NHTSA Complaint #10785212 — 2008 HYUNDAI SANTA FE

WHEN THE GAS TANK IS LESS THAN HALF FULL, THE FUEL GAUGE DISPLAYS TANK AS NEARLY EMPTY AND THE AMBER LOW FUEL LIGHT APPEARS. THE CHECK ENGINE WARNING LIGHT ALSO COMES ON. THE FUEL GAUGE SWINGS BACK UP TO NEARLY HALF FULL, DROPS DOWN TO 1/4 FULL, THEN DROPS DOWN TO ALMOST EMPTY, THEN SWING BACK TO HALF FULL. ABOUT 3 MONTHS AFTER THIS PROBLEM STARTED, THE FUEL GAUGE REMAINS NEAR EMPTY WITH THE AMBER LOW FUEL LIGHT LIT. WHEN I FILL UP THE GAS TANK, THE FUEL GAUGE IS ONCE AGAIN ACCURATE UNTIL THE TANK GOES BELOW 1/2 FULL. HOWEVER, THE CHECK ENGINE LIGHT REMAINS ON AT ALL TIMES AND CAN ONLY BE CLEARED BY A MECHANIC. I'VE HAD MY MECHANIC CLEAR IT TWICE. THIS IS A FUEL SENSOR ISSUE WITH THE TWO SENDERS IN THE GAS TANK. I WAS GOING TO HAVE THIS REPAIRED BY HAVING THE FUEL PUMP ASSEMBLY REPLACED BUT FOUND OUT IT WOULD COST $1000. I CAN'T AFFORD THAT SO I'M STUCK. I'M GOING TO HAVE TO RESET THE ODOMETER EVERY TIME I FILL UP AND MAKE SURE I FILL UP THE TANK EVERY 300 MILES. I'VE DONE MY RESEARCH AND THIS IS A KNOWN, WIDESPREAD ISSUE WITH THE 2008 HYUNDAI SANTA FE VEHICLES. I SAW MANY COMPLAINTS ABOUT THIS ISSUE FILED ON THE NHSTA SO THIS AGENCY IS WELL AWARE OF THE ISSUE BUT HAS CHOSEN NOT TO RECALL THE SANTA FE FOR THE 2008 MODEL YEAR. I DON'T UNDERSTAND THIS: THIS IS A SAFETY ISSUE AS WELL AS A GROSS DESIGN AND MANUFACTURING PROBLEM WITH THIS VEHICLE. WE BOUGHT THIS VEHICLE USED WITH NO KNOWLEDGE OF THIS. THE FUEL GAUGE STARTED BEHAVING ERRATICALLY A LITTLE OVER A YEAR AFTER WE BOUGHT IT IN MAY 2014, WHICH WOULD BE AROUND LATE JULY 2015. HE FIRST SIGN OF A PROBLEM OCCURRED AFTER I FILLED THE GAS TANK IN LATE JULY 2015. THAT WAS THE FIRST TIME THE CHECK ENGINE LIGHT CAME ON EVEN THOUGH THE GAS TANK WAS FULL. I HAD MY MECHANIC CLEAR IT. THIS SAME THING HAPPENED ABOUT 6 WEEKS LATER. AFTER THAT THE ERRATIC FUEL GAUGE BEHAVIOR I DESCRIBED STARTED OCCURRING.
