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 2009 Lexus GS350 is not directly represented in the federal data, which begins in 2011; however, the trend analysis reveals a notable pattern. Complaints remained relatively low in 2011-2012 (7 and 1 respectively), then spiked sharply in 2013 to 41 complaints—likely corresponding to the 2009 model reaching its 4-year mark and exiting the warranty period—before declining thereafter. The 2009 model year itself shows 3 crash complaints, all related to Vehicle Speed Control issues, with no fire complaints recorded. Compared to later model years in the dataset (2016-2019), which show minimal complaints (0-4) and improved reliability, the 2009 falls at the beginning of a generation that experienced significant mid-cycle issues. This suggests the 2009 GS350 carries more risk than later examples from the same generation.
