Apple CarPlay Not Working in iOS 18.0

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.

i have my IPhone 15 updated with iOS 18.0.1 and the Apple CarPlay is not working in my Mazda car. Every time I start the car, the carplay doesn’t connet through bluetooth. If I delete the phone and connect it manually, it works but after I turn off the car and start it again, the same happens. The Carplay doesn’t work by bluetooth and I have issues with the wired connection as well.

Yep this is what mine does. IF it works initially, just touching the screen on the phone will cut the sound, my steering wheel controls won’t work to change anything, music is like it’s coming thru a toilet roll at the end of a hallway, and sound keeps dropping out totally for a sec or two every few min.

I have an opposite issue than what people mentioned here. Apple CarPlay works with the USB cable but doesn’t work with Bluetooth (get a connection error message). I have IPhone 12pro and my car is a Toyota Highlander 24. It was working before updating to IOS 18. I tried all possible suggestions but with no luck. I can blame it on Apple.

I still can’t get my Apple car play to work at all and have not had any help from Apple Steve jobs would have had this fixed . I really need Apple CarPlay please fix faster I really use car play as lot . I can’t believe that Apple is not carrying about CarPlay any more . I am going to the Samsung store today to look at a new phone if this is how bad Apple programming is now . Not a happy customer

mkrabill, the exact same thing happened to me using Apple Car Play with my Lexus after updating to iOS 18. My wife's phone still works normally in the Lexus using iOS 17. I ended up following a YouTube video and reverting back to iOS 17, and voila, my phone works with Apple Car Play in the Lexus once again. On the flip side I did not have a backup on my Mac/iTunes of my phone with iOS 17 so I lost all my data/settings etc. I'm working through that issue now as I do have a backup on my iCloud but is with iOS 18. Anyway, I hope I can get everything working normally again.

Never had any of the voice stuff enabled to begin with. Carplay connects, and works for the most part. It is, however, buggy. The steering wheel button to engage Siri doesn't work anymore. Certain popups, like reminder or alarms, at times, cannot be dismissed without using the phone. On iOS 17.x everything worked 100%, 18.01, not so much.

Hello!!! I FOUND A FIX!!!!!!

I was having the exact same problem after updating to IOS 18. I was able to fix it by going into CarPlay (settings>general>carplay) and went to “Forget This Car”. The next time I plugged my phone in, my car and phone prompted me to allow CarPlay and I simply clicked “Allow” and bam! Worked!

We had the same issue for my wife’s 2023 Audi Q5… this video helped. Please watch and apply the entire video and you’ll hopefully be up and running.

Same for me. In one of our cars, it worked for a while and then stopped. In the other car it won't work at all, Vocal shortcuts are not on nor is my VPN. The weird thing is that it looks connected in the car, but only plays through the phone speakers. It will not connect to Bluetooth. It looks like it might connect on the phone for a nanosecond and then immediately back to not connected. How can it look connected on the screen and not be connected to Bluetooth?? I have a road trip coming up and NEED music and maps!

Reset your network settings: Settings>General>Reset>Reset

Network Settings

Restart your iPhone and restart CarPlay

(If you have a virtual private network, turn it off)

Rename you iPhone: Settings>General>About>Name

Try to reconnect with your CarPlay

If that doesn’t work, got to iPhone Settings>Siri &

Search and enable Listen for “hey Siri

Then, go back to Settings>General>CarPlay and make sure

your car is listed

If your car is listed, remove it and try to re-pair

If that doesn’t work, go to your iPhone:  Settings>General>CarPlay>Forget this

car

 If that doesn’t work, back up your phone to your computer or

the Cloud and do a factory reset.

Good luck!!!!

Still nothing from Apple. I've contacted them several times, up to 7 times in fact. I've been on the phone for hours with Apple Support to no avail. We have completed every troubleshooting option out there. Still waiting on Apple to correct the bugs. MADDENING. I wish I knew how to directly speak with a decision maker to get this fixed NOW. I purchased the wireless car play and that works ok for my maps but spotify is in and out constantly. I even purchased a new phone. I've seen on this chat stream customers who own 2023 and 2024 vehicles having trouble. So it really doesn't matter which car you have. This is 100% an APPLE PROBLEM.

The newest iOS update on the phones has made CarPlay worse. I talked to Subaru they said sometimes the car software itself lags behind and recommended I check back with dealership in December to see if an update has been pushed thru to help.

I have tried this reset and it work now this is the solution after you update your iOS from 17 to 18 and above.
