Service campaign S4308 202412
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
Volvo Trucks has identified that certain VN model trucks may encounter an issue with the EECU during a shutdown event. If this occurs, the EECU could become corrupted, leading to multiple fault codes, engine derate, and, in some cases, preventing the truck from starting.
The document
