Reliability, what owners report, and what it costs to keep.
AVOIR's read: the numbers are mixed and the complaint record is worth reading before you commit.
Owners have filed 172 complaints with NHTSA about the 2010 Toyota Sienna, and it carries 8 recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

NHTSA lists 8 recall campaigns for the 2010 Toyota Sienna. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2005-2007 and 2009-2010 Toyota Sienna vehicles. In the affected vehicles, due to a problem within the shift lock assembly, the shift lever may be moved out of the 'Park' position without depressing the brake pedal.

What stands behind each score for this car:
Owners have filed 172 complaints with NHTSA for this model-year, and structure is the most reported area with 42 of them (24%). There are 8 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 56/100 (average) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 72/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2010 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 68/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
Sources: NHTSA recalls and complaints, EPA fuel economy, IIHS awards, and live market listings. A score describes a model-year, not the individual car in front of you. Get a pre-purchase inspection.
