iOS 18 (mostly CarPlay) issues

Thank you for posting this. Same issue with our 2019 Mazda CX-5. My wife and I both have iPhone 15 Pros and both running on iOS 18.0.1. This started happening when we upgraded to iOS 18.0. CarPlay crashes when we are using Maps and we have an active route AND when we are on a phone call. We haven't noticed any other situation that causes it to crash. I reported a bug on the Feedback app but of course have heard nothing from Apple.

Identical issue with my 2020 CX-5 Signature, using a 16 Pro running 18.1. CarPlay quits right after using Siri to text or call a number. It does, fortunately, send the text or make the call before quitting. Then I have to unplug, replug, and CarPlay works fine again until I use Siri to text or call. I'm not sure if this bug is consistent with all Siri-activated commands, such as requesting a specific album on Apple Music. I've been using CarPlay in this vehicle for over 4 years and never had this issue until the new phone and iOS 18. My wife has a 15 Pro that's still running the latest version of iOS 17 and there are no issues with CarPlay.

I have tried all of the suggestions to resolve the issue and finally found the one to turn off Vocal Shortcuts. I do not have Vocal Shortcuts enabled and never have, so that is not a resolution for me.

If anyone has any other suggestions, I could use some. It would be nice if Apple was a help with this, but that is never the case.

Both my wife and I just got the new iPhone 16pro with iOS 18.0.1 now installed, and Apple CarPlay will suddenly quit when we use Siri to make text messages or phone calls. We have to unplug the iPhone and plug it back in and then it usually works. We're both using the standard 1m USB-C Apple white braided cable that came with the phone. The cars are 2018 Mazda CX-5 and a 2017 Mazda 3. No VPN running, and we restart the phones everyday.

I have the same problem with my Lexus 2021. I can hear my caller through CarPlay but they cannot hear me and I have to use the speaker function on the phone. Called Apple and they were no assistance. Never had a problem until update. I also noticed that I’m not get vocalized map directions. It seems like there are enough complaints with various car models that it would appear to be a an Apple problem. One odd thing today: Called someone with android phone and they were able to hear me through the CarPlay. Apple users could not.

Since downloading IOS 18, no one can hear me when I call them - or they hear me from very far away. I only sound normal if I switch to hand-held/speaker phone mode, which defeats the purpose of the hands-free Apple CarPlay system. I've tried most of the suggestions - none have worked - and I have never utilized Vocal Shortcuts - that feature is turned off. I own a 2019 Lexus UX and commute 90 minutes per day - I would really like Apple CarPlay to work. BTW, my maps function works just the same as before - just some things look different.

Have you done the basics? Checked to see if your car headunit has an update? Turned off VPN on your device if you have one (it is a known issue that has existed before iOS 18 for some users)? Restarted your device? Contacted Apple directly for support (via chat/text/phone)? Whatever may be going on for you and some others it’s not a universal issue affecting all CarPlay users but would still need to at minimum be reported to Apple in case there is a bug that they can address. I personally have had no issues with iOS 18 and CarPlay (wired or wireless) in any of our household vehicles with the new iPhones or with older iPhones updated to iOS 18

UPDATE So I did everything recommended in this thread and nothing worked. The only solution that worked was to go to my Mazda dealer and have them update the Mazda Connect software. I just did it today. Cost me $87.50 😐 but now the problem is fixed. I can now text or do any voice commands without it crashing.

Yes! I thought it was just me, but since the recent update I have been having an ongoing issue with Car Play disconnecting. It often does this after sending a text, but also has dropped randomly from time to time and just did so while on a call. What a complete pain. I have tried every solution that I have seen online, including resetting the infotainment system. I hope Apple and Mazda can figure this out and get a fix. It is a complete pain and really makes Car Play only moderately functional.

I’m having this problem now with my brand new 2024 Nissan xtrail. I just updated my ios today to 18.1.1 version and my CarPlay won’t work properly. Can’t skip songs, can’t use Siri, can’t get phone calls anymore or text messages. I’m really really annoyed. I didn’t just upgrade my bloody car to have a dumb automatic iOS update go and mess my system up😭

I can also confirm that I've tried all the solutions suggested here and none of them has fixed the problem for me.

I’ve been having the same issue with my 2018 Mazda CX-5 as well. Using Apple Maps, or just Apple Music. Then when replying to a text. It crashes when sending.

Fixed my issue. After upgrading to ios 18 my car play was not working correctly. I drive a Jeep Grand Cherokee which uses uconnect to control my entertainment center. Car play ios 18 was muting my volume and acting funny on phone calls. I contacted apple care 3 different times. Each time I spoke with 2sd level supervisors. We worked through all the logical settings with no luck.

I googled the issue and found one person who discovered that you should try turning off "Vocal Shortcuts." I had set up a couple vocal shortcuts I deleted them and turned vs off. Worked for me. Go to settings-accessibility scroll down to Vocal Shortcuts and turn off. I also deleted car play from my phone and my Jeep and reinstalled just to make sure. Resolved my issues. Hope this helps.
