2015 Chevrolet Tahoe FUEL/PROPULSION SYSTEM

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.

Fuel line leak. After researching it appears there was a safety recall for this in the 2015 Chevy Tahoe.

I am leaking fuel from the fuel lines connected to the fuel tank. I can smell the fumes inside of the cab. I also can see the fuel leaking under the driver seat.

I’ve had to have the fuel line replaced 3 times because of fuel leaks.

The high pressure fuel pump may leak resulting in fuel odor and increased evaporative emissions. The engine may also fail to start or provide less power when driven due to insufficient fuel pressure. Recall came out on February 2015 Bulletin No.: 14858 Part Number: 12626354 Description Intake Manifold Gasket 12618337 Intermediate Fuel Feed Pipe 8/V8 Engine 12625817 Fuel Pump SERVICE PROCEDURE

Fuel line has a hole in it from rubbing against the frame this is the 2nd time I've had to repair the fuel line in the 3.5 years I've had the vehicle

The fuel tank is leaking from the top of the tank.

Gas leaking out of my vehicle. First noticed it right after pumping gas then started smelling a strong odor of gasoline!

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.

Leaking fuel from the in-line on top of gas tank. Very dangerous and alarming that this is a known issue and you choose to set back doing nothing. It’s the same exact problem that everyone is talking about so it’s be nice to be reimbursed for the parts or repair or something

2015chevy Tahoe LT fuel pump rattle cause fuel line to rattle. Service Bulletin Bulletin No.: 17-NA-304 Date: February, 2020 Subject: Brand: Cadillac Chevrolet TECHNICAL Ticking, Rattle and/or Buzzing Noise Heard from inside Passenger Compartment, Possible Fuel Leak Model: Escalade Escalade ESV Model Year: from VIN: Engine: L86 L86 L83 L83 L83, L86 L83, L86 Transmission: to from to Suburban Tahoe 2015 Yukon Models Yukon XL Models 2020 GMC Involved Region or Country North America, Middle East, Europe, Russia, Chile, Columbia, Ecuador and Peru. Condition 1 Some customers may comment on the following condition: • Arattlingand/ortickingnoisethatmaybelouderinsidethevehiclethanoutside. ⇒ The noise may be picked up at the back of the left valve cover, and/or underneath the vehicle near middle of the driver’s door. ⇒ This noise will be noticeable at idle, most noticeable in the 700-900 RPM range. ⇒ The noise may also sound like a lifter tick. ⇒ This may also be called a fuel line buzz or ringing noise. • Whiletherattleisoccurring,theS-shapeportionofthefuelfeedline,rightinfrontof the tank, will be vibrating / rattling. Condition 2 Some customers may comment on a fuel leak. Diagnosis that the fuel leak is originating from the fuel feed line at the molded-in clip on top of tank. Cause The rattling, ticking noise may be caused by the check valve in the low pressure fuel feed jumper line at the engine not fully seating, allowing pressure pulses from the high pressure side back into the low pressure side of the fuel system. These pressure pulses could cause the S-shaped portion of the fuel feed line, in front of the tank, to vibrate and/or rattle If the S-shaped portion of the fuel line rattles over a period of time, the fore-aft motion in the line could result in wear. This wear could result in a fuel leak where the line is secured into the molded-in clip on the tank.

I bought the vehicle from Dan Cummins dealership and a few months later started to smell gasoline got it checked vehicle replaced the gas line it was leaking

The fuel feed hose that tracked on top of the gas tank rubs against a portion of the tank and a pinhole sized hole gets created. Anytime the vehicle is on or fuel pump pressurizes the line, fuel is sprayed all beneath the vehicle. Gm has made a “fix” to the line by adding a shroud to the updated part. Part number 84200271 is the updated part. I contacted Martin Chevrolet in crystal lake Illinois and was advised since my vehicle was out of warranty nothing was covered. Spraying fuel due to bad engeeniering is as unsafe as it gets.

Came home and could smell gas. Had just filled up so ignored it. Next day, just pulling into driveway, husband could see gas pouring out the bottom below the drivers seat area.. fuel line split. Had to have it towed to dealership and paid nearly a grand to get that repaired. Warranty wouldn’t cover it..

Safety Hazard. Fuel feed line is leaking from top of gas tank and running down beside tank, which can lead to vehicle fire or explosion.

Fuel line at tip of gas tank is leaking. I see dozens of complaints online for others who say gas line to close to chassis, plastic and rubbing and causing a leak. I see some caused fires?

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.

Gas leak at line due to rubbing-FIRE HAZARD

WHILE OUT DRIVNG OTHER VEHICLES WAVED ME DOWN TO INFORM ME VEHICLE WAS LEAKING MASSAVE AMOUNTS OF FUEL. I PULLED OVER TO SEE FUEL LEAKING UNDER VEHICLE. THE SMELL WAS STRONG AND IT WAS POURING OUT AT A DECENT RATE.

Fuel smell outside of the vehicle. About 3 months ago one part was replaced. Now the smell is back. Vehicle is at the mechanic so they can investigate further.

The pressure fuel line on top of the gas tank started leaking while driving and caused large puddles of gas under the car. Parked vehicle and unable to drive it due to gas leaking near exhaust.

Fuel supply line coming out of gas tank is leaking. Looked up on internet and found this to be a very common occurrence, with several pictures of Tahoe's sitting on the side of the road on fire. This is such a common issue on 2015 models that GM should recall and fix. We can't wait for a recall, I know that takes a lot of time. The Tahoe is my wife's ability to get to work and home, as she is the breadwinner in our family, I am on SSDI for total disability. We need someone or some organization to step up and assist us in getting this problem fixed and since it is a design flaw resulting in a serious safety issue, GM should be held responsible for the repair. Local mechanic found the problem after wife smelled strong odor of gasoline in garage where vehicle is parked, which happens to be directly below our bedroom, thus if a fire started in garage, with my health and mobility problems, we might not be able to escape. This is a serious problem, common with this model and I'm sure you've heard about it several times, please help us.
