The 2025 Toyota Highlander belongs to the 4th generation (XU70) (2020-present), built with 3.5L V6 (2GR-FKS, 2020-2022) or 2.4L Turbo I4 (T24A-FTS, 2023+) with an 8-speed Direct Shift automatic; 2.5L Hybrid I4 (A25A-FXS) with a hybrid transaxle, all years - the base 2.7L I4 was discontinued for this generation. It takes 0W-20 full synthetic (V6 and Turbo); 0W-16 full synthetic (2.5L Hybrid, new spec for this generation). Oil changes run 10,000 miles or 12 months normal duty; 5,000 miles under severe duty. This sits in the middle of the generation run, generally the most sorted point in a design before end-of-run cost reductions.
A 2025 Toyota Highlander is a year old in 2026, which at an average 12,000 miles a year puts it around 12,000 miles - still under warranty. At roughly 12,000 miles this vehicle is still early enough to be inside the range most manufacturer warranties cover. The most valuable thing you can do this early is start a service record - it is worth real money at resale and it is nearly impossible to reconstruct later. The next milestone on its own schedule is 30,000 miles, roughly 1.5 years away at average use, listed as: Replace cabin air filter, Replace engine air filter, Inspect automatic transmission for signs of leakage (all engines, including the Hybrid transaxle - no fixed replacement under normal duty), Replace rear differential fluid, Replace transfer case fluid.
The fault most worth knowing about on this generation is First-model-year risk on the 2.4L Turbo (2023) - limited multi-year fleet history as of this pass. Owners also report Direct-injection engines (2GR-FKS, T24A-FTS) require a brake-booster vacuum pump that the Hybrid does not have; and 12V auxiliary battery drain on the Hybrid if left unused for extended periods - separate from the HV pack. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
