2017 Chevrolet Colorado Fuel system Problems

There is a major fuel line leak just before the high pressure fuel pump. It appears that the fuel line aggressively rubbed against an A/C line component (looks like a muffler/canister). This rubbing created a huge hole in the high pressure fuel line, causing diesel to spray everywhere on the driver side of the engine compartment. This causes a massive safety issue due to diesel fuel uncontrollably spraying onto hot engine components. In my own research, this seems to be a known problem for GM. I believe there is a TSB published for this exact problem, but I have yet to find the document online. This needs to be an official recalled item ASAP.

2017 Chevrolet Colorado pickup with 58,000 miles. Check engine light came on. Scanner reading by a repair shop indicated a EVAP issue. I declined the $1200 repair estimate. I paid for diagnosis of problem $200. I repaired the system by "cleaning 2 filters at the beginning of the fuel tank ventilation system. The "primary filter and hose are located in a especially dusty area on the pickup truck and is prong to plugging if regularly driven on rural gravel roads. Nothing in the owner's manual indicates the service is required of this filter. FILTER SHOULD BE RELOCATED TO ENGINE BAY. Check engine light was reset and has not come back on. NOTE: This is part of the pollution equipment that stopped working properly before 10yr. or 100,00 miles.

Fuel leak in line. There is a pin hole in the line spewing fuel under pressure when running. The fuel flows down the side of the tank as I reported in Complaint Number 11587383 on May 7th, 2024. Now I have removed the bed to discover said leak. Adding picture of the leak spewing fuel from line, by "P E" lettering on the line This is a major concern as any flame near the vehicle would cause it to go up in flames. The manufacturer should correct this problem. I see no reason why this hard plastic pipe developed a hole. It is product defect.

* Smell gas and discover leaking down driver side of fuel tank after parking, so something on top. Maybe fuel pump or ?. It is available for inspection. *Fuel puddle under vehicle in parking lot. *Have not contacted dealer, just noticed and found lots of others with same issue online with the Chevy Colorado and GMC Canyon. *I am the only one who has inspected to date. *No warning of any kinds, except stepping out of truck and heavy GAS smell, and seeing a shine of color in the rain water going to parking lot drain.

Recently I had a strong gasoline smell and leak coming from the vehicle. I took my truck in for inspection, and the mechanic said the fuel pump was damaged. The mechanic took a picture of the damaged fuel pump and could not explain how this part was destroyed in this way. I was charged $639 for the repairs. Since I am currently financing the vehicle, I researched to see if this particular make and model had any recalls. Upon discovery, it happens that in 2018 there was a recall that a high-pressure fuel pump may detach from its mounting flange, possibly resulting in the pump damaging the high-pressure fuel line. I phoned the manufacturer, and they said there was a recall for this issue for specific 2017 models but not for my truck's VIN. Since my vehicle has the same problem mentioned in the recall, I would like an investigation and possible recall on this model and vin since others may have this same problem. In my opinion, Chevrolet should reimburse me in full for damages that could have taken my family, my life, or any other motorist due to the gasoline leakage and damage to the fuel.

The contact owns a 2017 Chevrolet Colorado. The contact stated while her husband was driving 50 MPH, he smelled an abnormal fuel odor coming from the vehicle. He pulled over and noticed that the fuel gauge had indicated that the fuel was empty. With the help of his co-workers, her husband was able to push the vehicle into his job's parking lot. The contact then called the dealer where she was informed that they could not inspect the vehicle for another three weeks. Upon investigation, the contact discovered NHTSA Campaign Number: 18V358000 (Fuel System, Gasoline) which she linked to the failure however, the VIN was not included. The manufacturer was notified about the failure and informed her that her vehicle was not included in the recall. The vehicle was towed to a co-worker’s home where he was informed that the high-pressure fuel pump was defective and the part was replaced. The vehicle was repaired. The failure mileage was approximately 75,000.

