It's really hard to understand what you're asking here."What causes a knocking sound when your car drops into a hole while driving?"If that's your question, I imagine that it would be the sound of your car dropping into a hole.
A drop in your revometer, speedometer, and temperature gauge while driving could indicate a problem with your vehicle's electrical system, such as a failing alternator or a weak battery. It might also suggest issues with the vehicle's Instrument Cluster, wiring, or sensors that provide data to these gauges. Additionally, overheating can cause a drop in performance, which might affect these readings. It's advisable to have your vehicle checked by a mechanic to diagnose the issue accurately.
