2016 Chevrolet Silverado Fuel System Problems

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the fuel tank. The contact was informed that there was a crack in the fuel tank near the fuel sending unit. The vehicle was repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 19V088000 (Fuel System, Gasoline); but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 29,000.

Check engine light came on, code said EVAP leak detected, took it gm dealership and was told the fuel tank was leaking at the vents to the system and the tank would need to be replaced.

Engine light came on and the code shows fuel module control

smelling fuel in cab, found fuel line spraying fuel across bottom of truck, had it towed to dealer who replaced the line, which was cracked at the fitting closest to the fuel pump. Molded line cracked from age or vibration. 107k miles on truck. fuel spray could ignite imperiling the occupants. no warning lamps, engine was still getting fuel and ran fine. Concern for proximity to exhaust and catalytic converter as an ignition point.

The fuel filler injection port retaining clip became overly worn down & broke with minimal use, thus not holding the fuel spout in its proper place causing it to malfunction. No warning lights. Fuel spout is very loose & could come loose & cause disasters from: personnel injury/death, inhalation from toxic fumes, environmental disasters, etc. The fuel tank was completely replaced in 2016 right after purchase.

MY TRUCK HAS A BAD GAS SMELL WHEN ENTERING OR EXITING THE TRUCK. I LOOKED UNDERNEATH IT AND SAW A SMALL GAS LEAK COMING FROM THE TOP INSIDE OF THE TANK. THE TRUCK ONLY HAS 26000 MILES ON IT, AND IS JUST OUT OF WARRANTY. PLEASE INFORM ME IF YOU KNOW OF OTHER REPORTS OF GAS LEAKING ON THESE CHEVY TRUCKS

WHILE DRIVING DOWN THE HIGHWAY AND TRAVELING ON AN EXIT RAMP ABOUT HALFWAY THROUGH, MY VEHICLE MOMENTARILY "SHUDDERED" OR "LOST POWER" FOLLOWED BY THE CHECK ENGINE LIGHT FLASHING. THIS COULD HAVE RESULTED IN QUITE A SERIOUS ACCIDENT, HOWEVER I WAS ABLE TO RETAIN CONTROL OF THE VEHICLE AND PULL OVER IMMEDIATELY. WHEN I PULLED OVER, I CONNECTED MY CODE SCANNING TOOL AND PULLED A P0300 CODE FROM THE VEHICLE, MEANING IT HAD MULTIPLE/RANDOM MISFIRES. THIS COINCIDES WITH THE "SHUDDER". UPON TAKING THE VEHICLE TO THE DEALERSHIP TO GET A DIAGNOSTIC, THE SERVICE WRITER INFORMED ME THEY HAVE HAD QUITE A FEW VEHICLES WITH THE SAME ENGINE COME IN FOR MISFIRE ISSUES, USUALLY RESULTING IN FUEL INJECTORS BEING REPLACED OR THE FUEL PUMP. SEARCHING ONLINE, IT SEEMS TO BE A FAIRLY CONSISTENT ISSUE. MULTIPLE FORUMS HAVE BEEN DEDICATED TO IT, ALONG WITH MANY YOUTUBE VIDEOS DESCRIBING IT AND SHOWING HOW TO REPLACE THE INJECTORS OR FUEL PUMP. AS THIS SEEMS LIKE A WIDESPREAD ISSUE, I WOULD LIKE TO REQUEST THE NHTSA LOOK INTO THE MATTER AND MAKE A DETERMINATION. I WOULD HATE FOR A SIMILAR SITUATION TO HAPPEN TO SOMEONE AND THEY ARE NOT ABLE TO RETAIN CONTROL OF THE VEHICLE. *TR

