Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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.

Across the provided federal record, the Prius experienced a significant spike in complaints in 2010 (2,819) followed by a general downward trend in reported issues through the mid-2010s. The 2014 model falls within this improving arc, recording 233 complaints, which is a notable decrease from the 399 reported in 2013 and 682 in 2012. While it shares the same number of recalls (3) and investigations (3) as the 2013 model, its 477 TSBs are higher than the 324 recorded for 2015. The primary complaint area for 2014 is Service Brakes with 68 reports, though the data does not specify the root cause for these or the 18 "Unknown Or Other" reports. Given the steady decline in complaints from previous years and relatively low recall volume, the 2014 is a good year to buy.
