Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 IS350.
The 2025 Lexus IS350 arrives with an EPA‑rated 20/28/23 mpg and an eight‑speed automatic (S8) transmission. It carries forward the model’s strong reliability record, logging just a single owner complaint—centered on structure—and zero recalls for the year. That single complaint places the 2025 IS350 at the low end of the model’s complaint history, which spans 2011‑2019 and saw a peak of 23 issues in 2011 and a trough of only one in 2017. Consequently, the 2025 version continues the trend of minimal problems seen in the model’s best years.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The federal record traces a clear maturation arc across the 2011–2019 model years, with complaints declining sharply from 23 in 2011 to zero or single-digit annual volumes by 2016–2019, while recalls dropped from 7 to 0–2 and TSBs fell from 247 to 77. Against this backdrop, the 2025 model year registers minimal activity with only 1 Structure complaint and zero crash or fire complaints recorded, continuing the low-complaint trend established in the generation’s later years. The data does not specify recall, investigation, or TSB counts for 2025, so those metrics cannot be assessed against the historical decline. Given the single non-safety complaint and absence of crash or fire incidents, 2025 appears to represent a stable point in the vehicle’s lifecycle, making it a favorable year to buy.
