CarPlay is not working after iOS 18.4.1 update

I did a hard restart on the phone and manually made it forget the previous car connection - rehooked it up and I was finally able to get it working with its wired connection again.

Finally!!!

After updating iOS to 18.6 I did the following to fix wireless CarPlay in my 2023 Mazda CX-50:

1. Deleted the Mazda connection from my iPhones Bluetooth and wireless settings. 
2. Deleted my iPhone from the Mazda infotainment settings. *Settings > connectivity settings >  Bluetooth/Phone … > Delete paired device 
3. I then reconnected via Bluetooth on the iPhone. I also connected via the wireless even though Hotspot is turned off. 

I also lost my CarPlay connection to my Honda Accord with Iphone13 after upgrading to 18.4.1. Contacted Apple support and had me delete my iPhone device and reinstall. No help at all. Now it doesn't even recognize CarPlay as an option.

My Carplay also not working after 18.4.1 update. Hyundai i30 2017 model. Usually have to connect with USB cable not Bluetooth. Now it’s not recognising my phone when connected. I’m using an iPhone 14 Pro. My partner who hasn’t done the update yet can connect hers and it’s working fine. Not happy Apple! Sort it out. The irony of this update was that it was to fix issues that some people were having. Seems to have just made other people’s CarPlay not work instead.

Same issue, rebooted phone, deleted connection and reinstalled- will only detect BMW iDrive bypasses CarPlay and CarPlay never manages to send pairing code. Phone shows connection but reality is different!!! Frustrating 13ProMax with a 2020 BMW x3

Only Bluetooth and music remain connected after 18.4.1. CarPlay has stopped working with both my 16 pro and office 13 on my Mustang Mach E GT. No amount of forgetting the device helps. Car displays message that CarPlay is disabled on the iPhone

After the last update 18.4.1 my carplay stopped working in my Jeep Compass. It worked well before! Only my phone calls and music is active, but I cannot open the carplay dashboard. The Iphone 15 connects over bluetooth with my car and thats about it. I did reset my carconnect service of my jeep, reset the network settings of my phone, folowed several advices from Apple support, nothing works, yes Android does work smoothly!! Very frustrating.

• I initially could not get CarPlay(wired) to work at all, even after restarting the phone several times, and the car. The phone could charge and connect with Bluetooth just fine the entire time.
• I got CarPlay to work by deleting the saved connection/profile on both my phone (for the car) in CarPlay->My Car and the car (for the phone) in Settings->Connectivity Settings->Smartphone Connectivity Settings->Apple CarPlay settings"

Now it works, will see if it stays that way

Beyond annoying’ I had issues with CarPlay in the past. Got a suggestion online that fixed it. Did 18.4.1 update and it’s not working AGAIN! I’m so frustrated as this has been going on for over a year!

I drive a Kia EV3. Apple Carplay worked fine until I installed IOS update 18.4.1 on my iPhone 15 Pro. Now I can't connect in any way. I keep getting a connection error and the attempt to connect is aborted

I updated to iOS 18.4.1 yesterday and ever since I cannot connect to my head unit in a 2012 Grand Cherokee. It was fine until I installed the update. I've since tried all the recommendations others have offered, but yet I'm still not connected. I wish I would have not pushed the update through. Is Apple going to address this issue?

I've had issues with CarPlay disconnecting from my iPhone 16 Pro since updating to 18.4.1.

I've tried everything, but since 18.4.1 my CarPlay connection is flaky: if I touch the cable or drive over a bump, or in any way slightly wiggle the USB C cable it disconnects (it keeps charging though).

After trying everything (yes everything):

Clean port, new cables, resetting the car and the iPhone network settings, trying different phones running different iOS's, renaming my phone, turning off Bluetooth, VPNs, roaming, tethering.

I've even bought a very expensive USB A to USB C cable directly from Apple and it still disconnects.

I've narrowed it down to:

iPhones with Lightning ports running 18.4.1 are OK. (Lightning ports have a more secure fit than USB C).

iPhones with USB C ports running 18.4.1 all have the same disconnect behaviour.

It seems like the update made the USB C connection over-sensitive to even slight movement in the port.

18.4.1 had fixes for wireless CarPlay, it also seems to have introduced issues for wired USB C CarPlay.

The only thing that has me stumped is one phone (USBC iPhone 16 not running 18.4.1) also exhibited the disconnect behaviour.

I don't know whether updating my iPhone to iOS 18.4.1, updated CarPlay and then it also installed some sort of protocol in my car that now makes non 18.4.1 USBC iPhones randomly disconnect.

Although I know that CarPlay doesn't do this, it just mirrors your phone's display.

I guess we wait for the next update, otherwise I'm buying a wireless CarPlay adapter.

UPDATE:

For me at least - it’s Apple Intelligence.

I’ve tried everything - nothing helped. 

Then one cable (that had not worked previously) suddenly worked again (a Juice one). 

It worked flawlessly again, wiggling the cable did not make it disconnect. 

I thought about what had changed and I remember reading on Reddit that someone mentioned Apple Intelligence. 

I’ve tried restarting AI before and it didn’t work, but I remember that I hadn’t tried every cable, for some reason switching off AI makes this (and only this) cable work.

So I tried the other cables (to be clear these cables all worked fine in the past, prior to this issue starting), assuming they would all work, and here is where it gets weird. 

Trying the other cables didn’t work, but it also then made the Juice cable not work again. 

So I restarted Apple Intelligence again and it worked again. 

Looking at this logically, Apple Intelligence is doing ‘something’ to the information that it stores about cables. 

I don’t even know if it does that, I know it checks for MFi cables but does it keep track of each cable and then that gets confused by Apple Intelligence?

I just don’t know. 

So in summary:

1- Switch off Apple Intelligence 

2- Try every cable you have (a Juice one worked for me)

3- If or when you find one that works, try turning on AI and see if it continues to work. 

This might not work for others but it’s worth a try. 

Same here. iPhone 15 Pro max and BMW G30.

carplay was working just fine, after updating to 18.4.1 it no longer connects to my car. Tried hard restart, resetting network settings and removing phone from car and re-pairing, nothing worked … so frustrating!

Since the IOS update my Spotify has been cutting in and out or will stop playing for 10-25 seconds before it will resume through my Bluetooth in my car. I don't have problems using my Bluetooth in my house or my Alexia.

I've reset both and it continues to be an issue. This has never been an issue until this update 🥴
