Siri not working with CarPlay after iOS 18 Update

Siri sometimes sounds robotic on CarPlay now when I text people using Siri. If I ask a random other question like Weather or sports then she has her normal voice. Not sure why the update caused this, but please fix it!!!

Exact same here - 2019 Subaru Outback. I just bought the 16 Pro Max, plugged it into the USB (with USBC adapter) and CarPlay is unavailable. I even deleted my phone and added it again, but with no luck. Is this an iOS issue or Subaru issue?

I have the exact same issue with a Subaru Forester '24. Phone 14 "Here is the most obvious symptom. When the iPhone is connected to the Subaru with CarPlay, if I ask Siri to message, my daughter, her name will pop up on the car’s CarPlay screen and the little circular glow thing is there, but it does not take audible input."

Same. Subaru Forester ‘23. iPhone 13 ProMax. Updated to iOS 18 last week. Siri worked fine until today. I ask her to read text message, she swirls and then the ‘Reply’ screen pops up. Anything I ask, she just swirls. As soon as I get out of the car, she responds as normal.

I’ve restarted iPhone multiple times. Checked all the settings suggested. Nothing corrects the problem.

Apple…fix this!!!

And…please, please PLEASE…fix the ‘You’ll need to unlock your iPhone’ when I ask what is on my calendar or agenda for today.

Siri Stopped working entirely after I updated my iPhone 16 Pro to iOS 18, when you call Siri, the icon will prop up, however, it will disappear as soon as you’re done speaking without any response.

what fixed it for me was simply turning the iPhone off and back on again.

although not the exact same issue I had problem getting Siri to do things and it would never finish its sentence and would just ask again. I found that if I tuned on the option "Require Siri for interruptions" in the accessibility options it fixed this issue and now I can send whats app messages and get Siri to read out messages again.

Similar problems after iOS 18 upgrade. 2022 VW ID.4 and iPhone 15 Pro Max, connected wirelessly to CarPlay. When Siri activates from the car system, for example to read a text message, the system freezes for about 30 seconds and then CarPlay disconnects and eventually automatically reconnects. When I try to use voice to text directly on the phone it also freezes and then CarPlay disconnects. Forgetting both sides, restarting and reconnecting doesn’t help. This makes CarPlay 100% unusable, I have to drive with the phone disconnected. I’m not using a VPN.

I have found in my Toyota 2023 RAV4 I have to say Siri twice for it to work. First time you get the bubble, but it takes the second Siri to get it to respond. I have my iPhone 16 Pro Max set to respond to Siri or Hey Siri. I am going to try setting it to Hey Siri to see if that helps.

Same issue, 2021 Subaru Crosstrek. So it works if you hold the talk button on the steering wheel or you push and hold the square at the bottom left of the screen. The "hey siri" feature doesn't voice respond back but siri does do what I ask just doesn't say anything. Example "Hey Siri, play spotify." She'll play Spotify but not tell me she's doing it. The biggest annoyance with this is talk texting because you can't review what is sending or when you need to hear what she's saying back to you such as confirming a reminder.

18.0.1 did not fix this, Apple please make sure 18.0.2 fixes this issue. Superrrr annoying!!!

I have also noticed that pressing the call answer button (on my Subaru), and then hey Siri, reverts to "normal" pre iOS 18 functionality.

However, we do need Apple to issue an update to fix this clear break in Siri functionality, which is compounded by an issue with Siri not working on locked phones, even when the option to do so is selected.

I have had this EXACT same issue with CarPlay since doing the update.

i’m kind of glad I’m not the only one having this issue. I have a BMW 330i and ever since I did the update on my 16 Pro phone will not listen to me in the car! Very frustrating!

Same issue. My iPhone 13 was fine with iOS 18 on my 2024 Toyota Venza. Upgraded to an iPhone 16 Pro and Siri no longer works. Same issue where the globe appears but I don’t hear a voice. Cannot send or hear text messages. I restart my phone and it will work for a couple days and then go back to misbehaving. I use CarPlay wireless.

I have a 2020 Honda Accord and, unfortunately none of the suggestions worked for me either. I deleted all of the CarPlay connections in both the phone and car side and still nothing. This is beyond annoying at this point.
