iPhone 13 Pro loses bluetooth connection to car 2-8 minutes after starting a phone call

I recently purchased a new iPhone 13 Pro (then exchanged for an iPhone 13 Pro Max) to replace my iPhone XR. Here is the info on the problem I am seeing for your developers:


Hardware: iPhone 13 Pro Max, running iOS 15.0.2

Car: 2016 Toyota Avalon


Steps to reproduce:

  1. Start Car
  2. Allow phone to connect with car via bluetooth.
  3. Start a phone call
  4. Connection between the car and phone fails anywhere from 2-8 minutes after the call starts.
    1. The phone call continues on the phone, but the car thinks the call has ended. After this point bluetooth functionality no longer works properly until I restart the car.


Other details:

- The phone has no issues playing bluetooth audio to the car. Issue only happens on phone calls.

- My old iPhone XR did not have this problem, but was not running iOS 15.


Steps I have taken to fix the problem:

  1. Stopped/started bluetooth service on iPhone
  2. Enabled then disabled Airplane mode on iPhone
  3. Re-paired the iPhone to the car after forgetting bluetooth settings on both devices.
  4. Restart iPhone
  5. Force restart iPhone
  6. Updated software on car
  7. Reset all settings on iPhone
  8. Disabled 5G (settings -> Cellular -> Cellular Data Settings -> Voice & Date = LTE)
  9. Exchanged my iPhone 13 Pro for an iPhone 13 Pro Max, still have the issue


The iPhone is unusable for calls in my car which is really frustrating. Hopefully someone out there has seen something like this and has a solution/workaround. Or maybe this will make it to the developers and they can try and fix the issue.

All,

I am happy to announce that Apple Support contacted me this morning to inform me of update 15.2. This update has fixed my problem so far. No more disconnects during phone calls in my Tundra.


Please do this update and post your results here.


Thank you Apple Support for listening to our feedback!

Apple takes no responsibility?

There was no difficulty at all with my iPhone 7 but with iPhone 13 service is so spotty or even lately no Bluetooth connection whatsoever ? I’ve reset everything numerous times. Even with hooking up now my Know Your Drive (American Family) directly with a cable now iPhone is not being recognized. Is this the same problem or something different.

Car is a Toyota.

Similar issue in a 2009 Chevy truck, except that it seems to mess with iphone13 settings afterwards such that no phone calls can be made again until the phone has been re-started. Well, they can be dialed, but you can't get audio on the phone or in the car and the person on the other end of the call hears dead air. Maddening. I will be asking to downgrade back to the XS.

Thanks for the information, but this issue has to do with Bluetooth disconnecting during calls and is not related to CarPlay or wired connections.


Anyone have any luck with 15.2.1? I am not able to update to 15.2.1 at the moment try this out.


I have spent several hours working Apple on this. I’d estimate that I’ve recreated this issue about 10 times for them under different conditions with different settings. Each time providing them with diagnostics. Hopefully something has yielded good info for them to fix the issue.

You seem to think CarPlay has nothing to do with Bluetooth and phone calls? It’s all connected. And for your information Bluetooth calls still disconnect too. Also tried wireless CarPlay which does rely on Bluetooth on aftermarket head unit. It’s crap too. Disconnects after no more than 10 minutes on calls. Then when the call drops wireless CarPlay dies immediately.

I should have clarified. My response regarding wired connections was due to another post, not yours. I should have done two separate posts.


Your post only referenced CarPlay which uses USB (wired) or Wi-Fi (wireless). To my knowledge, Bluetooth is only used to setup wireless CarPlay initially and not after. At least that is how it works for me.


You have since mentioned Bluetooth in your follow up post, so you may be experiencing the exact same problem.

I’m having the same issue on my 2017 4Runner. Exactly as described by pudgemo. I can see from many forums that this is quite common. I did notice tonight however, as my kid spoke to my parents over FaceTime in the car, that the call never disconnected. This appears to be specific to phone calls. It is extremely frustrating and I already regret giving up my android. Please fix this quickly.

So frustrating! I had an iPhone XS, never had an issue with that phone on my car Bluetooth (2011 Toyota Highlander). Last week, I upgrade my phone to the iPhone 13 Pro, and this new phone doesn’t drop calls like you are all saying, I can’t even get on a call for a second. My music will be playing through Bluetooth fine, then I’ll get a call and the car audio/screen goes to “PAUSE” and my phone only lets me answer with regular audio or speaker. I don’t have the “Car Multimedia” option like I used to. I’ve done every trick I’ve read and it still won’t work. I’m currently using iOS 15.2.1.

Come on Apple! Please figure this one out, and quick.
