Service campaign C7054
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
This Warranty Field Campaign describes the recalibration steps for the engine control module calibration which may falsely detect that the engine is not warming up as expected, resulting in false-positive fault codes being reported. This is an update to the previously submitted communication.
