ISSUE

Some ignition switch lock cylinder assemblies may exhibit the following highly intermittent conditions:

^ Roughness and/or excessive effort in turning the key from RUN to START position.

^ Key does not fully return from START to RUN after starting vehicle. This may result in intermittent accessory function.

^ Continental ONLY - A malfunction indicator lamp may illuminate with diagnostic trouble codes P0500, P1502 and UlO3g stored in the Powertrain Control Modules (PCM) memory.

This may be caused by a Key-In-Ignition warning chime switch.
