Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 IS300.
The 2025 Lexus IS300 arrives equipped with an eight-speed automatic transmission and EPA ratings of 21 mpg city and 31 mpg highway, representing the latest iteration of a nameplate that has generated owner-reported data since 2001. With zero recalls and only a single complaint lodged to date—specifically regarding structure—the current model year sits at the favorable end of a reliability spectrum that saw complaints peak at 45 units in 2002 before dropping to just two by 2017. This progression suggests the platform has matured significantly from its early production years, offering researchers a vehicle with documented historical volatility followed by sustained improvement.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The federal record for the IS lineage shows two distinct arcs: the first generation (2001–2005) started with elevated complaint volumes—35 in 2001, peaking at 45 in 2002—before tapering to 16 by 2005, with recalls present every year. The current generation, represented by 2016–2019 data, shows a dramatically different profile: complaints dropped to single digits (2–7 annually), recalls were sparse (zero in 2016–2017, then 1–2 in 2018–2019), and TSBs were far more numerous, peaking at 164 in 2016 and declining to 82 by 2019, suggesting proactive manufacturer communication rather than widespread defects. The 2025 model year falls well beyond the last recorded year in the dataset, so no year-by-year comparison is possible for the years immediately preceding or following it; however, the target-year-specific data shows just 1 complaint (in the Structure category), with zero crash and zero fire complaints, which is consistent with the low-complaint trajectory established in the current generation. The data does not specify a root cause for the single Structure complaint, and no recalls or investigations are indicated for 2025. Based on the available federal record, the 2025 IS300 appears to be a low-risk purchase, continuing the generation's pattern of minimal complaint volume and sparse recall activity.
