Official summary

Noise from the cam chest area possibly accompanied by milky engine oil. Moisture can cause slight swelling in the tensioner causing it to stick in the housing. A vehicle that makes repeated short trips can have this condition because the engine does not reach normal operating temperatures, allowing condensation and moisture to build up in the engine oil.

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.
