NHTSA Complaint #11122469 — 2017 CHEVROLET SPARK

I WAS DRIVING ON THE FREEWAY UP A SLIGHT INCLINE, IT WAS OVER 100 DEGREES OUTSIDE, HAD AC WORKING AND HAD CRUISE CONTROL SET TO 70 MPH, THE CRUISE CONTROL SUDDENLY CANCELED ITSELF OUT AND MY SPEED RAPIDLY DROPPED. THIS ALWAYS SEEMS TO HAPPEN WHEN THE WEATHER IS OVER 100 DEGREES OUTSIDE AND GOING UP AN INCLINE, EVEN SLIGHTLY. ANOTHER PROBLEM I AM HAVING IS THAT WHEN I COME TO A STOP, SOMETIMES THE CAR SHUDDERS AND JERKS. ALSO IF I AM RUNNING THE AC ON THE VEHICLE IN PARK, SOMETIMES THE AC CUTS OUT ITSELF. IN ORDER TO START IT AGAIN I NEED TO TURN THE KNOB TO OFF AND TURN THE KNOB BACK ON TO GET AC WORKING AGAIN. THESE ISSUES ALL OCCURRED RANDOMLY, MULTIPLE TIMES
