Noise / vibration coming from the back.

[Isilwen]

Hello, my first post here.

I bought a CR-Z EX on february this year. Satisfied with it even if the battery tends to die way quicker than I would like to

Anyway, some months ago this weird noise appeared all of a sudden. It seems some kind of metal-against-metal "clicking" sound, that comes from the back. It's always there, but I noticed it's heard more clearly when driving on uneven/shaky roads.

Unfortunately I work all week and I can't take personally the car back to the dealer. For this reason I had someone do it for me, and the dealer apparently fixed the problem saying that the back hatch was a bit loose, and something else about the muffler.

Thing is, yesterday this noise reappeared, after a 200km trip.

It's incredibly frustrating. I tried to pinpoint the noise myself but I couldn't. It's driving me mad.
It's my first car and I like it to be always neat and quiet, and this noise is really making me consider to sell it -_-

Did anyone here had a similar problem?

Thanks a lot for your help.
