If the side marker lights do not illuminate, the vehicle may be less visible at night, increasing the risk of a crash.

The affected vehicles may have been programmed with new software that inadvertently makes the front side marker lights inoperative in conjunction with the parking lights or the headlights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
