I have a fuel leak coming from the top of the fuel tank and running down the side of the tank. The leak occurs when the vehicle is running so it's appears to be coming from the high pressure fuel line or top of the fuel pump. It appears to be exactly what is described in NHTSA Campaign Number 18V358000 and in GMC Recall 18188 however GMC Customer Support told me recall 18188 only applies to the 2018 year model and not my 2017. When I search for recalls on NHTSA by VIN it tells me 0 unrepaired Recalls. My wife and I both smelled gasoline Friday afternoon when we returned from a trip. We have not driven the vehicle since. I started the vehicle and let it idle in our driveway and after a couple of minutes fuel began to leak and run down the side of the gas tank.
I HAD 4 LOADS OF MULCH LOADED IN MY 2017 GMC CANYON IN EARLY JUNE 2019. SOME MULCH FELL BETWEEN THE CAB AND CARGO BOX WHERE IT SMOLDERED ON TOP OF THE TRUCK GAS TANK FOR WEEKS UNTIL IT MELTED TUBES PROMPTING ONSTAR TO SEND ME TWO EMAILS 6-27-19 AND 6-29-19 TO SEE MY GMC DEALER WITHIN 7 DAYS FOR "AN ISSUE WITH THE EMISSION SYSTEM". THE DEALER IGNORED MY FIRST VISIT AND MAY HAVE IGNORED THE SECOND BUT NOW THE VEHICLE WOULD NOT ALLOW ME TO PUMP GASOLINE DUE TO A MELTED TUBE AND OTHER PARTS ON TOP OF THE FUEL TANK. I DISCOVERED THAT THE GAP THAT ALL PICKUP TRUCK HAVE, HAD NOTHING TO DIRECT MULCH AWAY FROM THE FUEL TANK. IF I HAD ANY IDEA THIS WAS HAPPENING I WOULD HAVE COVERED THE GAP WITH A TARP WHILE HAVING MULCH DUMPED IN. I FEEL VERY LUCKY TO BE ALIVE. MY WIFE AND I TOOK A LONG DRIVE AND THE TRUCK THEN PARKED IN OUR ATTACHED GARAGE WHILE WE WATCHED TV A FEW FEET AWAY. I CAN'T HELP BUT WONDER IF THIS IS THE FIRST TIME THIS HAS HAPPENED OR HAVE MANY BEEN KILLED IN MYSTERIOUS EXPLOSIONS THAT DESTROYED THE EVIDENCE. *JS
