SPLIT FUEL TANK ON THE SIDE, 2ND FUEL TANK TO FAIL IN THE LAST 5 YEARS. HYUNDAI CLAIMS THERE IS NO PROBLEMS WITH FUEL TANKS, BUT GOOGLE THE SONATA FUEL TANKS AND THERE IS A TON OF COMPLAINTS. HYUNDAI WILL DO NOTHING ABOUT IT. NO RECALL, NO NOTHING. HOUSE AND GARAGE HAS SEVERE GAS SMELL AND A LARGE PUDDLE OF GAS ON THE FLOOR. *TR

BACKING INTO THE GARAGE, MY FOOT ON BRAKE, THE ENGINE SUDDENLY REVVED TO HIGH RPM, THE CAR SHOT BACKWARDS, PROPELLING A HEAVY RUBBER MAT ON WHICH THE CAR IS NORMALLY PARKED OUT OF THE GARAGE AND INTO THE DRIVEWAY. THE VEHICLE THEN IMPACTED AND CRASHED THROUGH THE REAR GARAGE WALL BEFORE COMING TO A STOP. I MANAGED TO PRY THE GEAR LEVER OUT OF REVERSE, HIT DRIVE INSTEAD AND SENT THE CAR, WHEELS STILL SPINNING AND LAYING DOWN RUBBER, FORWARD OUT OF THE GARAGE. ON ITS WAY OUT THE CAR SWIPED ALONG THE RIGHT SIDE THE GARAGE DOOR POST BEFORE FINALLY COMING TO A STOP IN THE DRIVEWAY. FINAL RESULT, SERIOUS DAMAGE TO BOTH THE CAR AND THE GARAGE. FORTUNATELY THIS DID NOT OCCUR IN TRAFFIC OR WITH PEDESTRIANS IN THE AREA. ON-LINE RESEARCH HAS SINCE SHOWN ME THAT THERE HAVE BEEN NUMEROUS OTHER SIMILAR INCIDENTS WHERE HYUNDAI SONATAS HAVE SUDDENLY ACCELERATED ON THEIR OWN.

TL* THE CONTACT OWNS A 2004 HYUNDAI SONATA. WHILE ADDING FUEL TO THE VEHICLE THE CONTACT NOTICED THERE WAS A SMALL VALVE ON THE OUTSIDE OF THE FUEL TUBE THAT FRACTURED AND POSSIBLY HAD FALLEN INTO THE FUEL TANK. THE CONTACT SMELLED A STRONG FUEL ODOR EMITTING IN THE INTERIOR OF THE VEHICLE AFTER IT WAS STARTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THE VEHICLE WAS NOT COVERED UNDER THE WARRANTY; THEREFORE, HE WOULD BE RESPONSIBLE FOR THE DIAGNOSTIC COST. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 47,000.

I HAVE A 2004 HYUNDAI SONATA V6 THAT GIVES ME PROBLEMS WHEN I FILL THE GAS TANK UP. I KNOW THAT THIS MIGHT SOUND CRAZY BUT, WHEN I GO TO START THE CAR, IT WILL NOT TURN OVER. I RECENTLY HAD A MAJOR TUNE-UP DONE ON THE VEHICLE ALONG WITH CHANGING THE TIMING BELT. WHEN I FILL UP MY CAR, I HAVE TO INCLUDE AN ADDITIVE SUCH AS GAS TREATMENT, LUCAS GAS TREATMENT, FUEL CLEANER, ETC. I HAD MY MECHANIC LOOK AT THE VEHICLE FOUR TIMES AND HE HAS FOUND NOTHING WRONG WITH THE VEHICLE. I ASK FOR ASSISTANCE TO DIAGNOSE THE PROBLEM AND WOULD YOU RECOMMEND BRINGING THE CAR TO A DEALER. PLEASE HELP! THANK YOU. THE SYSTEM WOULD NOT ALLOW ME TO ENTER MY VIN NUMBER. *TR
