iOS 12 Bluetooth Uconnect issue

I updated my iPhone 7 to iOS 12, and immediately noticed that there is now a significant lag in song selection when connected to bluetooth in my car's Uconnect head unit. When a new song plays, the song run time is frozen for exactly 30 seconds while the song plays. If I try to toggle next/last track selection using the car's audio controls during this time, nothing happens until the 30 seconds pass, then it changes to the next song. It happens very consistently now with every new song that plays. Also, during some songs it'll do this freeze for 30 seconds where song navigation won't trigger.


Can't overstate how annoying this is. Has anyone else experienced this?

This issue started for me after I upgraded Uconnect to 17.43.01 on my '15 Grand Cherokee on 10/2. I had iOS 12 on my phone already, and I did not have the delay before the Uconnect update. The delay in the radio controlling the phone usually was 30 seconds, but sometimes would be better. There was no change in behavior with the 12.0.1 iOS update.


I did a hard reset of the phone today (vol up, vol down, then hold the power button), and now the issue is almost gone. I did have one instance of a delay at the beginning of the pairing, but it went away after a song or two. It's possible that a hard reset (not a power off) will help some of you.


It will be interesting to see what iOS 12.1 will bring.

I also have these issues. 2013 Ram 1500 with up to date Uconnect software. Following an installation of iOS 12 I have found that music tracks randomly skip while connected to the Uconnect system through Bluetooth. Podcasts played in the Apple Podcast app also are experiencing an issue where after some variable period of time the podcast skips back to the beginning and starts playback or sits idle. I have also seen this occur with Audible playback while connected to the Uconnect system. This issue was not present until updating my iPhone X to iOS 12. Using Bluetooth connection through AirPods has not yielded any of these issues with either music, podcasts or audio book playback. The problem seems limited to the Bluetooth connection with Uconnect. Based upon other comments in this forum string it seems highly probable that the iOS update is the root cause of the issue. Hopefully Apple gets the message and puts a fix in the works soon. It is very distracting to have this happen while driving which I’m sure we are all trying to avoid by using these products.

I posted earlier about having this problem. It all started when I updated to ios12. I did try to delete and reinstall the phone about 3 times. I am enrolled in the Apple phone renewal program where I get a new phone every year. I received my new phone last week. Guess what? No problems. The problems are only with existing phones doing the update. Not new phones that come with ios12.

So did I. My iPhone 8 was updated many times during the iOS 12 beta period through the final release before I got my iPhone XS. It started having problems around iOS 12 Beta 4. My iPhone XS was running iOS 12 out of the box, and had the same issue. So the issue is occurring with multiple devices whether they were updated to iOS 12, or ran iOS 12 out of the box. The update part doesn't seem to matter, but the common denominator is iOS 12 regardless of what hardware it's on.

So I was FINALLY able to connect my iPhone X to my 2018 Jeep Grand Cherokee with 8.4/Nav Uconnect this weekend. I went into Bluetooth settings and clicked the "info" button next to Uconnect and selected, "Forget this Device", then turned off Bluetooth all together. Then I switched BT back on and selected Uconnect at the bottom of the screen. Then I was able to pair my iPhone X to my Uconnect. I am on iOS 12.1.1 and the latest Uconnect update.

I don't want to jinx it... but ever since I installed iOS 12.2 Beta 3 on my iPhone XS, this problem has disappeared. I've driven in my truck several times over the last two weeks since installing it and have not had any issues when skipping through my track list. Beta 4 came out today, but I haven't installed it yet. I'll post back in a few days once I've installed it and tested it out a few times. Hopefully it stays fixed, but it wouldn't be the first time that the issue appeared to be fixed on one iOS release only to be broken again on the next one.

I also have this issue and unlike other "solutions" provided out there that talk about rebooting the phone and resetting Bluetooth, I found that it is *NOT* a phone-specific issue. I made the mistake of updating my iPhone 8-Plus to iOS 12 when it came out, EVEN THOUGH I knew my iPhone XS was arriving that very same Friday.


As soon as I updated my 8+, I was having Bluetooth issues. Song/track skipping could take up to 45(or more) seconds... the voice prompts from Siri seem to have bad audio quality as if the signal was poor or dropping... also, need to repeatedly connect MANUALLY to get my audio to work when I get in the car.


I was HOPING this would go away when my NEW iPhone XS arrived... but as you can predict; NOPE! I am still having this issue. It is extremely frustrating having to constantly re-connect the phone manually in UConnect and to wait for song skipping for LONG periods of time. The commonality is iOS 12.

I've been having this issue for the last couple of months, ever since iOS 12 Public Beta 4 or 5 on my iPhone 8 started doing this in my '16 Ram Rebel. On my iPhone 8, I tried forgetting the bluetooth connection on both the phone and UConnect, and doing a factory reset of UConnect, but neither of those things helped. I also updated my UConnect system to the most recent release that came out a few weeks ago while I was still using my iPhone 8, butthat didn't fix it either. I thought it might get fixed once I got my iPhone XS today, but it's having the same problem in my truck. Once again, redid the bluetooth connection from scratch, and then tried a factory reset of UConnect. No luck. Hopefully someone can figure this one out quick because it's incredibly irritating to have to change tracks from my phone's lock screen instead of being able to use the steering wheel controls. Changing tracks from the phone's lock screen, or from the music controls on my Garmin watch works just fine, but the UConnect screen and controls still lock up until the song I stop on has played for 30-35 seconds.

I have been experiencing the same issue in my 2015 Jeep Cherokee Latitude Plus ever since I updated to iOS 12. I thought updating to iOS 12.0.1. might solve the problem but it did not. Almost every time I listen to music in my car, the media info on the screen will freeze for exactly 30 seconds before it allows me to change the song via the touch screen or using the controls on the back of the steering wheel to skip songs. I can change songs as much as I want if I use my iPhone, but the info on the screen will stay frozen. I have updated my uconnect to the most recent update, forgotten the bluetooth device from my phone and car and re-paired it, and even just got a new phone today, but still no luck. I have no issues when using USB port for music, only when using bluetooth.


Hoping Apple is working on a fix because this is simply annoying.

For what it’s worth, the latest iOS 12.1 beta seems to be better. I’ve had 3 decently long drives this week after the beta was released and I can skip tracks without issue for the most part. If I try to skip through more than 7 or 8 songs it will lock up the UConnect display and controls, but that’s better than it happening all the time. This is also how I first started experiencing the problem around iOS 12 beta 4. A few betas later is when it started locking up the UConnect all the time. Hopefully we’re getting close to a full fix.

I bought a Ram truck with the Uconnect sytem back in June, 2018. I have an iPhone X and never had any problem with either. As soon as I upgraded my iPhone X to iOS 12 I started having the same type of problems.


I have a family Apple Music subscription and I REALLY notice it more when I playing a large playlist, (like over 50 songs.) I don't see the issue at all if I just play songs from my downloaded music library. Very frustrating.

So for comparison's sake - over the last few weeks, I've had the opportunity to connect BT to a '18 Grand Cherokee with the latest 8.4" head unit as well as a '19 Ram 1500 with the big 12.1" screen. Both worked flawlessly over the course of their respective weekends. (The Ram BT had a separate issue where it disconnected and would not read my phone as available at all, but that seems unrelated. Or maybe not, who knows.)


Basically, this tells me that there's something which changed with the new iOS12 which plays poorly with some older Uconnect systems but nicely with the newer Panasonic units (but not all.) So still at square one - wish Apple would engage FCA and figure this out already.
