iPhone 13 keeps disconnecting from car bluetooth

I had the same problem and it got solved by resetting my network settings then forgetting all the Bluetooth devices that are still saved in the setting.

It could be that if you had another phone synced via Bluetooth to your car radio, you may have to delete that device and then add a new device for your current phone.

My dealer said the same thing two weeks ago, I updated the app today, updated the firmware in my driveway… deleted and re-paired and I’m fixed.

15.4 seems to have solved the connection issues with my Audi.

15.4 seems to have sorted my BMW, cross fingers for my wife's Audi.

I have had persistent bluetooth issues since the iPhone 12 Pro and now the same with the iPhone 13 Pro for phone calls. My airpot pros, and both my Audi handsfree connections seem to be affected. I have worked with apple support, changed the phone, AirPods, updated Audi software, removed added all Bluetooth devices, and even started my most recent phone as new with no backup. Multiple iOS updates over the past year have not helped either. On calls when there is poorer signal the bluetooth connection starts cutting out such that I hear every other word and the same on receiver side. I switch to speaker and all of this distortion disappears. If I immediately connect back to the Bluetooth device, the distortion resumes. After a little time, when I reconnect it seems to resolve. This is very frustrating and can happen multiple times in my car. I have noticed it is much worse in my car when driving so I wonder if it related to the ATT signal, 5g, etc. I am very frustrated at this point and don't know how to actually use my phone in a proper way. Using the Bluetooth has allowed me to be safer when driving, traveling etc. Sometimes I miss my Nokia, the calls were never an issue

I have the 2nd gen airpods. I called support today and luckily it happened 3 times while on when them. Each time was almost 40 seconds long so it was perfect. During this call I didn’t have a case on so no interference. Support had me do a reset all so we will see what that does. They also had me turn off my Apple Watch in case it is causing the conflict. I’ll respond back on my progress. If this does work, they are going to ship me a new phone. Do you guys all have apple watches?

Okay…cautiously optimistic…I upgraded to 15.3 and have made 4 calls from my car, plus had a friend call in. Everything seems to be working so far. I will update again in a few days.

I talked to 4 Apple support people (at different times) plus a Support manager and no one admitted they’d heard this issue.

Exact same issue with audi MMI. randomly droping bt connection, i have to manually disconnect bt and reconnect when im driving then works fine. But if i wanna cancel call on phone is canceled but on mmi system still shows connected. Then bt connection drops again with iphone XS was no problems.i13 is upgraded on 15.3.1 ios.

I have also disconnected my watch and other nearby bluetooth connection leaving only the car bluetooth connected.

@Moose_OSU I thought the same thing. I was having this issue with both of my vehicles; a 2018 Tacoma, and a 2012 BMW. Updating the phone to 15.3.1 seems to have resolved it, so I thought life was good again. But took the bmw on a trip last weekend; no luck with bluetooth. Had to resort to talking on the device.

I wonder if 15.3.1 update targeted Toyota systems? Will be interested to hear if other Toyota owners are seeing the same thing. Of course according to Apple, apparently there is no problem. I have yet to find an Apple support rep to acknowledge that others are having this issue.

Almost same issue here. Not able to connect my iPhone 13 Pro to my VW Touran. The phone shows up but refuse to connect. Just tried to connect to a Geneva Touring radio via Bluetooth. Not connecting there either. Tried to reset all settings on the phone but still not working. This is really frustrating. Next is to reset all content on the phone but trying the longest to avoid it.

100% won't work with either my Amarok or TOUREG R Bluetooth. This must be fixed. It's a major safety floor and I'm sure I will not be the only person who holds Apple responsible if there is an accident cause a driver looks at their phone / speaks on their phone... let's hope it gets fixed. I've troubleshooted everything!!

I just bought a new iPhone 13 pro max and the Bluetooth feature is super frustrating. It connects to my Toyota Highlander but will hang up on people at random intervals as I’m talking with them. Spotify will work and then cut out as well. I have researched this issue and tried all of the recommended ways to deal with this problem but none have worked. Can you help?

Well, part of me is happy to hear I don't need to deal with the headache of calling tech support at Apple because it is a known problem and apparently no fix. But the other part of me is quite annoyed that it is a known problem of several months and no fix has been made.

I just wanted to add I have the exact same issue, my Bluetooth calls drop within 2-8 mins (although music apps are not dropped via Bluetooth) and I have reset everything (I will not go through the headache of a factory reset!), re-paired my Bluetooth, and all of the other suggestions including paying $75 to have the software on my 2017 Toyota Tundra updated by the dealer and have the latest and greatest IOS 15.1.1 update on my phone - nothing fixed it.

Very irritating given the exorbitant cost of the Iphone 13 Pro and it doesn't work as describe!!! (Another class action suit could be on the horizon like the battery throttling of the Iphone 6 and 6+).

I have made my 3rd call to support, each time Apple has taken logs. Last night 11-30, we spent over an hour working the issue. I have a 2017 tundra, I drive around while Apple recorded the phone logs. It dropped calls numerous times during the support call. Once again I have a follow up call with a senior advisor next week. I don’t see the issue getting fixed anytime soon. Fingers crossed
