so the other day i started up my car and it sounded like a metal on metal sound like rat tat tat tat tat tat but it went away when the car was idle for like 20 sec and I havent heard it since. has anyone ever heard of this happening? I'm still under warranty so I'm good but is it a problem? gonna try to get it checked out this saturday

 

this has happened to me too a couple of times. im wondering the same thing.

 

yeah the funny thing is i moved my car the day before and it didn't do it but when i started it up the next day it was like rat tat tat tat... and after a couple of seconds when i was like what the **** is that i got out the car and popped the hood and it was already gone by the time i got out the car.
