For the past week or so at random times I have been hearing this random grinding noise. The nest way to describe it is something like a blender chewing up ice cubes. It seems to only do it at low speeds however. I have no clue what it is. I searched and saw some IWE problems, but that was ont he 04-08 models. Any advice would help!

 

As far as I know, you have the same IWE system.

 

Any way to check and see if thats what is wrong with mine, besides going to the dealership and getting charged out the rear end?
