2015 Chevrolet Suburban: fuel leak

Filed Apr 21, 2026 · Fuel system · ND

Fuel line leak caused by design flaw in which line plastic fuel feed line (GM part #84200271) is installed too close to the undercarriage, causing it to rub against the frame due to vibration and wear a pinhole. This is known by gm in service bulletin Service Bulletin 17-NA-304. This is a fuel leak, that can causes significant fire danger to people, property, and nature. Eventually putting first responders at risk. Also the environmental risk of continuous leaking fuel. Luckily, I could smell it before anything bad happened. But if GM knows about this issue, it’s big enough they should do something about it and so should the federal safety agency.

We smelled gas inside and outside of the car. Upon inspection, I found gas leaking from the fuel line under the vehicle that comes from the fuel tank. This created a dangerous situation as noxious fumes were introduced to the cabin of the vehicle, and the leaking gas created a fire hazard. We took the vehicle to the dealer, and they confirmed that the frame rubbing on the fuel line created a dangerous leak. They confirmed this is a common problem for this model and a redesign of the replacement fuel line would prevent the problem in the future, but no recall has been issued. We paid $1180.20 to have the fuel line replaced. No inspections other than the dealer and myself have been performed. No warning lights or messages indicated the problem.

Due to a faulty design, the fuel feed line (GM part # 84200271) has been worn through from vibration resulting in a pin hole in the line at the point where the fuel line is seated in the molded-in clip retainer of the fuel tank. This wear has resulted in raw fuel pouring over the top of the fuel tank and producing a significant risk to life and health from fire and inhalation. The fumes from the raw fuel could be smelled through the A/C vents while driving highway speed (inhalation hazard). Once the vehicle is turned off the fuel leak subsides. However, while idling in park the fuel leak would puddle under the vehicle resulting in a significant and potentially catastrophic fire hazard. While researching the symptoms of my issue, I discovered many complaints of the exact symptoms and findings that I have discovered. I spoke over the phone with a service department employee of a local GM dealership who denied having addressed this issue on other vehicles similar to mine (2015 Suburban LT). I will bring the worn-through fuel feed line to this same dealership to inquire about possible mitigation for this known issue (See service bulletin 17-NA-304). The symptoms that I first noticed were a hard start and the smell of raw fuel in and around the vehicle. No check engine light or other warning messages were displayed to alert me of this failure.

We had just completed a 1,000 mile trip for a family emergency. When we arrived at our destination, we found that somewhere during the last 500 miles of the trip, we had developed a fuel leak. After removing the fuel tank, my husband discovered a break in the fuel feed hose, as well as several worn spots in the line and on the top of the fuel tank. We were traveling in 100 degree weather, and I am just thankful at this point that the Suburban did not catch on fire!

We experienced a massive fuel leak from the top of the fuel tank. The car was still able to run, but there was fuel draining all over the place around the bottom of the car. My wife drove the car with our four kids in it for about 50 miles before we knew what was going on.

2015 chevy suburban. Starting my car the morning of 19 aug 20 I found it odd that it struggled to start. Arrived at work and noticed a strong fuel smell, didn't think much of it, maybe the car next to me. I leave work, and it struggled again. Thought I should look a little when I got home. When I arrived it smelled strongly of fuel again. Upon the inspection of my vehicle, I found the fuel leak. The fuel tank is completely soaked in gasoline. I take it to my trusted mechanic to have a better look and he informed I have to replace the hose in the fuel line above the gas tank between were the two doors meet. Part no. 23248011. It was stationary when I suspected something but evidence suggest the line was rubbed against other components in the undercarriage and damaged the fuel system while in motion. Probably from the other complaint I'm about to put in about the dreaded highway vibration between 75-80 MPH. And that's not speeding, there are highways in texas up to 85mph and tollways at 75mph. A little inconvenience of vibration isn't much of a concern. At first. Fuel however is a major safety concern. This needs to be addressed.
