Starter Solenoid Problems of Toyota Prius

I have reviewed my service records and it is quite clear that I have had problems with the "electrical" system in my car since April 2006 @ 3,370 miles. This was also the same time it began to accelerate from a stopped position for the first time, when I noticed that the braking system began to "feel" different, when the car began "slipping" on perfectly dry roads, and when my steering wheel would lock up. I find it difficult to believe that the failure of my brakes and my intermittent acceleration issues are not somehow related to the cars "computer" system and not mechanical issues. I have filed complaints with Toyota for these issues (cases # 200807100210, 200811030088). I experienced my first braking issue on 27-Jun-2008 (25,133 miles). While I was able to bring the car to a stop eventually, the slowing of my car was a very gradual process requiring heavy pressure on the brake with minimal braking response. I went to the Toyota dealership. The dtc code at the time was c1247 with "code 179" stored, there was "no brake assist. " the dealership reset the memory and reinitialized the linear solenoid valve and calibration. The brakes were reported to have returned to "normal. " on 09-Jul-2008 (25,551 miles), I returned to the dealership because my brakes failed again. This time my brake failure resulted in a car accident (the person I hit stated at the time of the accident he had whiplash but he never contacted me afterwards). Toyota replaced the skid control ecu and rechecked operation reassuring me once again that the brakes had returned to "normal. " on 03-Nov-2008 (29,575 miles) as I was driving over 65 on a major highway my brakes again failed (dtc c1247, code 179). Toyota case #08300402. At this point the repair shop replaced the brake stroke sensor. I am concerned because my car had an acceleration issue on 13-Feb-2010 and I find it to be "slipping" again on dry roads. Similar problems to those I had before my brakes failed. Please help. Updated ivoq 04/02/10 updated 04/08/10.
