NHTSA Complaint #11256804 — 2015 CHEVROLET SUBURBAN

I CONTINUE TO HAVE REOCCURRING PROBLEMS WITH MY 2015 CHEVY SUBURBAN. THE PROBLEMS CONSIST OF ELECTRONICS RESETTING/FLASHING OR TURNING OFF AND STAYING OFF, SPECIFICALLY, MEDIA SYSTEM, WINDOW CONTROL. MANY TIMES THIS OCCURS AT A SIMILAR TIME TO THE STABILITRACK WARNING SYSTEM COMING ON AND LOSING POWER STEERING AND COMPLETE LOSS OF POWER TO THE VEHICLE. SOMETIMES AFTER THE LOSS OF POWER THE VEHICLE WILL NOT CRANK WITHOUT BEING JUMPED OFF. THE VEHICLE WAS BROUGHT IN FOR SERVICE AT CAPTIOL CHEVROLET IN MONTGOMERY FOR THESE ISSUES ON 8/27/19-8/30/19. NO DIAGNOSTIC CODES WERE FOUND, HOWEVER, IT WAS RECOMMENDED WE SERVICE THE DIRTY THROTTLE BODY AS THIS COULD BE PART OF THE PROBLEM. WE HAD THIS SERVICE PERFORMED. SINCE THEN, WE'VE EXPERIENCED PROBLEMS ON 9/2/19 @ 4PM-ISH- ALL ELECTRONICS FLASHED OFF/ON WHILE TRAVELING DOWN INTERSTATE, FOLLOWED BY STABILITRACK WARNING AND LOSS OF POWER STEERING WHILE COMING TO STOP AT BOTTOM OF INTERSTATE OFF RAMP APPROX. 15 MIN. LATER. 9/12/19 @ 3:45 PM- STABILITRACK CAME ON 3X IN A ROW WITH LOSS OF ENGIN POWER, ALL ELECTRONICS WENT OFF, INCLUDING NO WINDOW CONTROL OR SCREEN, CAME BACK ON WHEN CRANKED BUT DELAY IN SCREEN COMING ON. 9/19/19 @ 3:08 PM-MEDIA SCREEN FLASHED AND RESET CLOCK TO 12:00. 9/19/19 @ 7PM- CAR DIED WHILE PARKING IN SAM'S WHOLESALE PARKING LOT AND HAD TO BE JUMPED OFF. CAR WILL NOT TURN OVER AT ALL UNTIL JUMPER CABLES ARE CONNECTED AND THEN IT TYPICALLY CRANKS RIGHT UP. NEW INTERSTATE BATTERY WAS PURCHASED 4/6/18. WHEN WE HAD PROBLEMS WITH VEHICLE LAST FALL THIS BATTERY WAS REPLACED WITH A NEW INTERSTATE BATTERY ON 11/3/18. WE HAVEN'T HAD PROBLEMS WITH CAR FROM THAT POINT UNTIL AUGUST 2019. IT DID SEEM TO HELP BUT I CAN'T AFFORD TO REPLACE THE CAR BATTERY EVERY 9 OR 10 MONTHS. CHEVY DOESN'T SEEM TO KNOW WHAT THE PROBLEM IS OR HOW TO FIX IT.
