When I first got the car I noticed that when I would go over a speed bump or pull into a parking lot that had a grade the rear of the car would make a "bong" noise that sounded like a spring. Last night that sound was louder than before and now it's making all kind of noise. Every thing feels OK and nothing is hang down but it sounds as if something is lose. Anyone else had thiis problem?

 

Check to make sure your exhaust is not loose on the back. You wouldn't feel it in the suspension but it would make noise as the chassis flexed.

I'm not sure how many supports/hangers there are, but you shouldn't be able to move it much by grabbing the tailpipes (Don't do it when it's hot!).

Never heard of any other issues like this...keep us posted.

Have your dealer check the suspension A.S.A.P. You may have a loose shock or broken bolt.
