Service bulletin SB-26-40-001
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 Cybertruck vehicles, the halfshaft bolts may lose torque, which may cause a loud grinding noise if the hub and axle facespline teeth become unseated and damaged. Replace all 4 halfshaft bolts and run a Double Pedal Torque Test to confirm the hub and halfshaft facespline teeth are properly seated.
