Hi all,

I was at a drive thru this morning with my window down, and am used to hearing my GS engine even louder. This time though, the sound wasn't normal. It sounded like a grinding/percolating sound. Car was in park.

The car still runs normally, and no light is on the dashboard for maintenance.

I am under factory warranty and have jerry's platinum warranty kick in at 50,000 miles.

Does this sound like an engine issue or a belt issue?
