2015 CHEVY TAHOE, WE PURCHASED TWO MONTHS AGO STILL UNDER FACTORY WARRANTY. I WAS TURNING AROUND IN THE DRIVEWAY, HIT THE BRAKES, AND THE BRAKE PEDAL WOULDN'T MOVE. IT WAS EXTREMELY STIFF, CAUSING ME TO CRASH THE VEHICLE INTO MY UTILITY TRAILER. I PUSHED AS HARD AS POSSIBLE AND NOTHING HAPPENED. THERE WAS ALMOST NO BRAKING PRESSURE AT ALL AND MY SUV JUST KEPT GOING. I PURCHASED THIS VEHICLE FOR MY FAMILY BUT NOW EVERYONE IS SCARED TO RIDE IN IT. I'VE FINANCED A VEHICLE FOR YEARS THAT I'VE HAD POSESSION OF FOR MONTHS, AND IT'S MOST NESSCERY SAFTEY FUNCTION HAS FAILED. I'M EXTREMELY DISAPPOINTED. I'VE ALWAYS OWNED GM VEHICLES. AS A 31 YEAR OLD FATHER OF 3 SMALL CHILDREN, THIS WAS A VERY LARGE PURCHASE FOR OUR YOUNG FAMILY. NOW I FEEL I MAY HAVE TO LOOK OUTSIDE MY TRUSTED BRAND TO FIND A SAFE VEHICLE I CAN TRANSPORT THE MOST PRECIOUS CARGO IN. IT'S VERY DISAPPOINTING . I THEN FIND OUT THIS EXACT ISSUE HAS CAUSED MULTIPLE CRASHES INVOLVING INJURIES. GM IS AWARE THIS IS A PROBLEM, LAWSUITS HAVE BEEN FILED, YET LITTLE OR NOTHING HAS BEEN DONE. HOW CAN GENERAL MOTORS KNOWINGLY TURN A BLIND EYE AND ALLOW THIS LIFE THREATING SAFTEY ISSUE TO GO ON IN A VEHICLE MARKETED TO FAMILIES?
