# Service bulletins for the 2024 Lexus NX

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.

103 bulletins from NHTSA, as of 2026-10-19.

- [23LD04](/bulletins/11036119.md), 2026-08-12, Service bulletin: ELECTRICAL SYSTEM. TECHNICAL INSTRUCTIONS FOR 23LD04 GPS Antenna May Not Receive Power CERTAIN 2024 Model Year NX250, NX350, NX350H, and NX450H\+
