NHTSA Complaint #11234154 — 2015 GMC TERRAIN

VEHICLE PURCHASE FROM COULTER CADILLAC TEMPE AZ - 9/1/2018. THIS PROBLEM HAS OCCURED 3 TIMES. DEALER ACKNOWLEDGES "WE PUT YOU IN A BAD CAR". PROBLEM: VEHICLE WHILE IN MOTION (STREET/INTERSECTION/HIGHWAY), WILL JUST "SHUT DOWN" AND MOVE IN "LIMP MODE" FASHION. THE ENGINE AND STABILITY LIGHTS WILL APPEAR ON THE DASHBOARD AND ON THE MOST RECENT EVENT, ALL THE GAUGES ON THE DASHBOARD SHUT DOWN. AFTER THE SHUT DOWN,1 & 2 GEARS ARE NO LONGER AVAILABLE. IN ORDER TO MOVE THE VEHICLE, THE VEHICLE NEEDS TO REACH A SPEED BETWEEN 20 / 30 MILES AN HOUR IN ORDER FOR THE 3RD GEAR TO ENGAGE. THE LAST TIME THIS SITUATION HAPPENED WAS ON THE FREEWAY @ 65 MPH. I WAS IN THE HOV LANE WITH MY 3.5 YEAR OLD GRANDSON AND MY WIFE. ALL THE TRAFFIC @ 4:45 PM ON THE NORTHBOUND LANE OF THE AZ 17 HIGHWAY CAME TO A STOP BECAUSE OF THE RIPPLING EFFECT THIS PROBLEM CAUSED. FORTUNATE FOR US, OTHER DRIVERS ALLOWED TO US TRAVERSE TO THE OFF RAMP. THE DEALER INDICATED THE PROBLEM WAS THE BATTERY THAT BROUGHT THE CAR TO A STOP AND "LIMP MODE". THERE WERE NO BATTERY WARNING LIGHTS VISIBLE ON THE DASHBOARD TELLING ME THE BATTERY WAS IN DANGER OF FAILING AS NOTED IN THE OWNER'S MANUAL. ALL 3 TIMES THIS HAS HAPPENED, THE DEALER HAS PROVIDED 3 DIFFERENT SOLUTIONS FOR THE SAME PROBLEM. I HAVE SEEN ON THIS WEB SITE NO LESS THAN 15 COMPLAINTS RAISING THIS PROBLEM TO THE NHTSA ATTENTION. SOMEONE IS GOING TO GET HURT BECAUSE OF THIS PROBLEM COULTER/GMC AND THE NHTSA NEED TO TAKE ACTION TO REMOVE/RESOLVE THIS PROBLEM. SEE ATTACHED EXHIBIT T / U / O.
