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 2015 Lexus IS250C sits at the favorable tail end of a clear improvement arc across the 2011–2015 generation, with federal complaints plummeting from 49 in 2011 to just 1 in 2015, while recalls likewise eased from four to two and TSBs dropped from a 2013 peak of 283 to 168. The single 2015 complaint spans the Power Train, Electrical System, and Wheels categories, and the year carries zero crash or fire complaints, indicating that whatever residual issues remained were neither severe nor widespread. An open investigation persisted across every model year in the data set, suggesting a longstanding but apparently non-safety-critical matter that the data does not specify in cause. Because the 2015 model year posts the lowest complaint, recall, and TSB counts of the entire generation, the trend implies that early-life issues had largely been resolved by the time this convertible rolled off the line. For a used buyer, this profile — minimal owner-reported problems, no fire or crash allegations, and a mature service-history footprint — makes the 2015 IS250C a notably strong year to target within its generation.
