Unless it’s the hardware that’s frying the NFC chip on iPhone 15s, which means wireless charging unit needs to be replaced.

Which is what I think is the case here.
I think the fact that a software update is planned to address the issue and that Apple technicians can restart NFC with a software tool, the hardware isn't getting fried.

I'm guessing the NFC power state isn't tied to the phone's power state for Express Transit purposes. A software update may implement restarting NFC when you boot up your phone to address this.

"the hardware isn't getting fried." - it could be. and they can be controlled to not get fried by a software fix. Software controls every part of a modern phone and its internal workings. Its possible that a particular operating point in the wireless charging is frying the NFC chip. Apple's fix will disable that point and choose another point, if possible, and prevent the hardware damage.

I guess it could be something that requires all affected iPhones to be physically replaced, but they mention:
Apple says technicians can attempt to restart the NFC chip in an affected iPhone by using a software tool part of Apple Service Toolkit 2.
 
Luckily, the charging tray in my G05 X5 is in such a silly awkward spot that I never place my phone in it anyways! lol

I often don’t use the tray for short drives, but I make a point of using it for longer drives. The phone tends to get warm in my pocket, presumably from engaging wireless CarPlay. Agree getting the phone in/out of the tray is awkward, but I don’t mind that it’s sort of out of the way since I’m not reaching for the phone until I’m leaving the vehicle.
