iOS 18 Bluetooth Connection problems

I purchased a brand new 2024 honda and two weeks later purchased new iPhone 16 pro max. CarPlay does not work. Gave a weird message “make sure hands free link is turned on”. I even switched cords and still does not work. Very frustrating

Your solution appears to be working. I was having trouble with both Carplay and BT connection in 2 vehicles and 3 differnt BT speakers in home and office. Also had issues when I would wake up the phone from sleep. All the above scenarios would cause the BT to cut out, seemingly random except waking up the phone or when notifications popped up when sleeping.

I have had drop out problems with Bluetooth connections constantly since iOS 18 I got a new 16 pro max and it started happening immediately cutting out on any Bluetooth connection,so not knowing what’s going on with this I still had my 15 pro max with a updated 18 iOS and it started doing this as well and until the update I use the Bluetooth daily with never a drop out till now, it’s all after the 18 update the 16 pro max only has 18 iOS but regardless it cuts out all the time while using Bluetooth on any Bluetooth connection as well so no question there is a problem with this update !

My apple watch works like normal but none of my Bluetooth devices will connect automatically I have to forget and pair again every time I use them or turn my Bluetooth off and back on again... sometimes both, and sometimes nothing works

Drives me nuts when the first step of basic tech is to be asked to wipe the contents of the phone or the cache. It is such a time consuming exercise and very rarely fixes the problem and then there is the huge task in front of you of re setting everything up. I am having issues with my new iPhone and its blue tooth connectivity. I have been happily using the iPhone 12 back and forth connecting to a variety of bluetooth devices including my car, Marshall speaker, sound bar and ue boom. Now it won't connect to my ueboom and is glitchy at best with most procedures having to be done multiple times before it works. I guess it's IOS 18 playing up? I forget the pains of a major upgrade to a new phone. It is NEVER as simple as we hope. Most of us love playing our music...so to not have this right is a super fail in the testing and release of these updates/upgrades.

Yep, I thought it was just CarPlay but using ear buds this morning mine does the same thing. Tried all the “fixes” I can find and nothing. Funnily on. CarPlay when the sound turns muffled old radio after closing screen etc, if Imake a call and hang up, most of the time the sound goes back to normal but first msg I get and boom, back to rubbish

Same here, iPhone 15 pro max after ios18, watch will constantly disconnect, Tesla phone key will not work. Tried wiping the phone, and installing latest version, doesn’t permanently solve issue. Restart helps for an hour or so. Very disappointed and phone is now out of warranty

Same here, iPhone 15 pro max, perfect phone ruined after iOS 18 upgrade and now phone warranty also expired :(

Apple watch will disconnect, tesla phone key is not working. Restart will fix issue temporary, wipeout and restore did not work:(

Apple watch will disconnect periodically, tesla phone key is not working. Restart will fix issue temporary, wipeout and restore did not work:(

I thought it’s my phone only. I tried everything including unpairing my AirPod Pro, forgetting the devices and Network Resetting. Nothing seems to work for long. Unfortunately now I’m not able to pair back my AirPod as somehow the case back button doesn’t seem to work. I’m left with a useless AirPod Pro 🤬

I was having the same glitchy problem with my Wonderboom 2 speakers since I upgraded to the iPhone 16 Pro Max with ios 18, but when I "forgot" the speaker and then re-connected it, the problem was fixed.

The same issue is on the iPhone 14 Pro Max running the latest iOS 18.0.1. Cannot pair with a bike GPS computer Hammerhead Karoo 2. It simply doesn't show up in the Bluetooth devices search list.

At the same time old iPhone 7 Plus with iOS 15 was able to find and pair gps computer successfully.

Hi everyone just bought a new 15pro 1TB on 2nd octobet. The device was on iOS 17.1 when arrivrd. My phone was slow and not responsive at times. All freezed hile using whatsapp. The updated to 17.7 the next day. After that I could see my battery percentage was really good. On standby at night when kept idle on 55 percent went down to 54 percent only. I was amazed but now when the apple executive at the apple service center as well as the person on the call said it's better If I pdate to the latest 18.0.1 i did it. I was very hesitant at first but i still took their advice, and now I'm facing many issues like battery is draining fast on my regular usage. As well as when connected to my car audio through Bluetooth before the update it was totally fine the other person could hear me but not its very bad, the other person can't hear me. When i started to talk to the apple support on call in my car she said I'm sounding robotic and not clear at all which was not the case prior to the update. Kindly give me a solution. This is my first apply phone and a horrible experience. Android is such a pleasant experience and things are done faster. I hope apple proces me wrong. The price i paid for this was huge so it needs to be justified.

Hi, have you found a solution? I no longer receive a text notification message on my cars screen (2017 equinox). I do not use CarPlay just Bluetooth. I have tried everything except taking to a dealership. I have an iphone15 with IOS 17.7. I am afraid to update to the IOS18

Just installed 18.0.1 on my 16 Pro. Still will not pair with my '18 Cadillac. Phone sees the bluetooth, has a matching pairing number, but when pairing initiated does not install into the CUE system. Phone says it's paired, but CUE says it's not. All my previous iPhones paired immediately. Apple: Ask Apple Intelligence how to fix it - please!
