I have been noticing alot of rattles from in the cavern like the doors and trunk area. I mainly will hear the rattes over bumps and pulling into drive ways.
Is there any service that can fix them or maybe a known fix? Im planning of doing to rear deck fix this weekend.

where are your rattles? i've got them all over.

 

I get most the rattles from the trunk area a little from the doors and some from under the dash. Its very annoying going over bumps at low speed with low to no music ad hear my car seem loose Does Nissan help at all to fix these problems?

 

nissan will be glad to take your money. them actually fixing something is another story. you can try though. let us know how it turns out if you do.
