Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 1,200 mi; spark plugs every 60,000 mi; coolant at 137,500 mi. The big-interval services (at 137,500 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

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 2013 Subaru Legacy sits within a notable downward trend in consumer complaints and recalls that began after a 2010-2011 peak (150 and 167 complaints, respectively). Complaints dropped from 90 in 2012 to 66 in 2013, while recalls fell from 16 to 12, and this decline continued into 2014 with only 53 complaints and 10 recalls. However, TSBs jumped to 493 in 2013—the highest level in the dataset to that point—suggesting intensive manufacturer attention to technical issues. The top complaint areas were engine (15), air bags (10), and power train (9), with 6 crash-related complaints and no fire complaints recorded. This positioning suggests 2013 benefits from the post-peak correction in reliability issues while still being early enough in the generation to have received substantial manufacturer focus. The 2013 Legacy represents a relatively safe purchase within this generation, though the elevated TSB count warrants verifying that all relevant service bulletins have been addressed on any specific vehicle.
