Toyota 4Runner Reliability by Year

Every 4Runner model year from 2004 to 2025, scored on reported failures weighted against how many were sold — and ranked against every other Mid-Size SUV of the same year.

The short answer

Best model year
2023
#1 of 67 that year
Year to avoid
2004
#21 of 26 that year
Latest scored
2025
#28 of 66

Across 22 scored model years the 4Runner needs fixing less often than its class, and repairs cost about what you would expect. The spread between years is what matters: 2023 is its strongest, 2004 its weakest.

Every model year, scored

Longer bar is better. Rank is against every Mid-Size SUV sold that same model year.

The line held a weak position through 2004, ran middling in 2005, and has been strong from 2006 on. Recent years have been slipping. This 2025 car falls in a strong stretch.

What tends to break

All 12 systems, measured against the class average for each model year.

Every 4Runner model year is scored across 12 separate systems — engine, transmission, brakes, electrical, steering and suspension, structure, interior, and five more. Each system is compared against how often that same system fails on the average Mid-Size SUV of the same year, so a common failure is judged against how common it is everywhere else.

Across the last three model years (2023–2025), the trouble concentrates in one place: braking system. That system draws issue reports more often than the same system on the average Mid-Size SUV of its year — which changes what you should be inspecting before you buy.

Where does this data come from?

Failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes so a high-volume model is not penalised for selling well, then benchmarked within segment and model year.

How this was built. Scores derive from failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes and benchmarked within segment and model year. We measure two separate things: Fix Frequency — how often a vehicle needs fixing — and Fix Severity — how costly those fixes are. These figures describe a model line, not the specific vehicle in front of you; trim, mileage and service history still decide an individual car.
