What 139 owners told NHTSA about the 2017 Chevrolet Suburban 1500

What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel delivery system has failed. Specifically, the fuel lines are leaking at the connection point on the top of the fuel tank. The vehicle and the affected components are currently available for inspection upon request. How was your safety or the safety of others put at risk? This defect poses an immediate fire and life-safety hazard. Because the fuel leaks while the vehicle is powered on, any spark or heat source could ignite the fuel tank, leading to a vehicle fire or explosion. Additionally, the cabin environment has become toxic; the concentration of gasoline vapors is so high that it causes physical illness. One of my children vomited due to the fumes. The vehicle is currently undrivable because the vapors are intoxicating and hazardous to the health of all occupants. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the leak has been inspected, reproduced, and confirmed by an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages (such as a Check Engine Light) prior to or during the failure. The symptoms—specifically a strong odor of raw gasoline—first appeared four days ago. The intensity of the odor and the rate of the leak have increased significantly since the initial onset.

ON MARCH 21, 2019 I WAS IN AN AUTOMOBILE ACCIDENT DUE TO BRAKE ISSUES. I WAS AT A RED LIGHT IN THE LEFT TURN LANE AROUND THE CORNER FROM MY HOUSE. THERE WERE 3 OR 4 CARS IN FRONT OF ME TO TURN LEFT. LIGHT TURNED GREEN, EVERYONE PROCEEDED. THE CAR IN FRONT OF ME PASSED THE CROSS WALK AT THE INTERSECTION, SHE SLAMMED ON HER BRAKES AND DECIDED NOT TO PROCEED. I SAW HER MAKING A SUDDEN STOP, I STEPPED ON THE BRAKE. SINCE WE WEREN'T GOING VERY FAST, MY EXPECTATION WAS FOR MY CAR TO STOP. I FOUND THAT THE BRAKE PEDAL SEEMED TO BE MORE DIFFICULT TO PUSH. INSTEAD THE HARDER I PRESSED ON THE BRAKE THE MORE I REALIZED I WAS ABOUT TO HIT THE CAR IN FRONT OF ME. AT THAT POINT I FELT LIKE I HAD TO SLAM ON MY BRAKES. THINGS WERE HAPPENING SO FAST. AFTER MY VEHICLE BUMPED THE CAR IN FRONT OF ME, I ASKED THE GIRL TO PULL OFF THE ROAD SO WE WOULDN'T BLOCK TRAFFIC. I CALLED THE POLICE TO COME OUT TO TAKE A REPORT. SHE STATED THAT HER VEHICLE ALREADY HAD A HOLE IN THE BUMPER SO MY VEHICLE DIDN'T DO MUCH DAMAGE TO HER CAR. WE BOTH HAD OUR VEHICLES REPAIRED.
