Feels like a good opportunity to in addition to having the normal system diagnosis, have a process that listens to the sound the car makes and recommend bringing it into the shop if the sound sounds weird or off.

Samsung appliances do this I think? Or some other brand.

You basically call a number and then press a button on the appliance and it produces a sound that tells the customer service what's wrong.

Some ACs use exactly this method. Haven't found any other household appliances that use sound for diagnostics.

This really is a tremendous idea and if vehicle software engineers were better they might actually be able to do it.