THE ORIGINAL OWNER OF MY VEHICLE SUCCESSFULLY HAD GM BUY BACK THIS TRUCK. THE NOX SENSORS AND WIRING HARNESS HAD BEEN REPLACED THREE TIMES WHICH CLEARED THE CODES AND ALLOWED THE VEHICLE TO APPEAR TO BE IN PROPER WORKING CONDITION. WHEN GM BOUGHT THE VEHICLE BACK FROM THE ORIGINAL OWNER, GM WENT THROUGH AND SUPPOSEDLY "FIXED THE ISSUE" AND BRANDED THE TITLE AS A MANUFACTURER BUYBACK AND PUT THE VEHICLE BACK ON THE MARKET TO THE GENERAL PUBLIC. I PURCHASED THIS VEHICLE KNOWING ALL OF THIS AND TRUSTING THAT IF GM SAID THEY FIXED THE ISSUE, THEY HAD REALLY FIXED IT. NOW I AM A YEAR INTO OWNERSHIP AND THIS VEHICLE IS STILL UNDER WARRANTY, HOWEVER THIS IS THE THIRD TIME THAT THIS SAME EXACT THING THAT THE ORIGINAL OWNER HAD AN ISSUE WITH HAS SURFACED. THE VEHICLE SPEED IS LIMITED WHEN THIS OCCURS MAKING THE VEHICLE DANGEROUS TO DRIVE ON THE ROADS. THE VEHICLE IS ALWAYS IN MOTION WHEN WHEN THIS OCCURS AND USUALLY ON AN INTERSTATE FAR FROM THE DEALERSHIP.

I BOUGHT THIS TRUCK NEW OFF THE LOT WHICH HAS BEEN IN THE SHOP IN EXCESS OF 10 TIMES FOR MULTIPLE ISSUES. THE 4X4 STARTED NOVEMBER 2017 I WAS TOLD IT WAS BECAUSE WE WERE HAVING ABNORMALLY COLD WEATHER AND IT WOULD COME OUT OF IT. IT HAS BEEN IN MULTIPLE TIMES SINCE THEN AND THEY WERE UNABLE TO DUPLICATE. CLUNKING IN REAR WAS DISMISSED AS NOTHING, COULD NOT DUPLICATE. I STARTED SMELLING BURNING PLASTIC, THEN WHEN STARTING MY VEHICLE IN THE MORNING THE EXHAUST SMELL WAS SO OVERPOWERING THAT IT WOULD GAG US. THE BURNING PLASTIC SMELL WAS INTERMITTENT WHILE DRIVING AND THAT WAS ONLY AFTER DRIVING THE TRUCK BETWEEN 2 TO 20 OR THE FULL DRIVE HOME AND SOMETIMES NOT AT ALL. I HAD BEEN NODDING OFF, GETTING MASSIVE HEADACHES AND SICK TO MY STOMACH WHILE DRIVING MY TRUCK, SO WAS MY DAUGHTER. NO MATTER WHAT THEY HAD MY TRUCK FOR, THEY COULD NOT DUPLICATE THE ISSUE AND I HAD A LOANER FOR A WEEK AT A TIME. I TOOK MY VEHICLE TO ANOTHER DEALERSHIP WHO JUST ENDED UP SEALING MY PICKUP BOX, REPLACING FUEL PUMP MODULE, INSTALLED A BODY PLUG PER A BULLETIN, PER BULLETIN APPLIED LUBRICANT TO BOTH REAR LEAF SPRINGS AND TORQUED LEAF SPRINGS TO SPECS. TRANSFER CASE CONTROL MODULE HAD A BULLETIN FOR WHICH MY DEALER STATED THEY PUT DIELECTRIC LUBRICANT. I WAS DRIVING A VEHICLE WITH MY CHILD IN IT WITH CARBON MONOXIDE POISONING US BASED ON THE SYMPTOMS WE WERE BOTH SUFFERING, EXACTLY WHEN WOULD THAT HAVE BEEN DUPLICATED, AT AUTOPSY???? I DON'T TRUST THIS TRUCK, I DON'T WANT TO DRIVE THIS TRUCK, I HATE THIS TRUCK NOW AND I AM STUCK WITH 5 YEARS OF PAYMENTS AND SOMETHING THAT TRIED TO KILL ME. HOW IS THAT FOR SAFETY!!!! MY OPINION ONLY!!!

IN COLD TEMPERATURES THAT THE NORTHERN STATES EXPERIENCE (AROUND 4 DEGREES F) THE TRUCK WILL INTERMITTENTLY DIE IN THE MIDDLE OF THE ROAD WHILE DRIVING. COMPLETE POWER LOSS WITH NO WARNING, WHICH SEEMS TO HAPPEN AT ANY TIME. WHEN THE WEATHER IS ABOVE 10F CONSISTENTLY IT SEEMS THERE ARE NO ISSUES. EXTREMELY DANGEROUS AND CAN LEAVE YOU SUDDENLY WITHOUT POWER WHILE DRIVING.
