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.

Same issue for me. Many previous iPhones worked flawlessly, iPhone 17 Pro Max disconnects every few minutes. Tried changing every WiFi setting to my CarPlay device. No effect. My wife’s iPhone 15 ProMax works perfectly connecting to same hardware.


come on Apple many car manufacturers rely on CarPlay functionality now so this is a big deal especially on a flagship phone.


There are too many people with the same issue with this phone across disparate devices here for it not to be you, sort it out.

I am having the same issue. I have opened a bug report using the link provided here. Just letting folks know. I think it is for Apple to fix. I am on a iPhone 17PM with all the updates applied. I have a Tesla and am using the Hansshow screen that worked fine with the 16PM I had. My dad just pinged me and he has an older phone with iOS 26 and has no issues. Thanks everyone.

I too have the same issue, I almost ended up crashing my car because my Apple CarPlay got disconnected right before my turn, and I was not sure if that was my turn, So I have to take sudden turn Almost crash, another car to avoid adding 10 more minutes to my drive.


This is pathetic, You pay so much money for Apple’s flagship phones, and you have to go through this issue.


my phone keeps disconnecting from my wireless CarPlay every 30 seconds, i am sick of it. I have done everything online, nothing works.

I am encountering the same issue with my CarPlay functionality after upgrading from an iPhone 15PM to an iPhone 17 Pro. When connecting via a wired connection, CarPlay connects and disconnects every 2 minutes.

I never had any issues with CarPlay prior to this phone upgrade.

Im starting to worder if this is my phone, the software, or my car?
