The hazard

On certain vehicles, an undersized wire in the trailer stop lamp circuit of the instrument panel harness is susceptible to thermal cycling which may cause damage to the wiring. This could result in the trailer lamp fuse failing, which could cause stop lamps to become inoperative and increase the risk of a crash. This damaged wiring could also increase the risk of fire. These issues could result in injury and/or damage to property. Correction: Dealers will replace the undersized wire in the harness.
