What is the best years for Toyota 4Runner?

Toyota 4Runner fans prize rugged reliability and off-road ability. The best model years depend on what you value most—durability and value, or modern comfort and safety features.

For most buyers, the late-1990s to early-2000s third-generation 4Runners (1996–2002) are widely regarded as the best all-around for reliability and after-market support. If you want more modern conveniences without sacrificing capability, the mid-2000s fourth generation (2003–2009) strikes a strong balance. For updated safety tech, ride comfort, and daily usability, the fifth generation (2010–2023/24) is the best option, with mid‑decade models representing the best value and refinement in this era.

Generation-by-generation snapshot

What to look for when buying a used 4Runner

Regardless of generation or year, certain checks help ensure you get a solid vehicle with long-term reliability.

• Pre-purchase inspection by a qualified technician familiar with Toyota SUVs.


• Rust assessment: pay close attention to frame rails, underbody mounts, door bottoms, and wheel arches, especially in regions that use road salt.


• Service history: verify regular maintenance, timing chain/belt maintenance if applicable, and transfer case/4WD system servicing.


• Head gasket, cooling system, and thermostat condition on older engines.


• Suspension components, steering linkage, ball joints, and CV joints for wear, plus proper alignment and tire condition.


• Electrical and safety systems: airbags, ABS, traction control, and infotainment software updates where relevant.

Thorough inspection and documented maintenance history are more predictive of long-term reliability than model year alone.

Summary

For the broadest consensus on longevity and value, late-1990s to early-2000s third-generation 4Runners (1996–2002) are often recommended as the best overall; they combine simple mechanics with strong aftermarket support. If you prioritize modern comfort and safety, the mid-2010s fifth-generation models (roughly 2014–2018) offer the best balance of refinement and capability, while still delivering Toyota-level durability. For a rugged, budget-friendly path with classic 4Runner DNA, the older second generation (1989–1995) remains appealing, provided you’re prepared for the age-related maintenance those units require. Always pair year selection with a diligent pre-purchase inspection and a complete service history to maximize value and reliability.
