iPhone 17 Pro Max Carplay Keeps Disconnecting

I just upgraded from the 15 Pro Max to the 17 Pro Max. My 15 rarely had any issues with CarPlay but my 17 I can barely keep CarPlay going for 2min before it disconnects and then refuses to reconnect. I’ve done all troubleshooting steps and nothing works.


Wireless Carplay


Troubleshooting done:

Reboot phone

Removed Car Connection

Factory Reset Infotainment System

Re-paired

Checked for updates

Disabled auto join of other WiFi networks.


It will connect but then shortly after disconnect and refuse to reconnect again.


This needs fixed as I use CarPlay everyday for my job.

iPhone 17 Pro Max, iOS 26

Hi Everyone,


I finally got so fed up with the problem being even worse after the latest IOS update, that I started a ticket with chat support. They ran me thru trouble shooting, then told me that they needed a senior tech to look at it. They offered me a phone call. I scheduled the phone call, and the two techs who attempted to call me kept disconnecting and couldn't hear me. After this, I chatted back to support and requested they set me up an in-person appointment in store, and they did.


I went to the Apple Store, they were so kind and understanding, and one of the guys who worked there told me he ad his wife BOTH experienced this and it was a software issue. They recommended a backup, and to do a "reset" through their computer which includes completely removing the OS from the phone and then reinstalling it from their master OS in their computer there. The way I understood what they were doing, is that it were as if I were building a new PC, and installing windows for the first time ever on a blank hard drive.


They told me that the software that I had even though its the same "numbers" probably has some bugs in it, and it is best to just start fresh from scratch.


When they did that, I was skeptical, but it fixed every single problem. And I notice that voice to text works better than it had before, and that everything is generally quick.


So a complete reinstall of the OS at the Apple Store is what I recommend. It's worth the 3 hours I spent at the store, because I spent way more time than that troubleshooting random ****. And a software re-install and repair is indeed different than just factory resetting the phone.

Yea my 15 PM worked no problem for years as well and in multiple vehicles (wireless). I switch to the 17 PM and in 2 different vehicles now (wireless) it does the same thing just disconnects randomly. I have to turn on Airplane mode on and off to get it to reconnect.


I did just plug in (wired) this morning and no issues at all. I purposely got a wireless Carplay unit because I hate wires and now i'm being forced to use them. Extremely frustrating.

Well I thought I would speak to the manufacturer of the Car Play unit I have in one of my cars a Porsche Cayenne, A very helpful company called Integrated Automotive and they said there seems to be a worldwide issue with the new iPhone 17.


They suggested I follow the following steps:-


1.            Update to the latest ios 26.0.1

2.            Reset network settings on the phone, this fixes the issue in most cases, make sure you perform the following operations:

a.            Delete the iA_xxx bluetooth connection from the iPhone Bluetooth menu.

b.            Go into the IMI-1000 Bluetooth menu and click on the “trash can” to delete all phones.

c.            Turn phone off.

d.            Turn car off.

e.            Turn iphone on and got into setting/general/reset network settings/rest/reset network settings (note that this will wipe all wifi/Bluetooth connections).

f.             Power phone up and re-pair to the imi-1000 bluetooth.


And low and behold today I have done 3 x 30 minute car journeys and the carplay has not played up once!


So fingers crossed this has sorted it!
