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 1,497 complaints with NHTSA about the 2008 Toyota Prius, and it carries 4 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 4 recall campaigns for the 2008 Toyota Prius. 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 is recalling certain model year 2004-2009 Prius vehicles manufactured August 5, 2003, through March 30, 2009. The affected vehicles have a steering intermediate extension shaft assembly built with metal splines that complete the connection from the steering wheel to the steering gear. These

What stands behind each score for this car:
Owners have filed 1,497 complaints with NHTSA for this model-year, and exterior lighting is the most reported area with 481 of them (32%). There are 4 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 48/100 (below 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 69/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2008 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 65/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
