noise

Is been about 1K miles with my Touring, so far loving it... Only concern I started hearing random "plastic rubbing noises" I can't detect what it is but is coming from the back of the car. I notice it more when on a sunny day. Not sure if others have experience such and if so, did you ever find...

This is new, it started to happen after my last service. Not sure it's related to the service or the car started to lose up in general. My air is at 15,181 miles as of today. The creaking noise is similar to the steering wheel creaking noise. I'm not 100% sure it's coming from the passenger door...

Has anyone noted the sounds the car makes when in reverse. There are a few background noises in the interior, in my car I hear a chirp like noise in the exterior when backing up (and have no idea if this is normal).
