GMC C15 complaints by model year
1996 GMC C15 recalls (5)
Fuel system, gasoline › Storage › Tank assembly
Vehicle description: crew cab pickup trucks. The front, inner corner of the fuel tank can contact the body sill either intermittently or constantly. This movement can cause a discernible noise and, over time, can wear a hole in or crack the fuel tank at point of contact.
Remedy: Dealers will inspect the fuel tank for wear and, either install a spacer between the fuel tank and the front crossmember, or if necessary, replace the fuel tank.
Seats
Vehicle description: extended cab and 2-door utility vehicles equipped with reclining seats and the easy-entry feature. These vehicles exhibit a condition in which a pinch point exists in the recliner mechanism that can trap and pinch a person's hand or finger(s) when the easy-entry feature is activated.
Remedy: Dealers will install a protector cover over the recliner mechanism.
Suspension › Rear › Springs › Leaf spring assembly › U-bolt, leaf spring to axle
The four u-bolts nuts on either side of the rear axle were under-torqued.
Remedy: Dealers will check the u-bolt nut torque and re-torque any loose u-bolts to specification.
Vehicle speed control
These vehicles were assembled with the throttle cable contacting the dash mat which could bind the throttle. This does not meet with the maximum return times required by federal motor vehicle safety standard no. 124, "accelerator control systems."
Remedy: Dealers will inspect for adequate throttle cable to dash mat clearance, and if there is insufficient clearance, cut out a portion of the dash mat to provide proper clearance.
Fuel system, gasoline › Delivery › Hoses, lines/piping, and fittings
Certain trucks have fuel rail assemblies with an improperly crimped end retainer clip that results in a fuel leak.
Remedy: Dealers will inspect the fuel rail assembly and replace any fuel rail assembly with a julian date code of 95318 through 95338.
