Apple CarPlay keeps disconnecting (2021)

Turn off EQ

Settings —> Music —> EQ —> off

if that doesn’t work. General —> Reset —> Reset all settings.

I thought it was fixed after updating to IOS 14.5.1 but yesterday it just blacked out 2/3 of the way on my journey. Nothing would make it reconnect and when I reached my destination I could see all functions were on the car screen except Apple CarPlay which was greyed out. My friend had the same issue on her Ford at exactly the same time of day. Android play was available. After rebooting my phone this morning it worked again.

Looks like Hyundai just released a software update for their head units.

Did anyone (with a Hyundai that uses wireless CarPlay) try this update and can share if it solves the disconnect issue?

I will try it as soon as I can.

Have you checked with your dealer as to whether there are applicable firmware updates for your car?

A quick Internet search reveals there are a lot of Opel/Vaxhaull owners complaining about issues and have been for several years now.

Or they started using a feature that’s been in the wireless CarPlay protocol that those manufacturers did not implement properly on their side.

If that is the case, Apple is not going to modify their software to address it.

If they did break something, they will fix it eventually.

Have you tried upgrading to iOS 15 to see if the issue goes away?

iOS 15 was only released September 20, 2021, and it’s unlikely a new bug in CarPlay just introduced would carry forward from iOS 14 to iOS 15.

Further, Apple could not have broken anything “about four weeks ago,” because to change anything there needs to be a change in iOS, and iOS 14.7.8 was released July 26, 2021 and iOS 14.8 September 13, 2021.

‘’I have learned two Options.

‘’The First Option, Using your phone - Go to settings > music > EQ and turn on a choice of music, Play a song for about a minute but not on CarPlay—-on your phone. Then go back to settings > music > EQ and turn the EQ off. Plug your phone on and it should work.

If not your second Option. Is to reset back to factory settings. See if that will restore your phone go to settings and then General tap reset and and reset. all settings. Follow prompts.

hope that works

Hyundai offered me an ex gratia payment of $1,500 after I won the NCAT case. They didn’t want to replace the car as it would likely still not work, and they didn’t want to deal with NCAT again. They know full well this is a major issue, and have for all of 2021.

The $1,500 was to get me to take a refund on the car and buy a different one.

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.

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.

I’ve been having problems with this using wireless carplay on my Hyundai Tucson ‘21. Drops out connection - disconnect - reconnect.

Sometimes it will not reconnect unless you turn off the car for 10mins or more. So yeah, wireless is the future but I would definitely be using wires to make it work and prevent disruptions.

I have the same issue with a 2021 Santa Fe. Have had numerous calls with Apple to no avail. They feel it is likely a problem with Hyundai. Local dealer said it was a likely happening in a dead zone but a wired connection with android works . It would appear the router in the car should be improved to stop interference. Unfortunately the vehicle on supports a wireless connection for CarPlay and a wired connection for android

would appear the only solution is to buy an android phone

This issue has been ongoing since the onset of the wireless carplay. It does not seem to be resolving itself anytime soon. I wont make any recommendations as to what to do with your stereo, but following the video that is posted above worked perfectly for me. I no longer have wireless car play, but wired carplay works perfectly. I can always turn wireless back on if they ever fix the problem. CPU config 1 is the option that seems to be working for everyone.
