PURCHASED VEHICLE USED IN MAY 2015, MY TRUSTED MECHANIC CHECKED IT OUT SEPTEMBER 2015 AND REPORTED BACK IT WAS IN GOOD CONDITION WITH NO ISSUES. JULY 2016 EXPERIENCED BREAK FAILURE AT 15 MILES AN HOUR. AGAIN MY MECHANIC TROUBLESHOOTED THE ISSUES AND SAID THE POWER BREAK BOOSTER NEEDED TO BE REPLACED. HE THEN REFERRED ME TO NISSAN FOR POSSIBLE REPLACEMENT SINCE IT IS A SAFETY ISSUE. I SPOKE WITH CORPORATE NISSAN WHO ADVISED ME TO TAKE IT TO OUR LOCAL NISSAN DEALERSHIP TO PROVE THE ISSUE EXISTED, FOR ANY POTENTIAL COMPENSATION. AFTER TAKING THE VEHICLE TO NISSAN THEY CONCLUDED REPROGRAMMING THE DELTA STROKE SENSOR WOULD RESOLVE THE PROBLEM; WHICH I HAD TO PAY $300 TO HAVE THIS DONE. ON OCTOBER 2016 INOPERABLE BREAK FAILURE OCCURRED AGAIN AT 65 MILES AN HOUR WHILE ON THE INTERSTATE, AS I WAS APPROACHING AN EXIT RAMP. THIS SAME ISSUE OCCURRED TWICE IN ONE DAY, JUST A WEEK LATER. ONCE AS I LEFT WORK GOING 40 MILES AN HOUR, MY DASHBOARD LIT UP WITH VDC AND SKID LIGHTS, IN ADDITION TO MY BREAK FAILURE LIGHT. THE SECOND TIME OCCURRED GOING DOWN A CITY STREET WHERE I HAD TO DO A ROLLING STOP THROUGH AN INTERSECTION, DODGING ONCOMING TRAFFIC, EVENTUALLY HITTING A CURB TO STOP. AFTER TAKING MY VEHICLE BACK TO NISSAN FOR THEM TO TEST DRIVE (RECREATE) THE PROBLEM, I WAS TOLD THAT I COULD NOT DRIVE MY VEHICLE OFF THE LOT DUE TO SAFETY HAZARDS. I HAVE SPENT HOURS ON THE PHONE WITH CORPORATE TO RESOLVE THIS SAFETY ISSUE; BUT YET NISSAN REFUSES TO FIX THE PROBLEM, OR REFUND ME MY MON
