Open the full vehicle complaint log (all categories)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
I WAS SLOWING DOWN TO A RED LIGHT AND THE CHECK ENGINE LIGHT CAME ON AND THE CAR DIED. I TURNED THE KEY SO I COULD BEGIN TO TRY TO START THE VEHICLE AND I NOTICED THE RPM'S START REVVING UP AND ITS TRYING TO OVER-ACCELERATE WHEN I PUT IT IN DRIVE. I MANAGED TO GET IT TO A SAFE SPOT BUT I WAS 100% WORRIED IT WAS GOING TO CAUSE AN ACCIDENT OR ACCELERATE OUT OF CONTROL. IT SOUNDS VERY IF NOT EXACTLY SIMILAR TO A LOT OF THE OTHER COMPLAINTS. NO CODES COME UP FOR THIS ISSUE AND IT IS SERIOUS. *TR
2004 KIA AMANTI ENGINE RACES AND LUNGES FORWARD WHEN APPLYING THE BRAKES AT STOP SIGN. THIS HAS HAPPENED 5 TIMES AND KIA SAYS THEY CAN NOT DUPLICATE IT SO NOTHING HAS BEEN DONE. *TR
I WAS STOPPING FOR A STOP SIGN AND ENGINE SUDDENLY RACED AND COULD NOT DEPRESS THE BRAKE PEDAL HARD ENOUGH TO STOP. SHIFTED INTO NEUTRAL AND ENGINE STOPPED RACING AND CAR SCREECHED TO A HALT. THIS HAS HAPPENED FOUR TIMES IN LAST TWO YEARS AND EACH TIME I HAVE SHOT THROUGH THE STOP SIGN. I TOOK CAR TO DEALER AND EACH TIME WAS TOLD THAT THIS HAS NOT BEEN REPORTED BY ANYBODY ELSE AND COULD NOT BE DUPLICATED. I WAS TOLD IT COULD BE A POSSIBLE VACUUM LEAK, BUT AN INDEPENDENT BRAKE SPECIALIST HAS TOLD ME THERE ARE NO LEAKS AND THE BRAKES ARE FINE. NOTHING ELSE HAS BEEN DONE. I AM REPORTING THE LATEST INCIDENT. *TR
TL*THE CONTACT OWNS A 2004 KIA AMANTI. WHILE DRIVING APPROXIMATELY 35 MPH, THE VEHICLE DID NOT RESPOND WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. IMMEDIATELY FOLLOWING AND WITHOUT WARNING, THE VEHICLE ACCELERATED WITH GREAT FORCE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER, BUT THEY COULD NOT DUPLICATE THE FAILURE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER ON FIVE SEPARATE OCCASIONS FOR IDENTICAL FAILURES, BUT THERE WERE NO RESOLUTIONS. THE THROTTLE BODY ASSEMBLY AND ACCELERATOR SENSOR WERE REPLACED. THE VEHICLE IS CURRENTLY BEING REPAIRED. THE FAILURE MILEAGE WAS 46,000 AND CURRENT MILEAGE WAS 54,000.
IN DECEMBER OF LAST YEAR I PURCHASED FROM CHARLIES KIA (AUGUSTA) A 2004 KIA "AMANTI". IT WAS WINTER AND ONE DOESN'T THINK TOO MUCH OF A CAR DOING ODD THINGS IN THE COLD. I DID NOTICE AS SPRING CAME ON THAT THE CAR SOMETIMES ACCELERATED VERY QUICKLY (ABRUPTLY) - ESPECIALLY DURING THE WARM-UP PERIOD. THE THROTTLE I'M TOLD IS ELECTRONICALLY GOVERNED. I'VE ATTEMPTED TO COMPLAIN TO KIA AND TO THE SERVICE DEPARTMENT AT CHARLIES. CHARLIES INFORMS ME THAT THE CAR IS NORMAL. I MAKE IT A POINT TO TELL ANYONE DRIVING MY CAR ABOUT THIS SITUATION (FAST ACCELERATION WITH _EXTREMELY _LITTLE HROTTLE PRESSURE). ALL THOSE THAT HAVE DRIVEN THE CAR DO REMARK (SOME QUITE NEGATIVELY). IN SHORT, I BELIEVE THE THROTTLE DRIVE TRAIN TO BE HAZARDOUS ON THIS VEHICLE AND I DON'T KNOW WHO OR WHERE TO TURN FOR ASSISTANCE IN RESOLVING THIS MATTER. INVESTIGATION ON THE WEB (WWW) REVEALS REMARKS ABOUT THIS PROBLEM, AS WELL. I AM PROMPTED TO WRITE THIS TO YOU AS I ONCE AGAIN BOLTED INTO TRAFFIC (CARRYING TWO PASSENGERS). NO ONE WAS INJURED! VERY SCARY, HOWEVER.
DT: THE CONTACT STATED THE VEHICLE ACCELERATED ON ITS OWN. THERE WAS NO WARNING, AND IT OCCURRED WITH OR WITHOUT THE CRUISE CONTROL ACTIVATED. THIS HAPPENED MORE OFTEN WHEN GOING UP A STEEP HILL. THE VEHICLE SLOWED DOWN WHEN THE BRAKES WERE APPLIED. THE VEHICLE HAS BEEN TO THE DEALERSHIP MULTIPLE TIMES FOR THIS, BUT THEY WERE NUNABLE TO DIAGNOSE THE PROBLEM. *AK
WHILE DRIVING AT HIGHWAY SPEED VEHICLE'S ACCELERATION DECREASED. THE GAS INDICATOR WENT FROM 18.1 TO 14.5 GALLONS. *AK
