2016 Lexus GS450H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2016 GS450H.

Body SUVTransmission Automatic (AV-S8)

The 2016 Lexus GS450H is an SUV fitted with an Automatic (AV-S8) transmission and EPA ratings of 29/34/31 mpg. Reliability data for this model year counts 34 owner complaints, with structure representing the top complaint area, alongside two recalls. Viewed within the 2007–2017 complaint span, where annual owner reports peaked at 48 in 2007 and fell to a single complaint in 2012, the 2016 model lands notably above that floor, meaning it generated a comparatively elevated volume of reported issues relative to the quietest year in the series.

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 2016 Lexus GS450H occupies a notable position within its generation’s federal record, particularly when compared to adjacent model years. Complaints spiked to 17 in 2013 before dropping sharply to just 1 in 2015, then rising again to 6 in 2016—suggesting a mid-cycle uptick in reported issues, though still far below the 48 complaints logged in 2007. Recalls and investigations remained absent for 2016, mirroring the stability seen in 2015 and 2017, while Technical Service Bulletins (TSBs) declined from 258 in 2015 to 134 in 2017, indicating fewer unresolved technical concerns as the generation matured. The 2016 model’s complaints were concentrated in structure (6), powertrain (5), and brakes (4), though crash-related reports (3) and no fire complaints suggest no systemic safety defects. This year falls in a transitional phase—post-peak TSBs but pre-final refinement—yet its relatively low complaint volume and zero recalls imply a reliable midpoint. **Given the data, 2016 emerges as a sound choice, balancing age with improved reliability over earlier years while avoiding the unknowns of later minor updates.**
