Yesterday as I was backing out of the garage I noticed a small "grinding" noise coming from the front brakes. Not loud and obnoxious but definitely something that I had not heard before. I checked the EVIC and it showed the last chime as ABS. Since my wife was out of work yesterday we immediately took it to the dealership and dropped it off. The car is still there as of this morning, as I assume they did not look at it yet, which they did tell me upfront it may not be ready till Monday, no big deal. My question is, does anyone know what may be causing this, rotors, pads, etc? The car only has 2890 miles on it.
