2016 CHEVROLET TAHOE Forward Collision Avoidance Automatic Emergency Braking Problems

-MALFUNCTION---WHILE DRIVING, WHEN I PRESS THE BRAKES TO COME TO A STOP, IT SEEMS AS IF THE BRAKES CATCH BUT THEN RELEASES AND THEN CATCHES AGAIN. AS IT RELEASES, IT CONTINUES TO ROLL. VEHICLE IS AVAILABE UPON REQUEST. -SAFETY RISK--- BECAUSE THE BRAKE RELEASES AND/OR EVENTUALLY NOT CATCH AT ALL, THIS IS UNSAFE BECAUSE I CAN ROLL INTO TRAFFIC -REPRODUCED AND/OR CONFIRMED--- I HAVE BROUGHT MY VEHICLE TO A SERVICE CENTER TO REPAIR A RECALL AND WAS TOLD TO THAT THE ISSUE SHOULD BE RESOLVED ONCE THE RECALL WAS COMPLETE. THE ISSUE WAS TEMPORARILY RESOLVED FOR APPROXIMATELY ONE MONTH OR SO, AND NOW IT IS BACK TO BREAKING AND RELEASING. -ONE CAN ONLY ASSUME THAT THE VEHICLE AND/OR ITS COMPONENTS HAVE BEEN INSPECTED GIVEN THAT I BROUGHT THE VEHICLE TO THE SERVICE CENTER, STATED THE ISSUE, AND WAS TOLD THAT THE ISSUE SHOULD BE RESOLVED AFTER IT HAS BEEN SERVICED....

I was driving down highway and saw a wall of cars and brake lights in the distance, so naturally my foot tried to push the brakes. The pedal was hard, and I panicked because my tahoe was not stopping at all! I continued to stomp on brake pedal all the way until my car actually hit 3 vehicles and then the guardrail! My brakes did not work , because if they did then I would have easily prevented this accident!!

ITS SEEMS THAT THE ABS COMPUTER STOPPED WORKING AND THE BREAK AND TRACTION CONTROL ASSIST ALSO.
