The Bambu printers do some cool stuff with measuring resonance to detect lubrication and belt tension issues. This is theoretically possible on any machine that can do Klipper's inout shaping, but requires a LOT of data to be useful (from what I understand), which is probably why we don't see many printers on the market that can do that.
For thermals, Marlin (one of the popular printer firmwares) actually evaluates the control response of the heater and thermistor, rather than just looking at a specific temperature range. If the behavior is sufficiently different than what the system is tuned for (not heating up at the expected rate, difficulty maintaining temp, etc), it will throw a temp error and shut down before thermal runaway occurs. I would expect other modern firmwares (e.g. Klipper) do this as well, but I don't have as much experience tinkering with them and don't want to make definitive statements.
Can confirm, klipper does this too. Sincerely, someone who had a few thermistor related wire breaks.
