CarPlay Disconnecting - iPhone XS Max

I had my car in for service yesterday and service is certainly aware of the issue. As we've determined its on Apple's end to fix, so wondering if anyone is on the beta program and can confirm if iOS 12.1.3 beta 4 has addressed the issue?

Tried entering a bug report on the Apple site to try and get their attention but the submit button was greyed out LOL

Guess they do not want to hear about it !!

Will try again at home on a different browser.

I am not sure it will make a difference but I am willing to try what they suggest and if it does not work they will need to escalate to Engineering.

I also provided them the link to this forum in the chat so that they can see this is not an issue unique to me but far more widespread among different XS MAX users.

Thanks for the efforts! I will also call in for their support.

Just so you know, this issue isn't exclusive to iPhone XS Max. I'm running an iPhone XS (not MAX) and I am still having the same problem.

I should also note that while I am driving, I am always running Waze (usually with navigation) as well as one of music apps via CarPlay -- so the phone is under load - and not experiencing the issue. IOS 12.1.2 here.

Interesting suggestions! Thanks for posting them.

I will try the phone with a shorter (0.5m) genuine Apple cable, though it will make it impossible to view the device with such a short lead. I still rely on the screen of the phone for many of the apps I use via CarPlay.

I'm skeptical of #2 as not turning on Screen Time allows for all apps to run as normal. Turning on the privacy and security function requires enabling Screen Time, which further requires changes to be made to a number of settings that work fine presently.

I just tried item 2 and it did not work. In fact my car didn't even detect that my phone was connected.

(Side note: Disabling CarPlay in my cars menu settings allows me to at least use my iPhone as a normal USB device and music plays perfectly fine so it's definitely a CarPlay issue.)

Probably because uninstalling Apple Maps doesnt actually uninstall most of it.. All of the 3rd party nav programs (Waze, Google Maps, etc) have to overlay their own images on top of Apple Maps basemap on CarPlay.

I had strong expectations to this update but sadly, my iPhone 8 keeps disconnecting in my Audi A4 Allroad -18 after iOS 12.1.3 update. Same problem and procedure as before. Worked well for the first 4-5 minutes of drive but then it disconnects frequently until I unplug in frustration...Tried pretty much all of possible solutions mentioned in this forum and other....

I guess the next step is android...

Audi wont update my MMI version unless there is a fix to the particularly problem in the new version...

Tried airplane mode with IOS 12.1.3 today but no change to my problem, keeps disconnecting.

Next test is my iPhone 8 in an Audi A4 2017 year model version during next week...

Hmm, very strange...

I have tried genuine apple cable before with no luck. This time I’m was only using the Audi genuine cable, specified for this type of connection. I guess I can try one more time with apple one...

I have tried an iPhone 7 as well (but no CarPlay function only charging) with same result. Switching on and off charge randomly...

I have had a usb meter plugged in also, connected both separate and in between car and iPhone (some had this as a possible solution) but it didn’t work for me. However when I have it plugged in together with iphone and it begin to disconnect randomly, I unplug the phone, my car still keeps disconnecting the usb power meter/usb port randomly.

Could it be something wrong the USB ports in my car? Although they have these ports tested in my Audi workshop...with no errors...

BTW, Thanks for your support!

An interesting chain of events happened after I updated from 12.1.3 to 12.1.4.

My CarPlay connected in my KIA 2018 Stinger then disconnected then Connected then Disconnected and then Locked.

Had to reboot Iphone. My CarPlay connected then disconnected then stayed connected.

Before the update my Carplay was running perfect after 12.1.3.

What the **** happened iPhone support. Did you just decide to push the update from pressure or lack of ambition.

I guess the one thing that came out of it was SiriusXM did finally fully load the GUI on the CarPlay.

I'm not the only one getting frustrated.

Car Manufactures and Dealers are tired of hearing about problems as well.

I don't totally blame Apply Support. I also Blame the Car and Truck Manufacturers.

I had a n Android Phone one a long tme ago. They have unproved Tremendously. I do not want them to take over the Market place. I work at Lockheed Martin as a IT Sr. systems analyst and Integration specialist's Manager. I was involved in the migration to iPhone from Blackberry and Android.

Please this right.

Thank You.

I have this problem on iPhone X. Problem continues with 2 different GM vehicles. The disconnect send to happen more often when wired as opposed to Bluetooth. Volume always lose when wired. I start with a fully charged phone,

I have the problem as well. I had a 6s recently purchased the XR and continually disconnects from Car Play. Never had a problem with the 6s. I have a 2018 BMW X3 which is my daily driver. I am running 12.1. I also have a 2018 Ferrari California and have never had a problem connecting with Car Play. Thoughts?

Same problem. 2018 Audi A5 Sportback. Switched from an iPhone X running the iOS 12 public beta. No problems. Upgraded to an iPhone XS Max (256/AT&T/gold) running 12.0. Same problems as OP. Tried hard resets: did nothing to solve the problem. Did a full restore: nothing. Wiped the phone and started from scratch: nothing. Went to Genius Bar, reported the problem, got a replacement unit (same specs): nothing. Upgraded to 12.1 public beta 2 (the one that’s supposed to fix the charging problem, figuring it was related): nothing. Problem does not happen when plugging in my old X, my wife’s 7S Plus, or my daughter’s 8, all running 12.0.

There does seems to be some correlation between when the car’s Wi-Fi is doing something and when the CarPlay cuts out. Trying to figure out whether there’s a way to disable it (turning it off in the Audi settings doesn’t appear to be enough). Weirdly, if I put the phone into Airplane Mode, then connect it to the USB port, the problem doesn’t occur. (Of course, this is useless, since the phone is now offline.) But if I wait about five minutes and then switch it back to regular mode, the problem didn‘t return. Only tried this once, so I need more testing. Not sure what that would mean, other than to suggest a conflict betwen the iPhone’s Wi-Fi (or Bluetooth, or both) and the car’s.
