2006 Toyota Sequoia cruise control problems

Toyota sequoia (ball joints recall) was driving on highway I-5 northbound just after the bridge that goes over the sacramento river I was on the bypass/cosway bridge driving in the #1 (of 2) lane going 65 MPH when suddenly my front end driver's side of my vehicle dropped completely and I was skidding on complete metal, I had no breaks and continued to skid for what seemed like forever, and steered to my to my right passing the #2 lane going up against the edge of the right side on the bridge.

While driving at low speeds the vehicle experienced a momentary loss of power and a grinding/vibrating of the brakes while in motion. The trac off and vsc trac warning lights came on along with the brake light. The warning lights and vibrating of the brakes could only be reset by turning the ignition off and restarting the vehicle. It happened twice in the last 12 hours.
