2012 CADILLAC ESCALADE ESV Engine Problems

DRIVING NORMAL ON A CITY STREET FOR ABOUT ONE HOUR WITHOUT ANY WARNING THE VEHICLE STARTED ACTING STRANGE, THE DOORS LOCKED AND UNLOCKED, THE AC& HTG CAME ON, HTG&FAN FOR THE SEATS CAME ON, CLOCK BLINKED, NAVIGATION SCREEN BLINKED ON AND OFF, THE VEHICLE SOUNDED AS THOUGH IT WOULD ACCELERATE AND THEN HESITATE, IT DID THIS AT LEAST 4 TIMES, I NOTICED UPON BRAKING EACH TIME AFTER THE STRANGE OCCURRENCES THE VEHICLE APPEARED TO RUN OKAY, BUT ONLY WHILE BREAKING. AFTER THIS OCCURRED FOR ABOUT ONE MILE, THE STRANGE OCCURRENCES STOPPED AND THE VEHICLE DROVE AS SHOULD, OR AT LEAST IT SEEMED OKAY. AFTER READING SOME OF THE BLOG'S OF OTHER 2012 ESCALADE OWNERS HAVING THE SAME PROBLEM, GM SHOULD TAKE NOTICE, AFTER ALL THE VEHICLES ARE NOT CHEAP AND GM SHOULD CORRECT IT.
