NHTSA Complaint #10722269 — 2014 CHEVROLET TRAVERSE

I WAS DOING ABOUT 50 MPH ON EXPRESSWAY AND CAR STARTED TO SLOW DOWN WITH LOTS OF JERKING. THEN AN ENGINE LIGHT CAME ON, OFF, ON, OFF, ON, OFF (MANY TIMES) AND SAID SOMETHING ABOUT TRACTION CONTROL / STABILITY BAR (??). AT THIS POINT I HAD NO CONTROL OF MY SPEED/JERKING MOVEMENTS (SPEED DWINDLED DOWN). (ROAD CONDITIONS WERE GOOD, NO RAIN OR BAD WEATHER, NO CURVES, NO HILLS - STRAIGHT STRETCH OF ROAD) IT LASTED FOR ABOUT A MINUTE OR TWO. NEXT IT WAS OK. I TOOK IT IN TO THE DEALERSHIP AND THEY COULD NOT FIND ANYTHING. THEN IT HAPPENED AGAIN A FEW WEEKS AFTER THAT - OUT OF STATE - GOING DOWN INTERSTATE - SAME THING, (ROAD CONDITIONS PERFECT) LASTED A LITTLE LONGER THIS TIME. BROUGHT IT TO THE DEALERSHIP AFTER WE HAD GOTTEN BACK HOME - IT (SHOP'S COMPUTER) SHOWED THAT A LIGHT HAD COME ON - BUT IT DID NOT RECORD ANY INFORMATION. THIS IS A SCARY SITUATION.
