2019 Lexus RX450hL

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 RX450hL.

Body SUVTransmission Automatic (AV-S6)

The 2019 Lexus RX450hL is a full-size SUV featuring a continuously variable automatic transmission designated AV-S6, and vehicles equipped with the optional tow package require 0W-20 engine oil for maintenance, a specification that reflects the drivetrain's particular lubrication demands; EPA fuel economy ratings of 29/28/29 mpg (city/highway/combined) position this model among the more efficient vehicles in its class, a notable characteristic for a three-row utility vehicle. With a total of 33 owner complaints logged across all systems and only one recall on record, the 2019 model year represents a relatively trouble-free iteration within the RX model's extended production run, suggesting that any widespread issues were addressed relatively early in the vehicle's lifecycle and that owners during this period generally experienced fewer documented problems than earlier generations, which bodes well for long-term ownership projections.

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 2019 RX450hL shows a notable uptick in complaint volume versus its 2018 debut, rising from 24 to 33 reports while adding the generation's first recall; TSBs remained essentially flat at 28 versus 27. Braking and electrical/propulsion systems dominate the 2019 complaint profile, with "Service Brakes" and "Unknown Or Other" each drawing four reports and combined electrical-brake-collision avoidance categories accounting for five more, though the data does not specify root causes. Ten crash-related complaints were logged in 2019 with zero fire reports. The trajectory suggests the second model year experienced growing pains rather than a systemic defect wave, as investigations stayed at zero and the single recall did not cascade into broader actions. For a buyer, this means the 2019 carries slightly higher documented risk than the 2018 but remains within normal bounds for a new-platform hybrid, provided any open recall is verified complete and a pre-purchase inspection focuses on brake and electrical system function.
