Service bulletins for the 2023 Volkswagen ID.4

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.

321 on file from NHTSA, as of 2026-10-19.
