Gas line leak

Leaking fuel from the top of the tank when I start vehicle and after 5-10 minutes it stops this the second time this have happened

NHTSA ODI 11603586

Pinhole fuel leak located in the bend radius of a plastic, quick disconnect coupling, of a pressurized fuel line, just forward of the fuel tank. Being a pressurized line, the leak is continuous, whether the vehicle is on, or off. Due to the location of the leak, fuel is sprayed upwards onto other shielded lines and components, representing a safety/fire hazard.

Fuel pump leak. our cabin fills up with exhaust causing myself and my 3 young kids (1,3,5) to start coughing, eyes and throat burning, headaches & a hard time breathing. confirmed by GMC dealer in concord & separate auto shop. They told us it had a recall and that they couldn't fix it after paying them to diagnose it since it was recall. Now GMC dealer is telling us that the problem and recall exists for other 2015 Yukon models but our VIN # Is not included and that's why they never fixed the problem that I've been complaining about since I bought the truck (dont remember exact purchase date but the vehicle was new and under warranty for years). I've taken it to the dealership 3 times for the same problem (exhaust smell in cabin) and they kept saying it's fine. Now it's so bad that we can't drive it because it makes us feel sick.

Fuel injector is direct injection into cylinder. Excess carbon build-up is endemic with this design causing power loss/decrease, knocking, and potentially increased emissions. Safety factor is loss/decrease of engine power when needed for safe highway driving. This problem is noted in GM literature and technical bulletins. The Malfunction Indicator Light (MIL), also know as the Check Engine Light, illuminated and provided generic malfunction codes via the OBD. Cylinder #7 fuel injector removed and replaced, mechanic inspected the used injector. Heavy carbon build-up noted.

RAW FUEL FUMES INSIDE THE CAB AND OUTSIDE THE VEHICLE. AFTER LOOKING UNDER THE VEHICLE THERE IS A SLOW BUT STEADY FUEL LEAK FROM THE GAS TANK. I BELIEVE IT IS THE PLASTIC FUEL LINE THAT HAS WORN A HOLE IN ITSELF FROM RUBBING ON ANOTHER OBJECT.

WAS DRIVING DOWN THE ROAD AND SUDDENLY THE CHECK ENGINE LIGHT STARTED FLASHING AND THE ESP LIGHT CAME ON. I WAS VERY CLOSE TO HOME SO I DROVE BACK HOME AND AS I STOPPED THE CAR IT STARTED SHAKING AND I TURNED IT OFF. BROUGHT IT TO THE MECHANIC AND HE SAID THE FUEL INJECTORS NEED TO BE REPLACED. I HAVE BEEN WITHOUT MY CAR FOR 11 DAYS NOW AS THIS IS SUCH A COMMON PROBLEM THAT ALL THE PARTS ARE ON BACK ORDER. THIS IS VERY DANGEROUS AND NEEDS TO BE RECALLED ESPECIALLY AS IT IS SUCH A COMMON PROBLEM. FOR SUCH AN EXPENSIVE CAR THESE KINDS OF THINGS SHOULD NOT BE HAPPENING. HOPING FOR A RECALL SOON SO THAT I CAN RECEIVE MY MONEY BACK. *TR

