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.

While driving my family home on a hot 90+ degree day. My 2016 Chevy Colorado suddenly has a power loss engine died and i went from 75 to parked in less than 30 seconds. Luckily I was able to pull off the freeway to the median. We were almost hit by two vehicles pulling a trailer and the other pulling a RV. I had to have someone pick my kids up due to the hazards of being stranded on the side of the freeway. We had to have the truck towed. The code we got was for a fuel pump control module. We replaced and had it programed. This did not fix the issue. After further diagnostics from a auto mechanic shop, which we had to pay out of pocket. We learned it was a lifter failure. I have see numerous forums and people sighting "Lifter Failure" in Chevy Vehicles. Where most of us owners have to cover all cost out of pocket. Yet still "NO RECALL" for this issue that seems to be worth a recall. Next Issue the speed sensor which we have replaced it 3 times now in less than 2 years.

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.

Yes I am filing a complaint due to my high-pressure fuel pump line and also the fuel pump. The fuel pump works but it is very dry rotted on the top therefore resulting in a lot of cracks and pressure loss. I have a 2016 Chevy Colorado four-door. When I go to look up recalls there is recalls on the 2016 to 2018 Chevy Colorado’s due to this exact problem. But when I call Dell Earnhardt Chevrolet in Tallahassee Florida they state that it does not include my Vin number. I think it’s kind of funny that my truck is having this exact issue but not this phone number please obviously the recall needs to be expanded to include my Vin numbers. Anyway it goes I have a 2016 Chevy Colorado that I paid cash money for and there is no way should my fuel pump be dry rotted and cracked like it is and the fuel pump is still in working condition. What led me to this diagnosis was I was driving down the highway when multiple times my vehicle jaunted to a halt. I was able to crank it back up and go a few more miles before it would happen again. At this point I took it to my mechanic to put it on a code reader and it was reading fuel pump modular. I Cut a hole in the bed of my truck and was able to save fuel spraying everywhere for my high-pressure fuel pump line. I ordered this line from Dale Earnhardt Chevrolet for $62. When we get there and put the line on the fuel pump it is the fuel pump nipple and the top of the fuel pump is extremely dry rotted and cracked. There is no way should the fuel pump be dry rotted and crack on a six year old vehicle. Like I said the light never came on till after a few times of shouting me to a halt and this is my complaint
