You're hearing a rattling noise from the belt assembly in your engine. The tensioner pulley is loose and shaky, and a piece of the alternator broke off, scattering metal shavings throughout the engine compartment. This needs attention soon to prevent further damage to engine components.

My car has been hacked. I know the hacker was able to get my VIN number bec he hacked my computer also (and I had to enter the information to setup autopay etc through my finance company). The hacker has been messing with the brakes which makes me afraid that it will force me into an accident. He is also messing with my RPM (I believe): there's resistance when I'm accelerating.
