CAR DRIVES WITH LOOSE STEERING AND CLUNKING NOISE THAT FAIRFAX KIA REFUSES TO TEST DRIVE IT LONG ENOUGH TO HEAR. JERKS LEFT SUSPENSION ON ROUGH PAVEMENT ON LEFT SIDE ONLY. THERE ARE LOTS OF BIG BOLTS ON THE LEFT STRUT AND I BELIEVE THESE BOLTS ARE EITHER DANGEROUSLY LOOSE OR THE STRUT ITSELF IS BROKEN. NOISE IS SUTTLE. HAVE COMPLAINED 3 TIMES TO DEALER.
BRAKES SQUICK EVEN AFTER REPAIR AND REPLACEMENT AND HAS A SLOWER RESPONSE TIME THEN USUAL AND CAUSED A REAR END ACCIDENT, COOLING AND HEATED SEATS STOPPED WORKING ON THE DRIVER SIDE WHICH I MET OWNERS OF MY EXACT CAR SAID THE SAME THING HAS HAPPENED TO THEM, AND THE PASSENGER SEAT CONTROLLERS DOESN'T WORK TO OPERATE ADJUSTABLE SEATS! THE SUSPENSIONS HAS BEEN BAD EVERY SINCE THE RECALL ON THE ENGINE; FOR SOME REASON IT WAS GIVING BACK TO ME WITH THAT PROBLEM FROM KIA DEALERSHIP. BACK-UP CAMERA IS MALFUNCTIONING FOR YEARS NOW AND CAR DOESN'T EVEN BEEP WHEN GETTING TOO CLOSE TO OBJECTS/OTHER VEHICLES ANYMORE EITHER FOR YEARS! I'M JUST FINDING OUT ABOUT THE PROCESS, RECALL LAWS AND RIGHT TO AN INVESTIGATION.*DT*JB
IM HAVING INTERMITTENT ELECTRICAL AND SUSPENSION PROBLEMS ALONG WITH SUDDEN INCREASES OF POWER INCREASE AND DECREASES. I WAS DRIVING TO MY LOCAL MALL BEFORE MY EVENING CLASS AND NOTICED MY CAR RADIO AND INSTRUMENT CLUSTER WHERE NOT OPERATING NO LIGHTS BUT CAR WAS RUNNING FINE. I HIT THE BRAKES WHILE COMING TO A STOP LIGHT IN A BUSY INTERSECTION HIT A SMALL BUMP THE CAR DECIDED TO ACCELERATE AND IT FELT AS IF THE SUSPENSION WAS LOOSE ON THE LEFT FRONT SIDE I HEARD IT RATTLE NOW THIS BUMP WASN'T BIG BY ANY MEANS AS I HIT THE BREAK I COULD FEEL THE BRAKES FIGHT WITH THE ENGINE THE BRAKE PEDAL ALSO SHOOK AT MY FEET. I QUICKLY PUT THE KIA IN NEUTRAL AND SHUT THE CAR OFF STILL AT THE LIGHT. PUT IT IN PARK AND RESTARTED MY CAR ALL LIGHT AND INSTRUMENT CLUSTER CAME ON ALONG WITH RADIO.MY OPTIMA FELT OK . BUT LATER I WENT TO CLASS GOT INTO MY CAR AND SHE WOULDN'T TURN OVER I HAD TO PRESS ON THE GAS TO GET IT TO START. I TOOK IT TO THE DEALER THEY SAID THEY COULDN'T FIND ANYTHING BESIDES MY HIGH TEMP FUEL PUMP WAS GIVING LOW PRESSURE CODES. I ONLY HAVE 80K ON THIS VEHICLE BUT KIA SAID THEY WILL NOT COVER IT. THIS A SERIOUS SAFETY ISSUE WHY IF MY KIDS WHERE IN THE CAR AND I DID GET INTO A SERIOUS ACCIDENT WITH THEM . THIS NEEDS TO BE ADDRESSED. SOMETHING NEEDS TO BE DONE BEFORE THERE IS A DEATH NO AFTER THE FACT.
TL* THE CONTACT OWNS A 2012 KIA OPTIMA. THE CONTACT STATED THAT WHEN MAKING A TURN THE VEHICLE SHOOK VIOLENTLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 20,000 AND THE CURRENT MILEAGE WAS 34,000.THE VIN WAS NOT AVAILABLE.
AT 20000 MILES MY FOG LIGHTS WOULD NOT WORK , THE WEIRD PUT THE DIRECTIONAL SIGNAL TO TURN RIGHT THEY WOULD COME ON FOR A SHORT TIME, REPLACED BULBS NOTHING THEY DON'T WORK. ALSO HAD TO REPLACE BRAKES AND THE TIRES, TIRE BRAND ARE JUNK, POORLY MADE THEY WERE BEYOND THE LIMIT FOR SAFTY, THEN AT 40000 MILES BOTH FRONT WHEEL BEARINGS HAD TO BE REPLACED, NOW AT 78000 MILES THE STRUTS ARE MAKING A HORRIBLE CLANKING AND THE AC IS BLOWING HOT AIR EVEN AFTER 2 CANS OF THE STUFF THE MECHANIC SAID TO ADD. I TRAVEL ON THE HIGHWAY TO WORK 36 MILES ONE WAY DAILY HENSE THE MILAGE BUT THE HIGH WAY IS SMOOTH AS WELL. VERY DISAPPOINTED KIA OWNER, WHEN CALLED TO ASK ABOUT THE FOG LIGHTS WAS TOLD YOUR PROBLEM SO IM SURE THE STRUTS WILL BE AND THE AC WILL ALSO BE MY PROBLEM . SADLY THOUGHT THEY WOULD BACK UP THERE PRODUCT
RIGHT REAR SUSPENSION MAKES CREAKING NOISE, PROGRESSIVELY WORSE OVER TIME. SUSPENSION WAS GREASED UP, BUT PROBLEM RECURRED AFTER ONE WEEK. CONCERNS THAT ASSEMBLE MAY COME LOOSE WHILE DRIVING. NOISE WORSE ON UNEVEN SURFACES OR WHEN EIGHT IS REDISTRIBUTED TO RIGHT SIDE (E.G. DRIVE THROUGH WINDOWS SOMETIMES ELEVATE FROM THE LEFT CAUSING CAR TO LEAN ON RIGHT SIDE; UNEVEN PARKING LOTS WILL CAUSE CREAKING SOUND). *TR
THERE IS A KNOCKING SOUND THAT SEEMS TO BE ON BOTH SIDES OF THE FRONT END. I HAVE HAD THE CARE ALIGNED AND IT DOES NOT SEEM TO BE PART OF THE ALIGNMENT, ALSO INDICATIONS FROM OTHERS IS THAT IT IS RELATED TO SWAY BARN ENDS. OTHERS ON THE KIA FORUM INDICATE SIMILAR PROBLEMS..
