Recalls & safety

Pros & cons

Pros

  • Genuine off-road capability with full-time 4WD, a locking center differential and available height-adjustable suspension.
  • Smooth, quiet 4.7L V8 with confident towing and a refined Lexus ride.
  • Legendary body-on-frame durability; these 4.7L V8 GX470s routinely reach 250,000-300,000 miles with maintenance.
  • High-quality, comfortable interior with strong long-term resale value.

Cons

  • Tight, awkward-to-access third-row seating.
  • Side-hinged rear cargo door swings out toward the curb rather than lifting up.
  • Age-related dashboard cracking, clearcoat peeling and secondary-air-pump repairs to budget for.
  • Poor fuel economy (roughly 15-18 mpg) and it requires premium gasoline.
  • Dated infotainment and electronics by modern standards.
