Service bulletin TSIB 22-01

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 is an upgrade to Technical Service Information Bulletin TSIB 21-10 issued in January of 2022 which is specific to buses operating in severe duty and or corrosive environments. These bulletins have been issued to recommend interim inspection procedures required every 6000 miles on specifically equipped motor coaches due to global parts shortages and the subsequent delay in available parts to conduct the corrective actions associated with NHTSA Recall 21V-748.

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.
