NHTSA Complaint #11298169 — 2012 KIA OPTIMA

MOST RECENTLY WHILE DRIVING MY CAR WITH VEHICLE IN MOTION ON CITY STREET (A STRAIGHT ROAD) IT ALL OF A SUDDEN DROPS POWER AND I AM UNABLE TO GET THE CAR TO ACCELERATE WITHOUT PUSH DOWN VERY HARD ON THE PEDAL UNTIL IT FINALLY DECIDES TO SPEED UP, ONCE THIS OCCURS THE TRACTION CONTROL LIGHT APPEARS ON THE DASH AND DOES NOT DISAPPEAR AND WILL NOT DISAPPEAR UNTIL THE CAR IS SHUT OFF AND RESTARTED AND THE LOSS OF POWER CONTINUES TO HAPPEN UNTIL THE CAR IS POWERED OFF. AFTER REALIZING THIS ISSUE I TURNED OFF THE CAR AND LET IT SIT A FEW MINUTES AND WHEN I POWERED BACK ON AND DROVE AGAIN THE SAME ISSUE OCCURRED AND THE TRACTION LIGHT REAPPEARED ON MY DASH. I AM CONCERNED THIS COULD BE A FAULTY PROGRAMMING ISSUE THAT IS TELLING THE CAR THE TRACTION IS NEEDED WHEN IT IS IN FACT NOT. THIS IS A SAFETY HAZARD AS THERE IS NO WAY TO PREDICT WHEN THIS POWER LOSS WILL HAPPEN AND DOES SO IN THE MIDDLE OF DRIVING WHICH SLOWS THE CAR WAY DOWN AND COULD CAUSE AN ACCIDENT AND ALSO HAVING TO CONTINUOUSLY KEEP THE ACCELERATOR DOWN UNTIL IT DECIDES TO REGAIN POWER IS DANGEROUS BECAUSE IT WILL SUDDENLY RAMP UP THE RPM AND TAKE OFF. THIS IS A MAJOR CONCERN AND COULD BE HAPPENING TO OTHER CONSUMERS.
