Service bulletin TSB-048

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

Variation in the PRD bracket mounting hole location in the cross member may result in the PRD assembly installation height being too high resulting in contact between the roof panel and PRD inlet pipe. A revised bracket allows adjustment of the installed height of the PRD assembly.
