2017 Lexus RX450H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 RX450H.

Body SUVTransmission Automatic (AV-S6)

The 2017 Lexus RX450h is a hybrid SUV pairing an Automatic (AV-S6) transmission with an engine specified to use 5.7–5.8 quarts of 0W-20 oil, and it returns EPA fuel economy of 31 city, 28 highway, and 30 combined mpg. Those efficiency figures underscore the model's positioning as a fuel-oriented utility vehicle within the SUV body style, where its combined rating remains a defining data point. From a reliability standpoint, however, this particular model year stands as the peak of the RX450h's complaint history covering 2011 through 2023, logging 55 owner complaints—the most of any year in that range—despite recording zero recalls and listing "Unknown or Other" as its top complaint area. That disparity is meaningful context for any researcher: the 2017 high contrasts sharply with the model's 2023 low of just 1 complaint, suggesting the elevated count may reflect how issues are categorized rather than a clear pattern of mechanical failure.

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 2017 model registers the highest complaint count (55) across the 2011‑2019 span, while its recall count returns to zero after a brief spike in 2016 (2 recalls). Compared with the surrounding years, 2016 and 2019 are the only other years with any recalls, and the overall trend shows complaints fluctuating between the low‑teens and mid‑thirties, making 2017 an outlier peak. Technical Service Bulletins (TSBs) continue a downward trajectory, dropping to 199 in 2017 from a peak of 278 in 2013, indicating that while complaints rose, the manufacturer was addressing issues through service information rather than formal recalls. The top complaint categories in 2017 are “Unknown or Other” (12), “Service Brakes” (8), and “Engine” (6), with nine crash‑related complaints and no fire complaints, suggesting the elevated volume is not dominated by safety‑critical failures. Overall, the data imply that 2017 experienced a spike in reported issues but no corresponding increase in recalls, and the decreasing TSB count points to proactive mitigation; therefore, the year is acceptable to buy, provided a thorough pre‑purchase inspection focuses on brakes and engine components.
