Service campaign 25LD01
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
The subject vehicles are equipped with a rear motor unit and an HV Floor Under Wire that provide high voltage to operate the motor. Mud, water, or road salt could potentially enter the HV Floor Under Wire connector housing and could cause corrosion over time. Excessive corrosion could cause AM Radio Static during certain driving cycles, or the vehicle may not start.
