Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2000 Subaru Legacy shows 103 complaints, 4 recalls, and 0 investigations—figures that represent a stabilization after the elevated complaint volumes of 1997 (146) and 1998 (124), though still marginally above the 1999 low of 98. However, the 93 TSBs recorded for 2000 is striking: this is more than double the 43 TSBs in 1999 and signals a sharp increase in factory-issued technical service bulletins, suggesting emerging issues were being identified and documented as the model matured. The complaint trend then improves substantially in 2001–2002 (dropping to 81 and 59, respectively), though recall activity escalates to 8 in 2001 and peaks at 15 in 2003, indicating the manufacturer was addressing accumulating defects through formal recalls rather than consumer complaints. The target year's complaint profile—focused on tires, engine cooling, powertrain, and suspension—is typical of used vehicles in this mileage range and does not reveal a singular defect pattern. The 2000 model year occupies a transitional position: it escapes the high complaint era of the late 1990s but precedes the surge in formal recalls that peaks in 2003, making it a moderately reliable candidate provided a comprehensive pre-purchase inspection verifies the documented TSB items have been addressed.
