Toyota Grand Highlander Reliability Review. What Makes This Family SUV a Smart Buy?
- The 2024 Toyota Grand Highlander is the most problematic model year, with seven recalls and a relatively high number of owner complaints.
- Reliability improves significantly for 2025, earning an excellent rating with far fewer recalls and complaints.
- The 2026 Grand Highlander currently holds an excellent reliability score with no reported recalls or owner complaints.
The Toyota Grand Highlander is a first-generation nameplate that launched for 2024 with all the opportunities and all the challenges that a brand-new vehicle platform introduces. First-generation vehicles from any manufacturer carry an inherent reliability uncertainty that simply cannot be resolved without real production volume and real owner experience accumulated across time — and the Grand Highlander’s three-year production history confirms this pattern precisely: a difficult 2024 launch year, a significantly improved 2025 model year and a 2026 model that begins with the cleanest early production reliability signal of the nameplate’s brief history. Understanding where each model year stands in this trajectory is the most practically important reliability research any Grand Highlander buyer can conduct before purchase — whether new or used.
The Cross-Generation Reliability Score: A Three-Year Average of 73 Out of 100
The Toyota Grand Highlander’s average reliability score of 73 out of 100 across the 2024, 2025 and 2026 model years reflects the specific mathematical consequence of a challenging launch year pulling down the average that the 2025 and 2026 improvements have established.
This average conceals a meaningful and important trend: the nameplate is improving rapidly year-over-year in precisely the pattern that Toyota’s quality improvement processes typically produce for first-generation nameplates. The 2024 model at 69 out of 100 with 7 recalls and 171 complaints represents the most active quality concern period. The 2025 model at 80 out of 100 with 3 recalls and 33 complaints represents one of the most dramatic single-year reliability score improvements available across any nameplate in the 2026 model year landscape. The 2026 model at 80 out of 100 with zero recalls and zero complaints represents the best early production signal the nameplate has produced.
For buyers who specifically want to understand where the Grand Highlander stands today rather than as an historical average, the 2025 and 2026 data is far more practically relevant than the three-year average — and both recent model years position the Grand Highlander as a competitive and legitimate purchase choice within the three-row midsize SUV segment.

The 2024 Model Year: Understanding the Launch Year Challenges
The 2024 Toyota Grand Highlander’s 7 recalls and 171 owner complaints represent one of the more active launch-year quality profiles in Toyota’s recent production history — a result that reflects both the complexity of introducing an entirely new platform and the heightened scrutiny that a high-profile new nameplate receives from early adopters who are more likely to document and report issues.
The 171 owner complaints across 2024 production include powertrain concerns as the largest documented category, followed by unknown or other categories and structural concerns. The complaint rate of 23.8 per 10,000 sold is the metric that most accurately conveys the 2024 model’s relative reliability challenge — normalising complaints against production volume to produce a comparison metric that is independent of how many vehicles were sold.
The 2024 model’s recalls include the instrument panel software issue affecting multiple Toyota models — where the instrument panel may fail to display vehicle speed, brake system warnings and tyre pressure warnings at startup. This recall is resolved through a dealer software update at no cost. The load carrying capacity modification label recall — affecting vehicles where the label displays inaccurate added weight values — is similarly resolved through a label replacement at no cost.
For buyers evaluating 2024 Grand Highlander used examples, verifying that all applicable recalls have been completed through the NHTSA VIN-specific recall lookup is the essential due diligence step before finalising any purchase. The 2024 model’s higher complaint volume and recall count are legitimate reliability concerns that should factor into the used price expectation and the buyer’s comfort level with early-generation ownership uncertainty.
The 2025 Model Year: The Most Significant Reliability Improvement
The 2025 Toyota Grand Highlander’s designation as much more reliable than other cars from the same model year — based on comprehensive owner survey data covering over 380,000 vehicles — is the most practically significant single reliability finding in the nameplate’s three-year history. This above-average designation for the 2025 Grand Highlander directly validates Toyota’s engineering response to the 2024 launch year quality concerns through the manufacturing improvements and component revisions that reduced owner-reported issues from 171 to 33.
The specific complaint reduction from 171 in 2024 to 33 in 2025 — an 81 percent reduction in owner complaint volume — is one of the clearest quality trajectory improvements documented across any Toyota nameplate in a single model year transition. The 2025 model’s 3 recalls versus 2024’s 7 confirms that this improvement extended beyond reduced owner reporting into the formal recall activity that Toyota’s quality engineering processes initiate when systematic issues are identified.
The 2025 Grand Highlander’s 5-star NHTSA overall safety rating validates both the structural design and the active safety systems as producing genuinely outstanding real-world safety outcomes across standardised crash testing protocols. Frontal crash at 4 stars, side crash at 5 stars and rollover at 4 stars with a 17.4 percent rollover probability are specific safety credentials that complement the reliability improvement story with independent safety validation.
The owner-reported trouble spots for the 2025 Grand Highlander concentrate in powertrain, unknown or other and structure categories — with one specific documented complaint concerning child safety lock behaviour requiring multiple unlock button presses to disengage. These issues are qualitatively different from the 2024 model’s more numerous and more severe documented concerns, reflecting a vehicle that has addressed its most serious launch-year issues while retaining some minor refinement areas for continued improvement.

The 2026 Model Year: The Cleanest Early Production Signal
The 2026 Toyota Grand Highlander carries 0 recalls and 0 owner complaints on file — the most positive early production reliability signal the nameplate has produced and the data that most directly supports the 2026 as the safest model year choice for buyers whose primary criterion is reliability confidence.
The 80 out of 100 Excellent reliability score for the 2026 model — matching the 2025 model’s score despite carrying zero complaints and zero recalls — reflects the prediction methodology that incorporates the 2024 and 2025 generation’s accumulated reliability data alongside the 2026 model’s own early signals to produce the most complete reliability assessment available.
The 2026 Grand Highlander Hybrid specifically carries 2 active recalls — both related to the load carrying capacity modification label and the panoramic view monitor camera system — resolved through dealer label replacement and software updates at no cost. For 2026 Hybrid buyers, verifying these recalls are completed is the appropriate pre-purchase or post-purchase action.

The Reliability Context: How Grand Highlander Compares to Standard Highlander
The Toyota Highlander’s cross-generation reliability average of 84 out of 100 across 2018 through 2026 production is meaningfully higher than the Grand Highlander’s three-year average of 73 out of 100 — a difference that reflects the standard Highlander’s longer production history having accumulated the quality refinements across multiple generations that the Grand Highlander is still working through in its first generation.
The 2025 Grand Highlander’s 80 out of 100 score, however, equals the best single-year score the standard Highlander has achieved in recent production — confirming that the Grand Highlander has already reached competitive reliability with the established nameplate in its best year rather than requiring multiple additional model years to close the gap. The nameplate’s reliability trajectory from 69 in 2024 to 80 in 2025 to 80 in 2026 is among the steepest positive improvement curves available in the three-row midsize SUV segment.