AFTER DRIVING A 100 MILE ROUND TRIP ON A US HWY, COUNTY ROADS, AND CITY STREETS, WE ARRIVED BACK HOME AND BEFORE WE COULD TURN OUR 2015 GMC YUKON XL, WE IMMEDIATELY BEGAN TO SMELL GASOLINE. DIRECTLY UNDERNEATH WHERE OUR 8 MONTH CHILD WAS JUST SITING, IS WHERE WE NOTICED 87 OCTANE FUEL DRIPPING RAPIDLY. AS I WAS LOOKING, MY WIFE WAS REMOVING OUR CHILD OUT THE PASSENGER SIDE WHERE SHE WAS SITTING. WE HAD SO MUCH GAS ON THE GROUND AND THE FUMES WHERE SO STRONG. I CAN NOT STRESS ENOUGH HOW QUICKLY THE FUMES ENGULFED OUR WHOLE VEHICLE, WITH ALL OF US STILL IN THE VEHICLE. HAD THERE BEEN A SPARK OF ANY KIND, IT WOULD HAVE BEEN ENOUGH TO CATCH OUR VEHICLE ON FIRE WITH US POSSIBLE STILL IN THE VEHICLE AND MAINLY OUR INFANT STILL IN THE VEHICLE. WE HAD THE VEHICLE BROUGHT TO A LOCAL REPAIR SHOP AND HAD TO HAVE OUR FUEL FEED LINE (ACDELCO PART# 84200274) REPLACED. THE ENGINEERS FOR GM, STUPIDLY HAD THIS FUEL LINE RUNNING THROUGH A MOLDED CLIP, THAT IS PART OF THE FUEL TANK, AND THE HOSE WAS 'SNAPPED' INTO IT TIGHTLY. THIS CAUSED ENOUGH FRICTION IN THE LINE MOVING BACK AND FORTH TO FINELY PLACE A HOLE IN THE FUEL LINE. NHTSA MUST TAKE THIS REPORT SERIOUSLY BEFORE IT COST THE LIFE OF SOMEONE THAT DOES NOT DESERVE BURNING ALIVE IN A VEHICLE. ISSUE THE RECALL IMMEDIATELY BEFORE THIS HAPPENS! MOST PEOPLE CAN NOT AFFORD A $350-$1,000 FIX OR MUCH LESS THE VALUE OF SOMEONE'S LIFE!

WHEN THE GAS PEDAL IS DEPRESSED FULLY, THE GAS PEDAL STICKS THE CAR CONTINUES ACCELERATING. THE PROBLEM BEGAN WITH INITIAL COMPLETE DEPRESSION OF GAS PEDAL TO CAUSE SOME ACCELERATION AND DEPRESSING BRAKE ALLOWED VEHICLE TO RETURN TO NORMAL DRIVING. THE PROBLEM HAS WORSENED OVER TIME TO THE POINT WHERE BOTH FEET DEPRESSING ON THE BRAKE PEDAL DID NOT AFFECT ACCELERATION AND CAUSED SMOKE TO EMIT FROM BOTH FRONT BRAKE PADS, AND THE PASSENGER FRONT BRAKE PAD FLAMED UP FROM THE HEAT. THE CAR WAS DRIVEN INTO A PARKING LOT WITH THE BRAKE DEPRESSED THE ENTIRE TIME, AND TURNED OFF. SO FAR, THIS HAS ONLY HAPPENED WHEN THE GAS PEDAL IS FULLY DEPRESSED. THE DEALER TOLD ME THE MAT CAUSED THIS EVEN THOUGH THE MAT IS CUT AROUND THE GAS PEDAL WITH PLENTY OF ROOM TO NOT OBSTRUCT PEDAL. THE MAT ALSO DOES NOT SLIDE OR MOVE ABOUT THE AREA. THE GMC DEALER TOLD ME THEY TOOK THE MAT OUT AND DID NOT NOTICE ANY AUTO ACCELERATION, AND THEY TOLD ME THEY WERE UNABLE TO DEPRESS THE GAS PEDAL FULL TO ATTEMPT TO RECREATE THE PROBLEM, TO NOT COMPROMISE THE SAFETY OF THE OTHER CARS NEARBY.

FUEL SMELL INSIDE AND OUTSIDE OF VEHICLE WHILE DRIVING AND PARKED. EXTENDED CRANK AFTER (OVERNIGHT) ENGINE OFF PARK. FUEL PUDDLE NOTICED UNDER PARKED VEHICLE ON GARAGE FLOOR AND DRIVEWAY AFTER OVERNIGHT PARKING. SMELL AND FUEL LEAK SEEMED WORSE WITH A FULL TANK. ALSO NOTICED MORE FREQUENT AUTO SHUT OFF AT FUEL STATION DURING AUTOMATIC FILLING. DEALER DROPPED TANK AND FOUND A FUEL LINE THAT WAS 'RUBBED' THROUGH TO THE POINT OF FAILURE. I WILL DOCUMENT WITH PICTURES UPON MY RETURN TO THE DEALERSHIP IF NEEDED FOR FUTURE. I FIND THIS COMPLETELY UNACCEPTABLE THAT ON A ($70K) 3 YEAR OLD VEHICLE THERE IS A FUEL LEAK THAT COULD HAVE BEEN PREVENTED WITH A 10 CENT PIECE OF INSULATION TO PROTECT THE LINES FROM RUBBING. SOUNDS LIKE SOMEONE CHOOSE TO LOOK THE OTHER WAY DURING VALIDATION TESTING! TOTAL BS.
