NHTSA Complaint #11153931 — 2015 GMC SIERRA 1500

WHEN I PRESS ON THE BRAKES, IT FEELS AS THOUGH THE MASTER CYLINDER IS GONE AND IT IS THE MANUAL TYPE DRUM BRAKES THAT HAS AIR IN THE LINE. IT TAKES EVERYTHING I HAVE TO PRESS THEM AND PRAY IT STOPS!! THE VEHICLE IS ALWAYS IN MOTION WHEN DETECTING THIS PROBLEM AND SEEMS TO OCCUR MORE REPEATEDLY IF THE BRAKES ARE PUMP QUICKLY IN SUCCESSION BEFORE APPLYING BRAKES OR WHEN THE BRAKES ARE PRESSED FOR AN EXTENDED AMOUNT OF TIME THEN YOU RELEASE AND REPRESS IT WANT STOP. ANOTHER ISSUE IS MY LANE ID WARNING. WHEN TURNED ON AT THE BUTTON, IT JUST BEEPS AT ME AND SHOWS SERVICE LIGHT. WHEN I FIRST TOOK IT IN WITH THE PROBLEM, THE DEALERSHIP CALLED ME AND SAID ALL FIXED, BUT IT DID IT BEFORE I LEFT THE PARKING LOT. THEY HAD MY TRUCK ALL DAY FOR THE ISSUE, PUT ME OUT OF A VEHICLE AND THEN SAID THEY WOULD NEED FOR EXTENDED TIME TO REPAIR BUT DIDN'T KNOW THERE WAS PROBLEM. HOW DO YOU MAKE THAT DETERMINATION WHEN YOU TOLD ME ITS REPAIRED. I JUST TURNED IT OFF AND HAVEN'T USED IN 2 YEARS.
