2008 Pontiac Solstice brakes problems

I purchased my 2008 pontiac solstice on september 29, 2009. I didn't have a problem until I started it up and began to pull out of the nearby mall parking lot and as I went to press the brake, it made a low grinding noise, almost like the ABS was locking up except the light wasn't on, and I was merely cruising, not even on the gas pedal. I rear ended the person in front of me - not bad, just knocking off my pontiac emblem on the hood, and denting it in slightly. The very next day, the same incident occurred.

Tl*the contact owns a 2008 pontiac solstice. While driving 3-5 MPH, the contact heard a grinding noise when the brake pedal was depressed. He had to shift into neutral in order to stop the vehicle. The dealer stated that there was a service bulletin for the failure, in which the manufacturer recommends not to repair the vehicle. As of november 20, 2007, the dealer had not repaired the vehicle. The failure mileage was 20 and current mileage was 550.
