is it a safe used buy?

A genuinely capable, body-on-frame off-roader paired with Toyota's most dependable V6 — about as confident a used SUV purchase as this entire catalogue covers.

How the engine fits this car

The 4Runner's genuinely capable body-on-frame platform is an easy, unstressed load for this V6 — never strained, which is a large part of why both engine and vehicle have such a strong reputation among off-road enthusiasts and daily drivers alike.

This platform shares its core drivetrain with the related Tacoma of the same era — worth cross-referencing if you're also considering that truck.

Toyota 4Runner (4.0L)-specific pros and cons

This is about the car itself — for engine-specific failure points, see the dedicated engine page below.

WHAT HOLDS UP WELL

Engine has an exceptional long-term reliability reputation, detailed on its own page
Genuinely capable body-on-frame off-road platform with a huge aftermarket and specialist support community
Strong resale value reflects broad, sustained buyer confidence in this model's dependability
Simple, robust mechanicals throughout, not just the engine

WHAT TO WATCH

Fuel economy is modest, typical of a body-on-frame SUV of this era
Ride quality is firmer than more car-based crossover rivals, an inherent trade-off of the platform
Third-row seating (where fitted) is cramped, more suited to children
Infotainment and interior tech feel dated by modern standards, expected for the car's age

Pre-purchase checklist for this generation

Beyond general maintenance history, there's genuinely little engine-specific risk to flag on this combination.

Ask about off-road use history, and inspect the undercarriage for related wear or damage accordingly.

Check for rust around the frame and undercarriage, especially on examples from regions that salt roads in winter.
