2004 Lexus LS430

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 LS430.

Body PASSENGER CARTransmission Automatic (S6)

The 2004 Lexus LS430 is a passenger car equipped with an S6 automatic transmission and a powertrain specified to use 4.9 quarts of 5W-30 API oil, delivering an EPA-rated 16 city and 23 highway mpg. While the vehicle carries four recalls and 36 total owner complaints with Vehicle Speed Control ranking as the top issue, this model year represents a clear middle ground in the platform's reliability trajectory. Across the 2001 to 2006 model years covered by complaint history, the generation saw its issues drop from a peak of 52 in its inaugural year to a low of 17 by the end, meaning the 2004 model benefits from ongoing refinements yet still shoulders a higher volume of reported problems than the later, more sorted iterations.

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.

The 2004 model year represents a distinct anomaly within the LS430 generation’s federal record, as it registers 36 complaints, 4 recalls, and 100 TSBs—all higher than the 25 complaints, 1 recall, and 78 TSBs recorded for 2003, and exceeding the 26 complaints and 2 recalls seen in 2005. Across the full 2001–2006 arc, the broader trend shows complaints falling from a high of 52 in 2001 alongside zero investigations after that inaugural year and generally declining TSB volume through 2003, yet 2004 interrupts this pattern with the generation’s peak recall count and a sharp rebound in complaints and technical service bulletins. That spike places the 2004 model at the generation’s highest point for federal regulatory activity, though the data does not specify root causes for the increased recalls; top complaint areas include Vehicle Speed Control, Exterior Lighting, Engine, and Air Bags, with 5 crash-related complaints and 0 fire complaints recorded. Because this year carries the generation’s highest recall count and a notable spike in complaints and TSBs compared with 2003, 2005, and 2006, it is not the strongest model year to buy on federal-record evidence alone; prospective owners should ensure every recall is closed, but 2003, 2005, and 2006 each register fewer complaints and recalls.
