What years of 4Runner are the most reliable?

The most reliable 4Runner years are generally the 2003–2009 models from the fourth generation, with the 2010–present fifth generation also offering strong long-term dependability. In practice, a well-maintained example from either generation can deliver many miles of trouble-free service, but reliability varies with maintenance history and climate-driven wear.

Reliability by generation

Fourth generation (2003–2009)

Among used 4Runners, the 2003–2009 period is widely regarded as the most dependable due to a straightforward 4.0L V6 drivetrain, durable construction, and fewer model-year-specific quirks. The engine’s timing is chain-driven, which reduces belt-related maintenance, and many owners report long lifespans with minimal major repairs.

• Excellent long-term reliability profile across most maintenance histories


• Durable 4.0L V6 (1GR-FE) with timing chain


• Relatively simple electronics compared with later models, contributing to easier maintenance

In practice, these years are favored by buyers seeking a rugged, long-lasting used SUV, especially when rust is not a major factor.

Fifth generation (2010–present)

The current generation has built upon Toyota’s reliability reputation with strong overall dependability, modern conveniences, and proven off-road capability. While not without maintenance costs at higher mileages, reliability remains a strong point for most model years, particularly after incremental updates over the 2010s. As of 2024–2025, the fifth generation continues to be viewed as a dependable option with a favorable maintenance profile when properly cared for.

• Consistently solid reliability scores in owner surveys


• Robust drivetrain with a design that supports long-term durability


• Most common issues relate to wear items and electronics rather than fundamental failures

Overall, the fifth generation remains a dependable choice for buyers seeking modern features plus proven durability, provided the vehicle has a thorough service history.

What to check before buying a used 4Runner

Before purchasing any used 4Runner, verify maintenance history and inspect key systems that influence long-term reliability.

• Service records demonstrating regular oil changes, transfer case and differential fluids, and timing-chain-related maintenance if applicable


• Frame and underbody condition for rust, especially in northern or coastal climates


• Rust on exhaust components, fuel lines, suspension parts, and any prior body work


• Drivetrain checks: 4WD engagement, transfer case operation, and ABS/brake system condition


• Electrical systems: gauges, infotainment, power windows, and lighting functionality

A careful inspection together with a vehicle history report (such as CARFAX or AutoCheck) can help identify the most reliable used examples.

Summary

For buyers prioritizing reliability, the 2003–2009 fourth-generation 4Runners stand out as the most consistently dependable across history, with the 2010–present fifth generation also delivering strong long-term reliability. The key to maximizing durability is choosing a well-maintained vehicle with thorough service records and addressing wear items proactively as mileage climbs. Across both generations, regular maintenance, rust prevention, and careful pre-purchase inspections are essential to ensuring years of dependable service.

What is the best year to buy a used 4Runner?

The best used 4Runner years are generally considered to be the later fifth generation (2014-2024) for modern tech, the third generation (1999-2002) for a balance of classic reliability and features, and the fourth generation (2008-2009) if you want the available V8 engine. However, specific model years are often recommended for different priorities like reliability, updated tech, or specific engines.

Top recommendations by generation

• Fifth Generation (2010-2024):
  • 2014-2024: This range is great for updated infotainment and driver-assist features, with the later years receiving a facelift that many prefer. The 2017 model is frequently cited as a top-rated year for its balance of features and reliability. 
  • 2010-2013: These earlier fifth-gen models are still a solid choice and can be found at a lower price point, while still offering many off-roading features. 
• Fourth Generation (2003-2009):
  • 2008-2009: These are often cited as the best years for this generation, especially if you're looking for the more powerful and reliable V8 engine option. This generation also offered an available third row of seats. 
  • Note: Be cautious with earlier fourth-gen models, as some years, especially 2003-2005, have a higher number of complaints, often related to rust. 
• Third Generation (1996-2002):
  • 1999-2002: The later years of this generation are recommended over the earlier models because Toyota ironed out some of the kinks, such as ball joint issues, in later production years. 
  • Overall: This generation is considered the start of the modern 4Runner, with its improved design, more spacious interior, and the reliable 3.4L V6 engine. 

Other considerations

• Manual Transmission: If you specifically want a manual transmission, look for models from the third generation (1996-2000) or earlier generations, as the fifth generation only offered a five-speed automatic. 
• Reliability: Generally, all 4Runner generations are known for their excellent long-term reliability. However, models with lower mileage are less likely to have issues, so always check the vehicle history report. 
• Price: Be prepared for a higher price tag on 4Runners, especially for later model years, due to their strong resale value and reputation for durability. 

What year did the 4Runner have a bad frame?

If you own a Toyota 4Runner that was manufactured between 2003 and 2009, your vehicle is most likely having a defective undercarriage that is prone to excessive and premature rusting. The following are the car models that fall in this category: Toyota 4Runner SR5. Toyota 4Runner Limited.

Which Toyota Four Runner is the best?

Best for off-road 

• TRD Pro: The most capable off the factory line, with enhanced features like FOX® shocks and specialized suspension for trails.

Best for on-road comfort 

• Limited: Designed for on-road performance with a more refined interior and features like the X-REAS sport suspension. It's the quietest and most comfortable for daily driving. 

Best for a balance of both
