1
Hybrid System & Batterymajor~100,000-150,000+ mi

While exceptionally reliable, long-term (150k+ miles) degradation of the auxiliary 12V battery or potential for issues with the inverter coolant pump (a known, though rare, historical Toyota hybrid concern) could emerge. Main hybrid batt…

2
Power Sliding Doorsmoderate~60,000-100,000 mi

As with most minivans, the power sliding door mechanisms (motors, cables, sensors) are prone to wear and tear. They can become slow, noisy, or fail to latch properly due to debris, alignment issues, or motor fatigue.

120,000+

High Risk Zone

At this point, larger components *could* begin to show wear, though major failures are still uncommon for a well-maintained Sienna. Monitor for potential hybrid inverter coolant pump issues or eventual (rare) main hybrid battery degradat…
