Official summary

Service Action: N14 Engine Check Timing Chain Tensioner and Timing Chain. The timing chain tensioner applies pre-tension to the timing chain guide rail mechanism. In some cases, the tensioner spring force may be too low. Depending on the severity of the wear, it may lead to a rattling noise when starting the engine cold or when the engine is idling. CAUSE The timing chain tensioner internal tolerances are not consistent.

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.
