Service bulletin P_230331_TC_EN

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

Dear Dealer / Service Centre / Authorised workshop, We hereby wish to inform you that the new engine ECU calibration dedicated to the model in question is available by download from the P.A.D.S. diagnostic tool (update the tool to the latest version available). The aforementioned operation is considered part of the normal scheduled maintenance required for the vehicle, and must be performed at the same time as other scheduled maintenance operations either during the pre-delivery procedure, for new vehicles, or at the first available opportunity when the vehicle is brought to the service centre, in the case of vehicles that have already been sold and are in use.

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