2024 Toyota Grand Highlander — reported problems
CarFaultIQ holds 361 evidence records for the 2024 Toyota Grand Highlander, drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 343 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.
- Powertrain (transmission & drivetrain)47 (13.7%)Official recall records for this system: 1, covering model years 2026.
- Engine37 (10.8%)
- Fuel system36 (10.5%)
- Air bags (restraint system)29 (8.5%)Official recall records for this system: 2, covering model years 2024.
- Speed control & accelerator23 (6.7%)
- Electrical system22 (6.4%)Official recall records for this system: 1, covering model years 2024–2025.
Other / uncategorized: 57 classifications (16.6%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.
These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.
What the records are about, by source
Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.
- Owner complaints (644 records, model years 2024–2026) are most frequently classified under: powertrain (transmission & drivetrain), engine and fuel system.
- Manufacturer communications (360 records, model years 2024–2026) are most frequently classified under: electrical system, body & structure and engine.
"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records
Mileage reported when the issue occurred
- 22reports included a mileage
- 17,661average of those mileages
This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.
Evidence by model year
Records held per model year. Select a year to narrow this page to it.
Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.
