Apple CarPlay Not Working in iOS 18.0

Allowing carplay in content and restriction resolved the issue for me I read here  that carplay needs to be allowed in content and restrictions and in my settings it was disabled I’m not sure why it changed since I didn’t modify any settings before the update.

I suggest first removing your car from the Bluetooth connections on your iPhone and then forgetting it in the settings under General > CarPlay. After that, try pairing again. If that doesn’t work, resetting the network settings on your phone can help clear any connectivity issues.You might also find this guide helpful:

After the ios 18 update, I was driving and mid-way through the drive my carplay disconnected and refused to connect again for days. My mom’s phone that is the same age and has ios 18 connected, but not mine so I knew it wasn’t the system or the cord. I went through all of the fixes on the apple side: privacy and siri enabling, etc. and nothing changed. BUT Here’s what actually worked: 1) under general > carplay, click on your car and make sure carplay is allowed 2) if #1 doesn’t work: delete your car from carplay in your phone in your car (scary but worth it), then delete all of the phones paired including yours in the carplay system on your car (mine was under connectivity >smartphone connectivity settings) 3) plug your phone back into your car. when i did this, suddenly i was offered the chance to reconnect. So, I want to uplift that working through the connectivity/ smartphone settings in your car is key. When I was just doing the apple side fixes nothing changed.

I have a Honda 2020 CRV. Nothing here worked or I missed it. I went out to ask a mechanic a question and they asked if I reset my infotainment system. Nope, didn't know I could. Press and hold the Volume Button for 10 seconds and it reset. After that it allowed me to always enable CarPlay and my phone and my daughter's phones showed up, connected and it worked. My big concern was maps for driving. I tested it to be sure maps worked and it did. I swear I have tennis elbow from holding my phone for days scrolling through so many sites! I hope this helps someone else.

This is what worked for me.

Hyundai Ioniq, CarPlay was fine last night on iOS 18. Phone updated overnight and car play stopped working completely. I reset my car unit, forgot the car in CarPlay, turned everything off, etc nothing worked. CarPlay didn’t even see my car. Resetting the network settings brought everything back.

Check out “Vocal shortcuts” under accessibility and turn it off, it solved my issue

CarPlay (wireless) working as expected on my 2024 Traverse LT and iOS 18 on my iPhone 13. We’ve taken several trips now and it performs perfectly well. Suspecting this issue is with your vehicle that may require a firmware update. I do notice that your screen shot is for Google maps. Do you have the same issue with Apple maps?

I have a 2023 Hyundai Kona electric. I reset the screen by pressing the small hole next to the screen’s right-hand dial with a sharpened pencil. It’s to the right of the arrow that is to the right of the dial itself. It’s the only thing that worked.

My Content and Privacy Restrictions were off for some reason also. I went under Screen Time in settings and toggled that on.

I had the same problem connecting CarPlay with IOS 18.

i shut off vocal shortcuts and that fixed the problem. To get to vocal shortcuts go to settings/accessibility/vocal shortcuts.

Got it working. My solution was:

Update to 18.0.1, delete all cars from CarPlay, delete Bluetooth pairing, delete my iPhone from the car. Turn everything off and on again (hard restart iPhone). Re-pair phone.

Seems back to normal now.

I had this same problem and doing a "Reset to factory settings" on the car radio is what fixed it for me.

I have three GM vehicles (two 2017 Chevy Cruzes and a 2019 Chevy Traverse) that I had been using with my iPhone XR via CarPlay for years. When I upgraded to an iPhone16 Pro the Traverse and one of the Cruzes worked immediately, but the second Cruze wouldn't recognize the phone via CarPlay no matter what I did. After two days of fiddling I finally did "Reset to factory settings" after which it instantly recognized the new phone.

I had this problem as well. I have a Nissan 2023 and I went to my apps and found my iPhone. I toggled it to see “always” when it asked about usb and CarPlay. It was set to “never”. Thanks to Ms/Mrs. Elise from apple support for the help

Good news somebody here posited a fix and it works. I am one of the users with a 2019 GM. Using an iPhone 15 Pro Max since updating to iOS 18 using CarPlay causes the head unit to freeze go blank and reboot every single time.

I tried three different Apple OEM USB-C cords that came with iPhones and an iMac. No success.

Then I tried a 12 inch third-party thunderbolt three cable. These cables are made to tight tolerances and lower impedances. Apparently that cleans up the signal and allows everything to work normally something between iOS 18, and some GM vehicles is causing it to be very sensitive to the cable.

hope this helps

Turn off your “vocal shortcuts” under accessibility settings on your iphone!!! THATS the ISSUE

I had the same issue. The issue for me was that I’d run out of Apple cloud storage! I deleted a backup to free space on Apple Cloud and then it worked.
