NHTSA Complaint #11364455 — 2017 CHEVROLET VOLT

UPON STARTING THE CAR (AFTER SITTING IN THE SUN WITH WINDOWS UP, SO HOT CABIN), WHEN I SHIFT TO ANY GEAR OUT OF PARK, I GET AN ACTION REQUIRED SHIFT TO PARK MESSAGE. THE SHIFTER WILL GO TO DRIVE, FOR EXAMPLE, BUT PRESSING THE GAS PEDAL DOES NOT MOVE THE CAR, AND I HAVE THE MESSAGE TO SHIFT TO PARK. THIS HAS HAPPENED TWICE. BOTH TIMES I ROLLED DOWN WINDOWS, AND TRIED TURNING THE CAR OFF AND BACK ON AGAIN TO RESOLVE THIS. AFTER SEVERAL ROUNDS OF THIS, THE CAR DID SHIFT TO DRIVE AND WOULD GO. HOWEVER THE ENGINE IS RUNNING (RATHER THAN ONLY ELECTRIC, AS I USUALLY OPERATE); THE BATTERY GAGE IN CLASSICAL MODE SHOWS A RAPIDLY DECREASING CHARGE, THEN INCREASING, THEN DECREASING - ALSO THE PLACE WHERE IT SHOWS HOW MANY MILES LEFT IN BATTERY IS GREYED OUT AT 0, EVEN THOUGH THE BATTERY MAY APPEAR TO BE CHARGED MORE THAN HALF. ALSO, WHEN TRYING TO SHIFT MODES, HOLD MODE IS GRAYED OUT AND I CANNOT ACTIVATE IT. ONCE I ARRIVE AT MY DESTINATION AND TURN THE CAR OFF, PLUG IT IN, NEXT TIME IT TURNS ON AS NORMAL. CHECK ENGINE LIGHT IS ON FOR ALL THIS, AND DOES NOT TURN OFF WHEN RESTARTING A FULLY CHARGED BATTERY THE NEXT DAY.
