Official summary
Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0300 and/or P0316 stored in the powertrain control module (PCM) (with no other relevant DTCs present) during a cold start after a 3 to 8 hours cold soak. This may be due to the machining surface of the intake ports in the cylinder head.
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.
