Service bulletin 6

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

A frame stiffening plate was not installed on four early production units of a new design. Some frame deformation was observed on one of these units. Engineering analysis confirmed that the omission of the plate was the cause of the deformation, so retrofit is being made to these units per the uploaded documentation.