WARRANTY ENDED IN JULY 2019. CHECK ENGINE LIGHT CAME ON IN NOV 2019 WITH A P050D CODE. VEHICLE ONLY HAS 32,0000 MILES. TOOK IT TO DEALERSHIP (AUTONATION CHEVROLET IN GILBERT, AZ) AND WAS TOLD TWO FUEL INJECTORS WERE THE CAUSE AND NEEDED REPLACED. THE DEALERSHIP SAID ONE OF THE INJECTOR FUEL RODS AND GASKET WAS INSTALLED BACKWARDS AT THE FACTORY. I PUSHED FOR GM TO PAY FOR THE REPAIR SINCE NO PREVIOUS INJECTOR WORK HAD BEEN DONE. THE EXCEPTION WAS CLEANING THE INJECTORS AS PART OF ROUTINE MAINTENANCE, WHICH OCCURRED IN AUG 2019 AND WAS COMPLETED AT DEALERSHIP. GM AGREED TO PAY HALF THE COST OF REPAIR. HOWEVER, I WHOLEHEARTEDLY BELIEVE THEY SHOULD'VE PAID THE ENTIRE COST SINCE THIS WAS CAUSED BY A FACTORY DEFECT. I BELIEVE THIS SHOULD BE LOOKED INTO BECAUSE IF MY INJECTORS WERE INSTALLED INCORRECTLY AT THE FACTORY, CHANCES ARE OTHER VEHICLES HAVE THEM INSTALLED INCORRECTLY AS WELL.

VEHICLE STARTED "COLD" IN HOME OWNER'S DRIVEWAY. POOL OF FLUID OBSERVED ON GROUND AFTER MOVING VEHICLE 50'. VEHICLE PUT INTO PARK, I EXITED VEHICLE, SMELLED GASOLINE AND PHYSICALLY OBSERVED GASOLINE SPRAYING OUT @ SYSTEM FUEL PRESSURE FROM A RUPTURED GAS LINE IN MID SECTION OF UNDERCARRIAGE. GASOLINE WAS ALSO SPRAYING DIRECTLY ONTO MUFFLER. VEHICLE SHUT OFF IMMEDIATELY. TURNED KEY ON WITHOUT STARTING VEHICLE AND GASOLINE AGAIN STARTED SPRAYING UNDERSIDE OF VEHICLE. FIRE DEPT. NOTIFIED AND RESPONDED TO INCIDENT. NO VEHICLE FIRE RESULTED, HOWEVER VEHICLE WAS STARTED "COLD" . I BELIEVE RESULTS WOULD HAVE BEEN CATASTROPHIC HAD THIS HAPPENED WITH VEHICLE AT FULL OPERATING TEMP. DEALERSHIP STATED MY GAS LINE RUPTURE WAS FIRST THEY HAD SEEN ON A NEWER VEHICLE AND IT WAS A COMPOSITE GAS LINE. IT TOOK A WEEK TO GET REPLACEMENT PART FOR REPAIR TO BE MADE. I HAVE REQUESTED TO SEE THIS GAS LINE OR GIVEN A PICTURE BY DEALERSHIP. REPAIR COVERED UNDER WARRANTY. THIS ISSUE POSES A SERIOUS FIRE/SAFETY PROBLEM TO OCCUPANTS IN AND AROUND VEHICLE AND NEEDS IMMEDIATE ATTENTION TO DETERMINE IF THIS TYPE OF GASOLINE LINE IS DEFECTIVE AND # OF VEHICLES POSSIBLY EFFECTED.

MY COMPLAINT IS VIBRATION OR A SHAKE. IT'S MOSTLY OCCURS OR WHEN I EXPERIENCE IT IS WHEN I'M AT A IDLE. I TOOK IT IN TO THE DEALER AND WAS TOLD IT WAS NORMAL. I SPOKE WITH SEVERAL MECHANICS AND A FEW MENTIONED THAT IT COULD BE THE OIL PRESSURE SENSOR FILTER THAT NEEDS TO BE REPLACED BUT SINCE THEIR IS NOT A LIGHT POPPING UP FOR A CODE,THEY CAN'T DO ANYTHING ABOUT IT. I'VE NEVER FELT THIS IN OTHER CHEVY OR GMC TRUCKS THAT I HAVE DRIVEN. WHY IS CHEVROLET IGNORING THIS ISSUE. TO JUST TELL AN OWNER OF A CHEVY TRUCK, OH IT'S THE "CHEVY SHAKE" AND BRUSH IT OFF IS NOT OK.
