Is the 2002 Toyota 4Runner reliable?

Yes, the 2002 4Runner is widely regarded as reliable thanks to its truck-based design and proven engines, but condition and maintenance history matter a lot because of the vehicle’s age.

What are the most common 2002 Toyota 4Runner problems?

The most common issues include frame rust, front suspension wear (especially lower ball joints), brake wear complaints, and age-related leaks or cooling system wear on higher-mileage vehicles.

Are maintenance costs high for a 2002 4Runner?

Costs are usually moderate for an older SUV; parts are widely available, but budgeting for suspension refreshes, brake work, and rust mitigation is smart on any 20+ year old 4Runner.

What are the best years to buy for this generation of 4Runner?

Many buyers target 1999–2002 models within the third generation due to incremental updates and the well-regarded 3.4L V6, but overall condition and rust history are more important than the exact year.

What should I check before buying a 2002 Toyota 4Runner?

Check the frame and underbody for rust, confirm smooth steering and tight front suspension, test 4WD engagement (if equipped), look for cooling system health (stable temps, clean coolant), and review service records for consistent maintenance.
