Service campaign MAS004744 MCL 25-27

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

We have received several reports regarding issues encountered during the execution of FOTA campaign 740, particularly on MC20 vehicles. Initial analysis indicates that these sporadic issues are occurring on vehicles where the final target software has not yet been installed. Please note that some VINs included in CLR 740 require two separate FOTA updates to complete the campaign, as detailed in the VIN list provided in bulletin MAS004603. The second update can only begin after the first update is successfully completed. Additionally, several hours may pass before the second step is automatically triggered. This delay is dependent on vehicle usage and the availability of network coverage.

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.

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