NHTSA Complaint #10818057 — 2013 CHEVROLET MALIBU

IN SUMMER 2015 WHILE USING AC, HEAT RANDOMLY WOULD BLAST OUT. (WHILE IDLE OR DRIVING). WOULD HAVE TO RESTART CAR TO GET AC TO WORK AGAIN. IN THE PAST 2 WEEKS DEC15/JAN16, ENGINE OVERHEATED-IDLE INDICATOR CAME ON WHILE DRIVING ON THE HIGHWAY, ONCE AT 65 MPH, ONCE AT 30 MPH. THEN A FEW MINUTES LATER IT WOULD TURN OFF. I LOOKED AT TEMP GAUGE, AND IT WAS NOT AT AN OVERHEATING LEVEL (HALF WAY ONLY). ALSO, NOW HEAT ONLY INTERMITTENTLY WORKS. I WILL HAVE TO TURN CAR ON AND OFF REPEATEDLY, AND TURN AC ON/OFF, HEAT ON/OFF, DEFROST ON/OFF, AND SOMETIMES THE HEAT WILL FINALLY GET WARM. NEVER SEEMS TO GET HOT LIKE IT'S SUPPOSED TO. TOOK TO REPAIR SHOP FOR THE ENGINE OVERHEATED/IDLE WARNING AND STATED NOTHING WAS WRONG. SAFETY ISSUE NOT HAVING HEAT FOR FRONT WINDSHIELD DEFROST WHEN IT'S UNDER 30 DEGREES OUT. MECHANIC SAID IT'S PROBABLY A COMPUTER ISSUE WITH THE CAR. BUT NOW I'M SEEING THIS IS A RECURRING PROBLEM WITH MANY CAR OWNERS. GM NEEDS TO RECALL, AS THIS CAN BE A SAFETY CONCERN!
