What Sienna owners report across recent generations
Owner summary2021–present (4th generation)
Owner reports are thin for this hybrid only generation. CarComplaints has only a few reports, citing an intermittent brake release and no spare tire on the 2021. A handful of NHTSA owners of the 2021 describe the brakes briefly letting go and the van lurching forward during slow stops. Most 2025 NHTSA complaints concern a recall for third row seatback bolts on 2021–2025 models that may not be tightened properly, and a 2025 recall covers second row seat rails that may be poorly welded.

2011–2020 (3rd generation)
Complaints are moderate and focus on the early years. CarComplaints ranks premature tire wear first for 2011, followed by loose inner tie rods and malfunctioning sliding doors. NHTSA owners of the 2011 describe power sliding doors that fail to latch and long waits for Takata passenger air bag repairs. Recalls cover power sliding doors on 2011–2016 models that may open unexpectedly after being frozen shut and spare tire carrier cables on 2004–2011 models in road salt states that may corrode.

2004–2010 (2nd generation)
Sliding doors are the main complaint area here. CarComplaints ranks split cables on the automatic sliding doors first for 2004, followed by sudden unintended acceleration and a broken weld in the door, and hundreds of NHTSA owners of the 2004 report sliding door trouble. Recalls cover a shift lock solenoid on 2004–2005 and 2007–2009 models that may let the lever leave park without pressing the brake, and corroding spare tire carrier cables. [6] [7]
