2017 Chevrolet Tahoe Brakes

HARD BRAKE PEDAL RESULTING IN LITTLE OR NO STOPPING POWER WHEN APPLYING THE BRAKES AT LOW SPEED. TO GET THE VEHICLE TO STOP, YOU MUST STOMP ON THE PEDAL AS HARD AS YOU CAN. THE SITUATION TYPICALLY OCCURS WHEN PARKING. THE BRAKE APPLICATION OR TWO ARE FINE, BUT AFTER THAT THE BRAKES FAIL. THIS SAME ISSUE APPEARS TO BE WELL DOCUMENTED UNDER NHTSA ID NUMBER 10081053 AND GM PIT5361B, HOWEVER THOSE DO NOT INCLUDE THE 2017 MODEL YEAR, AND I AM SEEING WHAT APPEARS TO BE THE EXACT SAME ISSUE ON MY 2017 TAHOE.

DRIVING IN TRAFFIC SLOW SPEED, BRAKES WENT TO FLOOR, LOST POWER BRAKES, POSSIBLY VACUUM PRESSURE. VERY HARD TO STOP VEHICLE. BRAKES WORKED AFTER DRIVING AT A HIGHER SPEED WHILE ATTEMPTING TO EXIT THE ROAD. THIS IS A BRAKE BOOSTER/VACUUM LOSS ISSUE IN MY OPINION. THIS IS A 1 YEAR OLD VEHICLE. THIS SHOULD NOT BE HAPPENING. I HAVE VIDEO OF THIS HAPPENING.
