Toyota Grand Highlander 2024–2026
Summary
- 3 model years in 1 generation, 371 owner complaints in total.
- No model year holds enough complaints in its first three years to be compared with the others.
- These are complaint counts, not failure rates: they are not divided by how many cars were sold, because no public source reports U.S. sales by model year.
- Half of the complaints that give a mileage were filed by 14,000 miles (29 of them give one).
- Owners reported 9 crashes, 1 fire, 9 injuries and 1 death across these model years.
- 7 recalls and 1 federal investigation cover these model years; 1 investigation is still open.
Why there is no page per model year
A model year earns its own page when four sources cover it, it holds at least 50 complaints, and it can either be compared with the other years of its generation or shows one system in 40% or more of the complaints that name a component. No Grand Highlander year clears that bar: the highest count is 245 complaints, in 2024. Rather than publish a thin page for each year, everything known about this model is on this page.
2024–2026
Each year is counted over the same span: complaints received up to two calendar years after its model year. A year is compared only when that span is over and it holds at least 50 complaints. Fewer than three years of this generation are comparable, so no year is named.
| Model year | All complaints | First three years | Most reported system | Note |
|---|
| 2024 | 245 | 245 | Powertrain | not compared |
| 2025 | 80 | 80 | Powertrain | not compared |
| 2026 | 46 | 46 | Body & Structure | not compared |
Every model year
A model year gets its own page when four sources cover it, it holds at least 50 complaints, and it either compares with the other years of its generation or shows one system in 40% or more of the complaints that name a component. The rest are listed here with their figures.
| Model year | Complaints | Recalls | Investigations | Bulletins | Combined MPG | Page |
|---|
| 2024 | 245 | 4 | 1 | 226 | 22–36 | listed here |
| 2025 | 80 | 3 | 1 | 38 | 22–36 | listed here |
| 2026 | 46 | 3 | 1 | 25 | 22–36 | listed here |
What owners report across all years
| System | Complaints | Share | Median mileage |
|---|
| Powertrain | 75 | 24% | 4,000 mi |
| Engine | 64 | 21% | 15,000 mi |
| Fuel & Propulsion | 58 | 19% | 16,455 mi |
| Body & Structure | 38 | 12% | 12,200 mi |
| Airbags | 34 | 11% | 10,000 mi |
Shares are over complaints that name a component; a complaint naming several systems is counted under each.

Service bulletins
Toyota issued 289 service bulletins covering these model years, most often about unknown or other.
A bulletin tells dealers how to fix a known condition. It is not a recall and not a defect finding. Most bulletins cover several model years at once, so a bulletin listed here may not be specific to one year. The number of bulletins tracks how long and how widely a model was sold, so it is not a measure of reliability.

How to read this page
Complaint counts are not failure rates. A model that sells more cars draws more complaints, and owners file more after news coverage or a recall. That is why years are compared only with other years of the same generation, over the same span, and never with other models.
