iOS18 & Carplay Issues - Person I Call Can't Hear Me

Had a very very long case open with apple. Ended up going up to a senior technician and they needed more info, mostly device logs and timestamp of when it happened. So I did a call to Roger’s, I’m on Roger’s, and same issue. Low voice on other end. Had the apple person call me back, and we then processed to send logs from phone to apple. They can enable a link under the privacy in settings that sends diagnostic to apple. Sent with a couple pictures and the senior tech will have a look.

at first they would punt me to Roger’s. it I did that already and Roger’s gave me a case number. I told the apple employee I had a case number and they continued with the call.

I also took the car to the dealership and they reset the DCM, looked behind the dash to ensure no wiring is loose and they also looked for a firmware update, which there was none.

From my experience, it’s an iOS 18 issues. It does not happen on My iPhone X on iOS 16.

It only happens with calls between same carrier through apple carplay.

When I checked on the audio unit in the car mine stated up to date. When I checked the web site mine was way behind on releases and since Lexus is a division of Toyota I thought it could help. It resolved my issues with the web site firmware. Mine was a 2020 Toyota. Good Luck

make sure your audio unit has the latest firmware from the manufacture. Check via the website not the Audio Unit if it allows software updates.

You can still talk through Lexus Bluetooth—disconnect the cable for CarPlay and use the”talk” icon on your steering wheel. But that’s a workaround for a much bigger Apple iOS problem. Over 1500 users have complained. . .

I drive a 2018 Lexus Nx 300. Have the same issue. Tried using a different cable, restarted the phone, deleted carplay and paired again. No luck. Mine and my wife’s iPhone were working fine until the iOS 18 update. Now I have to yell in my car for the other person on the line to hear me. Hopefully Apple will fix this in their next update.

Calls are working fine when connected through Bluetooth.

I have the same problem with my 2019 Lexus NX300. I took my car to Lexus yesterday, 1-8-2025, and they are aware of the issue. I was told it is not working on some of their models but they do not have a fix at this moment, nor do they know if Lexus will do anything.

I have same experience, ever since IOS 18.x when connected with CarPlay the audio is useless. I turned car play OFF. Using the factory’s wireless connection and calls are fine. Apple need to Amit the issue and address it. This is creating distracted drivers!!

I have had an open case with a senior technician at Apple who keeps sharing my issues with engineers since October 2024 (or whenever the update came out). I have had no luck. I don’t know what else to do or who else to contact. I recently highlighted to the senior technician that it is obviously a same carrier situation that triggers this issue on Apple CarPlay (and not my Bluetooth) . I’m assuming the sr tech has escalated this (again) to “the engineers” but who knows. Maybe if more people call Apple this will get them to move.

If you do call tech support, make sure you get an agent who takes you seriously. I’ve never had this issue before the update and I remember they originally tried to brush me off as this being a service issue. The original senior technician I spoke to spoke to me like I was some sort of idiot and could not issue spot, implying that if I’m driving I could have bad service as the reason why this was happening even though I identified a clear pattern of occurrence.

I have the same issue except I'm in Canada.

I'm on Rogers and my wife and friends on Rogers cannot hear me or very low volume. Anyone else, another carrier, landline works fine. BT works fine.

I am having the same issue and I've tried everything. One thing that is weird for me is that people with Verizon can hear me, but my friends with AT&T cannot hear me. I also have AT&T. Also, when I connect via bluetooth and make calls that way (not using carplay) people can hear me just fine. I drive a 2019 Lexus NX300.

Hopefully Apple will do something. This issue is happening since the beginning of iOS 18. Seems like it’s independent of the car model or the specific cell service provider, it happens when both sides are with the same provider (probably it does not happen to everyone, but it definitely happens to me).

Same here. 2020 Lexus ES350. 3 months ago with IOS update no one can hear me on my phone when plugged into CarPlay. Only way to speak is to unplug and talk through the phone which I think is a major safety issue. Been in touch with apple support for 3 months. Senior tech just sent me a new phone and problem persists. I was thinking just buy a new Lexus, but as I am reading more posts it is an Apple IOS issue in my humble opinion. I also had Lexus check all the cars electronics and all is working and up to date. Anyone else had this issue and found a solution?

Same issue here after updating to iOS 18. Calls through CarPlay were working fine before, but now the person on the other end can’t hear me at all.Tried restarting the phone, switching cables, and even removing/re-adding CarPlay, but nothing worked.

It’s really frustrating, especially since Bluetooth calls work fine. Has anyone found a fix yet, or are we just waiting for Apple to address this in an update?
