Apple CarPlay keeps disconnecting (2021)

You have to understand customer relationships and allowing the customer to choose something else even though it may not fix the issue. In my instance it was an apple and Genesis fix but I will not post what the fix was because you will not post because it was, in part, an Apple issue.

Omg thank you sooooo much VBZ01!!! This has worked! For the venue it is the number 1 variant not the 4th!

i was gonna get my car refunded this week! So glad you found this! Saved me thousands of dollars

life safer.

HYUNDAI STOP LYING TO YOUR CUSTOMERS

Curious where you got the engineering codes and if they are the same on all makes/models...

I have a different model and live in a different country, but will 100% be showing your video to the service manager and requesting this "fix" be applied. It's certainly not ideal. My preference is wireless as it allows me to use a speed charger while driving. In the past, I found that normal charge speeds while using maps and streaming music still drains the battery of the phone even when it's plugged in (just slower).

However these constant disconnections are super annoying. So I'd trade a fix for that for battery charging issues any day.

I likely won't hear back from them for a few weeks, but I'll update this forum when I learn if a similar fix works in US on the 2022 Hyundai Palisades.

Absolutely awesome! Thank you so much for sharing this video! I have a 2021 Kona electric and the fix worked like a charm!

I just had to re-configure language and radio favorites. But that was done in seconds!

I’ve had trouble with Apple CarPlay for over a year. After much frustration and installing, uninstalling. I finally read that using a non certified Apple USB would cause issues.

I purchased a certified Apple charging cable…No problem since!

Hyundai has a fix for Apple Car Play. They installed the new update for me on Tuesday at Suttons Sydney and it hasn’t dropped out once since. Took about an hour or so. They said they were still testing it and I was a guinea pig so not sure if it’s being rolled out actively. But it’s good news!

FINALLY SOLVED*

TLDR VERSION: The USB port in my 2021 Jeep Wrangler console (under the armrest) was not *compatible* with my iPhone 13 Pro. I had to use the USB-C port on the dash to prevent the constant freezing/disconnecting of Carplay.

LONG VERSION:

My iPhone 7+ and my wife's SE never had an issue. We literally drove across the country without a disconnection. After we upgraded to new phones (13 Pro and 13 mini) the problems began. When using the USB cable to use CarPlay, Maps would lock up/freeze and the phones would disconnect. I tried every imaginable solution out there (audio/night settings, different cable, reset the phone, factory reset the phone, reset the head unit, went to the dealership to update UConnect to the newest version and on and on). I wasted DAYS on this issue. Finally, I unplugged from the USB port in the console and used the USB-C port on the dash. One hour in - and no disconnections. Before it disconnected every minute or so. So it seems fixed. I'd like to blame Apple (especially being they closed my ticket without solving anything) - but it's probably a combination of UConnect and Apple. Now, I vastly prefer to use the USB port in the console as the ports on the dash are poorly implemented, but at least I can use GPS now without disconnections.

*Now, dear billion-dollar companies, fix yer bugs so I can use the car as designed.

My 2021 Hyundai disconnects with apple car play and we tried to fix different ways but time will tell if this works. I am skeptical as they advised Apple does not support the 2021Ionic but do support the 2017-2020 Ionic. My granddaughter has a 2021 Hyundai with a different model that Apple does support and she has no connection issues with apple car play.

Hi there,

I have e very similar experience with disconnecting Apple Car Play BUT for me it is happening while my iPhone is connected via USB cable and on vw touran. Nothing seams to work and loosing connection is super random.

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.

I bought a Pioneer DMH-Z6350BT which has wireless Apple CarPlay. I have the same issue with CarPlay dropping out at exactly the same place every time, with both my phone and my wife’s phone. CarPlay doesn’t drop out if connected via usb. It also works if I play audio when the phone is connected via Bluetooth, but then no CarPlay. As CarPlay connects using wifi I suspect it’s a wifi issue.

A bit of an update from me. When I first bought the Palisades (2022), wireless carplay was a complete mess. It dropped constantly. I complained to service with no results. They point fingers at the device, the service, etc etc. There is a great video here of someone using engineering mode to force the car to work "Wired".

