2019 Lexus RX450H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 RX450H.

Body SUVTransmission Automatic (AV-S6)

The 2019 Lexus RX450H carries the model's hybrid SUV formula forward with an AV-S6 automatic transmission, a 0W-20 recommended oil viscosity, and EPA fuel economy of 31/28/30 mpg across city, highway, and combined cycles. Within a model history spanning 2011 through 2023, the 2019 year logged 36 owner complaints against one recall—with service brakes leading the complaint count—placing it closer to the series high of 55 complaints in 2017 than to the single complaint filed in 2023. For a researcher, that mid-pack reliability footprint, paired with the model's documented efficiency, situates the 2019 RX450H as a typical rather than outlier data point in a lineage whose complaint volume has varied substantially over more than a decade of production.

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.

Across the 2011‑2023 span, the RX450H generation shows relatively low recall activity—only two recalls (2016 and 2019) amid consistently one annual investigation. Complaint volumes fluctuate, peaking at 55 in 2017 and dipping to a single complaint in 2023, with the 2019 figure (36 complaints) sitting near the mid‑range of the earlier decade. Technical Service Bulletins (TSBs) have been on a steady decline, falling from a high of 278 in 2013 to just 119 in 2019, indicating that many known issues were addressed over time. The 2019 model’s top complaint areas—service brakes, miscellaneous “unknown or other,” and a mix of electrical and propulsion system items—are typical of the generation’s pattern and do not signal a new systemic problem. With only one recall and a moderate complaint count that aligns with the model’s overall trend, 2019 is a relatively safe year to consider for purchase.
