Service bulletin MYCOM_031621-1

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

M2 and SD Scheduling Production Update Through a relentless focus on serving our customers, we have continually adapted to overcome the earliest effects of the COVID-19 pandemic to ensure our ability to deliver trucks and parts for those who keep the world moving. However, just a little over one year after the first effects of the pandemic began to impact global semiconductor supply chains, the prolonged duration of these shortages have now reached our own supply chain en masse.

The document

• NHTSA's copy of the document (PDF)

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.
