Just curious, I notice when hitting bad bumps or potholes on a road, the car will make a quick squeaking sound from the suspension it seems. I haven't noticed anything adverse just a quick sound. Nothing that bothers me, just curious if anyone else has experienced this. Luckily most of the roads here are nearly perfect, but there is a few bad ones.

 

My G37XS does the same thing...I can only hear it if the windows are down and I'm driving next to parked cars. It sounds to me as if its the shocks compressing very fast....like air/fluid movement in the shocks. I'd write it off as nothing/normal.

 

Thanks, I figured it was normal...Yeah, same thing only if windows are down

 

my g37x also does the same thing, although it's not an S
