# Service bulletin SB2233006

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

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.
