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.

The Bluetooth issues were talking about seem to be limited to UConnect systems, but it’s iOS 12 that seems to be the cause. No problems at all before iOS 12 came out.

I was able to talk to a Uconnect engineer...they're aware of the problem and are working with Apple as it's a combination issue between the iOS and the radio. Doesn't look like a fix is imminent.

Let us know when you have it installed. Would love to know your impressions. I'm on the fence about buying one as well.

Just over a week away from iOS 13 and hopefully this national nightmare will be over soon. Can't believe we've been driving around for 12+ months dealing with this BS. Fingers crossed.
