I was getting ready to go out of town for work so before I left my home town. I went to a place to get my oil change. Before going everything was fine. I left there and literally 5 minutes after my car killed. Once it start back. The motor start making a noise it’s been parked
ENGINE BLEW DOING 40-45 ON A COUNTY ROAD 1,000 RPM 5TH GEAR, IN AUTOMATIC. 2ND TO 1ST, SOFT TO HARD KICK. VEHICLE SPEED SENSOR MUST BE FAULTY I HAVE TO PUMP BRAKE MORE TO SLOW THE ENGINE SPEED IT LIKES TO BOG TRYING TO SPEED UP IN AUTOMATIC MODE
WHEN COMING TO A STOP MY CAR SHIFTS FROM 3RD TO 2ND HER VERY ABRUPTLY. IT MAKES IT FEEL AS THOUGH I'VE SLAMMED ON MY BRAKES VERY SUDDENLY. IT ALSO DOES IT WHEN I SLOW MY CAR THEN PRESS THE GAS TO ACCELERATE SOMETIMES. I'VE TAKEN MY CAR TO THE DEALERSHIP OVER 5 TIMES SINCE FIRST PURCHASED BY MY MOTHER IN 2010 AND THE DEALERSHIP ALWAYS CLAIMED TO BE UNABLE TO NOTICE THE SUDDEN JERKING. THIS JERKING HAPPENS MOSTLY ON THE STREET DUE TO MY CONTINUAL STOP AND GO, BUT IT HAS ALSO HAPPENED WHILE GETTING ON THE FREEWAY AND DURING FREEWAY TRAFFIC.
TL* THE CONTACT OWNS A 2010 KIA OPTIMA. THE CONTACT CALLED ON BEHALF OF THE DRIVER. WHILE DRIVING 35 MPH, THE DRIVER LOST CONTROL OF THE VEHICLE AS IT INADVERTENTLY ACCELERATED. AS A RESULT, THE DRIVER STRUCK ANOTHER VEHICLE. THE CONTACT STATED THAT THE DRIVER HAD TO TURN OFF THE VEHICLE IN ORDER FOR IT TO STOP. THE AIR BAGS DID NOT DEPLOY. THE DRIVER SUSTAINED HEAD AND LEFT LEG INJURIES THAT DID NOT REQUIRE MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR DIAGNOSTIC TESTING OR REPAIRS. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 24,000. *TT *TR
VEHICLE JERKS WHEN DOWNSHIFTING AT ABOUT 20 MPH.
THE WEATHER STRIP ON THE WINDSHIELD ON THE DRIVER SIDE JUST STRARTED LIFTING UP AND COMING OFF AS I WAS DRIVING DOWN THE ROAD. I CHECKED THE DAMAGE AND SAW THE BLACK PIECE COMPLETELY OFF OF THE WINDSHIELD. IT CONTINUED TO LIFT MORE AS I DROVE. WHEN IT RAINED I BELIEVE WATER IS NOW IN THE SENSORS BECAUSE MY ODOMETER ONLY READS "ECO" ABOVE THE ACTUAL ODOMETER READING. IT BECAME SUCH A HAZARD WHILE DRIVING I HAD TO TAPE DOWN THE WEATHER STRIP JUST TO KEEP IT FROM FULLY COMING OFF MY CAR AND CAUSING FURTHER PAINT DAMAGE TO THE SIDE IT SMACKS AGAINST. NO MECHANIC WILL FIX THE ISSUE DUE TO BEING A MAUFACTURE ERROR AND I WOULD HAVE TO REPLACE THE ENTIRE WINDSHIELD IF I DID IT MYSELF. I HAVE CALLED KIA MANUFACTORS IN GA ONLY TO BE PLACED TO VOICEMAIL WITHOUT RESPONSE. I ASKED THE DEALERSHIP I BOUGHT THE CAR FROM AND THEY ALSO SAID TO CALL KIA.
WHILE DECELERATING, EITHER BRAKING OR COASTING, THE CAR WILL LURCH VIOLENTLY WHEN REACHING APPROXIMATELY 22 MPH. THE SEVERITY OF THE LURCH VARIES BUT IN MOST INSTANCES IT IS HARD ENOUGH TO SNAP MY NECK FORWARD. *JS
THE CRUISE CONTROL IS INOPERATIVE. THE CRUISE CONTROL LIGHT WILL COME ON, BUT YOU CANNOT "SET" THE CRUISE CONTROL. I HAVE READ ONLINE ABOUT SEVERAL OTHER KIA MAKES AND MODELS HAVING THIS SAME ISSUE. AS FAR AS I CAN RESEARCH, THERE IS NOT A FUSE FOR THE CRUISE CONTROL. *TR
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
