Open the full vehicle complaint log (all categories)The failure is believed to have originated in the fuel delivery system, specifically the check valve in the low-pressure fuel feed jumper line at the engine. This valve failed to seat properly, allowing high-pressure pulses to travel back into the low-pressure side of the system. This malfunction caused the S-shaped portion of the fuel feed line near the tank to vibrate excessively against its mounting clip. This constant friction wore through the line, resulting in an active fuel leak. All damaged components remain on the vehicle and are available for inspection upon request. The safety of the driver, passengers, and the public is at immediate risk due to a severe fire hazard. Because the leak is located near the fuel tank and undercarriage, gasoline is being released where it could be ignited by road sparks, static electricity, or exhaust heat. A fuel leak of this nature threatens a catastrophic fire that could result in vehicle loss or personal injury. The problem has been confirmed via a physical inspection that matches the symptoms documented in a GM Service Bulletin (Recall - High Pressure Fuel Pump Leakage). While the vehicle has not yet been subjected to a formal tear-down by a dealer due to the danger of driving it with a leak, the visual evidence at the exact location specified in manufacturer documentation confirms the failure. To date, the vehicle has not been inspected by the manufacturer, police, or insurance representatives. Prior to the leak, the primary symptoms were an audible rattling and ticking noise from the engine bay and underside, characteristic of the pressure pulses described in the TSB. There were no warning lamps or dashboard messages, as the mechanical wear on the exterior of the fuel line occurred outside the scope of the vehicle’s onboard diagnostic sensors.
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.
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.
Fuel line leak. After researching it appears there was a safety recall for this in the 2015 Chevy Tahoe.
I’ve had to have the fuel line replaced 3 times because of fuel leaks.
Fuel pouring from underneath the truck

The contact researched and discovered TSB: 17-NA-304; however, the contact was informed that the repair could not be covered under the TSB. The failure mileage was approximately 220,000.
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

The vehicle was taken to a dealer where it was diagnosed with a high-pressure fuel pump leak. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 19V837000 (Fuel System, Gasoline) however, the model year was not included in the recall. The dealer confirmed that the vehicle was not included in the recall. The manufacturer was made aware of the failure and also confirmed that the vehicle was not included in the recall. The failure mileage was approximately 65,000.
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 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.
The contact owns a 2015 Chevrolet Tahoe. The contact stated that she would smell the odor of gasoline when she approached the vehicle.

Gas leaking out of my vehicle. First noticed it right after pumping gas then started smelling a strong odor of gasoline!
The contact owns a 2015 Chevrolet Tahoe. The contact stated that after refueling the vehicle, an abnormally strong fuel odor was detected.

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