Service bulletin T-SB-0006-21
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
TSB: Some customers may notice an abnormal brake feel in their 2021 model year Sienna Hybrid vehicle that could be described as a longer than usual brake pedal stroke. This may occur when the engine is off for more than five minutes after entering the vehicle and closing all doors before driving. The condition does not affect braking performance and will improve as the system performs learning cycles during vehicle operation. However, once the engine is turned off and the brake ECU goes to sleep, these learned values will be reset and the abnormal brake pedal feel will return. Follow the Repair Procedure in this bulletin to address this condition.
