# Service bulletins for the 2023 Tesla Semi

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.

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

- [SB\-26\-32\-001](/bulletins/11028089.md), 2026-02-03, Service bulletin: STEERING. On some Semi, the steering gear to reservoir return hose clamp may have loosened over time which may cause steering fluid leakage from the reservoir. Inspect the vehicle for symptoms related to the condition. If symptoms are present, replace the steering gear to reservoir return hose clamp with an updated part.
- [SB\-25\-39\-001](/bulletins/11021495.md), 2025-08-05, Service bulletin: POWER TRAIN. Updated oil pumps that provide improved oil flow are available for the Torque Drive Unit \(TDU\) and Efficiency Drive Unit \(EDU\) on Semi. Replace the TDU and EDU oil pumps with updated parts.
- [SB\-25\-17\-007](/bulletins/11020191.md), 2025-07-04, Service bulletin: VISIBILITY/WIPER. Some Semi trucks are equipped with a windshield washer nozzle that may not meet Tesla specifications. While adequate in suppling washer fluid to the windshield, affected washer nozzles may restrict washer fluid output and increase the amount of wiper cycles needed to remove debris and contaminates.
