Since updating to iOS 15.3, my car won't stay connected; bluetooth keeps connecting and disconnecting

First my wife had exactly same issues with her 2013 Audi TT, and within a week my 2013 A3 was doing exactly the same. She has iPhone 13, me and iPhone 12 both in same version of iOS.

Apple…..what you up to????

I have a 2014 BMW and an iphone 11. I spoke with Patrick at Apple for at least an hour yesterday, resetting the network, reconnecting to bluetooth, etc., Still a problem, but he hadn't heard of it before and is working on it. I expect to hear from him the end of next week and will post an update. SO frustrating! For me, if I try to use Siri to dial, no sound whatsoever out of the speakers and I can see the call connected on the iphone screen. Can't talk because can't hear...and then call drops.

So, this is apparently not limited to only car bluetooth for calls: I just got off the phone with my sister. I was listening to a podcast with Tozo earbuds for about an hour. When she called, I clicked through and talked for about 3 minutes and then it disconnected. I called her back with Siri and it didn't connect for audio, although she could hear me. Then the earbuds disconnected. I ended up talking with her directly on the phone, then re-established a Bluetooth connection for the podcast with no problem. So this is a Bluetooth by iPhone PHONE issue only. I have Verizon. I don't think it's the service provider, but please post who your service provider is so that Apple technical support will have that information as well.

Thanks.

The same problem I have with my Audi Q5 2019. BT worked simply PERFECTLY till I upgrade my iphone 11 with iOS 15.3.1. Now I'm permanently suffering of problem of unpredictable behavior of BT - phone it loosing BT connection in a middle of conversation, after re-connnection it manualy the same problem repeating again and again. I tried unpairing/pairing of device - helpless. I tried by pairing with another iphone 11 (iOS 15.3.1.) - result exactly the same.

Apple support, do your job, please fix a bug ASAP!!!!!!!!!

Or we need to downgrade our devices??????

Congrats, Octavius8. 6 weeks since your first post…

Did you “Forget This Device” (your car in BT settings on your phone) and/or delete the phone from your car and then re-pair it? Just curious if that’s necessary? It’s probably a good idea, anyway.

I am having problems with 15.4.1 connected to a 2017 Audi.

It connects perfectly but if anything interrupts the audio then nothing works.

e.g.

I connect & play music over spotify. If I receive a call while listening to spotify the call will work fine, but when the call finishes BT doesnt work, no spotify or no phone.

Another example when watching youtube while connected to BT (dont worry....not while driving), when an add is played on youtube the audio often drops after the add finishes

I have exactly the same issue, Audi 2011. Come on Apple ! : )

In my second car I have the same problem with bluetooth.

My wife doesnt update ios to 15.3 (she has 15.2.1) and bluetooth works fine.

Apple please make some update to solve this.

Having problems with Tesla and GMC truck. Only with my husbands 12 pro max. My 12 pro isn't having any problems.

I have the same issue!

2 Audi from 2009 and 2010.

iPhone Xs and iPhone 12 running iOS 15.3.1

Same issue. Bluetooth keeps disconnecting. 2011 Audi A4. Tried all the original poster did, plus reset network settings, no fix.

solution for this is new ios but apple is

blocked this info. Mayby 8th march will be new version of 15 ios

iPhone13 Pro Max on 2011 BMW with the same. Seems to be a pretty widespread issue. How was this not tested? Huge safety issue and legal with some state hands free laws.

Well after update I still have the same issue.. ended up not using Bluetooth with phone. I just decided to use a usb cable…

Similar issue trying to use my phone as a key for my Tesla. Toggle Bluetooth on and off, it works, 2 minutes later it disconnects, 10mins later it decides to connect again. Network reset performed, no change.
