Apple CarPlay keeps disconnecting (2021)

I have simular on my new 2021 G90. It always drops within 30 miles and then sometimes within 5 seconds after I plug it in. I have an iPhone 12. It also does same with wife's iPhone X and my other iPhone 7. I have tried ALL of the suggestions. Dealer says they have no fix.

Sadly, that’s the way auto makers tend to be.

They really aren’t used to dealing with user-supplied technology yet; their software schedules tend to run on months to years, though some automakers are getting better, especially the ones that can push updates over the air rather than via a service visit.

It’s happening with wireless CarPlay as well so it’s not just the cord that’s causing an issue. I had a 2016 Elantra with wired CarPlay and no issues. Now I have a 2021 Elantra with wireless CarPlay and have issues with it disconnecting randomly. I don’t have the option of using a USB cord anymore for CarPlay but I can tell you it’s not the cord that’s causing these disconnection issues because wireless Apple CarPlay is experiencing the same disconnection issues.

The common factor here is the Hyundai group, perhaps part of why they changed to NVIDIA as supplier for their in-car systems as of 2022.

Hyundai Motor Group Selects NVIDIA DRIVE Infotainment and AI Platform for All Future Hyundai, Kia and Genesis Models

Genesis Corp group sent me a download last week and so far it has been good. They are sending a tech on 19th to verify. It will still drop out after 30 minutes with one of my non Apple cords but one non Apple cord works at least for 40 minutes. Both Apple cords work

Are you tell us that you personally have performed a case study across all manufactures? I have not but I am reading is there are multiple car manufactures with different manufactures the head units. The one thing they all have in common is all who have complaints own Apple IPhones.

I did not say all, but I can tell you I have had zero issues with CarPlay on vehicles from Toyota, Jeep and Nissan.

Believe me, I tried to get this issue to reproduce but it worked perfectly every time.

Note that many car makers outsource their in-car infotainment systems to various manufacturers so they don't have to deal with them.

For example:

• Hyundai Motor Group Selects NVIDIA DRIVE Infotainment and AI Platform for All Future Hyundai, Kia and Genesis Models

It can also vary by geographic location:

• Yandex Becomes Official Supplier of Infotainment Systems for Renault, Nissan, and AVTOVAZ/LADA in Russia
• Renault-Nissan-Mitsubishi and Google join forces on Next-Generation infotainment

Have had the same issue ever since getting me Hyundai Venue 2021. Have had numerous updates on it. Changed out the entire headunit and no luck what so ever. Hyundai keeps saying it’s apple’s fault. They always tell me to wait for a new update (told me this 5 times now). Every Apple update never mentions fixes to Apple car play (Apple not listening). It had gotten to the point where Hyundai is offering me a refund on the car!!!! Absolutely fuming.

It started happening on the 13th (I was unaware of the 14.8 release or I would have tried to undo that update)...anyway I was hoping 15 would fix it but in the release notes it mentions that planned CarPlay updates were omitted from the release). I am not saying it is Apple's fault per se (because it may be quite possible that the car makers didnt make a change they should have) but if at least Apple would acknowledge the issue and then we would know who's responsibility it is to fix it.

I think I’ve figured it out. I was using a wired connection which stopped working on 13th September. I’ve recently discovered that 14.8 was installed on that date ( I have automatic updates set). This release was to do with security updates effecting usb connections. I have since bought a wireless adaptor and it works fine.

If you feel using your phone is dangerous, power it off and put it away until you reach your destination.

If required, automakers offer their own navigation systems if needed, and certainly rental agencies offer them.

That will provide maximum safety in your situation.

@de_mg Can you clarify. Are you saying you disabled bluetooth and just used Wifi?

Isn't Bluetooth needed for Phone Calls and Media Streaming (Spotify, Amazon Music)?

Wifi is used for the projection of the phone to the car screen.

What's why I don't understand the problem. Seems you need both subsystems. However the phone is 2ft from the infotainment system. So you should never be out of range of Bluetooth or Wifi. The flaw to me is the wifi not the bluetooth. There are too many things that can interfere with wifi and it that gets interrupted it drops the entire signal to the phone and all streaming stops and phone projection.

Well folks, I among others asked for help regarding this issue. I have a 2018 Cadenza (Kia) And just purchased a new iPhone… Which has all the bells and whistle’s. The only thing it didn’t do is connect to my car. There have been a couple of references on this thread regarding using an authentic Apple cable versus a store-bought. Well after months of being frustrated and screaming at my dashboard, I decided to take the advice. As of today, problem solved. Thanks to those who suggested the idea; if anything changes I’ll let you know! But I was driving around all day today and not once was there a disconnect. Thanks again to everyone.

The update probably is a coincidence as my 2021 Hyundai often works two week or more until it doesn’t. My dealer and I feel it is a Hyundai problem. All I know for sure is my 2018 and 2019 Santa Fe’s that had to be used with cable in USB port NEVER had this problem and still don’t.
