My wife called me and said she could smell gasoline in our 2015 suburban. I went to the store she was located at and it smelled like raw gasoline. I called a tow truck company and to haul our suburban to the shop. The fuel line has been rubbing against the vehicle frame and rubbed a hole in it. This is very dangerous as the fuel take and line is located right underneath my kids seats.

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.

While driving, I noticed a significant smell of gas coming from my 2015 Chevrolet Suburban. When I stopped the vehicle, it was even more noticeable. I pulled over and got out of the car only to notice gas pouring (not dripping, more gushing) from under the vehicle between the driver's side door and driver's side passenger door. I was concerned as I had my young child with me and had no way of having someone pick us up. I drove it directly to the mechanic in which they confirmed a leak coming from above the tank and that they would not be able to repair the leak until they dropped the tank. Once dropping the tank, they found a hole in the fuel supply line above the tank due to a poor design and friction from the poor design. There is a service bulletin, 17-NA-304, but it does not protect owners from the cost of the repair. The repair cost was $425.38 despite it being a known issue with GM. This design is incredibly dangerous. Not only is the raw fuel inhalation through the vents a health hazard, it could cause a catastrophic fire as well. I have four children, the reason why we needed to drive a Suburban. The devastation of the risk of this flaw is incredible. This needs to be considered a recall and the cost should be covered by the company, not the owner. I emailed GM's customer service and they stated that nothing could be done because the vehicle was out of warranty.

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.

While I was driving approx 45 -60 mph I smelled gas, I dismissed it thinking that I was smelling the old truck in front of me. I parked my Suburban at my destination and still smelled it but I dismissed it because I was late to my appointment. When I came back out to my vehicle approx 2 hours later I still smelled the gas pretty strong. I looked underneath and didn't see any drips, I was parked on grass so I couldn't see any puddles if there was any. I got in and drove approx 100 yards to pick up my son in the parking lot and still smelled it, I shut the vehicle off and looked under, there was a drip about every second coming from the bottom of the fuel tank and it looked like it was coming from the top of the tank where I couldn't see. I took it to Eagle Buick GMC in crystal river and they said it was the 2 fuel lines on the top of the fuel tank. It was approx $680 to fix. While I was waiting for the vehicle I did some research and found that this is pretty common and is due to a design flaw. The gas lines rub against the chassis and get a hole in them. I do believe this is a safety issue and should be a recall.

Gas line or tank is leaking and there is a recall for this on Chevy Suburban, but a recall for this is not listed with my VIN. This is a safety hazard and I should not be required to come out of pocket for this when it is a known issue for vehicles in this class. I started the engine yesterday morning and noticed a gas smell. When I backed out of the stationary spot I noticed gas on the driveway.

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.

28 June took truck in for routine oil change and have cabin filter replaced @ 84K. Less than 24hrs later started driving on hwy and smelling strong odor of gas coming in through my vents thought maybe its exhaust from another vehicle. After parking the truck for a few days I got back in my truck late 3 July and smelled a strong odor of gasoline in the truck and along the outside. 4 July my husband looked under vehicle and took a picture. The smell of gas was not occurring prior to vehicle being serviced and as I keep reading online several other complaints have been filed for this exact thing. This is an extreme danger especially since I have 4 children and this is our daily vehicle. This vehicle could easily catch on fire or cause death due to inhalation. There should be a recall or safety advisory issued for both the 2015 Suburban and 2015 Tahoe as this is a known issue. Chevrolet corporat has been notified case number [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Check engine light comes on due to intermittent high-pressure fuel pump leak. While GM has recalled some vehicles for this problem under recall sb-10057680-1621, bulletin, 14858. GM is not covering the repair, even though the issues match the recall for similar model year vehicles. The light came on while the vehicle was driving.

We noticed a strong fuel smell from our vehicle. When we moved it we noticed a puddle below the drivers door and rear door. Upon inspection it appeared to be a consistent drip of fuel. Our dealer reports that there is a break in the pressurized fuel line which is located above the gas tank. From our review of internet complaints from other owners, this appears to be a product defect in the 2015 Suburban.
