Service bulletin SB-52

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

Some of the awning wires were not properly terminated on some 2016 45OP Allegra Buses. The specific wires only have power on them when the awning is being opened or closed. If this wiring is not corrected, some damage to the awning's circuit board could result.

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