Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“On a few occasions prior to locating a leak, I noticed a gasoline smell. Finally when filling earlier this month, I saw a lot of leaking coming out of the fuel filler tube, between the metal tube and the plastic cover surrounding the tube. When I got home, I cut off the plastic tube about halfway and found a static wire running the length of the tube. Everywhere, where this wire touched to metal pipe, it was corroded completely through. The static wire is of a different material and was not corroded. Presently I have wrapped the tube with a gasoline resistant tape. …”

“Corroded and leaking fuel filler neck. Foolish design involving dissimilar metals held in contact and surrounded with a conduit which holds water and road salt. Design is destined for failure. Gm has a partial recall for the snow belt. Such a foolish design should be fixed everywhere as it is just a matter of time until failure.”

“Gas filler tube rusted through and gasoline leaked every time I refueled. This was not a small hole. The metal on the whole tube broke down causing fuel to leak and creating a fire hazard. Updated 08/11/11 updated 3/08/2012”

“I was refueling my van and gas started pouring out from the bottom. After looking I discovered the fuel filler neck was rusted thru. The van only has 64k miles. I replaced it myself at this time. There was no collision damage....simply heavy corrosion.”

NHTSA complaint #10445925, filed 2012-01

“For sometime, there was a smell of gasoline when filling this van, which I just attributed to a vapor release when the tank was full. Recently, I notice gas leaking under the van when filling at the gas station. The gas leaks in and around the brake lines. This van is a 2003 Chevrolet EXPRESS 1500 with left hand door option. This is my family vehicle and in researching this problem further, I understand it to be a known problem and a design flaw, where the fuel fill hose rusts. This needs a recall with immediate attention.”
