My 350 has about 2500 miles on it now and already I'm plagued with rattles. First it started as a faint noise comming from what sounds like the rear wiper area (although hard to tell when your driving). Now in conjunction with the first rattle, I seem to have a quiet sqeeking sound comming from the drivers rear suspension. It only makes the noise when the *** end of the car squats when you depress the throttle reguardless of speed. Any ideas out there? Has anyone had similar problems or noises? Please respond... it's driving me mad!!

 

Your car is still under warranty....send it in for inspection.

 

My rattle on my ZR was the jack equipment which is encased in a foam gizmo, I just rearranged the equipment in the foam.
