1 Other Fuel System Tank Assembly problem

Failure Date: 04/28/2021

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. 00 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.

3 Other Fuel System Tank Assembly problem

Failure Date: 02/12/2021

Gas line or tank is leaking and there is a recall for this on chevy Suburbans, 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.

4 Other Fuel System Tank Assembly problem

Failure Date: 08/19/2020

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.

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.
