My 2003 Buick Park Avenue with less than 6000 miles on it has had brake failure twice. Both incidents occured at speeds less than 10 mph. Both incidents involved total brake failure with the pedal going clear to the floor and no stopping action at all. The first incident in August 2003 resulted in a crash in which there was no fire and no injuries. The most recent incident reported today did not result in a crash but could have easily had I not thrown the transmission into park. Dealer reports he "can not duplicate the problem", and doesn't know what to fix. Ongoing negotiations continue between me and the dealer as I feel the car is definitely unsafe as is, and if there is "nothing to fix", then obviously the car will remain unsafe and could result in serious injury or fatalities not only to myself but to others. I strongly urge NHTSA get involved before any lives or lost or serious injuries occur.
