2015 Lexus RX350

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 RX350.

Body SUVTransmission Automatic (S6)

The 2015 Lexus RX350 is an SUV equipped with a 6-speed automatic transmission and an engine designed with an oil cooler for 0W-20 viscosity oil, returning EPA fuel economy figures of 18 city, 25 highway, and 21 combined mpg. This specific model year carries 62 total owner complaints alongside a single recall, with its top complaint area categorized broadly as "Unknown or Other." When contextualized within the model's 2004-2019 complaint history, the 2015 RX350 sits on the highly favorable end of the reliability spectrum, registering far fewer issues than the 225-complaint peak in 2007 and remaining remarkably close to the historic low of 26 complaints in 2014, which signifies a period of strong build quality for researchers to note.

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.

The 2015 Lexus RX350 sits at the tail end of the third generation (2010–2015), and the federal data shows a clear reliability maturation within that generation. Complaints peaked at 225 in 2007 and 270 TSBs in 2010, then dropped sharply—2014 recorded only 26 complaints, and 2015 had 62 with just one recall, a notable improvement over the 3 recalls each in 2016 and 2017. While the 2015 model logged 8 crash-related complaints and 3 fire complaints, the data does not specify root causes, and the overall complaint count remains low compared to earlier years. With 189 TSBs—down from 328 in 2013—the 2015 represents a well-sorted, late-cycle version that benefits from years of incremental fixes. **This is a strong year to buy, offering proven reliability with fewer recalls and complaints than the subsequent 2016 redesign.**
