The loss of low beam headlamp illumination will decrease the driver's visibility, as well as the vehicle's conspicuity to other motorists, increasing the risk of a crash.

In the affected vehicles, the underhood bussed electrical center (UBEC) housing can expand and cause the headlamp low beam relay control circuit wire to bend. If the wire is repeatedly bent, it may fracture causing a loss of low beam headlamp illumination.
