Recalls & safety

Pros & cons

Pros

Serious off-road hardware: full-time 4WD, Torsen center diff, available KDSS, Multi-Terrain Select and Crawl Control.
Comfortable, durable, high-quality cabin.
Refined, quiet 4.6L V8 with a 6,500 lb towing rating.
Outstanding long-term reliability and class-leading resale, built on Toyota Land Cruiser Prado underpinnings.

Cons

Side-hinged tailgate swings out curbside instead of lifting up.
Limited cargo space behind the third row.
The 2010 launch year carries a stability-control recall reputation; verify recalls on early trucks.
Thirsty 4.6L V8 (about 15-18 mpg) that requires premium fuel.
Dated infotainment, especially on pre-2020 model years.
