In this article, we’ve gathered the most common noises that a car gives out. These hissing, slapping, shaking, thumping, grinding and sizzling sounds corresponds to a particular piece of the vehicle part that needs to get checked at the repair shop. 

a. Engine Noises - the moment combustion happens; this triggers the car to start accelerating. If the engine is working, there should be a steady hum of the engine’s pistons going up and down inside the engine’s cylinders. As the car moves faster, the car’s noise changes appropriately. But, if you notice or hear tapping, slapping or hear an occasional hum from the piston, it means that you’ve got engine trouble and its time to bring it for repairs.

e. Brake Noises - when you hear a high pitch squealing, it’s a sign that your brake pad needs to get replaced. Brake noises happen when soft-metal wear indicator rubs against the brake. The squealing sound is the metal grinding sound that means that brake pads may be damaging the brake rotors.
