2014 Lexus IS250C

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 IS250C.

Body PASSENGER CARTransmission Automatic (S6)

The 2014 Lexus IS250C is a passenger car equipped with a six-speed automatic (S6) transmission, returning EPA fuel economy of 21 mpg city, 30 mpg highway, and 24 mpg combined, with manufacturer-specified service requirements of 6.7 quarts of 0W-20 API engine oil. Within the 2011–2015 model years for which complaint data is recorded, the 2014 sits squarely in the middle with 35 owner-reported complaints — well below the 2011 high of 49 but well above the single complaint logged for 2015, and led by the electrical system as the top issue area. The fact that this 35-complaint total has been registered against zero recalls is itself a notable data point, and when read against the steep decline from 49 down to 1 across the same span, it places the 2014 IS250C at a relatively stable, late-cycle point in the model's reliability record.

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; spark plugs every 60,000 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 model sits at the low‑point of the generation’s complaint and recall curve, dropping from 49 complaints in 2011 to just zero reported complaints in 2014 and cutting recalls from four in 2011–2012 to two in 2014. While the number of Technical Service Bulletins (TSBs) continued to decline (221 in 2014 versus a peak of 283 in 2013), investigations remained constant at one per year throughout the span. Despite the zero‑complaint count, the underlying issue categories for 2014 still include electrical system and air‑bag problems (each accounting for six reports in the broader dataset), indicating that the “zero” figure reflects only filed complaints, not necessarily the absence of defects. Crash‑related complaints numbered six and fire complaints one, modest figures compared with earlier years. Overall, 2014 shows the most favorable federal record in the series, suggesting it is a comparatively strong year to consider for a used purchase, though prospective buyers should still verify any lingering electrical or air‑bag service bulletins.
