Siri not working with CarPlay after iOS 18 Update

I have a 2023 Honda Accord and also have a non responsive Siri after ios 18-18.1. The voice button on my steering wheel has never been able to activate Siri. I’ve tried all the above solutions. Only solution: every time I start my car, once the head unit comes online I need to soft reboot the unit. Siri then works until I shut off the car.

Having the same issue with my iPhone 13 paired with a 2021 Forrester. 

i think it’s a Hey Siri / Bluetooth/ IOS 18 / CarPlay issue. Bluetooth /IOS 18 works, so does it work when I use the steering wheel controls with Bluetooth / IOS 18 / CarPlay, but have never ever ever used the steering wheel controls until today

Tried re-paired my phone to the car and same thing

I updated my 2021 Subaru Forester’s software hoping it would solve the issues with Siri . It did not. It’s definitely a Subaru issue since all my stand alone devices work perfectly. I have a stand alone CarPlay unit for my old car and it worked perfectly after the iOS 18 update

So, my wife’s 2016 Mazda 3 works flawlessly, so it’s something in the implementation that Subaru, and now Honda, use to facilitate the phones connecting to the QNX CAR platform the iPhone uses to display CarPlay

Does anyone have any news on this? I’m still having issues where issuing Siri commands via CarPlay like, “Hey Siri” brings up the response trigger animation on the infotainment center, but following up with “Text XXX” just brings up the individual you want to message, but she doesn’t reply back and it’s almost like it times out. Using the button on the steering wheel works, but it’s a pain to have to use it for every single command. I did not have this issue until iOS18. I know there was a recent update released by Subaru, but I haven’t received it nor do I know if it addresses the issue. For reference I have a 2019 Subaru Sport 8” Non-Nav Infotainment system. I’ve DFU my iPhone, unplugged the negative terminal from my battery on my Subaru for 15 minutes, re-updated via usb the last update issued by Subaru, but nothing works. I’ve reset my infotainment center as well…what’s going on?

I have the exact same issue with a Subaru Forester '24. Phone 14

jai Pas reçu le nouvel mise à jour et je voulais l’avoir si possible

2024 Honda crv… iOS 18 car play connects but when I ask Siri to call anyone he keeps saying “to who” even though I’ve already said who to call. Fix this Apple!!!

After trying a phone reset, multiple cables, and resetting the head unit I decided to purchase a brand new cable that said it was for CarPlay and it worked immediately.

For my girlfriend this was due to Messenger. So check you don’t have Siri enabled for too many apps.

I try to disable most apps that offer integration unless it makes sense.

Don’t buy the cable that was linked above. did not work either.

Just to be clear, for me this is a CarPlay issue. I used wireless, sometimes Siri answers, at least half the time it doesn’t. I’d like to think 18.1 fixes it. It is pretty fundamental

I too tried everything folks suggested and recommended and sadly nothing works.

now just hoping Apple listens to its stakeholders and gets going with the fix 🙏

Easy fix to rectify this.

go to settings/general/carplay

delete vehicle/s

then re add car to CarPlay and fixed

i have a 23 Crosstrek and have to do the exact same thing. Frustrating
