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.

9100811 Rev 42026-07-02. Service bulletin. Clunking when going over bumps, potholes, or turns. During diagnosis dealers may find rubber separating from the bushing on the handling link (SOL S2102000004 Rev C. for reference). This is normal and most likely is not attributed to the noise. Please follow normal diagnosis and ensure all tie-rod and ball joints are properly torqued and if worn, replace. If diagnosis leads to lower control arm replacement, the tension link(s) should be replaced first then test driven to ensure noise has disappeared before any handling link replacements.
