1 Other Fuel System problem

Failure Date: 04/20/2026

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 NHTSA.

Limited ability to move it safely off the road.

3 Other Fuel System problem

Failure Date: 11/01/2022

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.

4 Other Fuel System problem

Failure Date: 07/11/2022

Leaking fuel line from pump to engine. Rubbed on frame and wore a hole in it.

5 Other Fuel System problem

Failure Date: 06/26/2022

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.

6 Other Fuel System problem

Failure Date: 03/25/2022

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.

7 Other Fuel System problem

The break vacuum pump is going out and making vehicle hard to stop and fuel pump or vacuum is leaking gas and smell inside vehicle.

9 Other Fuel System problem

Failure Date: 08/22/2021

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.

10 Other Fuel System problem

Failure Date: 06/23/2021

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!.

11 Other Fuel System problem

Failure Date: 05/07/2021

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.

12 Other Fuel System problem

Failure Date: 06/28/2019

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 9-5347190370.

13 Other Fuel System problem

Failure Date: 06/27/2016

Head gasket improperly installed blew engine and damaged radiator.

14 Other Fuel System problem

Failure Date: 09/21/2015

\the accelerator pedal and brake pedal are separated by 1-1/4 inches. At rest, the brake pedal is about 1/2 inch higher than the accelerator pedal. When depressed, the brake pedal is 1 inch lower. It is very easy to move your right foot from the accelerator to depress the brakes and not be far enough over to avoid also depressing the accelerator at the same time. There is 4 inches of space between the accelerator pedal and side of the car body on the right side. This is plenty of room to relocate the accelerator pedal to the right, perhaps so that there is the width of a man's shoe sole between the two pedals.

15 Other Fuel System problem

Failure Date: 10/16/2014

The vehicle had approximately 3500 miles when returned to dealership. The primary issue was "running rough. " the vehicle was in the repair shop over five weeks. In three incidents picked up the vehicle when it was supposedly fine. Within minutes the cecile stalled and starting to shutter. Warning indicators include engine and transmission system, emission system, stabilitrack stability control system, and antilock braking system. Vehicle unsafe to drive. The 2015 Suburban was newly designed. Repair bulletins were issued. Vehicle recently picked up and still "runs rough. " the vehicle handles differently as it shifts from v4 to v8 (fuel economy design) when slowing. This makes the vehicle handling inconsistent depending what mode it is operating and can be unsafe. Other potential safety issues when raining, the rear camera (backup) is not functional. Also, when starting in reverse, there is an extended period the "computer is loading" and their is no input although your backing up. In essence, the rear backup warning system is not functional.
