Welcome, MDBridges! Sorry to hear you're having trouble with your Ioniq.

I could have SWORN I saw this before but I cannot for the life of me find it. I'm 99% I saw it on the forum here somewhere. I Google'd it and only came up with this post regarding a similar issue on a Sonata. Unfortunately there are no responses: No sound from the speakers - Hyundai Forums : Hyundai Forum

There are software updates as well as a recall of the media unit. It might be worth heading over to the dealership to have them check it out.

 

@MDBridges When in doubt, RTFM, which I did for the UK version. I wish I was more familiar with Hyundai, and I will be, but not yet as I don't have my Ioniq yet. Anyway, this seems to be a common issue across many Hyundai models.

There should be a small pinhole size reset button that you can use a ballpoint pen or a paper clip with just to the right of the Power/Volume button. Push that in, hold it for a few seconds just for good measure and try again. You will probably lose your radio presets and whatnot by doing that.

Another alternative is to pull the fuse for the multimedia unit and put it back in. While doing that, ensure the fuse is not blown and in good shape and replace if necessary.

Another bit in the manual says:
Select the [SETUP] button on the
audio system ➟ Select [System].
• Memory information: View My
Music memory usage.
• Language: Change the user language.
• Default: Reset the audio system.

Hope this helps!

 

Thanks for your pin-hole comment. Whilst I had the complete opposite problem to the person at the beginning of this thread (my radio would not turn off even after I left the car and locked it - the screen didn't work and I couldn't turn down the volume when I was driving), your pin-hole reset worked like a charm! Thank you!

 

Thanks Dave I'll try that reset too and look for the little hole, although I think I already did that in software but there are so many subsystems. The reset I did, wiped favourite radio stations, eco trip information too, so presumed I found the right "reset".

I've got it booked in on the 17th March, I like being able to give reproduction conditions and I don't have any at the moment other that it happens on starting the car, not initially but after having stopped, but that's it at the moment.

I did see a similar report on a different Hyundai and have seen faulty head units on the Ioniq crop up.- Knowing my luck it is probably a loose connection somewhere! I'll keep this thread alive with results of the 17th so if anyone else has this issue they'll have a starting point.

 

Definitely try the pin hole first. So many others on the internet have indicated this has been the fix for them (at least on other models).

 

On the steering wheel there is a volume switch on left hand. Pressing down this switch mutes your entire audio. Has this been pressed accidentally? Press it again to restore audio.

 

I often do that when taking a sharp turn or reversing so it's a possibility

 

Did you solve the problem? I am asking because... I got the same problem today!..

 

Update: when I started the car this morning, audio could be heard again. I didn't reset or change anything.
There is be a possibility that yesterday's problem was heat-related, because when I started the car, temperature was 37 degrees Celsius in the shade, and the car had been under the sun for several hours.I drove for 5 km without audio, then stopped the car and hybrid system, then started it again but still: no audio for the remainder of the 30 km trip. No radio sound, no media, whatever the volume level. And it was not in "mute" position either.
Audio came back this morning, as mysteriously ads it had gone.

 

As I can recall his media unit was replaced.

 

Just had the same problem on my UK Hybrid Premium SE.

I was reluctant to use the pinhole reset, as I did not want to lose my radio presets or perhaps risk deleting my stored phone numbers.

There was no sound from the radio, incoming phone calls, navigation or even the musical serenade when powering down/up the car.

I tried powering down the car and powering it up again, twice. Still no sound.

Left the car overnight.

Next morning, started the car again, and the audio was back, and normal on all systems.

Does anyone know what causes the problem and if there is a fix for it?

 

It may indeed be heat related.

My audio died when the outside temperature was 32C, and the car had been parked in the sun all day.

 

As I mentioned yesterday my mirrors didn't automatically unfold when I came near the car . They started working again last night. They have been working perfectly ever since.


Wonder if it is a temperature issue. My car had been parked under the sun for a long time when it happened.

 

I find that if I go to the boot first and open it to put in shopping etc, the mirrors never unfold when I go the door. They unfold only when I push the door handle button. They have always unfolded when I go the the door first.

 

I've had the 'no sound' problem, as described, at a rate of about once per month for the last 6 months. It's not a heat issue, it can happen first thing in the morning. Always from start-up, it has never stopped working mid-trip. Note that it's all audio ... indicators, lane warning, etc. Leaving it a few hours sorts it out, but a simple restart doesn't help.

