NHTSA Complaint #11140264 — 2018 CHEVROLET VOLT

I WAS DRIVING MY CAR ON FREEWAY AT 65 MPH AND SUDDENLY CAR DISPLAYED WARNING ON DASH BOARD TO SHIFT THE CAR IN PARK POSITION. CAR IMMEDIATELY LOST POWER FROM ENGINE. I HAD TO IMMEDIATELY PULL OVER CAR FROM LEFT MOST LANE TO BUFFER LANE BETWEEN FREEWAY AND EXIT. MY MOVE UNTIL IT HAD MOMENTUM. BUT THEM IT STOPPED ON FREEWAY. AFTER STOPPING CAR, IT DID NOT START OR STOP ENGINE. IT DISPLAYED CHECK ENGINE LIGHT. WHILE RESTARTING CAR, IT KEEP DISPLAYING "INITIALIZING" AND IMMEDIATELY SYSTEM REBOOT BY ITSELF. CAR DID NOT START AT ALL AND EVENTUALLY CAR HAD TO BE TOWED TO DEALERSHIP. CHEVROLET DEALER COULD NOT IDENTIFY ROOT CAUSE AND REPORTED THE ISSUE IS FIXED. AFTER FIVE DAYS, EXACTLY SAME ERROR OCCURRED AGAIN ON THE FREEWAY. AT THIS TIME, WITH HELP FROM ONSTAR, MULTIPLE ERROR CODE WERE RETRIEVED AND THEY WERE RELATED TO FAILURE IN HYBRID POWER TRAIN SYSTEM. ABOVE TWO INCIDENTS WERE QUITE RISKIER AS CAR LOST ENGINE POWER ON BUSY FREEWAY. IT COULD HAVE SERIOUS COLLISION. ALSO, INCIDENT OCCUR ON ALMOST NEWLY LEASED CAR.
