NHTSA Complaint #11246669 — 2012 CHEVROLET VOLT

THE CAR WILL SHUT ITSELF OFF WITH VERY LITTLE TIME TO GET TO THE SIDE OF THE ROAD IF THAT IS EVEN A POSSIBILITY. WHEN SWITCHING FROM BATTERY POWER TO THE GAS MOTOR. RANDOMLY. THE CAR WILL DIE AT ANY SPEED. FIRST MESSAGE IS LOW PROPULSION POWER. NEXT MESSAGE ENGINE NOT AVAILABLE, SERVICE SOON. LESS THAN 4 MINUTES FROM 1ST MESSAGE TO TOTAL SHUT DOWN. LEAST AMOUNT OF TIME BETWEEN MESSAGES AND SHUT DOWN IS 15 SECONDS. CAR WILL DECELERATE (ON HIGHWAY WHERE VEHICLES BEHIND HAVE NO WARNING... NO BRAKE LIGHTS THAT CAR IS RAPIDLY LOSING SPEED). NEVER KNOW WHEN IT WILL HAPPEN. USUALLY CAR WILL RESTART AND RUN TERRIBLE.. AFTER 20 MINUTES OR SO. AFTER RESTART CAR RUNS BAD LOW POWER. CHECK ENGINE LIGHT IS ON. AFTER 10 MORE MINUTES OF DRIVING. IT STRAIGHTENS OUT. USUALLY. DEALERSHIP UNABLE TO FIND PROBLEM. ASSORTED CODES IN COMPUTER. VERY DANGEROUS WHEN DRIVING. ESPECIALLY WHEN IT HAPPENS AND IT IS 15 SECONDS TO COMPLETE SHUT DOWN. I HAVE OPENED A CASE WITH CHEVROLET. NO RESPONSE AS OF YET. THEY WERE SUPPOSED TO CALL WITHIN 2 DAYS. I WILL UPLOAD AN ATTEMPT AT RESTART AS IT IS THE ONLY ONE I HAVE WHERE I WAS SAFELY IN A PARKING LOT WHEN IT HAPPENED. USUALLY I AM NOT. AND MANY ROADS IN MY AREA DO NOT HAVE A SHOULDER.