PS I haven't bothered with Fuelly for a while - but now at 61.4 mpg

 

Your description perfectly matches my experience with my 2020 Ioniq Hybrid. Came here looking for hints. Will try a few that others have suggested.

 

I would get the car booked in for investigation, at least to get it logged so they are aware of the issues

the ideal would be to be able to take it in and demo the fault to service tech(or take a video on your phone), but normally these sort of intermittent faults always occur when the service department is shut (bit like a toothache, it goes once you book appointment)

how long you had the car and what mileage you up to to get 61mpg?

 

Just under 10,000 ... so I'll get them to look at it when they do the service. I think the media unit is on recall if I remember rightly. Really hoping the service is 10k not 8k!
I drive in sports mode a lot, every time I pull away. So I'm very happy with the mpg.

 

After 10k, I still love the car - wish my second one was an Ioniq too! The only annoyance really is that recirc turns off after a few mins (15?) so if you're in traffic you'll get a cabin full of diesel eventually. No warning. Now I'm tuned to turn it off/on every few mins, so the timer never runs out.

 

And there's still the weird thing about the hatch unlock button. It might just be me, but I don't see the point. On VW the hatch opens temporarily, but Ioniq just unlocks. Just as it does if you unlock the whole car. So I tend to just unlock the whole car.

 

I would give them a bit of warning prior to service to allow time to get a replacement nav unit in

 

I spotted my first other Ioniq in the wild this weekend. We waved! Brotherhood of Ioniq. Not bad for 10,000 miles.

 

This happened to me today for the first time. I shut my car off at a red light and restarted it, and the issue didn't fix itself. I'm getting back in my car in a bit to see if having the car off for a few hours might've solved the issue. This is super bizzare.

 

It happened on my two IONIQ Electric from time to time. Sometimes it's enough to leave a car for the night and the sound will work next morning, sometimes it does not help. Using "reset" pin definitely does not help, but I know for sure a recovery method which always works for me. In the fuse box, there is "AMP" fuse, just pull it out and plug it in again. This will power-cycle the audio amplifier which I suppose is a real reason for this problem.

It seems that this is quite common problem.

 

Just fixed mine by pulling the AMP fuse ss above.... thanks.
I was getting the start up bings but no radio mdeia or nav sounds...

Hi, I'm an IONIQ EV (AE.3) owner from Australia. My cars sound just stopped working this morning also. I've tried power cycling, i've tried the pin reset, i've tried all the audio control settings (in the menu, on the steering wheel, on the console), still no audio. Will let the car sit a few hours and try again when I go home from work. Does anyone know of a specific recall / recall number I can refer to when I take mine into the dealer?

 

There is nothing on the ACCC site about Hyundai recalls for the MY20 Ioniqs. Only 2019 version wheel nut issue.

Search consumer product recalls

Search for the recall of a specific consumer product or types of products. There are steps suppliers should follow to run a recall and actions consumers should take when a product is recalled.

I had the same problem yesterday with the 2020 model. Audio didn't work at all. I went to the dealership, turned the car off, came back with some guy few minutes later and after turning the car on again it suddenly started to work 🤨

 

Hi All, I have an AE3 2020 Electric Ioniq Elite and had had this same problem for the last 8 months now. about once a month the audio and nav sound stop working for around half a day. this has happened sometimes in the morning and sometimes in the afternoon so is definately not heat related, also has happened even if the car is not on charge. You can reset the system with the small button on the left of the screen as many times as you want and there will be no difference, and also the reset on screen menu makes no difference. But leave the car for around 4hr and then next time you drive it, all is working again fine for another 4 to 6 weeks. I have had one software update from Hyundai back in March 2020 but this still happens, I will get another software update from Hyundai as they are aware of the problem (local branch had never heard of the issue until it finally happend after work one day so I drove it to the dealership to show them) but they were not sure what is wrong except another software update might help.
So I gather there are still no answers for this?

 

leave the car for around 4hr

I don't know your car, but for me, I only have to leave the car, lock it, wait for one minute outside and next time I open the door and start the engine it works again. I haven't tried the mentioned method with pulling out the audio fuse, but I will eventually.
