Brake Light On problems of the 2005 Toyota Tacoma

It was clear and dry on the day of the accident. The hov lane was dry and newly paved. I was traveling approximately 65-60 mpg when I saw brake lights. I began to decelerate and step on the brakes at about 300 feet. Suddenly, I noticed that the vehicle in front of me was not stopping, but rather that it had already stopped! at approximately 200 feet away from the car, I pressed my brake petal to the floor. At 20 feet behind him, I said to myself that my vehicle had enough room to stop before hitting him. But something happened at this point. It felt like someone was pushing my vehicle from the back (it was not being pushed), or the vehicle accelerated, or that the abs system released the pressure on the brakes. The result was that I rear-ended the vehicle. Although our airbags deployed, neither I nor my passenger had contact with the airbags. I was probably going less than 15 mph at impact. When braking, I never felt the tattle-tell feeling of a pulsating brake pedal when the abs system goes into effect. I have had problems with the abs system in the past when driving in 4-wheel drive in snow and driving off road. The abs system would take the braking control away from me, which has caused some problems. This happened in 2009 (off road) and 2010 in deep snow. I took the vehicle to the dealership to examine my braking and abs system. They could not find any problems. If the abs is at fault, this would be the first time since 2010 and the first time on dry road. The specifications for my vehicle say that it only takes 126 feet to make a stop. The vehicle was totaled and sold by the insurance company. They will hold it for only 4 days for investigation. The vehicle was recalled and serviced for similar problems in the past. I contacted the Toyota regional office on 02/27/2014, but they will not do an investigation.
