NHTSA Complaint #10943975 — 2007 DODGE CALIBER AWD

I HAVE BEEN EXPERIENCING DIFFICULTY IN FILLING FUEL INTO THE GAS TANK. FUEL MUST BE ENTERED VERY SLOWLY IN THE FILLER NECK OR THE HANDLE FROM THE PUMP WILL "TRIP" AND NOT ALLOW ANY FURTHER FLOW OF FUEL. AFTER DOING SOME RESEARCH AND TALKING TO OTHERS I THOUGHT THIS PROBLEM MIGHT BE DUE TO A CLOGGED EVAP HOSE OR ITS CHARCOAL CANISTER. I TOOK IT TO AN NATIONALLY KNOWN SERVICE STATION WHO DIAGNOSED THE PROBLEM TO BE NOT IN THE EVAP SYSTEM BUT IN A DEFECTIVE "ROLLOVER VALVE" WHICH IS INTERNAL TO THE FUEL TANK. IT IS ESSENTIALLY A "CHECK VALVE" WHICH PREVENTS FUEL FROM SPILLING BACK OUT OF THE TANK IN THE EVENT OF A ROLLOVER ACCIDENT. IF THIS ROLLOVER VALVE IS STUCK "PARTIALLY CLOSED" DURING FILLING, THEN IT COULD ALSO BE STUCK "PARTIALLY OPEN" AND ALLOW FUEL TO DANGEROUSLY SPILL BACKWARD THROUGH THE FILLER NECK IN THE EVENT OF A ROLLOVER ACCIDENT. I TOOK MY VEHICLE TO AN AUTHORIZED DODGE DEALER TO INVESTIGATE THE ABOVE. THEY CHECKED INTO THEIR DATABASE AND FOUND THIS DEFECTIVE PART TO HAVE CAUSED A RECALL ON SOME OTHER 2007 DODGE VEHICLES (AVENGER, DAKOTA AND I BELIEVE RAM'S) BUT THE FREQUENCY WAS NOT JUSTIFIED FOR DODGE CALIBERS. IT IS MY BELIEF THAT MY PROBLEM DESCRIBED IS ONE AND THE SAME AS THOSE MODELS LISTED ABOVE (AND MAY VERY WELL BE THE SAME AFFECTED PART) AND THAT MY DEFECTIVE "ROLLOVER VALVE" SHOULD BE REPLACED AT DODGE'S EXPENSE. THE REPAIR INVOLVES REPLACEMENT OF THE ENTIRE FUEL TANK.
