2007 Lexus GS430

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 GS430.

Body PASSENGER CARTransmission Automatic (S6)

The 2007 Lexus GS430 is a passenger car fitted with a six-speed automatic transmission (S6) returning EPA fuel economy of 16 mpg city, 23 mpg highway, and 19 mpg combined, with routine service requiring 5.5 quarts of 5W-30 API oil. While the model line’s 2000–2004 production years generated minimal owner feedback—registering between one and five complaints annually, peaking at five in 2003—the 2007 model year accumulates 83 complaints and seven recalls, with air bags representing the top reported concern. This positions the 2007 vintage as a distinct outlier from that earlier low-complaint trend, carrying the highest complaint and recall volume in this surveyed lineage.

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; 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.

Across the early years of this generation (2000-2004), the federal record demonstrates a favorable trend of minimal complaints (peaking at just 5 in 2003), zero recalls, and gradually declining technical service bulletins. In stark contrast, the 2007 model year falls on a troubling upward arc, registering 9 complaints each for Air Bags, Engine, and Vehicle Speed Control, plus 7 for Exterior Lighting. The 2007 GS430 also accounts for 13 crash complaints and 1 fire complaint, a dramatic volume increase over the early generation's single-digit totals. While the data does not specify the root causes for these failures, their concentration implies the 2007 model introduced notable vulnerabilities not present in the preceding years. Given this abrupt departure from the generation's historically quiet record, this is not a recommended model year to buy without thorough pre-purchase inspections specifically targeting the airbag, engine, and speed control systems.
