I BROUGHT CAR FOR A INSPECTION STICKER AND IT FAILED BECAUSE A SMALL VAPOR LEAK. THIS WAS DONE IN MAY OF 2015. THE REPAIR MADE WAS TO REPLACE THE CELLULOID IN ENGINE COMPARTMENT. WAS TOLD TO DRIVE VEHICLE SO COMPUTER COULD RESET ITSELF. WEEKS PASSED AND CHECK ENGINE LIGHT WOULD COME ON AND OFF. IT DID NOT WORK. BROUGHT BACK TO SHOP ONLY THIS TIME I NOTICED THAT THERE WAS A VERY STRONG GAS SMELL INSIDE AND UNDER CAR. WHEN MY MECHANIC LOOKED AT IT HE NOTICED 3 SMALL PIN HOLES IN THE TANK AND THAT'S WHERE WE GETTING THE VAPOR. I RESEARCHED IT FOR RECALL NOTHING FOUND CALLED DEALER AND WAS TOLD THERE WAS NOTHING ABOUT MY PROBLEM. DURING MY RESEARCH I CAME ACROSS MANY ARTICLES OF OTHER PEOPLE HAVING SAME PROBLEM. BUT HYUNDAI REFUSES TO ACKNOWLEDGE ANY PROBLEM WITH GAS TANKS.

AFTER ENGINE IS WARM, ABOUT 20 MINUTES LATER, THERE IS A GURGLING IN THE FUEL TANK WHEN THE KEY IS TURNED ON (BEFORE AND AFTER THE ENGINE IS STARTED). I THINK IT IS FUEL BEING RETURNED FROM THE ENGINE. I HAVE HAD IT IN TWO DIFFERENT HYUNDAI SERVICE SHOPS, WITH THE FUEL PUMP REPLACED TWICE, AND A FUEL PRESSURE REGULATOR REPLACED. HAVING GIVEN UP, BOTH SHOPS CONTACTED THE DISTRICT HYUNDAI OFFICE AND A FIELD SERVICE ADVISER TOLD THE LOCAL SHOPS TO SHOW THE EVENT AS "NORMAL". IT IS NOT NORMAL AND I THINK THE HYUNDAI DISTRICT OFFICE IS HIDING THE PROBLEM. COULD BE A FUEL SYSTEM PROBLEM AND COULD BE A SAFETY HAZARD IF FUEL STARTS LEAKING. BOTH LOCAL SERVICE DEPARTMENTS NOW SHOW THE PROBLEM AS "NORMAL" AND NOTHING MORE WILL BE DONE ON THIS PROBLEM. I BELIEVE A RECALL FOR THIS PROBLEM IS APPROPRIATE. *TR

EVERY SUMMER WHEN THE TEMPERATURE REACHES 100' RANDOMLY WITH OUT CAUSE MY 2006 HYUNDAI SANTA FE EXPERIENCES A PROBLEM WHILE DRIVING WITH THE A/C ON, WHERE THE PASSENGER COMPARTMENT SUDDENLY FILLS WITH THE TASTE AND SMELL OF RAW FUEL FUMES, CHOKING ME AND ANY PASSENGER IN THE VEHICLE,. THE VEHICLE HAS BEEN TO MY DEALER EVERY SUMMER FOR THIS SAME REASON,. THIS 12 AUGUST, THE 'INCIDENT HAPPENED WHEN I WAS ONLY 4.2 MILES FROM THE DEALER, AND ROVE DIRECTLY THERE, WHILE ON THE BLUETOOTH WITH HYUNDAI AMERICA. THE HYUNDAI SERVICE MANAGER AND SEVERAL SENIOR SERVICE WRITERS WITNESSED THE 'INCIDENT' GAS FUMES COULD BEE SEEN ROILING FROM UNDER THE HOOD,. FOR FOUR YEARS, SINCE I PURCHASED THIS VEHICLE, THE DEALER HAS BEEN UNABLE TO RE-CREATE THE PROBLEM, NOT ONLY DID THEY WITNESS THIS FIRST HAND , BUT DUPLICATED IT AGAIN,. AFTER MY CAR WAS RETURNED TO ME, AS HYUNDAI AMERICA REFUSED TO BUY THE VEHICLE BACK, I WAS TOLD BY A REGIONAL 'PARTS MANAGER', WHO CALLED ME FROM A CELL PHONE SO THE CONVERSATION COULD NOT BE RECORDED, AND TOLD ME THE PROBLEM HAD BEEN DOCUMENTED, HOWEVER, IT IS A PROBLEM UNIQUE TO MY CAR, AND FOR ME NOT TO DRIVE WITH THE A/C ON IN THE ARIZONA DESERT, DURING THE SUMMER,. *TR

SURGING. SOMETIMES WHEN APPLYING BRAKES, FEELS LIKE YOU ARE ALSO LAYING ON THE GAS PEDAL. OTHER TIMES, WHEN JUST BARELY ACCELERATING, IT'S LIKE TAKING OFF AT THE STARTING LINE. REAL SURGING, IT'S SCARY. MY WIFE DOESN'T LIKE DRIVING IT BECAUSE OF THIS PROBLEM. THE SERVICE TECH'S AT THE DEALER SAYS NOTHING IS WRONG, THAT IT IS DESIGNED TO DO THIS. I FIND THAT TO BE STUPID, OR NOT TRUE. *TR
