is it normal on cavaliers for the suspension to squeek and creek and stuff like that or is it because it is brand new.

Its just normal. Get it mostly while turning by chance?

I get a little bit when its really cold out, but thats about it.

once it warms up, if it continues to squeak and make poping noises... you have bad strut mounts or a loose nut somewhere.

I hear it when I am getting in and out mostly. it hasn't been cold here and there is no popping just creeking.
