Three problems related to tank mounting have been reported for the 2000 Chevrolet Silverado. The most recently reported issues are listed below.
The contact owns a 2000 Chevrolet Silverado. The contact stated that the rear upper shock mount and the fuel tank shocks were corroded, causing the fuel tank to become unstable. The vehicle was taken to an independent mechanic where it was diagnosed that the upper shock mount needed to be replaced. The failure was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was unknown.
Noticed fuel tank strap hanging from underneath vehicle. Upon inspection of fuel tank strap noticed that the strap had rusted & separated about four inches from the bolt mounting location. Fuel tank did not fall to the ground but probably would have if I kept driving it. Noticed that gm uses a rubberized coating on the strap. Water & moisture were able to migrate into the top area of the coating and sit between the rubber coating and the strap & not have any exit point. This caused a moist environment and over time accelerated rust/corrosion between the rubber coating & the steel strap. Poor design & serious safety issue. Pictures are available (can't copy into this form). Multiple similar complaints found on the internet.
Contact stated that one of the gas tank straps that secure the tank to the vehicle rusted. The sending unit was not working properly in showing how much gas was in the tank. The contact looked under the vehicle to see if a wire was loose and found the strap rusted. Dealer ordered a replacement part at consumers expense. Manufacturer has not been contacted yet. When the consumer went to replace the gas strap, he noticed the other strap was in the process of breaking. Updated 11/29/05.
