OVER THE PAST FOUR MONTHS MY 2012 YUKON HAS BEEN HESITATING / STOPPING. I HAVE ACCELERATE INTO IN THE INTERSECTION AND VEHICLE HESITATED ALMOST CAUSING AN ACCIDENT. THE CHECK ENGINE LIGHT HAS CAME ON AND OFF NUMEROUS TIMES, FLASHING STABILIZATION AND TRACTION SWITCHING ON AND OFF. I HAVE TAKEN IT TO THE DEALERSHIP AT LEAST FIVE TIMES EACH TIME THEY SAID THERE WAS NOTHING WRONG WITH MY VEHICLE SECOND TO THE LAST TIME THEY STATED I NEEDED A NEW FUEL PUMP WHICH THEY REPLACED AND THE PROBLEM CONTINUED WITH IN TWO DAYS AND CONTINUES TO THIS DAY . THE LAST TIME I TOOK IT IN THEY STATED THERE IS AN ISSUE WITH GM VEHICLES FROM 2013 TO 2017 CAUSING STALLING HESITATION LACK OF PERFORMANCE IN A SETTING IN HIGH AMBIENT TEMPERATURES AND THERE IS NO FIX FOR IT . I BELIEVE THIS IS A GREAT SAFETY RISK FOR INDIVIDUALS WHO LIVE IN HIGH CLIMATE AREAS .
