2014 Chevrolet Malibu Electronic Stability Control Esc Problems

AS SOON AS CAR IS TURNED ON, A/C WILL NOT BLOW WHEN I TURN THE KNOB AND NO MATTER WHAT BUTTONS I PUSH. NOT SURE WHY IT DECIDES TO DO THIS SOMETIMES BUT NOT EVERY TIME. I HAVE SEEN THIS AS AN OFFICIAL RECALL, BUT IT SAYS MY VIN SHOULDN'T BE EFFECTED. THIS IS A RECURRING ISSUE THAT HAPPENS AT RANDOM. *TR

WHILE DRIVING APPX 70 MPH ON THE FREEWAY A "SERVICE STABILTRACK, REDUCED ENGINE PERFORMANCE" MESSAGE CAME ON. IMMEDIATELY THE CAR BEGAN A RAPID DECELERATION UNTIL IT CAME TO A COMPLETE STOP. LUCKILY WE WERE BARELY ABLE TO SAFELY MOVE ACROSS 3 LANES OF 70 MPH TRAFFIC & ONTO THE SHOULDER WHERE WE BECAME STRANDED. AFTER WAITING ABOUT 10 MIN WE WERE ABLE TO START THE CAR AND SLOWLY MAKE IT ABOUT A MILE TO A FREEWAY EXIT WHERE THE SAME EVENT REPEATED ITSELF EXCEPT THIS TIME THE CAR WOULD NOT RESTART. THIS IS THE 2ND TIME WE HAVE EXPERIENCED THE SAME PROBLEM. A CHEVY DEALER HAD CLAIMED TO FIX THE PROBLEM ABOUT 3 WEEKS AGO. WE HAVE BEEN VERY FORTUNATE TO AVOID AN ACCIDENT AS THE SITUATION WAS SIMILAR TO SLAMMING ON THE BRAKES IN THE MIDDLE OF THE FREEWAY AND BOTH OCCURRENCES RESULTED IN US BEING AT A DEAD STOP IN THE MIDDLE OF A ROAD NEEDING TO PUSH THE VEHICLE TO SAFETY.