However, since we bought the car, we upgraded our phones (iPhone Xr to iPhone 13) and changed service provides from AT&T to T-Mobile. Since this change, connectivity has VASTLY improved. I rarely, if ever drop signal from the device to the car. I believe part of the problem is related to the strength of signal and the fact that we are now using 5G.

From a technical perspective, I don't understand why this change of provider/device matters at all. Regardless of the cellular signal coming to the device itself, the device should remain connected to the car's wifi and bluetooth subsystems. I could 100% understand if streaming music stopped due to no internet signal, but why would the device lose connectivity to the infotainment system itself?

I am still bothering the service department as I know they are aware of this and they should be held accountable.

There is one specific issue that is the most troubling and that is the disconnect while using WIFI that happens in a specific location without question. What needs to be understood is that there are two different aspects to what is going on while CarPlay is being used, 'audio stream' and 'phone projection'. Being in the IT field, I am always looking at the complete picture to figure out what is causing an issue. Here is the 'known' factors in this issue.

1. Cable doesn't matter. In most of these situations, the CarPlay feature has been disabled from the USB port. (I say 'disabled' and not 'removed' because it has been proven the feature can be turned on.)

2. The drop does not completely break CarPlay. It does completely break 'phone projection'. Once past the affected area, audio streaming will start to work again. Projection does not and will just show a black screen or the phone will fail to connect.

3. There is no recovering from the issue without shutting the car off and allowing the WIFI to power off.

On 'Point 1', like others, I have changed the CPU Variant in the Engineer's menu to turn the USB CayPlay option back on. In my case, CPU Variant 1 worked (4 did not). With option 1 selected, I got USB CarPlay but no WIFI option. I'm sure there are other CPU options that will enable both but didn't want to mess with it. I did notice that in the CPU Variant I used, my GPS when using Maps was acting a bit funky. I assume that is from some other setting that got enabled in that CPU Variant that the car didn't like or wasn't set up for. I did change it back to the original setting and the GPS issue went away. While using the USB CarPlay, I had no issues with the connection when driving through the affected area and had no assumption that I would. Side note, it looks like each CPU Variant is just a collection of settings for different car configurations. Each Variant will turn on and off settings based on the car’s features and options.

Point 2, You can tell that CarPlay is still connected by looking at the home screen on the head unit. Plus, if you were using navigation on your phone at the time of the disruption, your phone’s screen would be showing ‘turn by turn’ directions and not the map, as the phone assumes the map is being projected to the head unit.

Point 3, I haven’t spent much time on this one. Usually, after a ‘location’ disruption, I get to my destination, do what I need to do and, by the time I get back in the car, it works again. I have tried after getting home from work to spend a little time trying to see what is needed to get it to work again (I drive past the disruption point on my daily commute) but have yet to figure it out. In my car (2022 Kia Soul), almost every action affects the system. If I open the door and get in, as soon as the door closes, it fires up the WIFI connection and the phone is connected before I ever put the key in the ignition. Even the key has some affect on when the system activates or deactivates. After getting home, I have shut the car off, removed the key, opened the door (to kill the head unit), closed the door, locked the car, and then reversed the process, as if getting in the car to go somewhere. In that amount of time, the connection issue is still there. If I fire the car back up and try to project the phone, it will not. It is only after an unknown extended amount of time that it all works as it should. The only thing I can assume is that the WIFI or the system as a whole needs a few minutes to fully shut down. I have returned to the car in as little as 5-10 minutes and it will work fine.

In any case, these are the things I have found in trying to troubleshoot the issue. Whatever is causing these ‘area specific’ disruptions, it is, so far, an unrecoverable event, at least until the car has been shut off for a short amount of time. Rest assured, when I take my car in to get it addressed, they will have a very complete picture!! LOL

I owned a 2018 and 2019 Hyundai that to work you had to attach to a USB port and did not ever have one issue of losing car play but now have had nothing but issues with my 2021 Ionia which is wireless. I have tried everything but the one true way is to stop your car for about 5 minutes and restart and it reconnects which is somewhat irritating on a road trip.
