CarPlay Disconnecting - iPhone XS Max

UPDATE: Have been using USB y-splitter (https://www.amazon.de/gp/product/B009EAF0RU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&language=en_GB&psc=1%29) for past month, not a single disconnect since. Power (red) plug is connected to car's second USB port.

@allen134

I don't understand why should a Y-Splitter make any difference? Does it have power-management capability?

Others mentioned USB-Meters fixed their problems - I ordered 4 different Meters - no success!

I should add that I first purchased the car in October of 2017 (although a 2018 model). At that time I had an iPhone 7. The issue never emerged until sometime after I upgraded to an iPhone XS in September 2018.

It is difficult to determine if the cause is the iPhone XS, an iOS software issue or an update to the Audi MMI. The car has been in for routine service at which point the MMI could have been updated, but I can’t be sure. Unfortunately Audi points the finger at Apple and provides no assistance to solve this issue. We as the consumers are the unfortunate ones with brand new cars and phones that don’t work properly. Please help Apple.

What year and model of Acura?

I tried Bluetooth off, but that didn’t help.

Today I tried deleting my memorized vehicles from the CarPlay settings. In other words, it should be a first time fresh connection. I wonder if a glitch occurred in the connection history? Haven’t had enough drive time to test it.

I solved the problem - at least for me. I have a 2018 A5 which was working just fine with my iPhone X but disconnects regularly with my xS Max.

Until - just the other day - I tried a genuine Apple lightning cable. And voila, problem is solved. I am suddenly having no issues at all, can run as many apps as I want. I even tried running Waze and Apple Maps at the same time and it was rock solid.

I have generally used high quality third-party cables (usually Anker) and have rarely had issues elsewhere. But all I can say is try the genuine Apple cable and see if it helps. It worked for me.

I also only use genuine Apple cables and I am still having the problem.

I was first using the Audi branded cable that came with the vehicle. This worked perfectly for nearly a year, until the problem started happening. I thought maybe the Audi cable was failing so I switched to the Apple branded cable. The problem continues.

Jeep Grand Cherokee Summit and iPhone XS MAX

Confirmed my Uconnect is latest version so upgrade available on the car side.

Same issue. Totally regret upgrading from my iPhone X which was stable with CarPlay. Too bad I traded it in for the XS MAX so now I am stuck as I cannot go back.

Apple, this is a brand new yet defective phone what can we do ?

Same! I'm so frustrated. I have an Audi 2018 Q5, it cuts off and on during maps and text and everything else. Never had the issue with my iphone 7. I don't see any response for fixes. Apple please help us!

Totally hit and miss at the moment for me. Had a full day of use with no issues at all yesterday......today, worked for 5 mins, then nothing.

Have ordered a Y-splitter to try, but resorted to BT Audio now as a workaround.

Hopefully apple will role out updates to manufactures soon.

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.

Reported via "Contact Support". They accessed my phone remotely, ran diagnostics and confirmed hardware was OK.

I was asked to forget the car in carplay settings, test during my commute tomorrow and then have a call with them scheduled for tomorrow afternoon.

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.

Have not had this issue on my 2018 Audi S4 with my XS Max. I use CarPlay daily and all the time while I drive. My car was built in January 2018, and had the midyear change where one USB port is in the console and the other USB port is in the front next to the cigarette lighter. I am using the USB port closer to the front next to the cig lighter, with a 1 foot aftermarket Lightning cable.

Has everyone experiencing this issue using the USB ports in the center console only? Are there people with the USB port up front like I have that are experiencing it? Has anyone tried a shorter (i.e 1 foot) Lightning cable?
