2006 Lexus GS300

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 GS300.

Body PASSENGER CARTransmission Automatic (S6)

The 2006 Lexus GS300 is a passenger car that requires 6.7 qt of 5W‑30 API oil and couples its engine to a six‑speed automatic (S6) transmission, delivering EPA‑rated fuel economy of 19/25/21 mpg. Owner feedback for the model year tallies 180 total complaints, with Exterior Lighting cited as the leading problem area and eight recalls issued. Within the GS series’ complaint history from 1993‑2019 — where the yearly peak was 69 complaints in 1998 and the trough was just one complaint in 2013 — the 2006 model’s 180 complaints place it well above the typical yearly range, signaling a less reliable year for the nameplate.

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 2006 model sits between the 2004 year, which recorded 8 complaints and 1 recall, and the 2007 year, which showed 0 complaints but 1 investigation and 1 recall, indicating a low‑complaint environment typical of that period. Across the generation, complaints surged in 1998 (69) then declined steadily, remaining under 20 after 1999 with only occasional spikes and recalls. The 2006 year falls within this low‑complaint phase, reporting 13 crash‑related complaints and 2 fire‑related complaints, consistent with the overall downward trend. Its top complaint areas — Exterior Lighting (30), Engine (14), Visibility/Wiper (11), and Steering (11) — reflect modest but recurring concerns rather than a systemic failure. Consequently, the 2006 GS300 is a reasonable used purchase provided the price reflects its modest complaint history and the vehicle is inspected for the noted defect areas.
