NHTSA Complaint #10897884 — 2014 CHEVROLET SPARK

THE CHECK ENGINE LIGHT STARTS FLASHING AND THE TRACTION LIGHT COMES ON, THEN THE CAR LOSES ITS ABILITY TO ACCELERATE PROPERLY AND SHAKES ALL OVER LIKE IT'S ABOUT TO FALL APART. THIS IS PARTICULARLY DANGEROUS WHEN I'M ON THE HIGHWAY AND THE CAR SUDDENLY FORCES ITSELF TO GO SLOWER AND WON'T ACCELERATE BEYOND 20-30 MPH IF I'M FULLY REVVING THE ENGINE. IT IS AN UNPREDICTABLE ON AND OFF ISSUE THAT THE DEALERSHIP HAS YET TO SEE AND IS NOT RELATED TO TEMPERATURE AS THE ISSUE HAS OCCURRED IN ALL 4 SEASONS. AS OF LAST WEEK, THE ACCELERATION AND SHAKING ISSUES HAVE STARTED OCCURRING WITHOUT THE CHECK ENGINE OR TRACTION LIGHTS TO WARN ME IT'S HAPPENING AGAIN.
