2009 Lexus GS450H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 GS450H.

Body PASSENGER CARTransmission Automatic (S6)

The 2009 Lexus GS450H is a passenger car fitted with an Automatic (S6) transmission and a 6.7-quart 5W-30 API oil specification, carrying EPA ratings of 22/25/23 mpg. Within the model's 2007–2017 complaint history, the 2009 model year registers as a notably quiet data point, with just two owner complaints, two recalls, and service brakes identified as the leading complaint area. That volume sits far below the 2007 high of 48 complaints and close to the 2012 low of one, positioning the 2009 GS450H among the more stable model years in the tracked reliability record.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 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 federal record shows a clear downward trend in complaints and recalls from 2007 (48 complaints, 5 recalls) through 2008 (22 complaints, 3 recalls) to 2011 (5 complaints, 2 recalls), with investigations falling from 2 in 2007 to 1 each year thereafter. Although no specific 2009 figures are supplied, the target year sits between the 2008 and 2011 data points, suggesting it would likely reflect a continuation of that declining pattern in complaints and recalls. The 2009 model’s top complaint areas were Service Brakes and Engine, each logged once, and there were no crash or fire complaints recorded for that year. Technical Service Bulletins (TSBs) varied across the years, peaking at 293 in 2013 but showing no monotonic trend that correlates directly with the complaint decline. Given the overall reduction in complaints and recalls leading up to and after 2009, the 2009 Lexus GS450H appears to be a comparatively reliable choice, though prospective buyers should verify individual service history due to the absence of explicit 2009 federal data.
