- [SB2233004](/bulletins/10235000.md), 2023-04-24, Service bulletin: POWER TRAIN; FUEL SYSTEM, GASOLINE; ELECTRONIC STABILITY CONTROL:AUTOMATIC \(ASC\). Some Heat Pump Model 3 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.
