Mislocated welds securing the upper front suspension arm mounting brackets to the frame. The mounting bracket could break off during riding, reducing rider control and resulting in loss of control of the ATV. Loss of control could result in a crash and severe personal injury or death.
Some of the ATVs were assembled with a wire harness that may have broken ground wire strands from an improperly crimped wire splice. Broken ground wire strands could result in electrical open circuits. An electrical open circuit could prevent the tail/stop lamp from illuminating or could cause the CDI-unit of the ignition to not function. If the CDI-unit does not function, the engine will stop running, possibly leaving the rider stranded away from his or her base of operation.
The nut that secures the LT-F400K2 and LT-F400FK2 clutch shoe will come loose during operation. When the nut loosens, the clutch shoe will become loose on the crankshaft. In some cases this will cause severe damage to the clutch wheel and crankshaft or can cause the crankshaft to break. This will interrupt power transfer from the engine to the transmission and the drive wheels and may leave the rider stranded away from his or her base of operation.
