Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
NHTSA complaint #11415817, filed 2021-05, 134,000 miles“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.”
