Service bulletin SB-59

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

On certain 2019 Buses, there is a possibility that the spoiler on the rear cap may not be securely fastened. If the spoiler is not secured it may come off. We orginally had 96 in this service bulletin. Tiffin made production start gluing these in our production line at the time of the service bulletin, but through a communicatio error, only 15 were glued and then they quit. Therefore, we have went back to the last unit of the 96 prior and expanded the recall to where we started gluing again. We have added 178 more units to this service bulletin.

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.

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