Siri not working with CarPlay after iOS 18 Update

I have experienced identical issues involving Siri and Apple CarPlay after installing iOS 18 on my iPhone 13 Pro Max.

Like some of the others who have commented on this issue… I also own a Subaru (2022 Subaru Crosstrek Limited).

On September 19th I contacted Apple Support. After numerous attempts to rectify the issue, it was decided to run a diagnostics test. The results were forwarded to Apple Engineering.

I was told by an Apple Senior Advisor I should hear something within a couple days or so.

Hopefully Apple will fix this issue!!

iPhone 11, iOS 18, Subaru Forester 2023. Same problem. Siri can't speak.

If I ask Siri something when connected to CarPlay, the Siri globe shows up, but Siri doesn't reply by voice.

Google Maps navigation works fine in that directions are spoken, but Siri is clearly broken after the iOS 18 update.

Disconnecting from CarPlay makes Siri function just fine. So it's a Siri + CarPlay + iOS 18 problem.

Since loading iOS 18, CarPlay in my 2023 Subaru Forester has not worked. Keep getting the Subaru screen to disconnect, wait, and reconnect. After doing this cycle about a dozen times, CarPlay still does not appear.

Tried different USB-C to USB-A cables with my iPhone 15 Pro, and the same Subaru screen appears . . . Disconnect, wait, and reconnect. Not thinking its the cables.

Even went thru the ‘forget this car’ by removing the car from my iPhone to no avail. After removing the phone, and when the car does appear to connect, it does give the screen on my phone about accessing CarPlay while phone is unlocked . . . But the disconnect, wait, and reconnect Subaru screen appears shortly thereafter. This tells me that it wants to connect and engage CarPlay; but something is still not allowing it to engage.

Also went into the Screentime settings to ensure CarPlay was checked to be an allowed app in the content and privacy restrictions. Still, the same disconnect, wait, and reconnect Subaru screen appears.

It seems there is something in the new iOS that is not allowing Subaru’s infotainment system to fully engage CarPlay. Please help!

I am also having this issue. Honda Accord 2024. Unable to activate Siri using voice.

You’re in better shape than me. Car Play won’t start since I upgraded yesterday. I’ve tried everything the support site says to do but 🤷‍♂️. IOS 18 broke Car Play. I hope the patch update comes soon.

This has been known about for way too long now. Life without CarPlay after living by it is awful lol almost dangerous. Nah I’ll just say it. Feels as dangerous as the days of searching for CD’s to play out of a case logic

So let’s try this again. My last post was removed, even though it contained GOOD NEWS?!

In regards to your workaround, people shouldn’t have to limit their privacy or change anything in order for CarPlay to fix. I’d have to try it to be safe, but for now the speaker button on the steering wheel is fine for now.

The next major update includes a fix. I’m testing out the first public release and Siri is working fine. I do not recommend trying it out unless you’re okay with any bugs, which I thankfully haven’t run into as of yet.

Please don’t remove this post Apple as that’s just plain censorship and I’m trying to help people out here by spreading the good news…

I have a 2018 Outback and everything worked perfectly fine until I bought the iPhone 16 pro with IOS 18. Now CarPlay is greyed out on the screen but it I hit the voice command on the steering wheel you can see the Siri animation on my phone.

Siri doesn’t work on CarPlay at all for me, no swirling globe. I have iPhone 13 on iOS 18.

it works fine otherwise and CarPlay works too

I have identical issues with my iPhone 16 Pro in 2024 BMW X5 after iOS 18 update.

Please FIX THIS!!

I downloaded ios18 and now I am unable to send or receive text messages in

in Apple CarPlay. It says this: Siri not available Siri requires a network connection. Everything worked fine on my iPhone 15 pro max before this

Some further testing. When I say “Hey Siri” on her phone it works. But her voice does not. It seems like the training is not applying to CarPlay Siri. It works for her off CarPlay but only for me during.

IPhone SE and 2020 Forester. Same kind of issues when trying to text hands free with “hey siri”.

I find that if while using CarPlay, I tap on “Messages” and manually select one of my contacts, Siri acts like she used to pre-update.

Not ideal or safe while driving of course, but it seems like it’s definitely a new update issue.

I have a Subaru Ascent and also ran into the same problem with Siri NO longer working with iOS 18. However, there is an alternative, where you can still use Siri with CarPlay, but you have to press the activate Siri voice control button by just pressing and holding the voice control button on the lefthand side of the steering wheel on a 2019 Subaru Ascent. This does work. Once you release the button, Siri will respond to your request. At least it’s a work-around, until Apple releases a new software fix.
