Service bulletin NCU-2020060009

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

The software for the transmission control unit on the above model series vehicles transferred to you does not correspond to the current series production configuration. Because of this, the transmission may not shift beyond third gear when in automatic drive program D. Manual shift operation beyond third gear is still possible using the paddle shifters.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Components

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