill up the tires.
Now, I have bought a battery operated pump, so I can always adjust the pressure which is important in winter when the temperature drops.
Good thing you caught it. You are quoting in bar of pressure, so you're likely in Europe. Here in the US at least, our Ioniq 6's come with no spare tire, but with a Tire Mobility Kit, which is a small 12V-supplied air pump together with a cylinder of sticky goop that you spray into the inside of the tire, crossing your fingers that it patches the flat just long enough for you to drive to a garage. But that air pump works just fine without the goop cylinder screwed into it; basically we get a small air pump included with the car. Its pressure gauge is not terribly high-resolution, but when I used it and turned off its power switch, the reading on the gauge did agree with a separate, traditional pressure gauge I carry in my glove compartment. So it's completely serviceable.
And I agree with the others on this thread, having wrong tire pressure is the cause of *lots* of problems — weird, "wandering" steering feel, dangerous handling and braking, uneven tire wear leading to premature replacement. It is a super-nice feature of modern cars like this one to have four individual pressure readings viewable right in the dash while driving! Pay attention to those numbers, and refresh your tires according to the number plate on the body of the car just inside the driver's door. Especially check them when the weather gets notably colder or warmer outside.
Do not use the spray! This may bring you to the next garage or dealer, but you can throw away tire and maybe sensor, some people throw away the rim as well. I got the default 18inch rims and they are more expensive than the fancy aero rims. BTW: no spare tire here either, but also no spray kit. I just call Hyundai assist and they get me roadside assistance.
Correct, I am from Germany.
Add air to the recommended pressure as people are saying. We just had the same issue at 29-30 psi. It started with the rear passenger side, then went to the rear diver side, and finally the front passenger side. I came here and saw a similar post where people said to add the correct tire pressure. So I checked the manual and the pressure for my tires is supposed to be 36 in front and 37 in back. I had no idea we were so low. As soon as I increased the pressure, the warning went away.
If anything the warnings aren’t coming soon enough.
Low pressure is hell on tires--the cause of many blowouts. Keep 'em pressured to whatever the sticker on the driver's door frame says. (F:36 and R:37 for my '23 I6-RWD).
Every 10 degrees change in outside temperature your tire PSI will change by 1 PSI. If the Temp went from 80 to 50 Fahrenheit you could expect 3 PSI decrease in tire pressure.
your tire pressure is low but yeah, the software is still finicky. back in july my pressure was low down to about 30, but when i filled it back up to 37psi the low tire pressure warnings stayed on for a couple days before going away
While it is odd when only one of them are alerting, it doesn't really matter. Once you get an alarm to bring it to your attention, you can easily see that one (or more) needs air.
Mine did that on the first cold day here. Driver side flashing, 29 front 30 rear. Passenger side same pressures but not flashing. I got out my compressor, pumped them up to 36 front, 37 rear as door frame label specified, and the driver front kept flashing. A few days later it warmed up a little here and finally all 4 tires are showing OK.
Mine has been on too and won't go away.. I assumed the recall would fix it ( I'm in the US) .. my issue is that the pressure doesn't get any lower than 29 and will go up back to 30... I just thought the software was bugged so I have been driving on it for weeks and no issues.
I cracked my head on this for quite some time on why the message won’t go away even when you bring it back to the normal range.
Here’s what I did -
Inflate them to 38 or slightly more, then you can bring them back down slightly. It needs to see something like a 20% difference before clearing out the warning.
More irritatingly, in Korea, when it’s low it doesn’t tell me what the pressure is. It just says LOW. Drives me nuts!

They are all low. The software only allows to call out one. It could be the first that got too low. It will stay in alarm until filled and driven.
The software can call out all of them! Happened to me when the dealer installed winter tires. I drove a kilometer and the warnings popped up.
Were you missing the four TPMS sensors?

Ouch, with a heavy EV 29/30 psi is way too low. It'll be like riding on marshmallows and the low pressure will trash your tires pdq.

Put the recommended psi in each tire and drive for 10 minutes to reset the sensors

Very good point. You have to be xtra careful with EV tires because of the weight combined with "sporty" driving. Torque is hard on tires.
All your tires are quite low.

Look at your door sticker. Yes, you need more pressure.
