Lexus LS 2007+ :: Brake Lights Come On When Stepping On The Brake

I have a 2010 Lexus LS460-L. It is a nightmare. I can drive it 100 miles or sometimes 800 miles, and then when I am stepping on the brake, all the brake lights come on and the brakes catch and release like a wave motion at speeds under 15 mph until the computer gets reset by the service department, and it is good for another 4-6 weeks, when it reoccurs.

I have had it in to Toyota 5 times. Computer diagnostics fails to find the problem. I have paid to replace the master brake control module (ECU) and the stroke sensor. I had it in to the Lexus dealer in Kansas City, and they said that their diagnostics failed to find the problem, and the "only thing they could think of" is to replace the wiring harness and of course they don't recommend spending that much money on it. I was skeptical, so I took it to the same dealer's other location, and the service man there told me that their diagnostic tests are "pointing to the wiring harness".
