Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Debris that falls between truck cab and bed becomes lodged between gas tank and frame and also between tank and rock shield. This debris becomes soaked from rain and snow without any means to flush out or dry out. Resulting in gas tank corrosion and eventual leaks. Gm has remedied this situation on the SUV family but not on the s10 / s15 class pickups. The current 2000 model pickups still use steel tanks whereas the SUV's now have plastic gas tanks. I've reported this to my local GM dealer and the area GM representative to no avail. …”
NHTSA complaint #714291, filed 1999-11“Consumer was driving around and kept smelling gas coming from the vehicle, looked under the vehicle and saw fuel coming from the tank. Saw gas on the ground, and discovered there is a hole on the upper side on the gas tank, and the gas tank started to get rusty. Contacted dealer, and got the vehicle repaired.”
NHTSA complaint #829215, filed 1998-10“Fuel tank began leaking at front seam where tank is pressed togther due to corrosion. Corrosion was further exasberated by lack of drainage holes in plastic fuel tank protective cover which accumulates water and debris.”
NHTSA complaint #755601, filed 2001-12“The fuel tank has been replaced twice because it split open from the bottom. The original fuel tank was replaced in may of 1999. The used fuel tank was replaced in august of 1999. Please provide any further information.”
NHTSA complaint #849532, filed 1999-09“Engine was idling rough and stalling. Gmc feels it's oxygenated fuel maybe contaminated. Gmc isn't sure, this was an assumption based on environment. Parts are being shipped.”
