It was a recall for all models, but obviously it's not affecting you if you have it off and still have the issue.

I'm not necessarily recommending any of these, but here are some examples:

Yes, it's here: http://www.cars101.com/recalls.html

Customer complaint of radio static when the radio and rear window defogger are on at the same time, there is the possibility of a break in one or more of the defogger grids. When the grid is broken, a high resistance field is created at the break point which can create static on some radio stations. The level of resistance is usually high enough to create a field of interference which projects out from the glass. The break can be detected visually or by using a portable radio.
Using a portable radio, set the radio to the same frequency and station being disturbed by static. From the outside of the vehicle, slowly move the radio’s antenna across the defogger grids. When interference is encountered, inspect that specific area closely for a break. Depending upon the size of the break, a magnifying glass and/or eyeloupe may be required.
Once the break is identified, it should be repaired using the Permatex® repair kit instead of replacing the rear glass. Note: Make sure to carefully read and follow the instructions
and precautions that are included with the Permatex® repair kit.
Permatex® Quick Grid™ Rear Window Defogger Repair Kit, part # 15067, used for repairing damaged rear window defogger grids, is available at local automotive parts stores.
