NHTSA Complaint #11396561 — 2012 CHEVROLET VOLT

TEMPERATURE SENSORS RESPONSIBLE FOR MONITORING THE BATTERY PACK FAIL UNEXPECTEDLY. SOMETIMES DISPLAYING A "BATTERY TOO COLD PLUG INTO WARM" MESSAGE OR A CHECK ENGINE LIGHT. PERSONALLY, THIS IS THE SECOND TIME I'VE HAD A SENSOR FAIL. THE ENTIRE MODULE CONTAINING THE FAILED SENSOR MUST BE REPLACED. THE BATTERY IS MADE UP OF THREE DIFFERENT SECTIONS CALLED MODULES. WHEN A SENSOR FAILS, THE CAR WILL SIMPLY REFUSE TO START DESPITE BEING WITHIN A NORMAL OPERATING TEMPERATURE RANGE. I'VE HAD THE MESSAGE DISPLAY WHEN IN MOTION. THIS TIME HOWEVER, THE MESSAGE WAS ACCOMPANIED BY A CHECK ENGINE LIGHT, AND A BURNING ODOR THAT RESEMBLES BURNING PLASTIC WHILE THE ENGINE IS RUNNING. I HAVE YET TO EXPERIENCE REDUCED PROPULSION OF ANY KIND WHILE DRIVING.
