The fifth-generation Toyota 4Runner recently tied for the top spot in the JD Power Vehicle Dependability Study. This ranking reflects the performance of models sold in the United States from 2010 through 2024.
Why it matters
The vehicle's consistent reliability rating highlights the long-term value of its mechanical design, which has kept costs significantly lower than the industry average for SUV repairs. As the manufacturer shifts toward turbocharged engines in the sixth generation to meet emissions standards, the long-standing performance of the 4.0-liter engine remains a benchmark for owners.
The fifth-generation model maintains an average annual maintenance cost of $514 and a five-year depreciation rate of 25%. These figures are supported by the 4.0-liter V6 engine, which produces 270 horsepower and 278 pound-feet of torque.
The players
Toyota
A global automotive manufacturer known for producing the 4Runner and transitioning to smaller turbocharged engine platforms to comply with emissions standards.
JD Power
A consumer research firm that conducts longitudinal vehicle dependability studies based on three-year ownership periods.
The details
The fifth-generation 4Runner achieved its reliability rating through a design that prioritizes simple, naturally aspirated components over complex systems to minimize failure points. It utilizes a ladder-frame chassis paired with a five-speed automatic transmission and mechanical gear-locking four-wheel drive. In contrast, the upcoming sixth-generation model moves to a turbocharged 2.4-liter four-cylinder engine and an eight-speed automatic transmission.
Timeline
2010 to 2024 marks the availability of the fifth-generation Toyota 4Runner.
2025 is the launch year for the sixth-generation 4Runner.
10-year period represents the estimated scope for maintenance and repair cost projections.
The Home Front
This performance ranking situates the 4Runner within a broader automotive trend where manufacturers are retiring proven, naturally aspirated powerplants in favor of forced induction. Understanding these reliability metrics is essential for households managing long-term transportation budgets.
Owners should continue to follow the manufacturer-recommended maintenance schedule to keep annual costs near the $514 average. When evaluating future vehicle purchases, consider how the shift from naturally aspirated engines to turbocharged hybrid systems might impact long-term repair accessibility.
The takeaway
The 4Runner's reliability is tied to its mechanical simplicity, which has successfully kept ownership costs lower than the industry average for over a decade. Prospective buyers should note that future repair costs for newer turbocharged models may differ as the platform transitions away from the 4.0-liter V6.
