Overview

The 2004 Toyota 4Runner is a midsize, body-on-frame SUV built for drivers who want true truck-like durability with everyday comfort. It’s part of the fourth-generation 4Runner (2003–2009), introduced with a major redesign that improved on-road refinement while keeping strong off-road capability. Ideal for families, outdoor enthusiasts, and anyone who needs towing and long-term dependability, it sits in the market as a more rugged alternative to many car-based crossovers. With available V6 and V8 power and proven 4WD hardware, the 2004 4Runner remains a popular used SUV choice.

Key Features

1) Engine choices: A 4.0L V6 (1GR-FE) producing around 245 hp is standard, with an available 4.7L V8 (2UZ-FE) around 235 hp for stronger towing and low-end torque. 2) Available 4WD systems: Many models offer a capable 4WD setup, and certain trims include features like a Torsen center differential and low-range gearing for confident traction in snow, dirt, and trails. 3) Strong towing capability: Properly equipped models can tow in the 5,000 lb range (V6) and up to about 7,000 lb (V8), making it a solid option for small boats and campers. 4) Practical interior and cargo: A roomy cabin with an upright driving position, a large rear cargo area, and a rear roll-down window that’s great for ventilation, pets, and hauling long items. 5) Safety and daily drivability upgrades: The fourth-gen platform brought a more stable ride and improved handling versus earlier models, while still retaining the rugged ladder-frame construction many buyers want.

Common Issues & Reliability

Shoppers often search “2004 Toyota 4Runner reliability” because these SUVs are known for longevity, but there are a few common complaints worth watching. First, cracked exhaust manifolds and related exhaust leaks are frequently reported, often showing up as a ticking noise on cold start and sometimes appearing around 100,000–200,000 miles depending on climate and driving. Second, the X-REAS suspension system (if equipped) can develop leaks with age; when it fails, owners notice a bouncy ride or uneven damping, commonly after 100,000+ miles, and repairs can be expensive because the system is linked corner-to-corner. Third, brake issues are a recurring theme in “2004 Toyota 4Runner problems” discussions—some owners report warped front rotors, pulsation under braking, or caliper sticking, often between 60,000–120,000 miles depending on driving habits and parts quality. Finally, rust can be a serious concern in salt-belt states, especially on the frame and underbody; heavy corrosion can turn a solid SUV into a poor purchase even if the engine runs strong.
