NHTSA Complaint #11404252 — 2017 CADILLAC XT5

I HAVE HAD THE VEHICLE, WHICH IS STILL UNDER FACTORY WARRANTY, FOR 5 MONTHS. THE VEHICLE BEGAN ALARMING ON THE FIRST DAY I DROVE IT (10/16/20). MONDAY, 10/19/20, THE VEHICLE WENT INTO "PARK" WHILE I WAS DRIVING IT. THE DEALERSHIP DID A QUICK ASSESSMENT AND CALLED BACK AND TOLD ME THE BATTERY WAS THE CAUSE OF THE ISSUE. MY IMMEDIATE QUESTIONS WERE "WHY DIDN'T THE BATTERY INDICATOR APPEAR?" AND "WHY WOULD A LOW BATTERY CAUSE THE SUV TO GO INTO PARK WHILE I WAS DRIVING IT?" HOWEVER, AS THEY WERE RETURNING THE SUV TO ME, THE TRANSMISSION LIGHT CAME ON. THE TRANSMISSION ELECTRIC CONTROL WAS REPLACED DUE TO "AN INTERNAL FAILURE IN SHIFTER" THAT WAS UNDETECTABLE. ON 12/21/20, THE SAME DEALERSHIP REPLACED THE WATER OULET BECAUSE THEY FOUND A LEAK "COMING FROM BETWEEN THE THERMOSTAT HOUSING AND WATER OUTLET PIPE". ON 3/14/20, AFTER DRIVING THE VEHICLE 175 MILES AT 75MPH, THE VEHICLE SUDDENLY DECELERATED. THE VEHICLE WAS NOT RESPONDING TO ME PRESSING ON THE GAS PEDAL. NO WARNING LIGHTS SHOWED AND NO ALARMS SOUNDED. ADDITIONALLY, ONCE THE VEHICLE WAS STOPPED, IT WOULD NOT RESTART. ONSTAR RAN A DIAGNOSTIC REPORT AND NO CODES WERE FOUND. THE THERMOSTAT HAD A NORMAL READING. THE ONSTAR REPRESENTATIVE RECOMMENDED THAT I ALLOW THE VEHICLE TIME TO COOL AND THEN RESTART THE VEHICLE. I DROVE BACK HOME WHILE MAKING FREQUENT STOPS TO ALLOW THE VEHICLE TIME TO COOL OFF. ON 3/15/20, I RETURNED THE VEHICLE TO THE DEALERSHIP. ON 3/22/20, THE DEALERSHIP NOTIFIED ME THAT THEY COULD NOT REPLICATE THE PROBLEM AND DID NOT FIND ANY PROBLEMS DURING THEIR DIAGNOSTIC EVALUATION. THEY ALSO DID NOT TEST THE VEHICLE BY DRIVING IT EITHER. I WAS TOLD ME TO COME PICK UP THE VEHICLE WITHOUT KNOWING THE REASON THAT THE SUV CUT OFF WHILE DRIVING IT ON THE HIGHWAY. THE 2017 CADILLAC XT5 IS UNSAFE AND COULD RESULT IN AN ACCIDENT OR DEATH. PLEASE INVESTIGATE THIS VEHICLE.
