It just started and I bet its because it got cold and bushings inthe suspension are stiffer but whenever you go over a speed bump it makes this loud annoying sqweeky frickn noise sounds like rubber making friction!!My last 350zs never did it but this car does...anyone have this issue?Mines a 06 Sport..didnt do it til it started getting cold out...

also...ive searched for it and no answer...there any master reset for the bluetooth in this car...It wasnt hard to do in my 07 350..but my G is giving me a hard time adding my # and getting rid of the previous owners info

 

Not sure if this is the cause...but i will say: OEM bushings are rubber...I would replace your Comp. Rod bushing - I recommend SPL (metal)! I just replaced on my G - it will change your life! Night and day!

 

my car does the same, dont know how to fix it, sorry i cant help lol

 

Sounds like the compression bushings. Mine were covered under warranty.
