The official notice
Defect
On certain vehicles, the 12V auxiliary cable may have been improperly routed. If the wire is improperly routed and pinched by the wheel well cover, the wire may abrade against the edge of the carbon fiber armature and, over time, expose the wire. Contact between the un-insulated 12V auxiliary cable wire and carbon fiber may cause a short-circuit leading to possible electrical arcing. If not addressed, the short circuit and electrical arcing could lead to a fire.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the routing of the 12V auxiliary cable, install a protective corrugated sleeve over the positive lead to both shield the wire from the armature and increase the wire diameter thus rendering improper routing nearly impossible.
