iPhone 15 Pro Carplay disconnects

It's all about the data transfer rate.. Cable need to be 10Gbps...

A Thunderbolt 3 cable works.

Hello Hollythelab,

If you are also able to test using a USB-C to Lightning Adapter that may help based on the details below:

You can use the USB-C to Lightning Adapter with wired CarPlay in most vehicles. However, some combinations of adapters, cables, and vehicle entertainment systems might disrupt the wired CarPlay connection. In this situation or for cars that support only wired CarPlay, use a direct connection with a USB cable.

The additional steps below may also help:

If your iPhone is updated to the latest version of iOS, follow these steps—checking CarPlay after each step:

1. Check your connection to your CarPlay stereo:

• If you have a wireless connection, make sure that Bluetooth is turned on on your iPhone under Settings > Bluetooth. Then go to Settings > Wi-Fi, and make sure that Wi-Fi is also turned on. Tap the CarPlay network, and check that Auto-Join is turned on.

2. If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display and select it.

3. Restart your iPhone and your car. 

4. Make sure that Siri is on.

5. If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions. If Content & Privacy Restrictions is on, tap Allowed Apps, and make sure that CarPlay is enabled.

6. Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.

7. Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.

You can find those details and steps in this resource: If you need help with CarPlay - Apple Support

Should that still persist, you'll want to reach out to Apple Support: Apple Support They'll be in the best position to look into this further.

Take care.

Which cables did you order? If i could post video here I could show how sensitive any USB-c cable is with Apple Carplay.

If I hit something in the road like a crease or a driveway transition that sends a small shock through the car...it loses connection.

Yes Lightning 'held' better and didnt lose connection with apple carplay but the other benefits of USB-c still make it a welcome addition to the iphone. The transfer speeds alone are worth it but also the fact that it's saving me clutter and the ability to use the same usb-c cable for 99% of my electronics is awesome.

I haven't tried the official braided USB-C that came with the phone since my carplay uses Usb-A...but maybe i'll try a USB-A to C adapter and see if the apple braided cable is worthwhile.

I seen someone post about using a SAMSUNG cable and sure enough I’ve had the best luck with it. It’s crazy how it works better than the cable that comes out of the box. I still miss lighting whether it’s faster speeds or not. I’ve tried Anker, the Apple one and an off brand off Amazon.

I finally had some luck with my disconnect issues with my iPhone 15 pro max and my Sony car stereo with WebLink and apple play.

I bought a new light cord and also found out that there’s a newer WebLink app available. Once I upgrade to the new app, it seems like everything is working fine.

I’m including a link to the latest WebLink app. Hopefully it works.

Yeah, I’m having problems too as sometimes if I put it in driving mode before I turn the car on and plug it in it seems to work for a while. Also, there’s some settings in driving mode that have CarPlay options in them. In your drop-down menu of phone modes, there should be three little dots to the right of driving mode and the other modes, and you can go into the settings of that mode.

Same issue with iPhone 15 and 17.3 iOS wired CarPlay AND wireless bluetooth to car's infotainment (not wireless CarPlay) in 2019 Audi.

For CarPlay - Many USB cables tried (all those recommended here, all failed). It is not an initiation issue, but an issue of maintaining connection. Will occur whether moving or bumped, etc).

For the car's infotainment bluetooth phone connection - also occurs randomly. It will connect and stay connected for a random period of time then disconnect for a few seconds and then reconnect. This will repeat many times during a call.

Neither issue (CarPlay or Bluetooth) has ever happened on earlier editions of the iPhone (13, 11, etc) that I owned and used in this car. Only the 15 pro max on iOS 17.

Because it affects only the 15 and it affects CarPlay and non-carplay (bluetooth) functions, it appears that it is either the phone (15) or the iOS 17.

"In a nutshell this is intended to prolong the life of the battery by learning your personal usage and charging cycles and only charging the phone to 80% until it considers you are going to be using your phone shortly and it recommences charging to 100%

Anyway, this afternoon I turned this optimisation off and CarPlay has worked faultlessly for over two hours when before it was crashing every ten minutes or so. "

Tried this. Doesn't help. Battery was 30%. Not a solution. Only solution I have found is to have a well-charged phone. Personally, I suspect a hardware issue. Class action anyone?

I had the same issue but I ordered some data type cables off Amazon I haven’t had any issues since

I tried in 3 different cars and it works in all of them with older iPhones and didn’t work in any of them with iPhone 15 Pro. Obviously the problem is in the iPhone 15 Pro.

Try disconnecting your phone and power off or get a new Apple cord.

I’m having the exact issue. From day one receiving the new iPhone 15 Pro. Previously had an iPhone 13 Pro with no issues. Tried multiple USB to C adapters.. there seems to be no rhyme or reason, but consistently disconnects from CarPlay. Contacted Apple and they didn’t seem to have any real solutions. I explained that this seems to be a very troubling safety hazard, especially if I was traveling long distance using Apple Maps very discouraged. Based on my troubleshooting, I think it’s a bug that needs attention ASAP

It is easy to duplicate the issue.

Have maps open and running.

Have music playing using any app on your phone.

Wait a while for phone to get a little warm.

Then try and make a phone call.

This will overload the phone and turns the car play off and on.

Never had any issues with my previous phones.

Same! I've had no issues with the iPhone 13 Pro Max, but I've encountered consistent problems with my iPhone 15 Pro Max's CarPlay connection. Despite using USB-A to USB-C cables rated for data and charging that are advertised as compatible with Apple CarPlay, my connection is often unstable - connecting for 3-5 seconds and disconnecting in an infinite loop. It might last only a few seconds at times, and yet occasionally it works perfectly fine with the same cables. Could this inconsistency be background app status or battery dependent? This connection issue poses a significant safety concern that could lead to car accidents and casualties.

There are countless online reports highlighting this same issue, and it seems to be especially problematic when the battery is low. Additionally, when a connection is established, I've noticed that the skip button in my car no longer fast-forwards songs, but instead can only skips them.

Beyond the CarPlay concern, the iPhone 15 Pro Max has a myriad of other issues. For me personally, these include a randomly lagging keyboard, inconsistent home Wi-Fi connections, and poor AirPod audio clarity. Callers often struggle to hear me, a problem I never faced with the 13 Pro Max. The automatic cloud data transfer from older iPhones (e.g. 13 Pro Max) to the new iPhone 15 Pro Max has also been problematic for many. In my case, while my iMessage conversations transferred, many embedded pictures did not. This has resulted in the loss of cherished memories that were in some convos only. There's also a glitch wherein cropping a 4K video reduces its overall quality upon saving, this was not the case on 13 Pro Max.

I've been a loyal iPhone user since the iPhone 3 and have consistently opted for the higher-end models. It's disheartening to see the quality decline over the years, especially given the rising costs. For a phone priced at $2400, one would expect an enhancement over previous models, not setbacks. Apple, please address these concerns promptly.
