WHILE DRIVING ON A FREEWAY AT APPROXIMATELY 70MPH, MY SONATA STOPPED ACCELERATING. I HAD TO PULL OFF THE ROAD IN THE MIDDLE OF TRAFFIC AS MY CAR WAS RAPIDLY DECELERATING. I TURNED OFF THE IGNITION, AND AFTER LETTING IT SET FOR A FEW MINUTES, I WAS ABLE TO START UP AGAIN AND PROCEED WITHOUT TROUBLE. THIS HAS HAPPENED THREE TIMES IN SINCE, BOTH ON A FREEWAY AND ONCE ON A SIDE STREET. I AM ON MY WAY TO MY DEALER TODAY TO CHECK THIS OUT. ALSO, I HAVE CHECKED THE INTERNET, AND FOUND THAT THIS IS A COMMON OCCURRENCE AMONG THESE MODELS.

2009 HYUNDAI SONATA FUEL SENDING UNIT. *MW THE CONSUMER STATED IT HAS BEEN THREE MONTH AND THE SMELL OF GASOLINE/FUMES IS STILL PRESENT INSIDE AND OUTSIDE OF THE CAR, MOSTLY AT THE REAR PASSENGER SIDE WHERE THERE WAS A GASOLINE SPILL, AFTER THE PROBLEM WAS SUPPOSEDLY FIXED. ABOUT A MONTH AGO, THE VEHICLE STOPPED RUNNING, WHILE THE CONSUMER WAS DRIVING. IT ALL STARTED, WHEN THE CONSUMERS HUSBAND TOOK THE VEHICLE TO THE DEALER, BECAUSE THE CHECK ENGINE LIGHT HAD ILLUMINATED AND THE GAS GAUGE WAS NOT REGISTERING. THE MECHANIC CLEARED THE ENGINE LIGHT AND STATED THE FUEL SENDING UNIT NEEDED TO BE REPLACED. THE FUEL SENDING UNIT WAS REPLACED FOR A SECOND TIME, BECAUSE THE FIRST ONE WAS DEFECTIVE. HOWEVER, THE GAS GAUGE STILL DIDN'T WORK. IMMEDIATELY AFTER THE CONSUMER LEFT THE SHOP, SHE STOPPED FOR GAS AND WHILE PUMPING GAS STARTED POURING OUT FROM THE PASSENGER SIDE ONTO THE GROUND. THE CONSUMER STATED THE VEHICLE WAS TAKEN TO THE DEALER THREE TIME, FOR THE SAME PROBLEM. THE CONSUMER STATED EVER SINCE THE DEALER RE-INSTALLED THE GASKET, THE SAME FUEL SENDING UNIT CONTINUED TO LEAK GAS. *JB

THE CAR WOULD CRANK BUT NOT START. HAD THIS SAME PROBLEM ABOUT A MONTH AGO, THE CAR FINALLY STARTED AFTER SITTING AWHILE. THIS TIME WHEN IT HAPPENED I COULD NOT HEAR THE FUEL PUMP RUN. I DETERMINED THE FUEL PUMP WAS NOT WORKING. WHEN I WENT TO REMOVE THE FUEL PUMP I DISCOVERED THE ACTUAL PROBLEM WAS A DEFECTIVE ELECTRICAL CONNECTION INSIDE THE FUEL TANK. THE PLASTIC TERMINAL PROTECTION INSIDE THE TANK WAS BURNED THROUGH AND THE TERMINAL MELTED. THIS IS A VERY SERIOUS CONDITION AS IT WAS INSIDE THE TANK EXPOSED TO THE FUEL, AND COULD HAVE CAUSED A FIRE OR EXPLOSION. *TR

WHEN FILLING THE VEHICLE WITH GAS IT ALWAYS SPILLS OUT AS IF SOMETHING IS BLOCKING THE INPUT OF GASOLINE. I WOULD CONSIDER THIS A HAZARD/SAFETY ISSUE. MANY GAS STATION ATTENDANTS HAVE TOLD ME THIS IS A PROBLEM THEY SEE WITH MOST HYUNDAI SONATAS POSSIBLY OF THE SAME YEAR? I'VE CONTACTED HYUNDAI AND THEY WANT NOTHING TO DO WITH THIS. THEY WANT YOU TO JUMP THROUGH HOOPS TO HAVE IT REPAIRED. *TR

WHILE DRIVING ON THE INTERSTATE IN TRAFFIC, THE CHECK ENGINE LIGHT AND ESC LIGHT CAME ON AND IT WAS LIKE THE GAS DOESN'T WANT TO GO TO THE ENGINE BUT THE CAR DIDN'T DIE AND MOVED AT NO MORE THAN 5 MILES AN HOUR. THIS HAS HAPPENED SEVERAL TIMES OVER THE PAST4 MONTHS AND IT REALLY HASN'T BEEN AN ISSUE BECAUSE NORMALLY YOU CAN SHUT THE CAR OFF FOR ABOUT AN HOUR AND TURN IT BACK ON AND IT'S FINE, HOWEVER IT IS A MAJOR ISSUE IF YOU ARE UNABLE TO GET YOUR VEHICLE TO THE SIDE OF THE FREEWAY AND OUT OF HARMS WAY. IT HAS OCCURRED OVER 4 TIMES AND IT HAS RECENTLY HAPPENED TWICE IN ONE WEEK. I TOOK IT TO THE DEALERSHIP AND THEY STATED THAT HYUNDAI IS AWARE OF THIS ISSUE AND OWNERS CAN EITHER PAY TO GET THE SENSOR "BOX" CLEANED OUT, OR REPAIRED WHICH COSTS IN THE AREA OF $500.00. THEY KNOW IT IS THE SENSOR "BOX", AND THAT IS FLAWED. WHY SHOULD THE CONSUMER HAVE TO PAY FOR A DEFECT FROM THE MANUFACTURER. *TR

