help!!! my 2008 honda fit sport manual has a terrible rattle coming from the passenger door area - only at lower speeds/stopped, and when going over bumps/potholes (in boston, that's all the time..). any suggestions are appreciated!

 

Pop the door panel off and have someone else drive the car while you sit in the passenger seat trying to find the noise. If there is no noise after panel removal then investigate the door panel and see if anything is loose.

 

I've had the metal ring that the door latches onto go loose in the rear passenger door. Tightened the screws and it was all good. Maybe check that?
