2023 Lexus IS350

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 IS350.

Transmission Automatic (S8)

The 2023 Lexus IS350 is equipped with an Automatic (S8) and EPA ratings of 20 city, 28 highway, and 23 combined mpg, with routine oil service specified at 6.0 quarts of 0W-20 or 5W-20. Reliability data for this model year records three total owner complaints, zero recalls, and structure as the top complaint area, a profile that falls within the broader 2011–2019 historical band spanning a high of 23 complaints in 2011 to a low of 1 in 2017. That placement situates the 2023 IS350 near the low-complaint floor of the model’s documented reliability history, meaning it maintains the same reduced owner-reported issue rate seen in the quietest years of that range.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 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 2023 Lexus IS350 carries an exceptionally light federal complaint footprint, with only three complaints filed across the entire model year — one each in Structure, Visibility, and Power Train — and notably zero crash or fire complaints, which are the categories that most directly correlate to safety risk. When placed in the trajectory shown by the 2011–2019 record for the same nameplate, the trend is decisively favorable: complaints fell from 23 (2011) and 20 (2012) down to single digits by 2013–2014, and then collapsed to just 0–2 per year from 2015 onward, while recalls similarly dropped from a peak of 7 to 0–2 in the later years shown. The 2023 model therefore sits at the mature end of a generation that has clearly stabilized, with no open investigations and complaint categories that suggest isolated quality issues rather than systemic defects. TSB volume, while not reported for 2023 in the provided data, followed a similar downward arc through the prior generation, reinforcing the picture of a well-sorted platform. The data does not specify a root cause for the three 2023 complaints given the small sample, so no recurring defect can be inferred. On the whole, 2023 is a strong candidate year to buy used: low complaint density, no fire or crash reports, and a multi-year trend of improving reliability all point to a well-aged luxury sport sedan.
