Brakes Failed problems of the 2002 Honda Accord

This is the 3rd brake failure (2 partial/1 complete) that we have had with this vehicle,all of which have been reported to the dealership(technicians, management and owner), american Honda, and NHTSA. On 4/22/02, odometer 498/traveling 25mph/dry pavement/smooth road, the abs and tcs warning indicator lights came on and remained on. I immediately pushed the brake pedal which had softened to a little less than half before engaging. Frightened, I pulled over using my emergency brake to safely stop the vehicle. After stopping, I placed the vehicle in park and pumped the brake several times in an attempt to get the brake pedal to re-engage properly. It did not and both warning light indicators remained on. Because I was 1 block from the house and there were no other vehicles on the road, I decided to coast home at 5mph using the emergency brake. At my house, I placed the vehicle in park, left emergency brake engaged and turned off the vehicle. I immediately called the dealership with a detailed description and a tow truck was dispatched. It was determined to be a disconnected left abs sensor. I do not believe this is accurate nor is it consistent with the braking (and electrical) issues that we have experienced and previous repair attempts made by the dealership. I refused to pick up the vehicle on the grounds of this safety defect and the dealerships inability to accurately diagnose it. The vehicle was taken back by the dealership and we were placed in another new Accord. I aggressively stated to peter heuy, his sales manager, service manager, and technician and american Honda, that this vehicle contains a major safety defect in its brake system that an engineer from american Honda needs to isolate before placing the vehicle back on the road. Anything less than that is gross negligence. The dealership indicated this would not be done and the vehicle would be used as a demo.
