NHTSA Complaint #10662165 — 2013 KIA OPTIMA

THE TRACTION CONTROL SYSTEM IS DESIGNED SO POORLY THAT WHEN I PULL INTO TRAFFIC FROM A STOP I HAVE TO DISABLE THE SYSTEM COMPLETELY OR RISK BEING A SITTING DUCK IN THE MIDDLE OF AN INTERSECTION. IT SEEMS THAT IF THE TRACTION CONTROL SYSTEM DETECTS ANY AMOUNT OF TIRE SLIPPAGE IT CUTS POWER TO BOTH WHEELS COMPLETELY. YOUR INSTINCT IS TO PRESS THE ACCELERATOR HARDER TO MAKE THE CAR GET OUT OF THE INTERSECTION WHICH CAUSES THE WHEELS TO SLIP WHEN THE CAR REAPPLIES POWER AND THE WHOLE PROBLEM STARTS AGAIN AND YOU ARE STILL IN THE INTERSECTION. THE POWER IS CUT SO DRAMATICALLY THAT IT IS ALMOST AS IF THE BRAKES ARE BEING APPLIED AND VEHICLE OCCUPANTS LURCH FORWARD. AFTER A SECOND OR TWO THE VEHICLE GRADUALLY REAPPLIES POWER. THE ONLY WAY TO AVOID THIS IS TO DISABLE THE SYSTEM WHICH HAS TO BE DONE EACH TIME YOU START THE CAR. IF YOU FORGET TO DISABLE IT YOU ARE FUMBLING ON THE DASH WHILE DRIVING TO DISABLE IT. WHEN I REPRODUCED THE EVENT AT THE DEALERSHIP THEY SAID THAT THIS WAS HOW THE SYSTEM IS DESIGNED TO WORK. ALL IT TAKES IS A COUPLE ROCKS ON THE GROUND, A LITTLE RAIN, OR EVEN A HEAVY FOG AND THE SYSTEM WILL COMPLETELY KILL THE POWER FOR BETWEEN 1 - 2 SECONDS WHEN YOU START OFF FROM A STAND STILL. *TR
