2015 Chevrolet Tahoe: gas smell in the cabin

Filed Dec 26, 2025 · Fuel system · IN

Vehicle cranked longer than usual, noticed slight smell of fuel. After arriving home noticed fuel smell was very strong and a puddle of raw fuel under vehicle. Fuel line appears to have rubbed/vibrated against the frame of the vehicle causing the line to rupture. Date of incident 12-26-2025. No MIL or warning messages were present. The vehicle has not been inspected by anyone other than myself for this incident. I feel this issue could have resulted in serious injury or death of my entire family and possibly others on the road. The vehicle has not been modified in anyway and is in OEM configuration. We will have to have the vehicle repaired but will document as best we can. I would like to add that after a quick internet search I found this to be a common issue so I was amazed there was no recall on our Tahoe. Thank you.

The high pressure fuel line from the fuel pump to engine sustained a pinhole leak over the fuel tank. Fuel leaked over top of tank and ran down front drivers side front of tank. Discovered the leak after noticing strong fuel odor inside vehicle. Took to shop. The fuel line is installed as so it will rub undercarriage of vehicle. This is what happened to mine. This is a factory install and the lines are doomed to fail because of this. The excessive contact rubs holes into the lines. This seems to be a common problem with the 2015, according to my research. There are hundreds of these same complaints with this year listed all over repair sites on the internet. I believe this needs looked into, as flammable fuel leaking suddenly can be a hazard.

Starting on August 13, 2022, my 2015 Chevrolet Tahoe exhibited a harder than normal start condition prior to a drive of approximately 80 miles home from visiting a relative. The car drove normally on that trip. After that return home I parked the subject vehicle in the garage and emptied it of my belongings. I noticed a fairly strong gasoline smell and inquired with my wife if perhaps she had re-fueled our other vehicle and experienced any over fill. Shed said no, so I left the garage open to see if it would air out of the fuel smell. It did through the course of the afternoon so I closed the garage that evening. The next morning (August 14, 2022) we had an event to get to in the morning and were planning to take the subject vehicle. The vehicle again had a hard start issue and within 10 seconds of starting I could smell fuel while inside the vehicle with the windows up. I immediately stopped the ignition and looking under the subject vehicle. I saw gas flowing down the side of the fuel tank from above and dripping on the floor at a rapids rate of 2-3 drops per second. This continued for about 5-10 minutes gradually slowing down since the the ignition had been shut off and as the fuel pressure in the system was reduced. By the end there was a puddle of fuel about 1 ft in diameter on my garage floor under the vehicle. From that point and after any strong gasoline vapor smell had subsided, I decided the vehicle needed to be moved from the garage and parked on the street. I parked it on the street and decided I would take it to Marty Feldman Chevrolet immediately early in the morning of August 15, 2022, while roads were less busy. There was no warning light or indication prior to the leak. In some quick research, I found several concerns related to fuel line abrasion and fuel pump leaks/failures. Marty Feldman Chevrolet diagnosis/repair costs are documented in this complaint. Components are available for inspection.

started to notice a fuel smell/odor, which after several days 3 to 4 got worse, then my tahoe started having problems starting, i then seen fuel leaking from the driver's side behind driver's door and below driver's side passenger door, which is where my granddaughter's car seat is located, i inspected where the leak appeared to be coming from, i could tell it was coming from on top of the fuel tank running down the side of the tank leaving a puddle of fuel, the repair shop said they believe the leak is coming from the fuel line and would pull the fuel tank down and replace the fuel line which is going to be a expensive repair. this is a serious safety hazard and should be covered by general motors corporation, i am concerned that my tahoe could have caught on fire while driving without no warning indicator light. i will keep invoices from repair shop and the faulty factory fuel line. i fear this problem could very well cause loss of life or a very serious accident while driving that i believe general motors is aware of.

Noticed a strong gas odor when exiting the vehicle. Upon looking the at the vehicle from top to bottom I discovered that there was gas dripping from the gas tank. Took the vehicle to the dealer, and was told that a fuel line on top of the tank was cracked and needed to be replaced. Since this seemed like a pretty serious safety issue I did some online research hoping to discover a recall, but didn't find any open ones. What I did find was a lot of people saying that this same issue had happened to them, and is a result of a design flaw where the fuel line on top of the tank is too close the the chassis and over time vibrations wear a hole into the line. Since this is such a serious safety issue I feel that that it should be taken care of by the manufacturer.
