Filed Sep 17, 2026 · Fuel system · AZ

2016 chevy colorado z71 v6. Sept.17,2026 took to mechanic because of bad gas smell in cab when window down and huge puddle of gas under truck. This could have exploaded very easily. Shop said high pressure line / fuel leaking severely and do not drive. There was no warning lights or any indication of a issue. I called the dealer due to a current GM recall ( number 18188 ) and they say my truck does not qualify but no one can explain why. I called GM and they said the same thing. This is clearly the same issue and online it just says 2015 to 2018 colorado trucks . No details on dates trucks made or anything. This needs to fixed and my truck and all other should be covered. I saw another guy on here dealing with same thing on the same year as mine. God help me if someone would have tbrow a cigarette out at the light when I had a foot wide puddle of gas under my truck. Also I have under 100k on this truck.

On October 3, 2025 the driver of the 2016 Chevy Colorado we own, left our house and drove .5 miles where he stopped for a red light. The light turned green and he accelerated to make a left turn. At that time, the gas gauge dropped to "E", the truck engine turned off, and gas emptied from the gas tank. The driver managed to coast the truck onto the curb and out of traffic. The gas smell was overpowering. This could have ended badly in many ways. Had he been driving on interstate, he would have been trapped, and any spark could have ignited the truck. Even the tow truck driver knew there was a gas leak without even examining the truck. The truck was towed to our house until arrangements were made tor the repair. The truck was towed again to the Chevy dealership (Total Tow Charges $344.85 invoices not available at this time). The repair shop found both the fuel pump and fuel feed cracked allowing gas to spew out. The VIN number was searched for the federal safety agency recall number 18V‑358 and the Chevy recall number 18188 and was not found. There were no warnings of the impending failure and no one was injured due to the failure. The vehicle repair was completed on October 15, 2025. Removed parts are available for inspection. We contend that the problem is related to the recall for the fuel pump in above recall numbers.

I detected the smell of fuel while the vehicle when it was both not running and running. I brought the truck to Banks Chevrolet in Concord NH. The high pressure fuel pump detached from its mounting flange, resulting in damage to the attaching high pressure fuel pipe causing a constant fuel leak. Dealer replaced the high pressure fuel pump and high pressure fuel pipe to resolve the concern. There is a the federal safety agency recall that my vehicle should have been included in, 18V358000. The GM recall number is 18188. I paid out of pocket (~$1500) to fix this safety issue when it should have been fixed initially with the recall.

* 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.

1)The exhaust system has leaked into the vehicles interior on at least two occasions May 7 2021 and July 24 2021. Arrangements can be made for vehicle inspection. We will be happy to help by any means we can. 2) There were both large amounts of exhaust fumes to the extent that I had to turn off the truck and exit the vehicle iimmediately. I might have died. Fortunately I was already parked so I did not need exit the roadway. It had been a long hot day in the mid to upper 90s I was about to take a brief nap in the vehicle and could have potentially died if I had fallen asleep as I was waiting in the parking lot on my partner to Complete a couple purchases and was anticipating about a 30 to 45 minute wait. The other time happen on May 7 2021 while my partner was driving on the highway by them self. The exhaust fumes were bad enough that all windows had to be rolled down and needed to exit hhhighway for the enext exit to park and exit the vehicle as soon as possible. Partner notes that they saw exhaust smoke/fumes coming iin from the vents with the air conditioner running . 3) The dealer has not been able to reproduce the problem. Vehicle has not been to a independent repair facility for the issue 4) No other inspections have been performed outside of dealership staff. 5) No warning lamps or messeges came on. The amount of exhaust fumes coming into the vechle was not a gradual ooccurrence but a sudden large amount of fumes.
