Apple CarPlay on iOS 17.3 is not resolved, the same problem with iOS 17.2.1 still exists

The new iOS 17.3 has no remedy for the problem with Apple Carplay, I had to turn off Apple Car Play on my BMW X5 50e (model year 12/2023) - deactivate it.

The following errors still exist: After receiving an iMessage, Siri speaks, it plays, but when trying to respond via Siri, the iPhone 15 Pro Max disconnects from the vehicle, reconnects after a few seconds, but the music performance then Reduced by more than half (50%), you deactivate Apple Carplay only then does the muscle performance return to normal directly via the car software.

The typical attempts like resetting the vehicle entertainment software, the rest of the network and BT settings or the best of all support ideas, completely resetting the iPhone with a complete reinstallation of all data, pictures, music, banking apps etc of course does that doesn't make any sense or the problem is solved.
