2020 Toyota Sienna: power train leads a small set of owner complaints

Owners filed 35 complaints with NHTSA, a relatively low count. The power train is the most reported area at 23%, followed by a three-way tie among the engine, fuel/propulsion system, and electrical system at 17% each. No crashes, injuries, or deaths are reported. Two reports mention a fire (one engine, one fuel/propulsion system), so those areas are worth a closer look.
