general problems of the 2007 Lexus LS460

I was driving home at 25mph (without my child) approaching an intersection, when the car in front of me makes a last minute lane change to turn at the intersection, I go to break and it doesn't break, the pedal reacts hard where it's always a soft compression, the dash lights up flashing the message "break malfunction" "check abs, check vsc, check brake system, not to drive vehicle due to system failure, contact deal immediately". I coast down the road and upon breaking again the whole car shakes making steering and especially turning very difficult. I take it 5mph the rest of the way and once home and parked, I try to restart the vehicle. When depressing the brake to activate the electric start, the break kicked back and the car would not start. I had the vehicle towed to the dealer it was purchased from. The dealer did confirm it was the break actuator assembly (l-sb-0178-09) that had been issued a special warranty (policy bulletin 16-01) with a 10 year term from purchase date. Unfortunately the issue had not been taken care of with the original owner and then became a problem 8 months after I made the purchase. . . Which is now out of the special warranty term. I am currently working to resolve the issue and hope Lexus will help cover the $2600 repair. More importantly I am hoping it becomes a recall because of the safety issue. I can't imagine what would of happened if I was on the freeway.
