# Service bulletin SB2233005

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.

- Type: Service bulletin
- NHTSA id: 10235001
- Published by NHTSA: 2023\-04\-24
- Manufacturer's number: SB2233005
- Manufacturer's date: 2022\-04\-29
- NHTSA component: ELECTRONIC STABILITY CONTROL:AUTOMATIC \(ASC\); POWER TRAIN

## NHTSA's summary

Some Model Y vehicles were built without a hydraulic control unit \(HCU\) wake\-up wire, and in rare circumstances, braking and stability control related alerts may appear on the instrument cluster and touchscreen during the vehicle power\-on process. Such faults can typically be corrected and the affected functionality restored with a vehicle power cycle.
