Wow, are you sure there isn't a Chrysler logo on that somewhere! Definitely sounds like a new Chrysler product.
The chattering with the shifting does seem normal. The fiesta I drove did it and it sounds like a manual transmission shifting.
The other stuff ... not really sure. Sorry to hear about your bad luck with the car :(
