Body PASSENGER CARTransmission Automatic (S8)

The 2014 Lexus IS350 is a passenger car powered by an engine requiring 6.7 quarts of 0W-20 API oil and mated to an eight-speed automatic transmission, carrying EPA fuel-economy ratings of 19 mpg city, 28 mpg highway, and 22 mpg combined. Within the model’s 2011–2019 complaint history, the 2014 model year recorded 14 total owner complaints, a figure that sits between the high of 23 set in 2011 and the low of 1 recorded in 2017.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 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.

The 2014 Lexus IS350 occupies a notable position in its generation’s reliability arc, reflecting a clear downward trend in federal complaints and recalls compared to earlier model years. Complaints dropped sharply from 23 in 2011 to just 8 in 2013, before rising modestly to 14 in 2014—still well below the generation’s early peak—while recalls fell to just one, the lowest since launch. This suggests Lexus addressed many initial quality concerns by 2014, though the slight uptick in complaints (primarily tied to the fuel/propulsion system and steering) indicates lingering but isolated issues. The data shows a generation-wide improvement in dependability, with 2014 positioned as a transitional year: better than the problematic 2011–2012 models but not yet as refined as the nearly complaint-free 2015–2017 models. With no fire-related complaints and minimal crash reports, the 2014 IS350 appears to be a relatively safe and stable choice—**a good year to buy, provided a pre-purchase inspection confirms the fuel system and steering components are in order.**