SOME TIMES WHEN STARTING THE CAR WITH MY FOOT ON THE BRAKE THE RPMS GO UP TO ABOUT 1200 AND THEN DOWN TO 800 RPMS. WHEN MY FOOT IS REMOVED FROM THE BRAKE THE CAR WANTS TO ACCELERATE AND GO ON ITS OWN OFTEN. WHILE STOPED AT A STOP SIGN OR STOPED WITH MY FOOT ON THE BRAKE THE CAR WILL LURCH FORWARD WHEN RELEASED, SOME TIMES SPINNING THE TIRES. IT IS PROGRESSIVELY GETTING WORSE AFTER RETURNING FROM A 5000 MILE TRIP IN JUNE, 2013. THE CAR PURCHASED NEW AND HAS A AUTOMATIC TRANSMISSION WITH APROX. 65000 MILES TOTAL ON THE CAR. THIS IS A ACCIDENT WAITING TO HAPPEN AND SHOULD HAVE A RECALL. *TR

NOTICED THE CAR DOES NOT PULL UP THE STEEP HILL VERY WELL. TOOK TO DEALER WHO SAID TRANSMISSION OIL IS DIRTY AND SMELLS BAD AND IT NEEDS TRANSMISSION FLUSH, RESETTING OF TRANSMISSION SHIFT POINTS, AND FUEL SYSTEM CLEAN . I POINTED OUT THESE ARE NOT PER SCHEDULED MAINTENANCE REQUIREMENT AND WAS CONCERNED THE CAR WAS CAUSING THESE PROBLEMS SO EARLY IN ITS USAGE . WILL TAKE IT FOR THE TRANSMISSION FLUSH AS THAT IS WHAT DEALER INSISTS ON BEFORE THEY INFORM ME IF THERE IS A SAFETY ISSUE PRESENT. *TR

THERE HAS BEEN AN ODOR OF GASOLINE ENTERING THE PASSENGER CABIN OF THE VEHICLE. I NOTICED IT IS "WORSE" WHEN I FILL THE VEHICLE WITH GAS BUT THE PROBLEM OCCURS MORE FREQUENTLY THAN THAT. I DO NOT TOP OFF THE TANK. THE PUMP SHUTS OFF WHEN FULL, AND I STOP PUMPING. THIS ODOR STARTS WHEN SITTING AT A STOPLIGHT AND STAYS IN THE CABIN UNTIL I'M MOVING AGAIN. I THOUGHT IT ONLY STARTED WHEN I CAME TO A STOP AT A LIGHT AND SAT FOR A COUPLE OF MINUTES, HOWEVER WHEN I WAS DRIVING HOME AT SLOW SPEEDS (15-25 MPH) CONTINUOUS, THE SMELL WAS CONSTANT. LATELY IT IS SO BAD I HAVE TO ROLL DOWN THE WINDOW. ONE TIME, I ALMOST PULLED OVER AT THE ROADSIDE, AND WAS GOING TO GET OUT OF MY CAR TO GET FRESH AIR, BUT THERE WAS TOO MUCH TRAFFIC. THERE ARE NO FUEL LEAKS THAT I CAN FIND. NO STANDING FUEL UNDER THE CAR AFTER I PARK. IT HAS DONE THIS MOST TIMES I'VE DRIVEN THE CAR TO MORE OR LESS DEGREES, BUT NOT EVERYTIME - MOST TIMES. I HAVE NOT BEEN TO A DEALER YET, BUT I WILL BE TAKING IT IN TO HAVE IT CHECKED. APPARENTLY THERE ARE QUITE A FEW OTHER OWNERS OF THIS CAR WHO HAVE NOTICED THIS SAME THING BASED ON A HYUNDAI INTERNET FORUMS. BUT I DID NOT HAVE THIS PROBLEM UNTIL 2010. I CAN'T IMAGINE THAT THIS IS NOT A SAFETY ISSUE WITH THE GAS ODOR. NOT ONLY ARE PASSENGERS HAVING TO INHALE THESE FUMES, BUT I'M WONDERING IF IT COULD BE A POTENTIAL SOURCE OF FIRE/EXPLOSION. I'M NOT SO SURE THESE ARE JUST VERY FEW, ISOLATED INCIDENTS. I SEE A PROBLEM STARTING TO EMERGE. CERTAINLY, I WILL NOT DRIVE A CAR THAT I HAVE TO SMELL GAS FUMES NEARLY EVERY TIME I DRIVE IT, NOT EVEN TO MENTION THE PROFOUND SAFETY PROBLEM THIS MAY CAUSE. *TR

1) WAS MAKING A RIGHT TURN INTO A PARKING LOT. THERE WAS A SLIGHT INCLINE. THERE WAS A QUARTER OF A TANK OF GAS IN THE CAR. 2) THE ENGINE APPEARED TO TURN OFF, HOWEVER THE ELECTRONICS NEVER TURNED OFF. POWER STEERING WAS NO LONGER AVAILABLE ONCE THE ENGINE STOPPED RUNNING. 3) I ATTEMPTED TO RESTART THE CAR, BUT IT WOULDN'T START. YOU COULD HEAR THE ENGINE TRYING TO START. I PLACED THE CAR IN NEUTRAL AND PUSHED IT INTO A PARKING SPACE. ABOUT 5 MINUTES LATER I SUCCESSFULLY RESTARTED THE CAR. I HAD THE CAR TOWED TO THE DEALERSHIP AND THEY COULD NOT DIAGNOSE THE PROBLEM OR DETECT THAT ANYTHING HAD OCCURRED. *TR
