CarPlay issues w/ iOS 17.3

Like many others in this community, I am frustrated by the recent snafu with CarPlay. 2018 Nissan Rogue SL, with iPhoneSE connected via USB, was using CarPlay flawlessly until recently. Now, the phone function does not recognize my voice, nor does the navigation/Maps function. I use the voice button on the steering wheel, typically. Have tried almost all of the suggested "fixes" on this board. Fearful that perhaps the microphone is faulty but reluctant to involve the Nissan dealer quite yet.
