Service bulletin CPI425524

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

Certain 10R5645, 10R5647, 10R5648, 10R5649, and 20R1834 Reman ECU's were assembled with incorrect parts causing calibration failures and/or issues with not retaining parameters which contributes to failures of calibration not completed, ECMs losing information, not retaining parameters, etc. These failures can occur during initial installation of the ECM or after the ECM has operated on engine for a short period of time. This issue can occur once the ECM is installed, programmed and the Engine is checked for proper run out. Once this procedure is complete and the engine is shut down, it will not restart due to engine parameters not being stored.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
