Platform Heritage

The Toyota Grand Highlander is a mid-size crossover SUV with three-row seating produced by Toyota since 2023. The Grand Highlander was introduced for the North American market on February 8, 2023. While sharing the nameplate and the GA-K platform with the regular Highlander, the Grand Highlander is longer, taller, and wider, and features entirely different exterior and interior styling. In the North American market, the Grand Highlander is positioned between the smaller Highlander and the larger Tundra-based Sequoia. It is available in five grade levels: XLE, Limited, and Platinum since 2023, Nightshade since 2024, and LE starting in 2025. The Lexus equivalent is known as the Lexus TX, and is also exclusive to the North American market.

  4. Run a MotoMetrics on-site scan for Toyota Grand Highlander before signing the bill of sale.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
