First, make sure are you on iOS 13.1.2? That has a fix for bluetooth. Go to your iphone settings and forget your lexus. Then re-pair them.

exactly what guy said above, you might have to repair once or twice.. on my 2nd re pairing, my connection was good again

I’ve had Bluetooth issues since iOS 13 with all my devices. That could be a cause.

I had this happen on iOS 12, but found a fix. I believe that in the audio connection settings for the phone there are two options: 1) through phone, or 2) through bluetooth. I initially set mine to bluetooth and it would disconnect all the time. As a test I set it to through phone instead and that was much better. It no longer drops the bluetooth connection.

I had the same problem this weekend. Updated to iOS 13.1.2 and had bluetooth dropouts.

I remember back in earlier threads that using the USB with the iPhone could create crashes?
I was going to use the USB as a backup plan, until I can run the corrections suggested here.
But it seems that there are more features if you use the USB, like voice command song selection?

I am seeing a bluetooth device on my phone named CarAccessorySystem. Is that what should be deleted?
I assume not to delete the iPhone from the menu in the car?

Lagtime

Yes. It will re-pair as Lexus IS.

It worked. Thanks!

I had an issue in mine a few months ago. It was playing a song and kept cutting in and out, it frustrated me for a whole day. What fixed it was deleting the phone off the car settings. Then rebooting my phone completely, deleting it off saved devices in the iPhone settings, and repairing it.
