2012 KIA RIO Fuelpropulsion System Problems

Our granddaughter bought this car from a private seller. My son is a mechanic and when he inspected the undercarriage he found a small leak in the seam of the gas tank. The local KIA dealer said it is not covered. This, to me, is a safety and emissions issue. Please assist. The car is available at any time for inspection. Thank you

2012 KIA RIO, NOT CURRENTLY SUBJECT TO ANY RECALL, AND HAVING BEEN MAINTAINED CORRECTLY, IS EXPERIENCING DANGEROUS LEVELS OF OIL CONSUMPTION. CURRENT MILAGE 108,000. TWO WEEKS AGO I SENT THE ATTACHED LETTER VIA CASE TO KIA CONSUMER CUSTOMER AFFAIRS SEEKING SAFETY ADVICE FROM THE COMPANY RELATING TO THE ISSUE. KIA NEVER RESPONDED, OPTING TO CLOSE THE CASE WITHOUT A WORD REGARDING THE ISSUE. OIL CONSUMPTION IS VERY HIGH, AND EFFECTING ENGINE PERFORMANCE. I ASSUME THE ONLY RECOURSE IS TO HAVE THE ENGINE TAKEN APART AND EXAMINED, A COSTLY REVIEW, HOWEVER DUE TO LACK OF RESPONSE FROM KIA I HAVEN'T YET; I WAS HOPING THEY COULD COORDINATE THROUGH EITHER A DEALER OR 3RD PARTY INVESTIGATOR. CURRENTLY THE CAR IS NOT BEING USED, AS THIS ANOMALOUS ISSUE IS A CONCERN FOR SAFETY WHEN DRIVING. CONSIDERING THE RECENT RECALL, AS WELL AS HOW THE SYMPTOMS ALIGN WITH PREVIOUSLY RECORDED ISSUES TO SIMILAR ENGINES,...

BRIEF LOSS OF THROTTLE CONTROL ALONG WITH ENGINE OVERSPEED POSSIBLY DUE TO DIRTY ELECTRICAL CONTACTS IN CONNECTOR AT ELECTRONIC THROTTLE BODY -- RESTORED PROPER OPERATION VIA FLUSHING OF ELECTRICAL CONTACTS IN CONNECTOR WITH 100% ISOPROPYL ALCOHOL AEROSOL SPRAY -- VEHICLE WAS BEING DRIVEN INTO A CROWDED PARKING LOT AT THE TIME -- BRAKES WERE EFFECTIVE IN KEEPING THE SPEED UNDER CONTROL -- HAD TO SHUT ENGINE OFF WHILE IN DRIVE IN ORDER TO KEEP IT FROM OVERSPEEDING -- ENGINE HAD BEEN RUNNING AND CAR HAD BEEN IN MOTION FOR PREVIOUS 45 MINS WITHOUT PROBLEMS

CAR PAUSES AND THEN EXHILARATES WHEN DRIVING OR BACKING UP FOR EXPLANATION AND ALSO WANTS TO STALL WHEN PUSHING ON THE GAS WHEN TRYING TO GET ON HIGHWAY..

THIS IS MY SECOND POST. MY FUEL SYSTEM HAS BEEN ACTING UP THE LAST 1-2WKS. I NOTICED WHILE DRIVING ONE DAY THAT THE FUEL LIGHT CAME ON AND THE NEEDLE MOVED TO EMPTY ON MY DASHBOARD. I HAD PUT A FULL TANK OF GAS IN MY CAR LESS THAN 24HR EARLIER AND ONLY DRIVEN 20MI. SO I WAS QUITE ALARMED. I STOPPED TO CHECK MY FUEL CAP. CHECKED FOR LEAKS. BUT THERE WAS NO OBVIOUS ISSUE. THE LIGHT EVENTUALLY WENT OFF AND THE NEEDLE ROSE BACK UP TO THE FULL READING. WEIRD OF COURSE. I FIGURED IT WAS A GLITCH SO I DIDN'T THINK MUCH OF IT. HOWEVER THE SAME ISSUE CONT'D TO OCCUR OVER THE NEXT SEVERAL DAYS. AND MY CHECK ENGINE LIGHT EVENTUALLY CAME ON. TOOK VEHICLE TO AUTOZONE AND WAS TOLD THERE IS AN ISSUE W/ MY FUEL SENSOR SYSTEM. GREATNESS NEWS EVER B/C I AM STILL...

THIS CAR HAS A TENDENCY TO REV UP TO THE RED LINE ON THE TACH - SOMETIMES WHEN YOU START IT, SOMETIMES WHEN YOU ARE IN TRAFFIC, SOMETIMES WHEN YOU ARE STOPPED AT A TRAFFIC SIGNAL. I HAVE WITNESSES TO THIS FACT AND IT IS MAKING ME FEEL VERY UNSAFE WHEN I AM DRIVING IT. I ALMOST GOT IN TWO ACCIDENTS BECAUSE OF THIS CONDITION. IT MAY APPEAR IF I AM DRIVING DOWN THE HIGHWAY A COUPLE TIMES THIS OCCURRED AND THE ONLY WAY THAT THIS IS REMEDIED IS TURNING OFF THE IGNITION AND RESTARTED IT, SOMETIMES YOU HAVE TO DO THIS 2 OR 3 TIMES. OTHER TIMES IT WILL HAPPEN WHEN YOU START THE ENGINE IT WILL GO RIGHT TO THE TOP OF THE TACH IF YOU DO NOT TURN OFF IGNITION. IT HAS ALSO HAPPENED AT A TRAFFIC LIGHT STOP I FELT THE CAR INCREASING IN REVS WHILE...
