The Grand Highlander's maintenance chart is spread across three pages of a 48-page booklet, with different footnotes for gas and hybrid trucks. This page puts it in one table, by mileage, from Toyota's own Warranty and Maintenance Guides.
Where these numbers come from. The maintenance charts in Toyota's 2025 and 2026 Grand Highlander and 2025 Grand Highlander Hybrid Warranty and Maintenance Guides (publication numbers T-MMS-25GrandHighlander, T-MMS-25GrandHighlanderHV and T-MMS-26GrandHighlander). The 2025 and 2026 gas charts are identical. We read the 2024 guide's oil and tire-rotation intervals, which match, but we did not compare its other items line by line. Your own guide governs, and a dealer may recommend more based on inspection.
Every Visit: 5,000 Miles or 6 Months
- Rotate tires at every 5,000 miles.
- Inspect all fluid levels, wiper blades and the brake linings and pads (a visual check each 5,000 miles, thickness and disc runout every 30,000).
- Check the driver's floor mat installation.
- Hybrids: visually check the HV battery cooling intake filter for dirt and dust, and clean it if needed. Toyota says to clean it every 20,000 miles.

| Spark plugs | 40,000, 80,000, 120,000 mi | Gas 2.4L turbo (T24A-FTS), and the hybrid chart lists plugs for the T24A-FTS only |
| Automatic transmission fluid | Inspect at 30,000, 60,000, 90,000 mi... | Replace at 60,000 mi if you tow, load heavily, or do extensive idling and low-speed driving (taxi or delivery use) |
| Rear differential oil (AWD gas) | Inspect 15,000, replace 30,000, inspect 45,000, replace 60,000 mi | Replace every 30,000 mi |
| Transfer case oil (AWD gas) | Inspect 15,000, replace 30,000, inspect 45,000, replace 60,000 mi | Replace every 30,000 mi |

Special Operating Conditions
Toyota says to do these extra items only if most of your driving is under the condition:
- Dirt or dusty roads: change the oil and filter every 5,000 miles or 6 months, inspect the engine air filter at every visit, and inspect ball joints, drive shaft boots and steering linkage more often.
- Towing, a car-top carrier or heavy loading: torque the chassis and body nuts and bolts at every visit, torque the propeller shaft bolts, replace the rear differential and transfer case oil (gas AWD), and replace the automatic transmission fluid at 60,000 miles. Extensive idling and low-speed driving, as in taxi or delivery use, also triggers the 60,000-mile transmission fluid replacement.
- Road salt: the chart adds propeller shaft bolt torque.
Towing owners should read the towing guide for the ratings.
Oil Grade and Capacity
The gas and Hybrid MAX 2.4L turbo take SAE 0W-20 (5.6 qt with filter) and the 2.5L Hybrid takes SAE 0W-8 (4.5 qt with filter). Details are in the specs guide.
Warranty at a Glance
| COVERAGE | TERM |
|---|---|
| Basic warranty | 36 months or 36,000 miles |
| Powertrain warranty | 60 months or 60,000 miles |
| Hybrid system (Hybrid and Hybrid MAX) | 8 years or 100,000 miles |
| Hybrid battery | 10 years or 150,000 miles |

Whichever comes first applies to the mileage terms. Toyota's guide says the vehicle must be maintained to keep coverage intact, and that you may have the work done by a dealer or another service provider, and keep records. The emissions warranty covers spark plug service.

The front-wheel-drive gas truck gets 21 city / 28 highway / 24 combined, the 2.5L Hybrid FWD 37 / 34 / 36, and the Hybrid MAX 26 / 27 / 27. At EPA combined, a 2.5L Hybrid AWD burns about 441 gallons over 15,000 miles against 652 for a gas AWD LE/XLE, a difference of about 211 gallons a year.

The gas Grand Highlander takes 5.6 qt of 0W-20 oil, the 2.5L Hybrid takes 4.5 qt of 0W-8, and the Hybrid MAX takes 5.6 qt of 0W-20.

Toyota Grand Highlander Problems: NHTSA Complaints
NHTSA holds 314 complaints on the Toyota Grand Highlander: 235 for the 2024 model year and 79 for 2025. The 2026 truck has none on file yet. The most-mentioned components are power train (67), engine (51) and fuel/propulsion system (47), after a large "other" bucket (80). About 35 complaint texts mention stalling, shutting off or losing power, and about 36 mention hesitation, jerking or lurching. Only 2 of the 314 mention the turbo, so the complaint data does not show a turbo failure pattern. Complaints are voluntary and unverified.
Toyota Grand Highlander Recalls: Every Recall 2024–2026
NHTSA lists 7 recalls on the Toyota Grand Highlander for model years 2024 to 2026. The two most serious are both on the 2026 model: 26V437 (rear axle carriers that may break, July 2026) and 26V598 (front steering knuckles that may crack, September 2026). The 2024 model has the curtain air bag recall (24V461). A rearview camera software recall (25V744) and an instrument panel recall (25V595) cover 2024 and 2025 trucks. Two load label recalls (24V548, 26V179) are label swaps. Check your VIN at nhtsa.gov/recalls.
