On certain vehicles, the spark plug wires may be causing the Malfunction Indicator Lamp (MIL) to be illuminated, as well as causing rough idle and poor performance.

Correction: Dealers will replace all six spark plug wires with a new service spark plug wire assembly kit that is designed to be robust against dielectric breakdown failures.
