5k miles and multiple noises.

Hey,
I have a 2008 Prius that is experiencing a few abnormal noises.
When I "powered down" my Prius tonight, I had 5651 mi on the ODO.
Most have been highway miles. I have no modifications. The only difference in my car from how I recieved it has been the gas in the tank. ;-)

1. I hear a "chirping" noise coming from what sounds like the rear-suspension. This occurs at highway speeds when going over a bump or when traveling slow speeds AND turning over uneven pavement.
Sounds like what I am used to hearing from suspension parts being worn out. But at 5k miles????

2. Rubbing noise- slow speed. maybe front tires?

3. rattling from interior components/finishes?
Coming from lower drivers side door and maybe passenger footwells. Is this common in Toyotas? My 10 year old Camaro would seem to be better than this Prius in that respect. Or is my Prius abnormal?


Any suggestions on how to solve these problems, potential causes, or stories of this being:
a) common
b) the exception to normal Prius
would be appreciated.
I'll take my car into the dealer on Monday. It is still under warranty. Thanks!
