Brake Electric Antilock problems of the 2008 Subaru Tribeca

I was driving 70 mph on the right most northbound lane of I-75 at mile marker 452 in florida. The road had become wet from recent rain. The rear of my car suddenly started fishtailing to the right. The fishtail evolved into full-blown counterclockwise spins which took the car all the way to the guardrail in the middle shoulder. The impact resulted in the car being totaled. I believe a defect with the abs, electronic stability control system or the all wheel drive caused the accident. The road was perfectly straight, and I didn't apply the brakes or make any sudden steering changes. I reported the incident to Subaru and asked for an investigation of the wrecked car. Despite three letters and a complete report, the company refused to inspect the car.
