Vehicle speed control

“I WAS ON THE HIGHWAY GOING OUT OF TOWN AND HAD THE CRUISE CONTROL SET LIKE I NORMALLY DO WHEN ALL OF A SUDDEN MY CAR DRASTICALLY LOST SPEED FROM 70MPH TO 45MPH ON A VERY BUSY HIGHWAY. I HAD TO SLOWLY MOVE OVER TO THE FAR LANE IN ORDER TO MAKE IT TO A SAFE PLACE TO PULL OVER. I THEN PULLED OVER SHUT THE CAR OFF FOR ABOUT 20 MINS AND TRIED TO COME BACK HOME AND ONCE AGAIN GOT ON THE HIGHWAY WHEN ONCE AGAIN I LOST POWER EVEN THO I'M PRESSING THE GAS ALL THE WAY DOWN TO THE FLOOR AND ITS NOT EVEN TRYING TO GAIN POWER AT ALL. I ALMOST GOT INTO 2 ACCIDENTS ON THE WAY HOME BECAUSE OF THE LOSS OF POWER. I HAVE SEEN A LOT OF COMPLAINTS ON THIS WEBSITE ABOUT THE SAME RECURRING PROBLEMS WITH OTHER KIA AMANTI OWNERS AND THIS PROBLEM NEEDS TO BE FIXED. THIS IS MY ONLY VEHICLE AND I'M SCARED TO DRIVE IT. PLEASE CAN SOMEONE GIVE ME SOME ANSWERS!!! *TR”

Engine

11 reports1 crash1 fire
“The 2004 Kia Amanti will accelerate on it's own. I have been in local traffic and it accelerates and de-accelerate like a run away horse. It will then drive normal. The check engine light comes on sometimes and goes back out. This last time the light came on, I took to an electrical auto repair place. The computer read out said it needed a throttle body. I replaced it as suggested. The 2004 Kia Amanti attempts to accelerate on it's own and stops and drives normal again. The check engine light is on again. I would like to get what is perfect and right for the Kia to perform better and be safe. How do I do that?”

“AFTER GETTING HOME LAST NIGHT FROM MY SISTER IN LAW'S GENDER REVEAL, I SAW SMOKE COMING FROM UNDER THE BONNET SO I OPENED IT QUICKLY AND SAW A FIRE BLAZING BEHIND THE ENGINE....WHEN THE FIRE DEPARTMENT GOT THERE, THEY POINTED OUT TO ME THAT THE FIRE WAS ELECTRICAL..... I NEED SOME FORM OF COMPENSATION FROM THE COMPANY AS I AM NO LONGER ABLE TO DRIVE THE CAR AND ELECTRICAL ISSUES ARE WIDELY AFFILIATED WITH THIS PARTICULAR MODEL OF KIA CARS.”
