Apple CarPlay keeps disconnecting (2021)

Wireless CarPlay on my 2021 Hyundai i30 keeps disconnecting at random intervals. In addition to that, it also disconnects at one specific location during my morning commute to work without fail every morning. To me they seem like two different issues, even though they share the same outcome.

The audio unit issuer for Hyundai, Seednav, has already released an update regarding this concern and I have installed it in my car. Unfortunately the issue still remains the same. Recent communications with Seednav have resulted in the blame being pointed towards apple. Is there a fix in the making for this issue?

The latest update from Apple (14.5) has given me enough proof to say that this is mostly an Apple issue rather than the manufacturers. Ever since my phone was updated to 14.5, the dropouts have reduced significantly. I managed to do a 3 hour journey today with maps and spotify running for the entire jorney without any issues.

Although it hasn't completely cured the problem, it seems like we are one step closer to the solution.

Apple is listening, they’re just not going to fix things in CarPlay that aren’t broken, and are going to make sure that they test changes they deliver as thoroughly as possible.


it all depends upon the actual issue being seen. For example if you see that your head end resets or becomes unresponsive, there’s nothing in the CarPlay protocol that a device can send to your head end that should be able to make it do that.

Hi Ditchy


did you mean to say the I30 never had a wireless option?......it was the wired that stopped working I think because of the 14.8 usb security update?......It is very frustrating because I figure CarPlay could be a reason for buying a particular model. Apple either never thought of the impact or the car manufacturers failed to upgrade in tandem.

Well...... they finally lifted my restrictions to posting on this site. I have good news and bad. Genesis Corporate finally got involved and fixed my issues with CarPlay continually dropping the program but since I can not say anything detrimental I can not tell you what they and Apple had to do to get it to work.

But with all of the issues I am reading on the internet with the IOS 15 I am reluctant to download it at this time.

You keep ignoring the several users who posted immediately before you did that their issues were solved by an update performed by their automaker.


Apple's fix does not mean the issue was theirs all along, just that, if the update fixed it for you, that your issue apparently was.


Note the release note mention does not mean iOS 15.0.2 fixed an issue for any user for whom the fix ended up being an update to their vehicle.

I recently rented cars.. BMW… VW… Hyundai and I have a KIA. The CarPlay disconnects with all of them. I just purchased a 13 MAX PRO and it is worse than my X.

That one seemed to disconnect twice (maybe three times) then be fine. This one… repeatedly.


I am using a wire for my car (2018 model) and the rentals have been 2021’s. Too bad… and to be fair, it’s pretty dangerous especially IF one is using navigation.

I had a 2020 Hyundai Sonata where Apple Car Play never disconnected. Then someone t-boned me, and I got a 2021 Sonata. The only reason I bought the same car again was BECAUSE of Apple Car Play. I deliver food, and it's critical that this feature works for me. All these disconnections are so dangerous when I'm driving. I agree with the person on this forum that said this is a lawsuit in the making. I'd really like some answers. I went to the Hyundai dealership, and they said there was nothing they could do. They said they weren't even aware of the problem, but I seriously doubt that. I recently upgraded my OS on my phone but nothing changed. So frustrating!

Thanks for your comments everyone… my CarPlay is “hardwire connected”. The 2019 changed that but mine is a 2018. I have arranged a get-together with the dealer’s service department. Both sales and service tell me they haven’t heard of this before (I know them well and believe them.) That said they’ve heard of it now and are eager to investigate. I’ll keep you all posted. Stay tuned… and BTW, there have been many comments here Re Hyundai. Mine is a KIA. Same car… just spelled and pronounced differently, so again, stay tuned. 😊

@micky_b2000 I'd live to contact you directly about this. I am going back and forth with Hyundai now. They claim technical support at Hyundai never heard of the problem which is a load of garbage. Do you have a case number I can refer to regarding this issue? Hyundai obviously clearly admitted a problem here. What was the make and model of the car you had? They refunded purchase price? I'm dying to know more.
