Service bulletin 18258

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

18258 - Service Update. These vehicles were built without anti-abrasion wrap on the engine wire harness designed to prevent potential wear-through of the wire harness insulation over extended periods of time. If insulation wear-through were to occur, damage to the harness wires may result. Damage to individual circuits may result in diagnostic trouble codes (DTC?s) being set. A service engine indicator may be displayed, and the engine may not start, run rough or run in reduced propulsion mode. Dealers will add an anti-abrasion wrap and sleeve to area of contact.
