NHTSA Complaint #11311988 — 2015 CHEVROLET MALIBU

THIS HAS OCCURRED ON MORE THAN ONE OCCASION BUT MOST RECENTLY IT SCARED ME MOST BECAUSE I WAS IN THE MIDDLE OF A BUSY HIGHWAY ! AS THE CAR CAME TO A STOP IT WHEN INTO POWER SAVE MODE (AUTOMATIC SHUTOFF) HOWEVER ONCE TOOK MY FOOT OFF THE BRAKES IT DIDN'T NOT START THE CAR WENT COMPLETELY DEAD AT THE MIDDLE OFF A BUSY HIGHWAY . I TRIED REPEATEDLY TO CRANK BUT IT WOULD NOT START AFTER 3-5 MINS IT'S FINALLY CRANKED UP . NOW I'VE NOTICED THAT IF IN COMING TO A STOP I HAVE TO KEEP THE CAR FROM GOING INTO AUTO SHUTOFF MODE BY LETTING OFF THE BRAKE A LITTLE BEFORE IT ACTUALLY COMES TO A COMPLETE STOP .ALSO I WAS AT THE DRIVE THRU WINDOW OF A RESTAURANT WHEN IT SHUT OFF ON ME THE LAST TIME IT FINALLY GAVE A "SERVICE STABILIZER" MESSAGE LUCKILY I HAD A PORTABLE BOOSTER IN THE TRUNK AND JUST CONNECTED IT TO THE BATTERY AND THE CAR CRANKED RIGHT UP . SO FOR MY SAFETY AND MY CHILDREN'S SAFETY I KEEP THE PORTABLE BOOSTER IN THE TRUNK BECAUSE IDK WHEN IT'LL JUST CUT OFF . ALSO I HAVE USE MY WARRANTY TO HAVE THE CAR SERVICED HOWEVER AFTER GETTING BEATEN OUT OF SO MUCH MONEY FOR DIAGNOSTICS AND BEING TOLD THEY CAN'T FIND ANYTHING WRONG WITH THE VEHICLE IDK WHAT ELSE TO DO .IT DOES NOT HAPPEN EVERYDAY BUT IT'S BEGINNING TO HAPPEN MORE FREQUENTLY NOW. ALSO WHEN I PUT THE CAR IN REVERSE IT TAKES A FEW SECONDS FOR THE BACKUP CAMERA TO COME ON .I NOTICED BEFORE I HAD THE MAJOR PROBLEM WITH IT SHUTTING DOWN COMPLETELY A COUPLES TIMES WHEN I WOULD PUT THE CAR IN REVERSE THE RADIO /SCREEN WOULD GO COMPLETELY BLACK AND ONCE I PUT IT BACK INTO DIVE THEN IT WOULD COME BACK ON
