2011 Lexus RX450H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 RX450H.

Body SUVTransmission Automatic (AV-S6)

The 2011 Lexus RX450H is a hybrid SUV built on the RX platform, powered by a hybrid powertrain paired with an automatic AV-S6 transmission and rated by the EPA at 31/28/29 mpg city/highway/combined; routine service calls for 6.4 quarts of 0W-20 API engine oil. Within the 2011–2023 RX complaint record, the 2011 model sits near the lower end of reported issues, with 36 owner complaints and zero recalls, suggesting a relatively quiet early chapter for this generation. The top complaint area is the engine, though that should be read against the broader trend that saw complaints peak much later, at 55 in 2017, and fall to just one by 2023.

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 2011 Lexus RX450H recorded 36 consumer complaints, which is above the low points seen in 2012 (14) and 2014 (13) but below the peaks in 2013 (31), 2016 (34), and especially 2017 (55). It had no recalls, matching the recall‑free record of most years in the dataset except for 2016 (two recalls) and 2019 (one recall). An open investigation was noted for 2011, a pattern that persisted annually through 2019 before dropping to zero in 2023. Technical service bulletins were relatively numerous at 254 for 2011, reflecting a higher volume of service guidance than the later‑year decline to as low as 119 in 2019. Overall, the 2011 model sits in the middle of the complaint trend, with no recall issues, making it a reasonable choice among the generation’s years.
