The drama is that this is an entirely unnecessary step that adds extra work for the technician/owner that wants to change rear brake pads/rotors, which are a wear item.

I’ve been doing brakes on mine and my family’s cars for over a decade. It’s dramatically cheaper to buy pads and rotors and swap them myself, and if I do it myself I know that it was done right and there’s antiseize everywhere it should be. So now in addition to all the work of jacking the car up, removing tires, removing the calipers, depressing the caliper, cleaning the hub, coating the hub with antiseize, cleaning the guide pins, reinstalling and torquing everything to spec, I now have to get a battery/transformer/charger and wire into a sensor to tell the stupid fucking computer that the pads and rotors are new. Why can’t the computer use a position sensor to just detect that there’s now thicker material there? Why isn’t there just an option in the maintenance settings that you can press to say that you’ve done the work and to reset the maintenance interval? Fuck this shit, doing brakes is already a time sink if you live in the rust belt, and this system adds nothing but an extra cost or extra work to the person performing the work. There’s no safety gain from it existing, it’s fucking stupid.
