Service bulletin TSB 25-2071

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 article supersedes TSB 21-2405 to update the production fix date. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: * Illuminated powertrain malfunction indicator (wrench) lamp and/or "Shift System Fault" message * DTC U0103:87 stored in the secondary on board diagnostic module (SOBDMC) Some vehicles may also exhibit DTCs U0100:00, U0121, U0140, and/or U0155 stored in the gear shift module (GSM). This may be due to the software in the GSM. *****Model section: built on or before 30-Sep-2021

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