Official summary
Techline summary article - if you run across a spark plug that s loose or has blown out of the cylinder head before reaching the first service interval (generally at 105k), chances are it wasn t torqued enough when it was installed at the factory. The consequences of this can be as minor as reinstalling the spark plug to complete cylinder head replacement due to spark plug thread hole damage.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
