2013 GMC Terrain Fuel System Problems

vehicle started running rough when driven, mechanic found fuel pump putting fuel into oil. could have caught fire! pump replaced and trashed. check engine light was only warning other then rought running engine.

When refueling, and having the fill nozzle locked on for auto shutoff, the fuel overflows and drains out of the fuel fill cavity and drips on the right rear tire. This usually results in gasoline smell in the car. This happens on most fuel nozzles. I should have reported it years ago.

The contact owns a 2013 GMC Terrain. The contact stated that the dealer had previously performed an unknown repair for an exhaust leak; however, the failure recurred while starting the vehicle. The contact stated while driving at an undisclosed speed, a fuel odor was detected. The contact was concerned that her and her passenger had experienced carbon monoxide poisoning. The vehicle was taken to an independent mechanic who reset the fuel carbon sensor and replaced the fuel cap; however, the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 115,000.

TL* THE CONTACT OWNS A 2013 GMC TERRAIN. WHILE DRIVING APPROXIMATELY 30 MPH, THE CONTACT NOTICED A FUEL ODOR. THE CONTACT ALSO NOTICED THAT THE FUEL GAUGE WAS LOWERING. THE CONTACT EXITED THE VEHICLE AND NOTICED A PUDDLE UNDERNEATH. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE FUEL LINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 18,000. UPDATED 09/27/16*LJ *CN

I WAS ABOUT TO SWITCH LANES ON HIGHWAY FROM ON RAMP TRAVELLING APRPOX 60 MPH AND ACCELERATING WHEN MY VEHICLE SUDDELING STOPPED ACCELERATING & SOMEONE PULLED UP ON MY SIDE TO INFORM ME I WAS LEAKING FUEL EVERYWHERE. I LOST NEARLY A FULL TANK OF GAS ON THE HIGHWAY. ONE OF THE MEN WHO STOPPED HAD WORKED ON GM VEHICLES IN THE PAST AND WAS ABLE TO CLIP SOMETHING TOGETHER TO SLOW THE LEAK. I DROVE TO THE DEALERSHIP AND THEY WERE NO HELP AND DIDN'T SEEM TO CARE ABOUT THE ISSUE OR HOW SERIOUS THIS WAS FOR A 2 YEAR OLD CAR WITH 37K MILES. I WAS TOLD I WAS OUT OF WARRANTY AND THEY WOULD NOT DO ANYTHING FOR ME AND WERE GOING TO CHARGE ME A $200 DIAGNOSTIC FEE. DISAPPOINTED BY THE POOR SERVICE I RECEIVED I TOOK THE CAR TO MY LOCAL MECHANIC WHO WORKS ON OUR OTHER VEHICLE. THEY WERE SHOCKED TO SEE A FUEL LINE ON A 2013 VEHICLE BREAK. THEY ORDERED THE REPLACEMENT FUEL LINE FROM GM AND I GOT MY CAR BACK ON 5 DAYS LATER. THE NEXT DAY I TOOK MY CAR OUT TO RUN ERRANDS AND WHEN RETURNING TO THE VEHICLE I NOTICED A STRONG SMELL OF GAS, UPON LOOKING UNDER THE CAR I NOTICED THAT THE FUEL LINE WAS STILL LEAKING AND FROM THE SAME PLACE! WE BROUGHT THE VEHICLE BACK TO THE SHOP AND THEY IMMEDIATELY GO IN TOUCH WITH GM WHO SENT OUT ANOTHER REPLACEMENT PART AND ALSO RECOMMENDED ALSO REPLACING THE METAL LINE AS THEY HAD BEEN SEEING SOME ISSUES WITH THIS LINE. UNDER THE RECOMMENDATION OF GM THE SHOP REPLACED BOTH LINES AND I GOT MY CAR BACK 3 DAYS LATER. THE PROBLEMS I HAVE EXPERIENCED ARE UNACCEPTABLE AND COULD BE VERY DANGEROUS. FORTUNATELY NO ONE WAS HURT BUT HAD I BEEN IN THE HIGH SPEED LANE AND TRAVELING AT FULL SPEED LIMIT WHEN THIS HAPPEN I OR SOMEONE ELSE COULD HAVE BEEN SERIOUSLY INJURED BY THIS ISSUE. GIVEN THE AGE OF THE CAR AND LOW MILEAGE THIS IS NOT A WEAR AND TEAR ISSUE, THIS IS 100% A DEFECTIVE PART OR MFG PROBLEM THAT I EXPECT GM TO REIMBURSE $670 FOR REPAIR.

WE LIVE IN CALIFORNIA AND THE CARB FUEL PUMP NOZZLES ARE CUMBERSOME BEASTS. BUT THE NOZZLE POPS OUT OF THE FUEL FILLER WHEN PLACED ON AUTO-FILL AT 4 OUT OF 5 GAS STATIONS. IT'S DANGEROUS WHEN IT POPS OUT AND FALLS ON THE GROUND SOMETIMES PUMPING GAS ALL OVER. I TOOK THE TERRAIN TO THE DEALER AND OF COURCE THEY CAN'T FIND ANYTHING WRONG WITH IT. WHAT GIVES AND WHAT'S THE FIX?

WHEN THE GMC TERRAIN IS FIRST STARTED IN THE MORNINGS THE VEHICLE "MISSES" FOR ABOUT 5 SECONDS. IT SOUNDS LIKE THERE IS CONDENSATION IN THE FUEL LINE. AFTER ABOUT 5 SECONDS THE VEHICLE SMOOTHES OUT AND RUNS NORMAL. THIS HAPPENS ALMOST EACH AND EVERY MORNING. IT DOES NOT HAPPEN ANY OTHER TIME. *TR
