I have a 2013 Fit Base with about 4000 miles on it (5 M/T). Have started noticing a noise coming from back seat area that sounds like if you had a glass bowl and were rattling a spoon or something in it. Sorry, that's a lousy description, but that what it sounds like to me. I checked where the spare tire is to be sure nothing was loose. Also checked the back seats to be sure they were secured. Hear the noise especially over bumps. Am also wondering if something is loose under the car and would cause that noise.
Any ideas? Thanks!

I still love my Fit! Ain't no stinkin' crash tests gonna make me switch......

 

I had that problem, turned out to be the emergency jack and/or tools were loose in the spare tire well.

 

I had something similar and ended up putting some grease on the rear seat latches (the bar it locks onto where it locks upright) and that was the problem. They were secure, just made noise.

Over killed it with Mobil 1 high temp grease I had sitting in the garage lol the problem hasn't returned though.

 

Thanks for the comments. Turned out to be the tool bag by the spare tire. Took care of that!
