these vehicles fail to conform to fmvss no. 124, "accelerator control systems." at low temperatures, excessive friction can occur in the accelerator pedal assembly.
the fuel tank attachment strap fasteners were not properly tightened. the fasteners can completely detach, eventually allowing the fuel tank to sag and the bottom of the tank to strike the roadway.
paint on the wheel mounting surfaces can act as a shim between the wheel and the rotor/drum. as the vehicle is driven, the wheel imbeds into the paint, loosening the lug nut and causing a loss of clamp load.
the engine oil cooler inlet hose may have been installed too close to the steering gear causing chafing. the chafing can eventually wear through the hose's protective sleeve resulting in engine oil leaking onto the engine.
