I my Sienna had its 12 volt battery depleted over night with no reason. After it was jump started, literally every single piece of equipment was malfunctioning and producing an alert (hybrid system, brake pressure, RCTA, BSM, AWD, tire pressure and so on). After several restarts of the engine (about 15 min after running engine), all systems went to normal except hybrid drive system, that still asked for maintenance and the tire pressure sensor was still on alert. However I drove the vehicle to a dealership in Maine after the parking brake finally decided to get loose again. These guys told me, they had just the same problem with another 2022 sienna a week before. However, they reseted the errors, and everything worked fine. They had no explanation why two sienna in one week come to their lot with a depleted battery and as a consequence with a malfunctioning hybrid systen. That's very unsatisfying.

During heavy rain exhaust system become dislodged and fell to the road, only hanging on by the engine connection. We had the vehicle towed to the dealership only to be told that is not a warranty issue. They did reinstall it in the rubber brackets. Due to my persistence a warranty claim was opened. There claim was that it hit something as there were marks across the muffler however those were made by dragging on the road until vehicle could be driven off the road. Knowing it was most likely water pressure from the water on the road that lifted the exhaust up and out of the rubber brackets, I wanted this documented. Although if the exhaust system had completely broken off from the engine it would have not hurt our vehicle occupants, any vehicles behind could have been hit.
